37318 Federal Register / Vol. 65, No. 115 / Wednesday, June 14, 2000 / Proposed Rules

by the Commission to assist members of

the furniture industry in complying

with section 5 of the FTC Act. The

Federal Register Notice (‘‘notice’’)

posed eleven questions in all; some

were general regulatory review

questions, while others asked about

material issues that are specific to the

household furniture industry. Pursuant

to the Federal Register notice, the

comment period relating to the

Household Furniture Guides currently

ends on June 9, 2000.

The Commission received a request

for an extension of the comment period

from the American Furniture

Manufacturers Association (‘‘AFMA’’).

AFMA has indicated that additional

time is required so that its members can

prepare thorough, thoughtful responses

to the proposals and questions

contained in the Federal Register

notice.

The Commission is mindful of the

need to deal with this matter as

expeditiously as possible. However, the

Commission is also aware that some of

the issues raised by the Federal Register

notice may be complex and it welcomes

as much substantive input as possible to

facilitate its decisionmaking process.

Accordingly, in order to provide

sufficient time for these and other

interested parties to prepare useful

comments, the Commission has decided

to extend the deadline for comments

until July 10, 2000.

Authority: 15 U.S.C. 41–58.

CONSUMER PRODUCT SAFETY

COMMISSION

16 CFR Part 1211

Safety Standard for Automatic

Residential Garage Door Operators

AGENCY: Consumer Product Safety

Commission.

ACTION: Notice of proposed rulemaking.

SUMMARY: The Consumer Product Safety

Commission is proposing to amend

regulations on the Safety Standard for

Automatic Residential Garage Door

Operators to reflect changes made by

Underwriters Laboratories, Inc. in its

standard UL 325.

DATES: The Office of the Secretary must

receive comments by August 28, 2000.

ADDRESSES: Comments may be mailed to

the Office of the Secretary, Consumer

Product Safety Commission,

Washington, DC 20207 or delivered to

the Office of the Secretary, Consumer

Product Safety Commission, Room 502,

4330 East-West Highway, Bethesda,

Maryland 20814–4408, telephone (301)

504–0800. Comments may also be filed

by telefacsimile to (301) 504–0127 or emailed to cpsc-os@cpsc.gov.

FOR FURTHER INFORMATION CONTACT: John

Murphy, Directorate for Engineering

Sciences, Consumer Product Safety

Commission, Washington, DC 20207,

telephone 301–504–0494.

SUPPLEMENTARY INFORMATION: The

Commission issued part 1211 on

December 21, 1992 to minimize the risk

of entrapment by residential garage door

openers. As mandated by section 203 of

Public Law 101–608, subpart A of part

1211 codifies garage door operator

entrapment provisions of Underwriter

Laboratories, Inc. (‘‘UL’’) standard UL

325, third edition, ‘‘Door, Drapery,

Louver and Window Operators and

Systems.’’ Subparagraph (c) of section

203 of Pub. L. 101–608 also required the

Commission to incorporate into part

1211 any revisions that UL proposed to

the entrapment protection requirements

of UL 325, unless the Commission

notified UL that the revision does not

carry out the purposes of Pub. L. 101–

608.

UL proposed revisions to UL 325 on

June 30, 1998 and made them final on

September 18, 1998. The Commission

determined that the entrapment related

revisions do carry out the purposes of

Public Law 101–608. This proposed rule

would incorporate into subpart A of part

1211 those revisions that relate to

entrapment by residential automatic

garage door operators. It would also

correct a few typographical errors in

part 1211.

The changes to the UL standard allow

for advances in the state of the art in

garage door safety. Some new garage

door operators have an inherent

entrapment protection system that can

continuously monitor the position of the

door. The UL revisions add

requirements for this type of system.

Some new garage door operators have

an inherent secondary door sensor that

is independent of the primary

entrapment protection system. The UL

revisions add requirements for this type

of new system. Finally, the UL standard

adds some new and revised provisions

concerning instructions and field

installed labels. The proposed rule

would incorporate these changes into

the CPSC mandatory standard.

Pursuant to section 605(b) of the

Regulatory Flexibility Act, 5 U.S.C.

605(b), the Commission certifies that

this rule will not have a significant

impact on a substantial number of small

entities. Most of the changes are

editorial and minor. The substantive

changes only affect the few companies

that are developing the new type of

garage door operators discussed above.

Moreover, UL has already made these

changes to its UL 325 standard which is

widely followed by the industry. The

Commission also certifies that this rule

will have no environmental impact. The

Commission’s regulations state that

safety standards for products normally

have little or no potential for affecting

the human environment. 16 CFR

1021.5(c)(1). Nothing in this proposed

rule alters that expectation.

Public Law 101–608 contains a

preemption provision. It states: ‘‘those

provisions of laws of States or political

subdivisions which relate to the labeling

of automatic residential garage door

openers and those provisions which do

not provide at least the equivalent

degree of protection from the risk of

injury associated with automatic

residential garage door openers as the

consumer product safety rule’’ are

subject to preemption under 15 U.S.C.

2075. Pub. L. 101–608, section 203(f).

List of Subjects in 16 CFR Part 1211

Consumer protection, Imports,

Labeling, Reporting and recordkeeping

requirements.

Accordingly, 16 CFR part 1211 is

proposed to be amended as follows:

PART 1211—SAFETY STANDARDS

FOR AUTOMATIC RESIDENTIAL

GARAGE DOOR OPENERS

1. The authority citation for part 1211

is revised to read as follows:

Authority: Sec. 203 of Pub. L. 101–608, 104

Stat. 3110; 15 U.S.C. 2063 and 2065.

2. In § 1211.2(c) remove the word

‘‘1993’’ and add, in its place ‘‘1999’’.

3. In the first sentence of § 1211.3

remove the words ‘‘as given in these

requirements’’ and ‘‘an equivalent’’ and

add the word ‘‘a’’ between the words

‘‘by’’ and ‘‘value’’.

4. Section 1211.4 is amended as

follows:

a. In § 1211.4(c) remove the words

‘‘1st ed., dated July 19, 1991’’ and add,

in their place ‘‘second edition, dated

June 23, 1995’’.

b. In § 1211.4(c) add ‘‘5’’ before

‘‘U.S.C.’’.

5. Section 1211.5 is amended as

follows:

Federal Register / Vol. 65, No. 115 / Wednesday, June 14, 2000 / Proposed Rules 37319

a. In § 1211.5(a) and (b)(3) remove the

words ‘‘1st ed., dated July 19, 1991’’ and

add, in their place ‘‘second edition,

dated June 23, 1995’’.

b. Revise paragraphs (a)(1), (a)(6), and

(a)(7); and add a new paragraph (a)(9) to

read as follows:

§ 1211.5 General testing parameters.

(a) * * *

(1) With regard to electrical

supervision of critical components, an

operator being inoperative with respect

to downward movement of the door

meets the criteria for trouble indication.

* * * * *

(6) When a Computational

Investigation is conducted, λp shall not

be greater than 6 failures/106 hours for

the entire system. For external

secondary entrapment protection

devices that are sold separately, λ shall

not be greater than 0 failures/106 hours.

For internal secondary entrapment

protection devices whether or not they

are sold separately, λp shall not be

greater than 0 failures/106 hours. The

operational test is conducted for 14

days. An external secondary entrapment

protection device that is sold separately,

and that has a λp greater than 0 failures/

106 hours meets the intent of the

requirement when for the combination

of the operator and the specified

external secondary entrapment

protection device λp does not exceed 6

failures/106 hours. See § 1211.15(i) and

(k).

(7) When the Demonstrated Method

Test is conducted, the multiplier is to be

based on the continuous usage level,

and a minimum of 24 units for a

minimum of 24 hours per unit are to be

tested.

(8) * * *

(9) For the Electrical Fast Transient

Burst Test, test level 3 is to be used for

residential garage door operators.

* * * * *

6. Section 1211.6 is amended by

revising paragraphs (a), (b) introductory

text, (b)(1)(ii), (b)(1)(iii), (b)(2), adding a

new paragraph (b)(3), revising

paragraphs (c) and (d), and removing

paragraph (e) to read as follows:

§ 1211.6 General entrapment protection

requirements.

(a) A residential garage door operator

system shall be provided with primary

inherent entrapment protection that

complies with the requirements as

specified in § 1211.7.

(b) In addition to the primary inherent

entrapment protection as required by

paragraph (a) of this section, a

residential garage door operator shall

comply with one of the following:

(1) * * *

(i) * * *

(ii) Reverse direction and open the

door to the upmost position when

constant pressure on a control is

removed prior to operator reaching its

lower limit, and

(iii) Limit a portable transmitter,

when supplied, to function only to

cause the operator to open the door;

(2) Shall be provided with a means for

connection of an external secondary

entrapment protection device as

described in § 1211.8, 1211.10, and

1211.11; or

(3) Shall be provided with an inherent

secondary entrapment protection device

as described in § 1211.8, 1211.10, and

1211.12.

(c) A mechanical switch or a relay

used in an entrapment protection circuit

of an operator shall withstand 100,000

cycles of operation controlling a load no

less severe (voltage, current, power

factor, inrush and similar ratings) than

it controls in the operator, and shall

function normally upon completion of

the test.

(d) In the event malfunction of a

switch or relay (open or short) described

in paragraph (c) of this section results in

loss of any entrapment protection

required by §§ 1211.7(a), 1211.7(f), or

1211.8(a), the door operator shall

become inoperative at the end of the

opening or closing operation, the door

operator shall move the door to, and

stay within, 1 foot (305 mm) of the

uppermost position.

7. Revise § 1211.7 to read as follows:

§ 1211.7 Inherent entrapment protection

requirements.

(a) Other than the first 1 foot (305mm)

of travel as measured over the path of

the moving door, both with and without

any external entrapment protection

device functional, the operator of a

downward moving residential garage

door shall initiate reversal of the door

within 2 seconds of contact with the

obstruction as specified in paragraph (b)

of this section. After reversing the door,

the operator shall return the door to,

and stop at, the full upmost position,

unless an inherent entrapment circuit

senses a second obstruction or a control

is actuated to stop the door during the

upward travel. Compliance shall be

determined in accordance with

paragraphs (b) through (i) of this

section.

(b) A solid object is to be placed on

the floor of the test installation and at

various heights under the edge of the

door and located in line with the

driving point of the operator. When

tested on the floor, the object shall be

1 inch (25.4 mm) high. In the test

installation, the bottom edge of the door

under the driving force of the operator

is to be against the floor when the door

is fully closed. For operators other than

those attached to the door, the solid

object is to be located at points at the

center, and within 1 foot of each end of

the door.

(c) An operator is to be tested for

compliance with paragraph (a) of this

section for 50 open-and-close cycles of

operation while the operator is

connected to the type of residential

garage door with which it is intended to

be used or with the doors specified in

paragraph (e) of this section. For an

operator having a force adjustment on

the operator, the force is to be adjusted

to the maximum setting or at the setting

that represents the most severe

operating condition. Any accessories

having an effect on the intended

operation of entrapment protection

functions that are intended for use with

the operator, are to be attached and the

test is to be repeated for one additional

cycle.

(d) For an operator that is to be

adjusted (limit and force) according to

instructions supplied with the operator,

the operator is to be tested for 10

additional obstruction cycles using the

solid object described in paragraph (b)

of this section at the maximum setting

or at the setting that represents the most

severe operating condition.

(e) For an operator that is intended to

be used with more than one type of

door, one sample of the operator is to be

tested on a sectional door with a curved

track and one sample is to be tested on

a one-piece door with jamb hardware

and no track. For an operator that is not

intended for use on either or both types

of doors, a one-piece door with track

hardware or a one-piece door with pivot

hardware shall be used for the tests. For

an operator that is intended for use with

a specifically dedicated door or doors, a

representative door or doors shall be

used for the tests. See the marking

requirements at § 1211.16.

(f) An operator, using an inherent

entrapment protection system that

monitors the actual position of the door,

shall initiate reversal of the door and

shall return the door to, and stop the

door at, the full upmost position in the

event the inherent door operating

‘‘profile’’ of the door differs from the

originally set parameters. The

entrapment protection system shall

monitor the position of the door at

increments not greater than 1 inch (25.4

mm). The door operator is not required

to return the door to, and stop the door

at, the full upmost position when an

inherent entrapment circuit senses an

obstruction or a control is actuated to

stop the door during the upward travel.

37320 Federal Register / Vol. 65, No. 115 / Wednesday, June 14, 2000 / Proposed Rules

(g) An operator, using an inherent

entrapment protection system that does

not monitor the actual position of the

door, shall initiate reversal of the door

and shall return the door to and stop the

door at the full upmost position, when

the lower limiting device is not actuated

in 30 seconds or less following the

initiation of the close cycle. The door

operator is not required to return the

door to and stop at the full upmost

position when an inherent entrapment

circuit senses an obstruction or a control

is actuated to stop the door during the

upward travel. When the door is

stopped manually during its descent,

the 30 seconds shall be measured from

the resumption of the close cycle.

(h) To determine compliance with

paragraph (f) or (g) of this section, an

operator is to be subjected to 10 openand-close cycles of operation while

connected to the door or doors specified

in paragraphs (c) and (e) of this section.

The cycles are not required to be

consecutive. Motor cooling-off periods

during the test meet the intent of the

requirement. The means supplied to

comply with the requirement in

paragraph (a) of this section and

§ 1211.8(a) are to be defeated during the

test. An obstructing object is to be used

so that the door is not capable of

activating a lower limiting device.

(i) During the closing cycle, the

system providing compliance with

paragraphs (a) and (f) or paragraphs (a)

and (g) of this section shall function

regardless of a short-or open-circuit

anywhere in any low-voltage external

wiring, any external entrapment

devices, or any other external

component.

8. Section 1211.8 is revised to read as

follows:

§ 1211.8 Secondary entrapment protection

requirements.

(a) A secondary entrapment

protection device supplied with, or as

an accessory to, an operator shall

consist of:

(1) An external photoelectric sensor

that when activated results in an

operator that is closing a door to reverse

direction of the door and the sensor

prevents an operator from closing an

open door,

(2) An external edge sensor installed

on the edge of the door that, when

activated results in an operator that is

closing a door to reverse direction of the

door and the sensor prevents an

operator from closing an open door,

(3) An inherent door sensor

independent of the system used to

comply with § 1211.7 that, when

activated, results in an operator that is

closing a door to reverse direction of the

door and the sensor prevents an

operator from closing an open door, or

(4) Any other external or internal

device that provides entrapment

protection equivalent to paragraphs

(a)(1), (a)(2), or (a)(3) of this section.

(b) With respect to paragraph (a) of

this section, the operator shall monitor

for the presence and correct operation of

the device, including the wiring to it, at

least once during each close cycle. In

the event the device is not present or a

fault condition occurs which precludes

the sensing of an obstruction, including

an open or short circuit in the wiring

that connects an external entrapment

protection device to the operator and

device’s supply source, the operator

shall be constructed such that:

(1) A closing door shall open and an

open door shall not close more than 1

foot (305 mm) below the upmost

position, or

(2) The operator shall function as

required by § 1211.6(b)(1).

(c) An external entrapment protection

device shall comply with the applicable

requirements in §§ 1211.10, 1211.11 and

1211.12.

(d) An inherent secondary entrapment

protection device shall comply with the

applicable requirements in § 1211.13.

Software used in an inherent

entrapment protection device shall

comply with UL 1998 Standard for

Safety-Related Software, First Edition,

January 4, 1994. This incorporation by

reference was approved by the Director

of the Federal Register in accordance

with 5 U.S.C. 552(a) and 1 CFR part 51.

9. Section 1211.9 is amended by

revising paragraph (a), redesignating

paragraphs (b) and (c) as paragraphs (c)

and (d) respectively, and adding a new

paragraph (b) to read as follows:

§ 1211.9 Additional entrapment protection

requirements.

(a) A means to manually detach the

door operator from the door shall be

supplied. The gripping surface (handle)

shall be colored red and shall be easily

distinguishable from the rest of the

operator. It shall be capable of being

adjusted to a height of 6 feet (1.8 m)

above the garage floor when the operator

is installed according to the instructions

specified in § 1211.14(a)(2). The means

shall be constructed so that a hand

firmly gripping it and applying a

maximum of 50 pounds (223 N) of force

shall detach the operator with the door

obstructed in the down position. The

obstructing object, as described in

§ 1211.7(b), is to be located in several

different positions. A marking with

instructions for detaching the operator

shall be provided as required by

§ 1211.15(i).

(b) A means to manually detach the

door operator from the door is not

required for a door operator that is not

directly attached to the door and that

controls movement of the door so that:

(1) The door is capable of being

moved open from any position other

than the last (closing) 2 inches (50.8

mm) of travel, and

(2) The door is capable of being

moved to the 2–inch point from any

position between closed and the 2–inch

point.

* * * * *

10. Section 1211.10 is amended as

follows:

a. In the first sentence of paragraph

(a)(3), after the word ‘‘minimum’’ add

the words ‘‘and maximum’’; at the

beginning of the second sentence add

the words ‘‘For doors,’’ and revise the

word ‘‘If’’ to read ‘‘if’’.

b. In the first sentence of paragraph

(c)(2) revise the phrase ‘‘An external

entrapment protection device is’’ to read

‘‘External entrapment protection devices

are’’.

c. In paragraphs (d) and (e)(2), remove

the words ‘‘3rd ed., dated July 1, 1991’’

and add, in their place ‘‘4th ed., dated

December 27, 1995’’.

d. In paragraph (d), second sentence,

insert ‘‘5 ‘‘ before ‘‘U.S.C’’

e. In paragraph (e)(1), second

sentence, remove the words ‘‘After

being subjected to this’’ and add, in

their place the words ‘‘As a result of

the’’.

f. In paragraph (e)(1)(ii), add at the

end thereof and before the period the

words ‘‘or, if dislodged after the test, is

capable of being restored to its original

condition’’.

11. Section 1211.12 is amended in

paragraph (c)(2), first sentence, by

removing the words ‘‘3rd ed., dated July

1, 1991’’ and adding in their place ‘‘4th

ed., dated December 27, 1995’’ and in

the second sentence, by inserting ‘‘5’’

before ‘‘U.S.C.’’

12. Redesignate sections 1211.13

through 1211.16 as sections 1211.14

through 1211.17, respectively, and add

a new section 1211.13 to read as

follows:

Federal Register / Vol. 65, No. 115 / Wednesday, June 14, 2000 / Proposed Rules 37321

§ 1211.13 Inherent force activated

secondary door sensors.

(a) Normal operation test. (1) A force

activated door sensor of a door system

installed according to the installation

instructions shall actuate when the door

applies a 15 pound (66.7 N) or less force

in the down or closing direction and

when the door applies a 25 pound

(111.2 N) or less force in the up or

opening direction. For a force activated

door sensor intended to be used in an

operator intended for use only on a

sectional door, the force is to be applied

by the door against the longitudinal

edge of a 17⁄8 (47.6 mm) diameter

cylinder placed across the door so that

the axis is perpendicular to the plane of

the door. See Figure 6 of this part. The

weight of the door is to be equal to the

maximum weight rating of the operator.

(2) The test described in paragraph

(a)(1) of this section is to be repeated

and measurements made at various

representative points across the width

and height of the door. The cycles are

not required to be consecutive.

Continuous operation of the motor

without cooling is not required. For this

test, a door sensor system and

associated components shall withstand

a total of 9 cycles of mechanical

operation without failure with the force

applied as follows:

(i) At the center at points one, three,

and five feet from the floor,

(ii) Within 1 foot of the end of the

door, at points one, three, and five feet

from the floor,

(iii) Within 1 foot of the other end of

the door at points one, three, and five

feet from the floor.

(b) Adjustment of door weight. (1)

With the door at the point and at the

weight determined by the tests of

paragraphs (a)(2) and (b)(2) of this

section to be the most severe, the door

sensor and associated components shall

withstand 50 cycles of operation

without failure.

(2) At the point determined by the test

in paragraphs (a)(1) and (a)(2) of this

section to be the most severe, weight is

to be added to the door in 5.0 pound

(2.26 Kg) increments and the test

repeated until a total of 15.0 pounds

(66.72 N) has been added to the door.

Before performing each test cycle, the

door is to be cycled 2 times to update

the profile. Similarly, starting from

normal weight plus 15.0 pounds, the

test is to be repeated by subtracting

weight in 5.0 pound increments until a

total of 15.0 pounds has been subtracted

from the door.

13. Redesignated section 1211.14 is

amended as follows:

a. In paragraph (a)(4), third sentence,

remove the word ‘‘that’’ and add in its

place ‘‘than’’.

b. In paragraph (b)(1) remove the

initial word ‘‘If’’ (in paragraph 4 of the

installation instructions) and add, in its

place ‘‘Where’’; remove the word

‘‘Mount’’ and add, in its place ‘‘For

products requiring an emergency

release, mount’’.

c. In paragraph (b)(2), in the second

sentence of paragraph 4 of the safety

instructions, remove the number ‘‘1’’

and add in its place the number ‘‘11⁄2’’.

d. In paragraph (b)(2) before the initial

word ‘‘If’’ (in paragraph 5 of the safety

instructions), add ‘‘For products

requiring an emergency release,’’ and

revise the word ‘‘If’’ to read ‘‘if’’.

14. Redesignated section 1211.15 is

amended as follows:

a. In paragraph (g)(1) remove the

words ‘‘A child may become’’ and add,

in their place ‘‘There is a risk of a child

becoming’’.

b. In paragraph (g)(2)(iv) remove the

first word ‘‘If’’ and add, in its place ‘‘In

the event’’.

c. In paragraph (g)(2)(iv) add a second

sentence to read ‘‘For products not

having an emergency release use instead

’In the event a person is trapped under

the door, push the control button’’’.

d. In paragraph (g)(3)(i) in the second

sentence, remove the word ‘‘If’’ and add

it its place ‘‘In the event’’.

e. In paragraph (i) remove the initial

word ‘‘A’’ and add, in its place ‘‘Except

for door operators complying with

§ 1211.9(b), a’’.

SUPPLEMENTARY INFORMATION:

Background

This notice ask experts on growth

impairments in children, and other

interested members of the public, for

comments that will help us decide how

we should revise section 100.00 of the

listings. We use the criteria in the

listings to evaluate disability claims

under both the Social Security disability

insurance (title II) and Supplemental

Security Income (SSI) (title XVI)

programs at the third step of the

sequential evaluation processes for

adults and children. The listings

describe impairments that are

considered severe enough to prevent a

person from doing any gainful activity.

In the case of a child under age 18

seeking SSI benefits based on disability,

the listings describe impairments that

are considered severe enough to cause

marked and severe functional

limitations. For more information on the

definitions of disability and on the

sequential evaluation processes, see 20
