Dear Colleague:

The past year (1991) marked the 90th Anniversary of the National Institute of Standards and Technology (NIST) formerly the National Bureau of Standards (NBS). As with other anniversaries, this

is an opportunity to review the past and to plan and chart new directions for the future.

At the 50th Anniversary of NBS, Dr. Vannevar Bush asked, "Should an agency that is committed to the duty of setting standards also do research?" In my opinion the answer to his question is very

clear. Those who set scientific standards cannot limit themselves only to the application of science

but must constantly seek to improve the state of the art of the measurement process that can only

be achieved through a concomitant effort of applied and basic research. Within this precept lie the

uniqueness and strengths of NIST Standard Reference Materials (SRMs).

This catalog contains standards that were developed by scientists at NIST to aid and support industry, government, and science. Many of the SRMs were certified in cooperation with industry, others were certified using technology and scientific research based here at NIST. SRMs offered in this catalog can assure measurement compatibility and, in many cases, connect the measurement process

to the "National Measurement System."

The number and type of SRMs described in the catalog have increased to over 1,200 since our previous issue. The catalog contains a guide and two revised indexes, each of which groups the SRMs

and RMs according to a distinctive characteristic or descriptor. Please read the section entitled

"How to Use This Catalog" as a starting point in examining NIST's available SRMs.

Many of you have informed us by letter or personally at exhibits of the need for new SRMs. We

hope that some of the new SRMs recently developed at NIST will meet your standards needs. We

have endeavored to provide at least some modest growth in our certification activities to accommodate your many requests. If you have a requirement that we currently do not meet, please contact

us. There is a section in this catalog entitled "Guide for Requesting Development of Standard Ref- erence Materials," that will facilitate processing your requests.

We appreciate your continued support for the SRM program and look forward to being able to serve you in the coming year.

Sincerely,

William P. Reed

Abstract and Key Words

This catalog provides technical and general ordering information for the Standard Reference Materials

(SRMs) and Reference Materials (RMs) currently available from the National Institute of Standards and

Technology (NIST) Standard Reference Materials Program (SRMP). The materials are arranged according

to technical category and classified as follows: Standard Reference Materials for Chemical Composition;

Standard Reference Materials for Physical Properties; and Standard Reference Materials for Engineering

Materials. Technical descriptions are given for all materials and may include certified values. However,

these values may be incomplete as they appear in the catalog and therefore cannot be referenced for actual

measurement purposes. The certificates issued by SRMP are the only legitimate sources of certified information for NIST reference materials.

Key Words: analysis, calibration, Certified Reference Materials, characterization, composition, concentration, material, measurement, property, quality assurance, quality control, Reference Materials, Standard

Reference Materials, standardization.

NIST Policy Regarding Use of Metric (SI) Units

In February 1991, the Director of NIST established the following policy:

"In accordance with the Metric Conversion Act of 1975 as amended by Section

5164 of the Omnibus Trade and Competitiveness Act of 1988 and as required by

related provisions of the Code of Federal Regulations, the National Institute of

Standards and Technology (NIST) will use the modem metric system of measurement

units (International System of Units; abbreviation: SI) in all publications. When the

field of application or the special needs of users of NIST publications require the use of non-SI units, the values of quantities will be first stated in SI units and the

corresponding values expressed in non-SI units will follow in parentheses."

This policy is part of the NIST Metric Transition Plan, developed in response to the legislation which

mandates adoption of the SI system of units by all Federal agencies as the preferred system of weights and

measures for United States trade and commerce. Governmental commitment to metrication has been

further reinforced with the signing of Executive Order 12770 on July 25, 1991, by the President of the

United States, which requires each Federal Agency to adopt use of the metric (SI) system into all its business-related activities by September 30, 1992.

The technical information contained in this catalog is consistent with the above-stated NIST policy. Only

SI units and symbols have been used to describe the reference materials contained herein. Therefore,

abrogated or obsolete quantifiers (i.e., the term, ppm), no longer appear, but rather have been replaced

with the correct SI term, (mg/kg), and reference material values previously expressed in only inch-pound

units, have been converted to the appropriate SI units. [1,2] Due to space limitations, the non-SI units converted are not shown in the catalog. The user should consult those SRM and RM certificates where data

have been expressed in both SI and non-SI units. Lastly, in cases where SI unit conversions are not involved, terms in widest current usage (i.e., Wt. %), have been adopted and applied consistently throughout

the catalog.

How to Use This Catalog

The NIST Standard Reference Materials Catalog 1992-93 lists Standard Reference Materials (SRMs) and

Reference Materials (RMs) issued by the NIST Standard Reference Materials Program. It consists of a guide and two (2) indexes, each of which groups the SRMs and RMs according to a distinctive characteristic or descriptor. Selection of the guide or one index over another to locate the information desired will

depend on the user's prior knowledge of a specific SRM or RM and intended SRM or RM application.

Guide to SRM/RM Technical Categories - This is a general listing based on the three major categories into

which all the SRMs and RMs have been assigned. The categories are divided into sequentially numbered

sections, each of which describes a material class or technical property class. The sections are further divided into subsections, each of which describes a specific type of material or technical property and the

physical form(s) of the SRMs and RMs contained therein. The titles of the subsections are the descriptors

for the tables comprising the catalog.

SRM/RM Subject Index - This index is based on short word descriptors (one to four words) of the SRMs

and RMs in the catalog. These descriptors may identify a section, subsection, a material class, a specific

SRM property, a specific SRM application, or a measurement technique. Some descriptors may coincidently

also identify an individual SRM or RM; however, only a few SRMs or RMs will be so described. The index

is arranged in alphabetical order of the first word of the descriptor. Because of the variety of descriptors used,

some SRM and RM materials may be cross-referenced.

SRM/RM Numerical and Certificate Index -This index is based on the unique numerical identifier as- signed to each and every SRM and RM issued by NIST. This identifier is the SRM or RM Number, an integral part of the reference material name which appears on each SRM certificate or RM report of

investigation. The index lists all the SRMs and RMs sequentially by this number, beginning with SRM lc

and ending with RM 9529. A short word descriptor of the SRM or RM, the category subsection in which

it is assigned, and the certificate or report-of-investigation date of issue is also provided for reference.

HOW TO LOCATE SPECIFIC INFORMATION

About an unknown SRM or RM material needed for a particular technical application -

Refer to the Guide to SRM/RM Technical Categories, select the most appropriate of the three categories,

review all the sections and subsections therein and note the page numbers.

About a material from a specific class of materials and of known technical application -

Refer to the SRM/RM Subject Index, check for alternative descriptors and cross-references, and note

page numbers.

About a material whose SRM or RM number is known -

Refer to the SRM/RM Numerical and Certificate Index and note the page number.

Program Information

The National Institute of Standards and Technology (NIST) offers for sale over 1,000 different materials

through its Standard Reference Materials Program (SRMP). These materials are primarily Standard

Reference Materials (SRMs) certified for their chemical compositions, chemical properties, or physical

properties, but also include other reference materials. All materials bear distinguishing names and

numbers by which they are permanently identified. Thus, each material bearing a given description is identical (within the specified limits) to every other sample bearing the same designation— with the

exception of individually certified items, which are further identified by serial number.

Definitions

From "Terms and definitions used in connection with reference materials," ISO Guide 30-1981 (E):

1. "Reference Material (RM): A material or substance, one or more properties of which are

sufficiently well established to be used for the calibration of an apparatus, the assessment of a measure- ment method, or for assigning values to materials."

2. "Certified Reference Material (CRM): A reference material, one or more of whose property

values are certified by a technically valid procedure, accompanied by or traceable to a certificate or other

documentation which is issued by a certifying body."

NIST Standard Reference Materials (SRMs): Certified reference materials issued by NIST. These are

well-characterized materials produced in quantity to improve measurement science. SRMs are certified for

specific chemical or physical properties, and are issued by NIST with certificates that report the

results of the characterization and indicate the intended use of the material. They are prepared and used

for three main purposes:

(1) To help develop accurate methods of analysis (reference methods);

(2) To calibrate measurement systems used to: (a) facilitate exchange of goods,

(b) institute quality control,

(c) determine performance characteristics, or

(d) measure a property at the state-of-the-art limit; and

(3) To assure the long-term adequacy and integrity of measurement quality assurance programs.

NIST certified values are obtained by one of three routes of measurement:

(1) A previously validated reference method,

(2) Two or more independent, reliable measurement methods, or

(3) A network of cooperating laboratories, technically competent and thoroughly knowledgeable with

the material being tested.

These measurement routes are described in "The Role of Standard Reference Materials in

Measurement Systems," NBS Monograph 148, 54 pages (Jan. 1975).

Reference Materials (RMs) listed in this catalog are sold, but not certified, by NIST. They meet the ISO

definition for RMs, and many meet the definition for CRMs. The documentation issued with these materials is either a:

(1) "Report of Investigation," the sole authority being the author of the report. RMs are intended to

further scientific or technical research on particular materials. The principal consideration in issuing RMs

is to provide a homogeneous material so that investigators in different laboratories are assured that they

are investigating the same material.

(2) "Certificate," issued by the certifying agency (other than NIST), e.g., other national laboratories,

other government agencies, other standardizing bodies, or other non-profit organizations. When deemed to

be in the public interest and when alternate means of national distribution do not exist, NIST acts as the

distributor for such materials. This service is available to organizations that qualify and have the reference

materials that would help meet national measurement needs.

SRM Catalog

New catalogs of NIST Standard Reference Materials (SRMs) are published approximately every 2 years,

listing materials available and renewal materials in preparation, and deleting discontinued materials. The

Catalog is supplemented by Price Lists issued simultaneously with each new catalog and approximately

every 6 months to keep the catalog current between editions. These supplements list current prices, and

reflect any changes in material availability— listing new and renewal materials and deleting discontinued

ones.A guide and two indexes are provided for user convenience. They are described in the section, How

to Use This Catalog.

Preparation and Availability of Standard Reference Materials

New and renewal Standard Reference Materials (SRMs) are being prepared continually. While these

SRMs are included in the next edition of the catalog and its supplements, prospective users whose names

are on the SRM mailing list are notified as soon as the new items become available. Requests for

placement on the SRM mailing list can be submitted at any time to SRMP.

Renewal SRMs are intended to be completed before the supply of an existing SRM is exhausted.

However, this is not always possible and an SRM may be out of stock for a time. When this occurs, those

ordering the material are so notified and possible substitute SRMs are suggested. When a renewal is issued, customers who have ordered the previous lot are promptly notified of the price and availability of

the renewal. If little demand exists or if an alternate source of supply becomes available, production of an SRM may be discontinued permanently.

Renewal SRMs may not be identical to the preceding lot; however, they meet the same specifications

and can be used for the same purpose. For example, the first 0.1% carbon Bessemer steel was prepared

in 1909 (Standard Sample No. 8). Since then a number of renewals, 8a, 8b, 8c, etc., have been prepared.

The current SRM 8j, 0.1% C, represents the eleventh lot of the material. Each lot differs somewhat in

detailed analysis; thus the use of the specific certificate for that lot is essential.

Guide for Requesting Development of Standard Reference Materials

The National Institute of Standards and Technology has the responsibility to develop, produce, and

distribute Standard Reference Materials (SRMs) that provide a basis for comparison of measurements on

materials, and that aid in the control of production processes. To carry out this function, the Standard

Reference Materials Program (SRMP) evaluates the requirements of science, industry, and government for

well-characterized reference materials, and directs the production and distribution of such materials.

NIST currently has over 1,000 SRMs available, about 100 new ones in preparation, and requests for

the production of many others.

To become an SRM, a candidate material must meet one or more of these criteria:

1. It would permit users to attain more accurate measurements.

2. Its production elsewhere would not be economically or technically feasible.

3. It would be an industry-wide standard for commerce from a neutral source not otherwise available

to the public.

4. Its production by NIST would assure continued availability of a well-characterized material

important to science, industry, or government.

NIST has recognized and responded to requests to enlarge the scope of the SRM program to include

all types of well-characterized materials for use in calibrating measurement systems, or for producing

scientific data that can be referred to a common base. However, the requests for new SRMs greatly

exceed the Institute's capacity to produce and certify such materials. Consequently, requests for new

SRMs of limited need or use are deferred in favor of requests that clearly show a critical need. To

determine which requests receive priority, NIST seeks and uses information supplied by industry and such

organizations as the American National Standards Institute (ANSI), American Nuclear Society (ANS),

American Petroleum Institute (API), American Society for Testing and Materials (ASTM), etc., to objectively assess the urgency and importance of proposed new reference materials.

6
Requests to SRMP for the development of a new SRM should provide the following information:

1. Short title of the proposed SRM.

2. Purpose for which the SRM would be used.

3. Reasons why the SRM is needed.

4. Technical characteristics and requirements for the material. Include additional requirements and

reasons if more than one SRM is necessary for standardization in this area.

5. Estimates of the probable present and future (6-10 years) demand for such an SRM, nationally

and internationally.

6. Justification for SRM preparation by NIST, particularly if a similar one could be produced or obtained from another source.

7. Pertinent information to aid justification for the SRM, such as: (a) an estimate of the potential

range of application, monetary significance of the measurement affected, scientific and technological

significance including, when feasible, estimates of the impact upon industrial productivity, growth, quality assurance or control, and (b) supporting letters from industry leaders, trade organizations, interested

standards committees, and others.

FTS: 879-OSRM [6776]

Fax number: (301) 948-3730

Telex: TRT 197674NIST UT

Each order should give the number of units, catalog number(s), and name(s) of the material(s) requested.

For example: "1 each, SRM 79a, Fluorspar (Customs Grade)." The materials described in this catalog are

sold only in the units listed or multiples thereof.

Acceptance of an order does not imply acceptance of any provisions set forth in the order contrary to the policy, practice, or regulations of the National Institute of Standards and Technology or the U.S.

Government.

In general, orders received for "out-of-stock" material will be filled with the renewal material, if available; otherwise they will be canceled. Customers are notified when an order is canceled and their

names are placed on a notification list. This list is used when a renewal material is issued to notify

customers of the price and availability of the item. Customers so notified are requested to submit a new

order if they still want the item.

For some individually certified SRMs, production lots are small and may entail frequent stock

outages. In these cases, the notification list is used to fill orders on a "first come, first served" basis.

For such SRMs, customers are notified that the SRM is again available and are requested to confirm

their original purchase orders.

Terms

Prices quoted are in U.S. dollars ($), and are published in the catalog supplements (price lists). When

price lists are issued, they are sent to persons or organizations on the SRM mailing list. These prices are

subject to change without notice and orders will be billed for the prices in effect at the time of shipment.

Discounts are given on individual purchases of 50 or more units of SRMs, or combinations thereof.

Remittances of the purchase price need not accompany the purchase order. Payment of invoices is expected within 30 days of the receipt of the invoice. Payment on domestic or foreign orders may be

made by any of the following:

a. Banker's draft against U.S.A. bank,

b. Bank to bank transfer to U.S.A. bank,

c. Cash against documents,

d. VISA or Mastercard only,

e. International money order, or

f. UNESCO coupons.

8
Letters of credit: If a letter of credit or any method of payment other than those listed above is to be

used, the services of an agent in the United States must be secured to act in the customer's behalf. The

agent must purchase the material and the NIST invoice will indicate that the agent is the purchaser. The

material is then shipped to the agent, who tranships in accordance with customer instructions.

NOTE: A customer identification number, i.e., social security number (SSN) for consumer customers; tax

identification number (TIN) for commercial customers; or agency location code (ALC) for government

customers, is required with each order.

Late Charges

Payment is due within 30 days of shipment of the order to the customer unless otherwise notified by

NIST. U.S. Treasury regulations require that late charges be assessed for each 30-day period, or portion

thereof, that the payment is overdue.

Proforma Invoice (Price Quotation)

Proforma service will be provided only upon request for such service.

Domestic Shipments

Shipments of material (except for certain restricted categories and refrigerated items) intended for the

United States and Canada are normally shipped prepaid, provided the parcel does not exceed the weight

limitations prescribed by postal laws and regulations. Refrigerated items are shipped prepaid air express

with shipping costs added to the invoice. Hazardous shipments will have an additional handling charge

added to the invoice.

Foreign Shipments

The regulations of various nations covering the importation of SRMs differ widely; any attempt to list all possible variations would be impractical. Therefore, where the shipping practices described as follows do

not apply, customers will be informed of the best method of shipment for their countries.

Shipping Practices: Most foreign orders are shipped by prepaid International Air Parcel Post.

Exceptions are those items in restricted categories, those items requiring refrigeration, and shipments

exceeding parcel post weight limits. The exceptions are shipped FOB Gaithersburg, MD, unless an agent

(shipping or brokerage firm) located in the United States is used or required. In this case, the customer

is notified, requested to obtain the services of an agent and inform NIST of the agent's name and

address. The material is then packed for overseas shipment and forwarded to the agent FOB

Gaithersburg, MD.

Documentation

The documents NIST furnishes are:

a. Two (2) commercial invoices,

b. One (1) packing slip, and

c. One (1) air waybill for air shipments.

All documents are printed in English.

If documents other than those listed above are required, the services of an agent in the United States

must be used to purchase and ship the material.

NOTE: Orders and inquiries submitted in English will be processed more rapidly than those requiring

translation.

Biomass Materials (powder form)

These Reference Materials, RMs 8491 Sugar Cane Bagasse (Saccharum spp. hybrid), 8492 Eastern Cottonwood {P. deltoides), 8493 Pinus Radiata, and 8494 Wheat Straw (Triticum aestivum) are intended primarily

for use in fundamental studies on the chemical and physical properties of cellulose, hemi-cellulose and

lignin and of their effects on various conversion processes. As part of the International Energy Agency

(IEA) Voluntary Standards Activity Group's work, these materials were selected initially for use as research

materials for a world-wide round robin analytical laboratory comparison using the Uppsala Method. They

were supplied by various institutions and were prepared, packaged and are being distributed by NIST.

At this time, no extensive property measurements have been made on these materials beyond ensuring

that the materials are homogeneous. A round robin is in progress with participation by international

laboratories and as results become available, the Report of Investigation that accompanies each of these

materials will be revised to reflect those changes.

All of the ground and homogenized materials were irradiated with Cobalt-60. The irradiation was

required to meet customs regulations for shipment of biomass materials to international destinations.

Rubbers and Rubber Compounding Materials

These SRMs have been prepared to provide the rubber industry with standard materials for rubber

compounding. They are useful for the testing of rubber and rubber compounding materials in connection with

quality control of raw materials and for the standardization of rubber testing.

Each material has been statistically evaluated for uniformity by mixing rubber and rubber compounds, vulcanizing them in accordance with ASTM Designation D-3182 and determining the stress-strain properties of

the resulting vulcanizates. Certificates are issued for the rubber SRMs 386j and 388p, because the properties

of different lots are not the same. Replacement lots of rubber compounding SRMs 371h, 372i, and 383a, impart

essentially the same characteristics to rubber vulcanizates so that certificates are not issued for these SRMs.

204. Optical Properties

Molecular Absorption and Molecular Luminescence (filter, solid, and solution forms)

The optical SRMs for spectrophotometry are certified transfer standards that fall into three (3) general

categories — transmittance, wavelength, and stray radiant energy— each of which addresses a specific instrumental parameter of an ultraviolet/visible absorption spectrometer that must be in control for

accurate optical transmittance measurements. To obtain optimum verification results, each SRM must be

used within the specified range of conditions for which it is intended.

SRM 930d: This SRM is for the verification and calibration of the transmittance and absorbance scales

of visible absorption spectrometers. It consists of three (3) individual Schott NG-type glass filters in separate metal cuvette-style holders and an empty filter holder. The nominal percent transmittances of the

three filters are 10, 20, and 30%T. The three filters are individually certified for transmittance at five (5)

wavelengths in the visible spectrum: 440.0, 465.0, 546.1, 590.0, and 635.0 nm. The optical transmittance

neutrality of SRM 930d is sufficient for the filters to be used to accurately verify absorption spectrometers

with maximum spectral bandpasses ranging from 2.2 to 6.5 nm for the five wavelengths at which the transmittances are certified. When SRM 930d is used in combination with SRM 1930, a 6-point stepwise verification of the transmittance scale is possible over the transmittance range from 1 to 50%T. A detailed

discussion of this SRM and SRM 1930 are given in Special Publication 260-116 which accompanies each

unit.

SRM 931e: This SRM is for the verification and calibration of the absorbance scales of ultraviolet and

visible absorption spectrometers having narrow spectral bandpasses. SRM 931e consists of three (3) sets of

four (4) solutions in sealed 10-mL ampules. The four solutions include a blank solution and three concentrations of an empirical inorganic solution prepared from high-purity cobalt and nickel metals dissolved in a mixture of nitric and perchloric acids. The user must transfer the blank and standard solutions to cuvettes of known pathlength. The spectrum has absorption maxima at 302, 395, and 512 nm, and a plateau

in the region of 678 nm at which the absorbances are certified. The nominal absorbances of the three empirical inorganic solution standards are 0.3, 0.6 and 0.9, respectively, at wavelengths 302, 395, and 512 nm. At wavelength 678 nm, the nominal absorbances of the three solutions are 0.1, 0.2, and 0.3, respectively.

The liquid filters may be used to verify absorption spectrometers with maximum spectral bandpasses ranging from 1.5 to 8.5 nm for the four wavelengths at which the absorbances are certified.

SRM 935a: This SRM is for the verification and calibration of the absorbance scales of ultraviolet

absorption spectrometers having spectral bandpasses not exceeding 2 nm. Issued in 15-g units, SRM 935a

consists of crystalline potassium dichromate of established purity. Solutions of ten (10) known concentrations of this SRM in 0.001 N perchloric acid (between 20 and 200 mg/kg) are certified for their specific

absorbances under well-defined conditions. The user must prepare the liquid solutions from SRM 935a

and then transfer them to cuvettes of known pathlength. The certified specific absorbances for the solutions prepared may be converted to their corresponding reference absorbance values using Beer's Law.

Acidic SRM 935a solutions may be prepared anywhere within the concentration range of 20 to 200 mg/kg

to provide a standard with the desired absorbance at a specified wavelength. The spectrum has absorption

maxima at 257 and 350 nm, and absorption minima at 235 and 313 nm at which the specific absorbance

values are certified, and also at 345 nm, near one of the predicted isobestic points of the spectrum. A detailed discussion of this SRM is given in Special Publication 260-54 which accompanies each unit.

SRM 1930: This SRM complements SRM 930d for the verification and calibration of the transmittance

and absorbance scales of visible absorption spectrometers. SRM 1930 consists of three (3) individual

Schott NG-type glass filters in separate metal cuvette-style holders and an empty filter holder. The nominal percent transmittances of the three filters are 1, 3, and 50%T. The three filters are individually certified for transmittance at five (5) wavelengths in the visible spectrum: 440.0, 465.0, 546.1, 590.0, and 635.0

nm. The optical transmittance neutrality of SRM 1930 is sufficient for the filters to be used to accurately

verify absorption spectrometers with maximum spectral bandpasses ranging from 2.2 to 6.5 nm for the five

wavelengths at which the transmittances are certified. When SRM 1930 is used in combination with SRM

930d, a 6-point stepwise verification of the transmittance scale is possible over the transmittance range

from 1 to 50%T. A detailed discussion of this SRM and SRM 930d is given in Special Publication

260-116 which accompanies each unit.

102
SRM 2009a: This SRM is for use in the verification and calibration of the wavelength scale in the visible

wavelength region of scanning absorption spectrometers having nominal bandwidths in the range 1.5 to

10.5 nm. SRM 2009a consists of a single (1) didymium glass filter in a metal cuvette-style holder. Depending upon the bandwidth of the absorption spectrometer, 12 to 22 wavelength verifications can be determined from 389 to 760 nm. The certified wavelengths correspond to transmittance minima and to

selected inflection points. A detailed discussion of this SRM is given in the Special Publication 260-66

which accompanies each unit.

SRM 2031: This SRM is for the verification and calibration of the transmittance and absorbance scales

of ultraviolet and visible absorption spectrometers. SRM 2031 consists of three (3) individual non-fluorescent, fused-silica filters in separate metal cuvette-style holders and an empty filter holder. The nominal

percent transmittances of the three filters are 10, 30, and 90%T. The fused-silica base plates of the 10

and 30%T filters carry different thicknesses of semi-transparent chromium metal that are optically contacted to fused-silica cover plates. The nominal 90%T filter is a single clear fused-silica plate. The three

filters are individually certified for transmittances at ten (10) wavelengths in the ultraviolet and visible

spectral regions: 250.0, 280.0, 340, 360.0, 400.0, 465.0, 500.0, 546.1, 590.0, and 635.0 nm. The optical transmittance neutrality of SRM 2031 is such that wider spectral bandpasses can be used. Consequently, SRM

2031 is the only transmittance SRM that is suitable for use with those absorption spectrometers with large

spectral bandpasses, e.g., 8 to 20 nm. A detailed discussion of this SRM is given in Special Publication

260-68 which accompanies each unit.

NOTE: Because the 10 and 30%T chromium-coated filters attenuate incident radiation by reflection to a

large extent, SRM 2031 may possibly generate interreflections between optical surfaces in the sample compartment of some absorption spectrometers. Such interreflections may result in isochromatic stray radiant

energy that affects the accuracy of the transmittance measurement. Consequently, when contemplating the

purchase of SRM 2031, the user should contact the instrument manufacturer to verify that metal-on-fused

silica filters are compatible with the spectrometer.

SRM 2032: This SRM is for use in the assessment of heterochromatic stray radiation energy (stray light)

in ultraviolet absorption spectrometers in the spectral region below 260 nm. Issued in 25-g units, SRM

2032 consists of reagent-grade crystalline potassium iodide (KJ). Solutions of this SRM in distilled water

are certified for their specific absorbances under well-defined conditions at 240, 245, 250, 255, 260, 265,

270, and 275 nm. The KI solutions exhibit sharp cutoffs in transmittances below about 260 nm. The user must prepare a liquid KI solution from SRM 2032 and then transfer it to a cuvette of known pathlength.

The certified specific absorbance for the solution prepared is then converted to its corresponding refer- ence transmittance or absorbance value using Beer's Law. The amount of heterochromatic stray light in

the absorption spectrometer at a wavelength below 260 nm may be determined from the equations given

in the certificate.

SRM 2033: This SRM has two different purposes in the assessment of stray radiant energy (stray light)

in ultraviolet absorption spectrometers in the spectral region below 260 nm: (1) an extended dynamic

range test for heterochromatic stray light, and (2) an assessment of isochromatic stray light. In addition to the reagent-grade crystalline potassium iodide as issued in SRM 2032, SRM 2033 also includes a radiation

attenuator to extend the dynamic range of the heterochromatic stray light test for those absorption spectrometers that can not make measurements in the low-transmittance region. The radiation attenuator consists of two (2) non-fluorescent, semi-transparent metal-on-fused silica filters, each having a nominal

percent transmittance of 10%T. One filter is mounted in a metal cuvette-style holder, and the other filter

is mounted in one of the two removable sliding shutters of the holder. For the extended dynamic range

test of heterochromatic stray light, the cuvette containing the KI solution is inserted into the sample-beam

position and the radiation attenuator is used to provide stepwise 10- and 100-fold attenuations of the ref- erence beam. For the isochromatic stray light test, the KI solution is not used, and the metal-on-fused

silica filter is inserted into the sample-beam position.

103
SRM 2034: This SRM is for use in the verification and calibration of the wavelength scale of ultraviolet

and visible absorption spectrometers having nominal spectral bandwidths not exceeding 3 nm. SRM 2034,

a liquid consisting of 4% (w/v) holmium oxide in an aqueous solution of 10% (v/v) perchloric acid, is sealed in a non-fluorescent, fused-silica cuvette of optical quality. SRM 2034 is batch-certified for wavelength location of minimum transmittance of 14 bands in the spectral range from 240 to 650 nm for sue spectral bandwidths from 0.1 to 3 nm. A detailed discussion of this SRM is given in Special Publication

260-102 which accompanies each unit.

SRM 936: This SRM is for use in the evaluation of methods and the calibration of fluorescence spectrometers. Issued in 1-g units, SRM 936 consists of solid quinine sulfate dihydrate. It is certified for the

relative molecular emission spectrum, E(\), in radiometric units for a solution of 1.28 xlO-6 mol/L

quinine sulfate dihydrate in 0.105 mol/L perchloric acid using an excitation wavelength of 347.5 nm. The

values of the molecular emission spectrum are certified at 5-nm wavelength intervals from 375 to 675 nm.

The user must prepare the solution and transfer it to a cuvette of known pathlength. A detailed discussion of this SRM is given in Special Publication 260-64 which accompanies each unit.

SRM 1931: This SRM is for use in the evaluation and calibration of the relative spectral response of flu- orescence spectrometers. It consists of four fluorescence standards and a "blank" specimen mounted in

anodized aluminum cuvette-sized holders. The standards are composed of inorganic phosphors in a sintered polytetrafluoroethylene matrix. The fluorescence standards are certified for the relative corrected

emission spectrum, E(\), in energy/wavelength units. The values of the blue (400-550 nm), green

(490-600 nm), yellow (490-740 nm) and orange (530-740 nm) emission spectra are certified at 2-nm wavelength intervals. SRM 1931 L and R are oriented for left- and right-handed fluorescence spectrometers,

respectively, as defined by viewing the fluorescent sample along the excitation beam. If the first emission

optical component is located to the right of the sample then this orientation is designated R, and if it is to the left then it is designated L.

The SRMs in the following four (4) pages are shipped express or air freight (shipping charges collect). The

amount of a radionuclide in an SRM, at a specified time, is stated as (1) the number of atoms (or the mass

for old radium SRMs), (2) the activity, or "decays per second," or (3) the emission rate of a particular

radiation, depending on the method of calibration or the intended use. For solution SRMs, the quantity is usually specified per gram of liquid. The active portion of gamma-ray "point-source" standards is usually

restricted to the central few millimeters of a low-mass, low-Z support to minimize scattering. Alpha

particle-emitting radionuclides are deposited or plated on metal backings.

The unit for activity has traditionally been the curie (Ci), but simpler relations between activity, emission rate, and counting rate result if the current SI (International System of Units) unit "1 per second" is used. This is symbolized as "s"

1 " and has been given the special name becquerel (Bq). The relationship

between the curie and the becquerel is: 1 Ci = 3.7 x 1010 Bq.

Many SRMs are measured and certified in terms of emission rate. In this catalog, as

The SRMs without an asterisk (*) may be ordered singly, without a license, under the general licensing

provisions of the Atomic Energy Act of 1954, As Amended. Those marked by an asterisk (*) are available

only under the special licensing provisions of the Atomic Energy Act of 1954, As Amended.

NOTE: Certain radionuclides are not economical to maintain in stock because of short half lives or low

demand. When sufficient demand exists, based on letters of inquiry, these materials are prepared and users who have expressed interest are notified of their availability. Requests for any radionuclide not listed, should

be submitted to the Radioactivity Group, Ionizing Radiation Division, Room C114 Radiation Physics Building, National Institute of Standards and Technology, Gaithersburg, MD 20899: Telephone (301) 975-5531;

FAX (301) 869-7682.

In addition, chemically stable solutions of many radionuclides may be submitted to NIST for calibration

as described in Calibration Services User? Guide, NIST Special Publication 250 (1992 Edition). Requests

for such tests should be submitted, with full source information, for approval of suitability to the Radioactivity Group at the above address.

Natural Matrix Materials (powder form)

SRM 4350B- Columbia River Sediment

This material was collected from a river downstream from a nuclear reactor facility. Concentrations of

fission and activation products are elevated over typical world-wide levels. ^'^Pu and 241 Am are very

homogeneously distributed through the sample and are in acid-leachable forms. Inhomogeneity is 3% or

better for other radionuclides.

SRM 4351 -Human Lung

This material contains radioactivity concentrations on the order of 10" 4 Bq g" 1

. It has been freeze-dried,

cryogenically ground, homogenized, and packed in a glass bottle under vacuum. There is significant

inhomogeneity in m,2*°Pu which is unavoidable because plutonium was taken into the lungs in particulate

form. Assessments of accuracy of measurement techniques can be improved by averaging over several

samples.

SRM 4352 -Human Liver

This material contains radioactivity concentrations on the order of 10" 4 Bq g

-1

. It has been freeze-dried,

SRM 4353 -Rocky Flats Soil Number 1 This material was collected within 13 cm of the soil surface at Rocky Flats, CO. ^"^Pu and 240Am

concentrations are about an order of magnitude higher than typical world-wide levels. Approximately

10% of the plutonium is in a acid-resistant form. The material also contains "hot" particles and a statistical

method is provided for dealing with these. Inhomogeneities, excluding hot particles, are on the order of 3%

or better.

SRM 4354 -Freshwater Lake Sediment

This material (gyttja) contains approximately 25 g of freeze-dried, pulverized freshwater lake sediment

(approximately 50% organic by weight) in a polyethylene bottle. The SRM is intended for use in tests of

measurements of environmental radioactivity contained in matrices similar to the sample, for evaluating

analytical methods, or as a generally available calibrated "real" sample matrix in interlaboratory

comparisons.

SRM 4355 -Peruvian Soil

This material has non-measurable radioactivity concentrations for many fallout radionuclides and can be

used as a blank or for sensitive tests of radioanalytical procedures at low-radioactivity concentrations for

other radionuclides. The results of a trace-element study are given for 57 elements.

Bleached Kraft Pulps (sheet form)

These Reference Materials, RMs 8495 Northern Softwood Bleached Kraft Pulp and 8496 Eucalyptus Hardwood Bleached Kraft Pulp, are intended primarily for use in fundamental studies on the physical properties

of fibers and paper sheets. The materials selected for these two RMs are bleached dried lap pulp, each

from a single lot of a standard commercial production run. The materials were selected because of their differing fiber size, differing papermaking properties, and similarity to commercially available materials.

RMs 8495 and 8496 were developed and prepared with input and support from the Pulp Material

Research Committee (PMRC), a sub-committee of the Fundamental Research Committee. These materials

were donated by industry and are being distributed by the Standard Reference Materials Program. At this

time, no extensive property measurements have been made on these materials beyond ensuring they were

within the control limits of the normal production run. A measurement error study is in progress with

participation by international paper technical laboratories. As results become available, they will be published and added to the Report of Investigation that accompanies each of these materials.

* Until ASTM Standard E-23 is modified to include the use of super high energy specimens for machine certification,

these specimens can only be used as reference materials; they cannot be used for certification of Charpy V-Notch testing

machines. Incorporation of the super high energy specimens into the above standard is currently being balloted by

ASTM. Meanwhile, the user should send the fractured specimens and completed questionnaire to the National

Institute of Standards and Technology (NIST), which will review the data and issue a report of its findings to the

user's facility. If the user's machine produces acceptable values, this report will document the conformance

(acceptable operation) of the machine. If the machine produces values outside the acceptable tolerance of the

nominal energy value, this report will suggest changes (machine design, repair or replacement of worn parts,

changes in testing procedures, etc.) to bring the machine into conformance.
