DEFINITIONS

Certificate of Compliance must consist of a certification, signed

by an authorized employee of the producer, that the material

shipped meets the requirements of this specification and any

supplementary requirements cited in a contract or order under

which it was purchased.

Independent Inspection relates to examination of a "lot" of

material by an independent inspector employed by a commercial

agency.

Inspection means an examination of material in sufficient detail

to insure conformity with all phases of the specification under

which it was purchased. Inspection prior to treatment must be

made after the products are manufactured and ready for treatment.

If poles are trimmed to length, inspection prior to treatment may

be done prior to framing, providing inspection hammer brands are

not removed during framing. When framing is done after white

inspection, the framing must be inspected after treatment.

Producer is used to describe the party who manufactures and

treats poles.

Purchaser refers to either the REA borrower or to a contractor

acting as the borrower's agent, except where a part of the

specification specifically refers to only the borrower or the

contractor.

Quality control designee refers to an individual designated by

the producer to be responsible for quality control.

Reserve treated stock consists of timber products treated in

accordance with this specification, prior to and in anticipation

of the receipt of specific orders, and held in storage ready for

immediate shipment.

Supplier is a term used interchangeably with producer.

Transmission poles - Unless otherwise indicated, any pole 50 feet

or longer is designated as a transmission pole.

Treating charge refers to all the material treated in a cylinder

at one time.

Treating plant is the organization that applies the preservative

treatment to the poles.

1. SCOPE

1.1 This specification describes the minimum acceptable quality

of wood poles, stubs, telephone pedestal stubs, and anchor logs

(hereinafter called poles, except where specifically referred to

as stubs or anchor logs) purchased by or for REA borrowers, and

the plans of procurement under which they may be purchased.

Where there is conflict between this specification and any other

specification referred to herein, this specification shall

govern.

1.2 The requirements of this bulletin implement contractual

provisions between REA and borrowers receiving financial

assistance from REA. The contractual agreement between REA and

its borrowers requires the borrower's system be constructed in

accordance with REA accepted plans and specifications. Each REA

electric borrower shall purchase only wood poles produced in

accordance with the specifications.

1.3 Each REA electric borrower shall require each contractor, in

writing, to agree to furnish only materials produced in

accordance with this bulletin.

3. GENERAL STIPULATIONS

3.1 Various requirements relating to quality control and

inspection are to be found in REA Bulletin 1728H-702, REA

Specification for Quality Control and Inspection of Timber

Products. These requirements shall be followed. Provisions of

this specification and American National Standards Institute

(ANSI) 05.1, 1987, "American National Standard Specifications and

Dimensions for Wood Poles," which are positive in their wording,

shall not be interpreted or subjected to judgment by the quality

control designee or an independent inspector. Judgment, although

used by quality control personnel and independent inspectors,

shall not be the basis for acceptance of material which does not

conform to the minimum requirements of this specification.

3.2 Each purchaser shall use a written purchase order to

purchase material for use in REA financed systems in order to

insure compliance with the standards and specifications. The

written purchase order shall contain a provision that

specifically requires the producer to comply with these

provisions. The purchase order shall contain a provision that

specifically requires the producer to make the treating plant and

storage areas available, during normal business hours, in order

for representatives of either the purchaser or REA to inspect

such to determine compliance with the standards and

specifications.

3.3 Plans which are acceptable for supplying poles under this

specification include:

3.3.1 Insured Warranty Plan: Under this plan, the producer

furnishes poles meeting this specification and furnishes a

warranty. The warranty shall be issued by an insurance company

under terms and conditions acceptable to REA. The insurance

company shall submit its plan for assuring quality control to REA

for specific approval prior to issuance of these warranties.

Currently, there are no insurance policies in effect.

3.3.2 Independent Inspection Plan: Under this plan, the

producer furnishes poles meeting this specification, and all

poles are then inspected by a qualified independent inspector in

accordance with REA Bulletin 1728H-702, REA Specification for

Quality Control and Inspection of Timber Products.

The REA borrower has the prerogative to contract directly with

the agency for the inspection service. The borrower shall, where

practical, select the inspection agency so that the inspector's

continued employment is dependent only on performance acceptable

to the borrower. The borrower shall be responsible for ensuring

that the independent inspection is properly performed. The

selected agency shall not subcontract the service to any other

agency without prior written consent of the borrower.

The producer shall not interfere with the work of the inspector

except to provide notification of the readiness of material for
Bulletin 1728F-700

Page 7

inspection. When circumstances warrant, the producer may deal

directly with the agency. The producer shall not treat material

before it has been properly inspected in the white, as evidenced

by the inspector's hammer mark.

3.3.3 Quality Assurance Plans: Under such plans, the producer

furnishes poles conforming to this specification as monitored by

a quality assurance program acceptable to REA. REA borrower

groups or agents for borrower groups endeavoring to operate

Quality Assurance Plans shall submit their plans for assuring

quality control to REA for specific approval prior to contracting

with REA electric or telephone borrowers under such plans.

3.4 With the exception of reserve treated stock, all invoices

for treated timber products shall be accompanied by a copy of the

producer's Certificate of Compliance and either a copy of the

Independent Inspection Report, the Insured Warranty Certificate,

or, for other acceptable plans, a comparable certificate of

compliance. The certificate shall be presented to the purchaser

with the invoice. For reserve treated stock under the

Independent Inspection Plan, inspection reports shall be

available from the inspection agencies. The purchaser may obtain

these reports from the inspection agency after the purchaser has

provided the inspection agency with a list of the charge numbers.

(The charge number, as found on the butt, is defined in Appendix

A, paragraph 9.5.)

3.5 Quality control, as exercised by the plant quality control

designee, is an important component in the satisfactory

production of treated wood. If the purchaser considers the

quality control to be inadequate, the purchaser, or an inspection

agency which it retains, may, at the time of material inspection

at the plant, reject all material from the plant.

3.6 Poles failing to conform to any provision covered by this

specification shall not be shipped to the purchaser.

3.7 Poles shall be warranted to conform to this specification.

Any pole found not in conformance with this specification within

1 year from date of shipment to the purchaser shall be replaced

as promptly as possible by the producer. (Preservative retention

shall meet the requirements of the specification, as a minimum at

time of shipment to the borrower (see Table 10, Exhibit H). A

reduction in preservative retention of not more than 10 percent

shall be acceptable up to 30 days from date of delivery.)

3.8 The methods of inspection described herein and in REA

Bulletin 1728H-702, REA Specification for Quality Control and

Inspection of Timber Products, shall be used no matter which plan

is used in producing poles, i.e., Insured Warranty Plan,

Independent Inspection Plan or Quality Assurance Plans. The

number of poles actually inspected by monitors of quality control
Bulletin 1728F-700

Page 8

under the Insured Warranty Plan or a Quality Assurance Plan may

vary from the number of poles inspected under the Independent

Inspection Plan.

4. QUALITY CONTROL

4.1. Producers shall maintain plant and yard conditions that do

not promote decay. Producers shall maintain acceptable quality

control procedures as evidenced by the quality of the material

offered for inspection, or covered by an Insured Warranty or a

Quality Assurance Plan.

The quality control procedure of all plants that produce poles

under any of the plans described in paragraph 3.3 shall contain

at least the following elements:

4.1.1 Quality control shall be the responsibility of a competent

individual designated for that specific purpose (quality control

designee), together with such staff as may be required. The

quality control designee shall be qualified to make the necessary

inspections and perform chemical analyses and assays required by

this specification. The quality control designee shall verify

each step in the production before releasing the material to be

inspected by an independent inspector. The independent inspector

shall independently repeat the quality control designee's

inspections and tests.

4.1.2 An inspection agency performing quality control for a

producer shall not also act as the independent inspector of the

same producer's poles produced for REA borrowers.

4.1.3 Records, as described in this bulletin and in REA Bulletin

1728H-702, REA Specification for Quality Control and Inspection

of Timber Products, shall be maintained by the producer.

4.1.4 Poles not meeting specifications at any stage shall be

withdrawn from production by the quality control designee and

shall not be offered for acceptance or shipment under any plan

until defects have been corrected. Poles not meeting the

requirements for penetration or retention of preservative may be

re-treated twice only, provided that the total allowable

preservative steaming times and temperatures are not exceeded.

The identification brand shall be promptly removed from all

material found to be nonconforming, subject to the foregoing

provision for re-treatment.

4.1.5 The quality control designee and the independent inspector

shall both perform all examinations, tests, and assays,

individually and independently. Neither shall rely on the other

individual's results in the discharge of their duties.
Bulletin 1728F-700

Page 9

4.2 The producer shall provide the inspectors with full

information (drawings, etc.) relating to the requirements

contained in any purchase order which is supplementary to this

specification.

4.3 The producer shall maintain or have access to adequate

laboratory facilities at or very near the treating plant. All

chemical tests or analyses associated with the treatment shall be

independently performed in this laboratory by the quality control

designee, the borrower's independent inspector, or other Quality

Assurance Plan monitor. If acceptable to REA on a case-by-case

basis, the producer may use a central laboratory.

4.4 Inspection agencies shall maintain their own central

laboratory(ies) with a qualified staff capable of completely

analyzing the preservative and treatments they are inspecting.

The laboratory shall be equipped in accordance with AWPA

standards. If acceptable to REA, this central laboratory may be

used for the inspector's routine assays. When permission is

granted for the inspection agency to use this lab for routine

analyses (paragraph 4.3), the assays shall be run promptly, and

the results shall be made available the next working day.

5. RESERVE TREATED STOCK: Reserve treated stock shall be

subject to the following conditions:

5.1 Producers may treat material for reserve treated stock under

any of the plans (paragraph 3.3) and shall notify REA in advance

of their intention. The notification shall be submitted prior to

initial treatment of material for reserve stock, and shall be

submitted annually thereafter prior to the beginning of each

calendar year. The notification shall be addressed to the

Director, Electric Staff Division, Rural Electrification

Administration, Washington, DC 20250-1500. Producers shall

inform REA of (a) the locations of all storage or distribution

yards where reserve treated stock will be maintained, and (b) the

designation of the plan and the name of the selected inspection

agency, where applicable, which is to be used to provide reserve

stock. The producer shall notify REA promptly of any change in

the plan or inspection agency.

REA will acknowledge each notification of intent to treat

material for reserve treated stock under the REA specification.

Purchasers shall not purchase reserve treated stock from plants

that fail to comply with the above notification requirements.

REA acknowledgement of the plant's advance notice of intention to

treat material for reserve treated stock for the calendar year in

question shall be evidence of compliance with the notification

requirements.

5.2 No material treated with creosote, pentachlorophenol, or

Copper Naphthenate shall be shipped for use on an REA borrower's
Bulletin 1728F-700

Page 10

system later than 1 year following the treatment date branded on

the material, unless it complies as follows:

a. The material shall be reassayed by the producer. If

conforming to preservative retention requirements, as

shown in Table 10, Exhibit H, it may be shipped.

Reassayed poles shall be identified on the sawed butt

surface with a metal tag showing reassayed date. Such

poles shall be acceptable for shipment for 1 year from

the date of reassay.

b. If the material is below specification requirements

for preservative retention at the time of reassay for

shipment, the brand shall be removed and the material

reinspected, re-treated, and rebranded in accordance

with paragraph 8.5.

5.3 Waterborne treated poles need not be reassayed.

6. MATERIAL REQUIREMENTS: All poles shall conform to the

material requirements shown in Appendix A, which are primarily

extracted from ANSI 05.1-1987.

7. PRESERVATIVES: Preservatives shall be selected from one of

the following:

7.1 Creosote: Creosote shall conform to all requirements of

AWPA Standard P1 when analyzed in accordance with the methods in

AWPA Standard A1, sections 2, 3, 4, either 5 or 9, and 6.

7.2 Pentachlorophenol: Pentachlorophenol shall contain not less

than 95 percent chlorinated phenols and shall conform to AWPA

Standard P8 when analyzed in accordance with AWPA Standards A5 or

A9. The hydrocarbon solvents for introducing the preservative

into the wood shall meet the requirements of AWPA Standard P9

Type A, determined in accordance with reference ASTM standards

for physical properties.

7.3 Copper Naphthenate: Copper Naphthenate (CuN) concentrate

used to prepare wood-preserving solutions shall contain not less

than 6 percent nor more than 8 percent copper in the form of

Copper Naphthenate and shall conform to AWPA Standard P8 when

analyzed in accordance with AWPA Standard A5. The hydrocarbon

solvents for introducing the preservative into the wood shall

meet the requirements of AWPA Standard P9 Type A, determined in

accordance with reference ASTM standards for physical properties.

7.4 Waterborne Preservatives: Certain formulations of

waterborne preservatives are corrosive to metals. Purchasers are
Bulletin 1728F-700

Page 11

advised to contact suppliers for specific information on the

formulation they use.

7.4.1 Ammoniacal Copper Arsenate (ACA) and Ammoniacal Copper

Zinc Arsenate (ACZA) shall meet the requirements of AWPA Standard

P5, when analyzed in accordance with methods in AWPA Standard A2,

A9, or A11. Poles treated with ACA or ACZA shall be held by the

treater to allow a minimum of 30 days of drying time after

treatment before delivery to the borrowers.

7.4.2 Chromated Copper Arsenate (CCA) shall meet the

requirements of one of the formulations given in AWPA Standard

P5, sections 4, 5 or 6, and 10 and AWPA Standard C4. Tests to

establish conformity shall be made in accordance with AWPA

Standard A2, A9, or A11.

7.4.3 Treating solutions of the waterborne salts mentioned in

AWPA Standard P5, section 10 shall conform to the pH requirements

set forth in AWPA Standard A2, section 9.

7.4.4 Waterborne preservatives are available either as oxides

which form non-ionizing chemical compounds in the wood, or as

salts which leave ionizing compounds as well as non-ionizing

compounds in the wood. Salt formulations of a waterborne

preservative are more corrosive to metal than the oxide

formulations and may cause surface deposits.

Unless otherwise specified in the purchase order, the oxide

formulation of waterborne preservatives shall be supplied. If

visible surface deposits appear on the wood within the 1-year

warranted period, it is not in compliance with this specification

and shall be replaced by the producer.

7.4.5 Douglas-fir and western larch poles shall not be treated

with CCA preservatives.

7.4.6 Materials treated with waterborne preservatives shall be

free of visible surface deposits.

8. PRESERVATIVE TREATMENT

8.1 Conditioning Prior to Treatment:

8.1.1 Group "A" poles (see Table 1, Appendix A) which are

partially seasoned by natural air circulation shall be air dried

within the limits of paragraph 4.2.1, of Appendix A. Extreme

care shall be taken to insure that air seasoned poles do not have

pretreatment decay in them (refer also to paragraph 5.2 of

Appendix A). All poles in this category shall be further

artificially conditioned prior to treatment by processes such as

Boulton drying, steam conditioning or kiln drying, or heating in

the preservative.
Bulletin 1728F-700

Page 12

8.1.2 Group "B" or group "C" poles which are partially seasoned

by natural air circulation, kiln drying, or shed drying shall be

further conditioned by Boulton drying (group B, Table 1, Appendix

8.3 Treatment (Thermal Process), Full-Length Treatment: Western

larch, western red cedar, Alaska yellow cedar, lodgepole pine,

northern white cedar poles may be treated by the thermal process:

8.3.1 All poles treated by this process shall be adequately

seasoned by natural and artificial methods prior to treatment so

that specification requirements for penetration and retention are

met.

8.3.2 The temperature of the preservative during the hot oil

phase shall not exceed 235°F.

8.4 Results of Treatment:

8.4.1 Penetration and retention of preservative shall be tested

on borings taken at any point on the pole periphery

approximately:

a. Six inches to 12 inches above nominal ground line of

western red cedar, northern white cedar, and western larch

poles.

b. Within the zone 1 foot above to 1 foot below the brand

on all other species of poles.
Bulletin 1728F-700

Page 14

8.4.2 Retention of preservative shall be no less than that

specified in Table 10, as determined by:

a. Creosote by AWPA Standard A6.

b. Penta by AWPA Standard A5 or A9. Copper pyridine method

is required when timber may have been in contact with salt

water, and for all species native to the Pacific coast

region, unless the raw material invoice specifically states

that the material has not been in contact with salt water or

has been shown by analysis to have contained no additional

chlorides in the wood before treating.

c. Copper Naphthenate by AWPA Standards A5, A9, or A11.

d. Waterborne preservatives by tests in accordance with the

recognized standards methods for chromium, copper, zinc, and

arsenic ions listed in AWPA Standards A2, A7, A9, or A11.

8.4.3 Penetration of preservative, as determined in accordance

with AWPA Standard A3, shall not be less than that specified in

Table 10. Chrome Azurol S and Penta-Check shall be used to

determine penetration of copper containing preservatives and

penta, respectively. Under the Independent Inspection Plan, all

treating charges shall be tested for penetration using the

following sampling. Under the Insured Warranty and Quality

Assurance Plans, the frequency for testing penetration of charges

may vary according to the plan. When testing, the sampling shall

be as follows:

8.4.3.1 For poles with a circumference of less than 37.5 inches

at 6 feet from butt:

a. Bore 20 percent of poles in a charge or 20 poles from

charge, whichever is greater. Accept if 100 percent

conform; otherwise, bore all poles.

b. Re-treat the charge if more than 15 percent of the

borings are found to be nonconforming.

c. Re-treat all nonconforming poles found in the

penetration sampling.

d. Re-treated poles shall be 100 percent tested for

penetration boring. Poles which are still nonconforming

after the second re-treatment shall be permanently rejected.

Permanently rejected poles shall have their brands removed.

8.4.3.2 For poles with a circumference of 37.5 inches or more at

6 feet from the butt:
Bulletin 1728F-700

Page 15

a. Forty-five feet and shorter: Bore each pole and

re-treat only those found to be nonconforming unless more

than 15 percent fail, in which case the entire lot shall be

re-treated.

b. Fifty feet and longer: Bore each pole twice at

90 degrees apart approximately in the same plane around the

pole. Accept only those poles conforming to the penetration

requirement in both borings.

c. Nonconforming poles shall be re-treated and 100 percent

retested for penetration. Poles which are still

nonconforming after a second re-treatment shall be

permanently rejected. Permanently rejected poles shall have

their brands removed.

d. Penetration depth shall be measured along a boring from

the outer end toward the inner end for a distance throughout

which there is continuous preservative penetration, as

indicated by evidence of preservative in each annual ring

included.

e. When poles which have been deep incised or radial

drilled are bored for penetration and retention testing, the

borings shall be taken midway on a diagonal between an

incision or hole and an incision or hole in the next

vertical row above or below.

8.5 Re-treatment: Poles may be retreated only twice.

8.5.1 Creosote, Penta, and Copper Naphthenate: Total steaming

time, both for initial treatment and re-treatment, are cumulative

and shall not exceed the limits for steam found in paragraph

8.1.2.1.

Re-treatment of reserve treated stock poles shall be by

submersion in preservative for not less than 10 minutes under

25 pounds per square inch gauge pressure or not less than

30 minutes at atmospheric pressure.

8.5.2 Waterborne Preservatives: Poles which require retreatment shall be air dried sufficiently to accept re-treatment.

Re-treatment shall be within original treatment limitations. Retreated poles shall conform fully to all the requirements of this

specification; otherwise, they shall be permanently rejected.

Re-treated poles shall have a letter "R" die-stamped, hammerstamped or burnbranded in the sawed butt surface following the

charge number to indicate that the poles have been re-treated.

Material Requirements

1. SCOPE

The material in Appendix A is reprinted primarily from the

American National Standards Institute (ANSI) Standard 05.1-1987,

"American National Standard Specifications and Dimensions for

Wood Poles." This material is reprinted by permission from ANSI.

Copies of ANSI 05.1-1987 may be purchased from the American

National Standards Institute, 1430 Broadway, New York, New York

10018.

2. DEFINITIONS

The following definitions shall apply to the terms used in this

standard:

Air Seasoning: Drying by the use of air where the air

temperature is not more than 140°F either in the open or under

cover.

Boulton Drying: Drying by heating in nonaqueous solution under

vacuum.

Check: The lengthwise separation of the wood that usually

extends across the rings of annual growth and commonly results

from stresses set up in wood during seasoning.

Compression Wood: Abnormal wood formed on the lower side of

branches and inclined trunks of softwood trees. Compression wood

is identified by its relatively wide annual rings, usually

eccentric; relatively large amount of summerwood, sometimes more

than 50 percent of the width of the annual rings in which it

occurs; and its lack of demarcation between springwood and

summerwood in the same annual rings. Compression wood, compared

with normal wood, shrinks excessively lengthwise.

Cross Break: A separation of the wood cells across the grain.

Such breaks may be due to internal strains resulting from unequal

longitudinal shrinkage or to external forces.

Dead Streak: An area, devoid of bark, resulting from progressive

destruction of the growth cells of wood and bark at the edges of

the streak. On a pole, a dead streak is characterized by a

discolored weathered appearance and by lack of evidence of

overgrowth along the edges of the deadened surface.

Decay: The decomposition of wood substance by fungi.
Bulletin 1728F-700

Page 19

Decay, Advanced (or Typical): The older stage of decay in which

the destruction is readily recognized because the wood has become

punky, soft and spongy, stringy, ring-shaked, pitted, crumbly,

or, in poles not stored or rafted in water, is in a soggy

condition. Decided discoloration or bleaching of the rotted wood

is often apparent.

Decay, Incipient: The early stage of decay that has not

proceeded far enough to soften or otherwise perceptibly impair

the hardness of the wood. It is usually accompanied by a slight

discoloration or bleaching of the wood.

Decayed Knot: A knot containing decay. Two types of decayed

knot are recognized.

Type I - Knots containing soft or loose fibers (decay)

which may extend the full length of the knot into the

pole and which are associated with heart rot.

Type II - Knots containing soft or loose fibers (decay)

which are not associated with heart rot.

Face of Pole: The concave side of greatest curvature in poles

with sweep in one plane and one direction, or the side of

greatest curvature between groundline and top in poles having

reverse or double sweep.

Ground Line Section: That portion of a pole between 1 foot above

and 2 feet below the ground line, as defined in the pole

dimension tables (see Tables 3 through 9). (For purposes of

defining the ground line when incising or radial drilling, see

paragraphs 9.7.1 and 9.7.2.)

Hollow Heart: A void in the heartwood caused by decay or insect

attack.

Hollow Pith Center: A small hole at the pith center of the trunk

or of a knot caused by disintegration of the pith (small soft

core occurring in the structural center of a tree or branch).

Insect Damage: Damage resulting from the boring into the pole by

insects or insect larvae. Scoring or channeling of the pole

surface is not classed as insect damage.

Kiln Drying: Drying by the use of heated air in batch or

progressive-type kilns.

Knot Cluster: Two or more knots grouped together as a unit, the

fibers of the wood being deflected around the entire unit;

distinct from the group of single knots in which each is a unit.

A knot cluster shall be considered as a single knot.

Knot Diameter: The diameter of a knot on the surface of the pole

measured in a direction at right angles to the lengthwise axis of
Bulletin 1728F-700

Page 20

the pole. The sapwood as well as the heartwood portion of a knot

shall be included in the measurement.

NOTE: For a description of means for defining the limits of

knots, see American National Standard Definitions of Terms

Relating to Timber, ANSI/ASTM D9-87.

Lot: A quantity of poles of like size, conditioning, and

fabrication usually making up one treating charge.

Red Heart: A condition caused by a fungus, Fomes pini, that

occurs in the living tree. It is characterized in the early

stages of infection by a reddish or brownish color in the

heartwood; known as "firm red heart." Later the wood of the

living tree disintegrates (decays) in small, usually distinct,

areas that develop into whiteline pockets.

Sap Stain: A discoloration of the sapwood, caused by the action

of certain molds and fungi, that is not accompanied by softening

or other disintegration of the wood.

Scar: A depression in the surface of the pole resulting from a

wound where the living tree has not compartmentalized the wound

and reestablished the normal cross section of the pole.

Scar, Turpentine Acid Face: An area in the lower portion of a

southern pine pole where bark hack removal with acid applied has

caused resin to flow. No removal of sapwood has occurred.

Scar, Turpentine Cat Face: A depression in the surface of a

southern pine pole resulting from a wood hack into the sapwood,

where the tree has not compartmentalized the wound and

reestablished the normal cross section of the pole.

Shake: A separation along the grain, the greater part of which

occurs between the rings of annual growth.

Short Crook: A localized deviation from straightness which,

within any section 5 feet or less in length, is more than 1/2 the

mean diameter of the crooked section (see Fig. 1, Diagram 3).

Spiral-Grained (Twist-Grained) Wood: Wood in which the fibers

take a spiral course about the trunk of a tree instead of a

vertical course. The spiral may extend in a right-hand or lefthand direction around the tree trunk. Spiral grain is a form of

cross grain.

Split: A lengthwise separation of the wood extending completely

through the piece from one surface to another.

Steam Conditioning: Subjecting poles in a closed vessel to steam

prior to treatment.
Bulletin 1728F-700

Page 21

Sweep: Deviation of a pole from straightness (see Fig. 1,

Diagrams 1 and 2, Exhibit A).

3. POLE CLASSES

Poles meeting the requirements of this standard are grouped in

the classes identified in Tables 3 through 9, based on their

circumference measured 6 feet from the butt. Poles of a given

class and length are designed to have approximately the same load

carrying capacity regardless of species.

4. MATERIAL REQUIREMENTS: GENERAL

4.1. Species.

4.1.1 Poles: See Table 1, Appendix A.

4.1.2 Telephone Pedestal Stubs.

4.1.2.1 All round pedestal stubs shall conform to material

requirements for poles. Plywood peeler cores, and similar

material where the sapwood has been largely removed, are not

acceptable.

4.1.2.2 All sawn stubs shall conform to the following material

requirements:

All sawn stubs furnished under this specification shall be free

of brashy wood, cross breaks, decay, insect holes larger than

3/32 of an inch, and dried to a moisture content of not more

than 19 percent. The stubs shall be surfaced on four sides,

shall meet additional requirements as shown on specification

drawings, and shall be made of one of the following:

Douglas-fir conforming to provisions of No. 1 "Structural Joists

and Planking," as per paragraph 123b, of Rule 16 of the Standard

Grading Rules for West Coast Lumber (WCLIB Number 16-revised

1991). All references to Douglas-fir shall be that of coastal

origin.

Southern Yellow Pine conforming to the provision of No. 1

"Structural Joist and Planks" as per paragraph 312 of the 1991

Southern Pine Inspection Bureau (SPIB) Grading Rules except for

the applicable overriding provisions of the REA specification.

Other Species acceptable for pedestal stubs under this

specification, shall be equivalent in grade to those specified in

paragraph 4.1.2.2 of this section.
Bulletin 1728F-700

Page 22

4.2 Conditioning, Seasoning, and Treatment Limitations:

4.2.l Air Seasoning: Air seasoning shall be in conformance with

this specification for preservative treatment without developing

pretreatment decay. Presteaming or after steaming is permitted

for species in Treatment Group A. However, if such steaming is

employed, the maximum temperature shall not exceed 240°F. The

total steaming time from the time steam is introduced into the

cylinder, including both initial and final steam, shall not

exceed 4 hours duration (see exception for Douglas-fir (coast)

and western larch in paragraph 4.2.5). Up to 6 hours steam at

temperatures up to 240°F may be employed for ponderosa pine

poles, provided that when steaming commences the moisture content

(calibrated to the basis of oven dry weight moisture content)

measured with a resistance-type moisture meter with insulated

pins is not over 25 percent at 2.5 inches from the surface at

midlength. Otherwise, the maximum steaming time for ponderosa

pine poles is 4 hours.

All air seasoned poles shall be conditioned prior to or during

treatment so that the pith center of the pole shall have been

heated for at least 2 hours at a temperature of not less than

150°F. (Heat transfer usually requires 1 hour for each inch of

diameter at 150°F.)

Poles to be salt treated which have not been conditioned as

stated above shall be kiln dried prior to treatment. Kiln-dried

poles shall be treated within 1 month from the time they are

removed from the kiln.

Pedestal stubs which are air-seasoned shall have been dried by

natural air circulation. They shall be checked by the heartwood.

The moisture content shall not exceed 25 percent at a depth of

1 1/2 inches or at the sapwood heartwood line, whichever is less.

All sawn pedestal stubs shall be dried to a moisture content of

not more than 19 percent prior to treatment.

4.2.2 Boulton Drying Temperature: The temperature employed in

Boulton drying poles of species listed under Treatment Group B of

Table 1 shall not exceed 220°F. These poles may be steamed up to

240°F for a maximum time of 4 hours, but such steaming shall be

limited to steaming after treatment.

4.2.3 Kiln Drying: Where kiln drying is employed on southern

pine, ponderosa pine, red pine, jack pine, lodgepole pine,

Douglas-fir (coast), and western larch, the maximum dry bulb

temperature shall be increased gradually and shall not exceed

170°F (with the exception noted below). Where kiln drying is

employed on western red cedar, the maximum dry bulb temperature

shall be increased gradually and shall not exceed 160°F. In

compartment kilns operating at temperatures up to 170°F, the

maximum wet bulb depressions shall not exceed 50°F with the

exception that during the first 24 hours there is no limitation

on wet bulb depression. In progressive-type kilns operating at
Bulletin 1728F-700

Page 23

temperatures up to 170°F, the maximum wet bulb depression shall

not exceed 50°F in the body of the kiln and 90°F at the entrance

to the kiln.

Exception: Drying over 170°F is permitted for southern pine,

lodgepole pine, Douglas-fir (coast), and western larch species.

The maximum dry bulb temperature shall not exceed 230°F for these

species. For dry bulb temperatures over 200°F, the wet bulb

depression shall be not less than 50°F with the exception that

during the first 24 hours there is no limitation on wet bulb

depression.

4.2.4 Steam Conditioning: The steam temperature employed in

steam conditioning for poles of species in Treatment Group C of

Table 1 shall not exceed 245°F. The time duration for poles with

specified circumferences 37.5 inches or less at 6 feet from the

butt shall not exceed 17 hours. Poles with specified

circumferences larger than 37.5 inches at 6 feet from the butt

shall not exceed 20 hours.

4.2.5 Steaming (Douglas-fir (coast) and Western Larch):

Douglas-fir (coast) and western larch poles which are to be

treated with waterborne preservatives and which have not been

Boulton dried may be steamed at a maximum temperature of 240°F.

For poles in this category, the maximum duration starting with

the time steam is introduced into the cylinder, including both

initial and final steam, shall not exceed eight hours provided

each pole before steaming has a maximum moisture content not

exceeding 25 percent when measured with a resistance type

moisture meter with insulated pins at 2.0 inches from the surface

at mid-height.

4.3 Solvent Recovery: When poles of any species have been

treated with a system using an organic solvent-based preservative

solution, a solvent recovery cycle of not over 15 hours at a

maximum temperature of 225°F is permitted provided each pole

before treatment has a maximum moisture content of 25 percent

when measured with a resistance-type moisture meter (calibrated

to the basis of oven dry weight moisture content) with insulated

pins at 2 inches from the surface at mid-height.

4.4 Rate of Growth: The average rate of growth measured on the

sawed butt surface in the outer 2 inches of poles having a

circumference of 37.5 inches or less at 6 feet from the butt, and

in the outer 3 inches of poles having a circumference of more

than 37.5 inches at 6 feet from the butt, shall not be less than

six rings per inch. Exception: Poles with four and five rings

per inch are acceptable if 50 percent or more summerwood is

present.

As an alternative, the ring count and summerwood measurements

mentioned above may be made on an increment core taken at 6 feet

from the butt directly above the place where the average rate of

growth is indicated on the butt surface.
Bulletin 1728F-700

Page 24

5. MATERIAL REQUIREMENTS: PROHIBITED DEFECTS

5.1 Cross breaks (cracks).

5.2 Decay, except as permitted for firm red heart in 6.1,

defective butts in 7.4 and decayed knots in 7.6. When conditions

indicate on distribution poles and transmission poles (in the

white), a boring to the center of the pole shall be taken at

approximately 1 foot above the ground line, at midpoint, near

(within 2 inches) a check or at any other suspicious area. The

borings shall be examined by the quality control supervisor and

the inspector for any signs of decay.

Where a question of possible decay and infection remains, the

pole shall be further tested using techniques such as the

culturing or microscopic examination. Evidence of fungal

fruiting bodies and mycelium on or in a piece of wood shall be

considered as evidence of decay and the piece of wood shall be

permanently rejected as nonconforming.

5.3 Dead streaks, except as permitted in 7.3.

5.4 Holes, other than drilled holes provided for in the

specification, open or plugged, except holes for test purposes,

which shall be plugged with treated plugs.

5.5 Hollow butts or tops, except as permitted under hollow pith

centers and defective butts.

5.6 Marine borer damage.

5.7 Nails, spikes and other metal not specifically authorized by

the purchaser.

6. MATERIAL REQUIREMENTS: PERMITTED DEFECTS

6.l Firm Red Heart: Firm red heart not accompanied by softening

or other disintegration (decay) of the wood is permitted.

6.2 Hollow Pith Centers: Hollow pith centers in tops or butts

and in knots are permitted in poles that are to be given fulllength treatment.

6.3 Sap Stain: Sap stain that is not accompanied by softening

or other disintegration (decay) of the wood is permitted.

6.4 Scars: Turpentine acid face scars are permitted anywhere on

the pole surface.
Bulletin 1728F-700

Page 25

7. MATERIAL REQUIREMENTS: LIMITED DEFECTS

7.1 Bark Inclusions: Depressions containing bark inclusions

shall not be more than 2 inches in depth, measured from the

surface of the pole.

7.2 Compression Wood: The outer 1 inch of all poles shall be

free from compression wood visible on either end.

7.3 Dead Streaks: A single, sound dead streak is permitted in

western red cedar and northern white cedar, provided the greatest

width of the streak is less than 1/4 of the circumference of the

pole at the point of measurement.

7.4 Defective Butts: Hollowing in the butt caused by "splinter

pulling" in felling the tree is permitted, provided that the area

of such a hollow is less than 10 percent of the butt area.

Hollow heart or decay, or both, is permitted in cedar poles only,

provided the aggregate area of the hollow heart or decay, or

both, does not exceed 10 percent of the entire butt area and does

not occur closer than 2 inches to the side surface and provided

that the depth of the hollow does not exceed 2 feet, measured

from the butt surface.

7.5 Insect Damage: Insect damage, consisting of holes 1/16 inch

or less in diameter, or surface scoring or channeling is

permitted. All other forms of insect damage are prohibited,

except those associated with hollow heart in cedar poles.

7.6 Knot: The diameter of any single knot and the sum of knot

diameters in any 1-foot section shall not exceed the limits of

Table 2.

In determining the sum of knot diameters in any 1-foot section,

only those knots with diameters over 0.5 inch whose pitch centers

fall within the section shall be included in the sum, and the

1-foot section shall be located so as to include the maximum

number of knots, i.e., the most severe condition. Type II

"decayed knots" are permitted.

NOTE: See section 3 and Tables 3 through 9 for pole classes.

7.7 Scars (Cat Face): A scar is the result of injury to the

living tree which has begun to compartmentalize and contain the

injury. This provision does not refer to damage done to the tree

(pole) after it has been cut. No pole shall have a scar or

turpentine cat face (southern pine) located within 2 feet of the

ground line. Turpentine scars need be trimmed only to the extent

necessary for examination for evidence of fungus infection and

insect damage. Other sound scars are permitted elsewhere on the

pole surface, provided they are smoothly trimmed and do not

interfere with the cutting of any gain and provided that:

(1) The circumference at any point on trimmed surfaces

located between the butt and 2 feet below the ground line is

not less than the minimum circumference specified at 6 feet

from the butt for the class and length of the pole; and

(2) The depth of the trimmed scar is not more than 2

inches, if the diameter is 10 inches or less, or 1/5 the

pole diameter at the location of the scar if the diameter is

more than 10 inches.
Bulletin 1728F-700

Page 27

7.8 Shakes: Shakes in the butt surface which are not closer

than 2 inches to the side surface of the pole are permitted,

provided they do not extend to the ground line. Shakes or a

combination of connected shakes which are closer than 2 inches to

the side surface of the pole are permitted, provided they do not

extend further than 2 feet from the butt surface and do not have

an opening wider than 1/8 inch. Shakes in the top surface are

permitted in poles that are to be given full-length preservative

treatment, provided that the diameter of the shake is not greater

than 1/2 the diameter of the top of the pole and is not closer

than 2 inches from the surface.

7.9 Shape: Poles shall be free from short crooks. A pole may

have sweep subject to the following limitations:

(1) Where sweep is in one plane and one direction only:

(a) For poles 50 feet and shorter of all species

except northern white cedar, a straight line joining

the surface of the pole at the ground line and the edge

of the pole at the top shall not be distant from the

surface of the pole at any point by more than 1 inch

for each 10 feet of length between these points in

90 percent or more of an inspection lot. In the

remainder of the inspection lot (10 percent), the poles

may have a deviation of one inch for each 6 feet of

length when measured as above.

(b) Poles 55 feet and longer shall meet the

1-inch-in-10-feet requirement in 75 percent or

more of an inspection lot. In the remainder of the lot

(25 percent), the poles may have a deviation of 1 inch

for each 6 feet of length when measured as above. The

deviation for all northern white cedar poles in an

inspection lot shall not be more than 1 inch for each

4 feet of length as measured above (see figure 1,

diagram 1).

(2) Where sweep is in two planes (double sweep), except in

northern white cedar poles, or in two directions in one

plane (reverse sweep), a straight line connecting the

midpoint at the ground line with the midpoint at the top

shall not at any intermediate point pass through the surface

of the pole (see figure 1, diagram 2). The double sweep

limitation for northern white cedar poles shall be as

follows: Where sweep is in two planes (double sweep), the

sum of the sweeps in the two planes (each sweep being

measured as shown in figure 1, diagram 1) shall not be

greater than the allowance for sweep in one plane and one

direction for a pole of the same length.
Bulletin 1728F-700

Page 28

7.10 Spiral Grain: Spiral grain (twist grain) is permitted as

follows:

 Length Maximum Twist of

 of Pole (Feet) Grain Permitted

 30 and shorter 1 complete twist in any 10 ft.

 35-45, inclusive 1 complete twist in any 16 ft.

 50 and longer 1 complete twist in any 20 ft.

7.11 Splits and Checks.

7.11.1 In the Top: A split or a combination of two single

checks (each check terminating at the pith center and separated

by not less than 1/6 of the circumference) having one or both

portions located in a vertical plane within 30 degrees of the top

bolt hole shall not extend downward along the pole more than

6 inches. All other combinations of checks or a split shall not

extend downward along the pole more than 12 inches. (Two checks

of approximately the same width, each check terminating at the

pith center and separated by 1/2 inch or less of wood fiber at

any point on the pole circumference, shall be considered as a

single continuous check.)

7.11.2 In the Butt: A split or a combination of two single

checks, as defined in 7.11.1, in its entirety, shall not extend

upward along the pole more than 2 feet.

8. DIMENSIONS

For dimensions of particular species of poles, see Tables 3

through 9, Exhibits B to G. For dimensions of stubs and anchor

logs, see Tables 11, 12, and 13 respectively, Exhibits I and J.

8.1 Length: Poles less than 50 feet in length shall not be more

than 3 inches shorter or 6 inches longer than nominal length.

Poles 50 feet or more in length shall not be more than 6 inches

shorter or 12 inches longer than nominal length.

Length shall be measured between the extreme ends of the pole.

8.2 Circumference: The minimum circumferences at 6 feet from

the butt and at the top, for each length and class of pole, are

listed in Tables 3 through 9. The circumference at 6 feet from

the butt of a pole shall not be more than 7 inches or 20 percent

larger than specified minimum, whichever is greater.

The top dimensional requirement shall apply at a point

corresponding to the minimum length permitted for the pole.

8.3 Classification: The true circumference class shall be

determined as follows: Measure the circumference at 6 feet from

the butt. This dimension shall determine the true class of the

pole, provided that its top (measured at the minimum length

point) is large enough. Otherwise, the circumference at the top
Bulletin 1728F-700

Page 29

shall determine the true class, provided that the circumference

at 6 feet from the butt does not exceed the specified minimum by

more than 7 inches or 20 percent, whichever is greater.

9. MANUFACTURING REQUIREMENTS

9.1 Bark Removal: Outer bark shall be completely removed from

all poles.

On all poles, no patch of inner bark more than 1 inch wide shall

be left on the pole surface between the butt and 2 feet below the

ground line.

On poles that are to be given full-length treatment, no patch of

inner bark larger than 1 inch wide and 6 inches long shall be

left on the pole surface between the top and 2 feet (below the

ground line.

NOTE: These provisions are intended to allow an

occasional patch of bark and shall not be interpreted to

allow numerous patches of bark.

9.2 Sawing: All poles shall be neatly sawed at the top and at

the butt along a plane which shall not be out of square with the

axis of the pole by more than 2 inches per foot of diameter of

the sawed surface. Beveling at the edge of the sawed butt

surface not more than 1/12 the butt diameter in width, or an

equivalent area unsymmetrically located, is permitted. The sawed

surface shall be smooth enough to allow the inspector's mark to

be clear and legible after treatment.

9.3 Trimming: Completely overgrown knots, rising more than 1

inch above the pole surface, branch stubs, and partially

overgrown knots shall be closely trimmed. Completely overgrown

knots less than 1 inch high need not be trimmed. Trimming may be

done by shaving machine or by hand.

9.4 Shaving: If shaving is used, the depth of cut shall not be

more than necessary to remove inner bark and to trim smoothly and

closely all branch stubs and overgrown knots. There shall be no

abrupt change in the contour of the pole surface between the

ground line and the aboveground sections. The lower 2 feet of

poles may be trimmed to remove wood fibers causing butt flare,

provided sufficient sapwood remains to obtain customer's minimum

penetration requirement.

9.5 Marking and Code Letters: The information in items (1)

through (5) below shall be burnbranded legibly and permanently on

the pole face or included on a metal tag affixed thereto. The

metal tag for the face of the pole shall be round, noncorrosive,

tight-fitting and recessed 1/4 inch. It shall be fastened with a

barbed or serrated noncorrosive nail. The information in items

(5) and (6) below shall be placed on the sawed butt surface. If
Bulletin 1728F-700

Page 30

so desired by the producer or the purchaser, items (1), (3), and

(4) below may also be placed on the sawed butt surface.

(1) The supplier's code or trademark.

(2) Insured warranty or quality assurance mark, if

applicable.

(3) Plant location and month and year of treatment.

(4) Code letters denoting the pole species, preservative,

and required retention.

(5) The true circumference-class numeral and numerals

showing the length of the pole.

(6) The charge number. (An "R" shall also be die-stamped,

hammer-stamped or burnbranded in the sawed butt surface of

re-treated poles.)

The code letters, not less than 5/8-inch high if

burnbranded, and not less than 1/8-inch high if on a metal

tag, designating the pole species and preservative used,

shall be as follows:

treatment, provided that the cut surfaces are subsequently

pressure treated or treated with a supplemental groundline type

preservative.
Bulletin 1728F-700

Page 32

9.6.3 All framing shall be in accordance with the attached

drawings or with the drawings which accompany the order. Anchor

logs shall be bored as required by the order for them.

9.6.4 When gains are required on one side only, they shall be

cut on the face of the pole, and the gained surfaces shall be in

approximately parallel planes. Transmission poles (e.g., poles

50 feet or longer) may be treated undrilled.

9.6.5 Transmission poles may be bored before treatment for

fumigation if designated in the purchase order.

9.6.6 Bolt holes in poles treated with waterborne preservatives

shall be drilled to the maximum dimension permitted by the REA

standard drawings (i.e., 1/16 inch over the nominal size).

9.6.7 Anchor logs shall be bored as required by the order for

them.

9.7 Incising.

9.7.1 Distribution Poles: Western red cedar and northern white

cedar distribution poles to be treated by the thermal process

shall be ground line incised in the area 2 feet above and 4 feet

below the designated ground line with a pattern and depth

sufficient to insure uniform penetration of the total sapwood in

the incised area.

9.7.2 Transmission Poles: Western red cedar and northern white

cedar transmission poles to be treated by the thermal process

shall be ground line incised in the area 2 feet above and 4 feet

below the designated ground line, with a pattern and depth

sufficient to insure uniform penetration of the total sapwood in

the incised area. All Douglas-fir (coast) transmission poles

(poles 50 feet or longer) shall be deep-incised or radial drilled

to a minimum depth of 2 1/2 inches in the area 2 feet above and

4 feet below the designated ground line. When indicated by

experience, a deeper penetration may be specified by the

purchaser as shown in the table below:

 50 thru 65 feet 4.0 inches

 70 thru 85 feet 4.5 inches

 90 feet or longer 5.0 inches

Deep incising or radial drilling shall be, as minimum

spacing, a 3x6-inch vertical diamond pattern. Radialdrilled holes shall not exceed 5/16 inch in diameter.
Bulletin 1728F-700

Page 33

9.7.3 Incising or Drilling: Incising or drilling shall be

cleanly done to prevent tearing or excessive shattering of

fibers. Incisions shall be along (in line with) the axis of the

pole.

9.7.4 Pedestal Stubs: Western red cedar, northern white cedar

and western larch that are to be treated by thermal process shall

be incised in the groundline section in accordance with AWPA

Standard C8. The lengthwise surface of sawn Douglas-fir stubs

shall be incised. The incisions shall be approximately 0.4 inch

deep, clean-cut and the pattern shall insure uniform penetration

of preservative.

10. STORAGE AND HANDLING

10.1 Storage: When it is necessary to hold poles in storage,

they shall be stacked on treated or other nondecaying skids,

stickers, etc., of such dimensions, and so arranged, as to

support the poles without producing noticeable distortion of any

of them. The height of the poles shall be limited to avoid

damage to poles on the bottom layers. All wood skids, stickers,

etc., shall be treated.

Poles shall be piled and supported in such a manner that all

poles are, at any point, at least 1 foot above the general ground

level and any vegetation growing thereon. Stacks of poles shall

not be allowed to settle at any point to less than 1 foot above

the ground or any adjacent vegetation growing thereon. No

decayed or decaying wood shall be permitted to remain underneath

stored poles or in the yard area adjacent to the stored poles.

Unseasoned poles shall not be dead piled at any time for air

seasoning. This restriction does not apply to short-term piling

associated with normal manufacturing procedures. Where special

conditions exist, such as in arid areas, a waiver to this dead

piling restriction may be requested from REA.

10.2 Handling: Poles shall not be dragged along the ground.

Cant hooks, pole thongs, or other pointed tools shall not be

applied to the ground line section of any pole.

10.3 Mechanical Damage: Poles are not acceptable if they

contain indentations attributed to loading or handling slings

that are 1/4 inch or more deep over 20 percent or more of the

pole circumference, or more than 1/2 inch deep at any point.

Other indentations or abrasions, for example, forklift damage,

chain-saw damage, etc., shall not be more than 1/10 the pole

diameter at the point of damage up to a maximum of 1 inch. Such

damage is permitted in an oversized section, where the excess of

wood shall be taken into consideration in evaluating the effects

of the damage. In any case, the remaining circumference shall

meet or exceed the specification minimum.

Note B - Test By Toluene Extraction

Note C - This retention for lime ignition or x-ray spectroscopy method. Copper pyridine method, which equals 90% of lime ignition results, is required

when poles may have been in contact with salt water, and for all species native to the Pacific Region, unless it specifically states on the raw

material invoice that the material has not been in contact with salt water or shown by analysis that there are no additional chlorides present in the

wood before treating.

Note D - Pressure Treatment Only

 Note - In Decay Zone 5, shown in REA Bulletin 161-4, minimum retentions are .130 PCF for Southern Pine and .150 PCF for Douglas-fir, for all poles

within 50 miles of coastal waters.

* Minimum pounds/cubic foot (pcf) acceptable at time of shipment to user.

A Reduction of 10 percent from the values shown above in any of the test zones will be acceptable at destination within 30 days from the date of delivery.

In the event of rejection of any poles at destination, REA and the producers shall be promptly notified. The producer may examine the poles at destination

within 2 weeks of notification.
