CONSUMER PRODUCT SAFETY COMMISSION
16 CFR Parts 1630 and 1631
Technical Amendment to the Flammability Standards for Carpets and
Rugs
AGENCY: Consumer Product Safety Commission.
ACTION: Final amendments.
-----------------------------------------------------------------------
SUMMARY: The Commission is amending the flammability standards for
carpets and rugs to remove the reference to Eli Lilly Company Product
No. 1588 in Catalog No. 79, December 1, 1969, as the standard ignition
source and provide a technical specification defining the ignition
source. The specification for the standard ignition source is a timed
burning tablet, consisting of essentially pure methenamine, with a
nominal heat of combustion value of 7180 calories/gram, a mass of 150
mg +/-5 mg, flat, and a nominal diameter of 6 mm. The amendment has an
immediate effective date.
DATES: The amendment is effective October 26, 2007.

Commission, Washington, DC 20207; telephone (301) 504-7536.
SUPPLEMENTARY INFORMATION:
A. Background
The standards for surface flammability of carpets and rugs appear
at 16 CFR parts 1630 and 1631. They were codified and published in
1975, 40 FR 59931 and 59935 (December 30, 1975). The standards were
originally issued in 1970 by the Department of Commerce under the
authority of the Flammable Fabrics Act (FFA). Subpart A of 16 CFR parts
1630 and 1631 set forth the standards. Subpart B contains the
implementing regulations of the standards. Subpart C contains
alternative washing procedures for hide carpets and rugs and wool
flotaki carpets and rugs. Subpart D of 16 CFR part 1630 contains the
staff interpretations and policies.
16 CFR parts 1630 and 1631 establish minimum acceptance criteria
for the surface flammability of carpets and rugs when exposed to a
standard small source of ignition, a burning methenamine tablet, under
prescribed conditions (the ``pill test''). These standards reduce the
risks of death, personal injury, and property damage associated with
fires that result from the surface ignition of carpets and rugs.
Both standards require a timed burning tablet as the standard
ignition source for flammability performance testing. The standards
define the ignition source at 1630.1(f) and 1631.1(f) as a methenamine
tablet, weighing approximately 0.149 grams (2.30 grains), sold as
Product No. 1588 in Catalog No. 79, December 1, 1969 by the Eli Lilly
Company, or an equal tablet.
In April 2002, Commission staff learned that the Eli Lilly Company
was no longer producing the methenamine tablets specified in the carpet
and rug standards. Although the standards allow for the use of ``an
equal'' methenamine tablet and give parameters for chemical composition
and weight of the tablet, they do not provide any guidance on
determining whether tablets from alternative sources are ``equal'' to
those manufactured by the Eli Lilly Company. In July 2003, CPSC staff
met with representatives of the Carpet and Rug Institute (CRI) to
discuss evaluation of alternative methenamine tablets for use in 16 CFR
part 1630 and Part 1631. CRI members were experiencing differing test
results using the old Eli Lilly tablets and currently available
tablets. CRI members had begun to study the various characteristics of
the current tablets. In one case, about 50% of one manufacturer's
tablets were found broken in the bottle, with others breaking later.
This problem was attributed to the tablets having a domed top. The
problem has since been corrected with a flat tablet.
CRI urged the Commission to specify clearly the characteristics of
the ``equal'' tablets that should be used for determining compliance to
the carpet and rug standards. In an effort to make such a
determination, the Commission staff conducted a comparison study to
evaluate the weight, chemical composition, and combustion
characteristics of presently available brands of methenamine tablets
relative to each other and those produced by the Eli Lilly Company. The
outcome of the study indicated that tablets consisting of essentially
pure methenamine, having a heat of combustion value of approximately
7180 calories/gram and weighing approximately 0.149 grams may be
considered equivalent to the tablets produced by the Eli Lilly Company
and referenced in the regulation.
On July 29, 2004, the Commission's Office of Compliance issued a
letter to industry in response to inquiries received by the CPSC staff
regarding the equivalency of methenamine tablets formerly manufactured
by the Eli Lilly Company and similar tablets currently produced by
other manufacturers. The letter stated that the Commission staff
determined that tablets consisting of essentially pure methenamine and
weighing approximately 0.149 grams may be considered equivalent to the
tablets formerly produced by the Eli Lilly Company. Therefore, tablets
meeting these criteria may be used for purposes of determining
conformance with the carpet and rug standards.
B. Amending the Flammability Standards
1. Outcome of Commission Testing
As mentioned above, the Eli Lilly Company is no longer producing
the methenamine tablets specified in the carpet and rug standards. The
standards allow for the use of ``an equal'' methenamine tablet and give
parameters for chemical composition and weight of the tablet, but they
do not provide any guidance on determining whether tablets from the
alternative sources are ``equal'' to those manufactured by the Eli
Lilly Company. The Commission staff conducted a comparison study to
evaluate the weight, chemical composition, and combustion
characteristics of presently available brands of methenamine tablets
relative to each other and those produced by the Eli Lilly Company. The
outcome of the Commission's comparative study
[[Page 60766]]
indicated that tablets consisting of essentially pure methenamine,
having a heat of combustion value of approximately 7,180 calories/gram
and weighing approximately 0.149 grams may be considered equivalent to
the tablets produced by the Eli Lilly Company and referenced in the
regulation.
2. Proposed Amendment
On November 13, 2006, the Commission issued a Federal Register
notice to amend the flammability standards for carpets and rugs to
remove the reference to the Eli Lilly Company's tablet as the standard
ignition source and provide a generic specification defining the
ignition source at Sec. 1630.1(f) and Sec. 1631.1(f) and solicited
public comments. The Commission received one comment in support of the
proposal, and one objecting to flammability testing as a mandatory
requirement and recommending that compliance with the standards be
voluntary to avoid potential trade restrictions on woolen rugs.
On January 12, 2007, the Commission issued a Federal Register
notice providing interested persons the opportunity for oral or written
presentations regarding the proposed technical amendment to the
flammability standards for carpets and rugs. No responses to the
Federal Register notice were received.
3. Final Rule
The carpet and rug flammability standards were issued under section
4 of the FFA (15 U.S.C. 1193), which authorizes the issuance or
amendment of flammability standards to protect the public against
unreasonable risks of fire leading to death, personal injury, or
significant property damage. As required by section 4(b) of the FFA,
both standards are based on findings that they are needed to adequately
protect the public against the unreasonable risk of the occurrence of
fire leading to death, personal injury, or significant property damage.
Section 4(j)(1) of the Flammable Fabrics Act requires the
Commission to prepare a final regulatory analysis before issuing a
final rule. The regulatory analysis must contain a description of the
potential benefits and costs of the regulation, a description of any
alternatives to the final regulation, and a summary of any significant
issues raised by the comments submitted during the public comment
period. The Commission must also find that the benefits expected from
the rule bear a reasonable relationship to its costs and that the rule
imposes the least burdensome requirement which prevents or adequately
reduces the risk of injury for which the regulation is being
promulgated. 15 U.S.C. 1193(j)(2).
Potential Costs and Benefits
Since 2002, when production of the previous methenamine tablet was
discontinued by its manufacturer, producers and importers of carpets
and rugs that comply with the standards have been performing tests with
``equivalent'' methenamine tablets. The technical amendment will,
therefore, maintain current industry practice. The technical amendment
to redefine the methenamine tablet will have no significant impact on
expected benefits or costs of the flammability standards for carpets
and rugs.
4. Comments
The Commission received two comments on the proposed rule. The
American Fiber Manufacturers Associated supported the technical
amendment as proposed. The Permanent Mission of India to the World
Trade Organization objected to flammability as a mandatory requirement
and recommended that compliance with the standards be voluntary to
avoid potential trade restrictions on woolen rugs. The Commission notes
that the standards have been in effect since 1970; the amendment only
provides a generic specification for the ignition source and will not
alter the overall scope of the standards. Thus, the amendment will have
no impact on U.S. or international trade.
Review of Other Existing Standards
The Commission staff is aware of one U.S. voluntary standard
regarding the type of ignition source to be used in testing the
flammability of carpets and rugs. This standard, ASTM D2859-04,
``Standard Test Method for Ignition Characteristics of Finished Textile
Floor Covering Materials,'' describes the use of the Eli Lilly Tablet
as satisfactory. It also states that ``normal variation in the weight
of the different tablets will not affect the test results.''
There is an existing international voluntary standard developed by
the International Organization for Standardization in 1982 (ISO 6925),
that describes a tablet test for the flammability of textile floor
coverings. The prescribed tablets are of ``hexamethylenetetramine,
flat, having a mass of 150mg (plus or minus 5mg) and a diameter of
6mm.'' The allowable variance is about 3.3%. The mass expressed in ISO
6925 is essentially equivalent to that specified in the U.S. Standards
under the FFA. While the ISO standard did not identify the Eli Lilly
tablet, it noted that the tablets were commercially available. Thus,
the ISO-specified tablet is equivalent to the Eli Lilly tablet in its
specifications.
Canada's 1973 mandatory standard for carpets and textile floor
coverings under the Hazardous Products Act, CGSB 4-GP-2, also specifies
in its appendix the Eli Lilly tablet as the ignition source. It notes
that ``normal variation in weight * * * will not affect the test
results.''
5. Effective Date
Section 4(b) of the FFA (15 U.S.C. 1193(b)) provides that an
amendment of a flammability standard shall become effective one year
from the date it is promulgated, unless the Commission finds for good
cause that an earlier or later effective date is in the public
interest, and publishes that finding. Because manufacturers are already
using ``equal'' methenamine tablets as allowed by the current
standards, the Commission finds that an immediate effective date upon
publication of the amendments is appropriate.
C. Other Issues
1. Impact on Small Businesses
In accordance with section 605(b) of the Regulatory Flexibility Act
(5 U.S.C. 605(b)), in the proposed rule, the Commission preliminarily
certified that these amendments to the carpet and rug flammability
standards would not have a significant economic impact on a substantial
number of small entities, including small businesses. 71 FR 66,145. No
information available to the Commission since the issuance of the
proposed rule warrants changing this preliminary certification. The
amendments keep current industry practices and procedures in place. No
additional actions will be required of small entities. Based on
available information, there will be little or no effect on small
producers of carpets and rugs, since the standards already require that
all carpets and rugs meet the criteria of the tests, and, given the
equivalence of the test tablets, the results of the tests should be the
same. Accordingly, the Commission certifies that this final rule will
not have a significant economic impact on a substantial number of small
entities.
2. Environmental Considerations
The amendments fall within the categories of Commission actions
described at 16 CFR 1021.5(c) that have little or no potential for
affecting the human environment. The amendments are not expected to
have a significant
[[Page 60767]]
effect on production processes or on the types or amounts of materials
used for the manufacture of carpets and rugs. The amendments will not
render existing inventories unsalable, or require destruction of
existing goods. The Commission has no information indicating any
special circumstances in which these amendments may affect the human
environment. For that reason, as discussed in the proposed rule,
neither an environmental assessment nor an environmental impact
statement is required. 71 FR 66145.
3. Executive Order 12988
Executive Order 12988, Civil Justice Reform, (February 5, 1996),
requires that the Commission specify the preemptive effect, if any, to
be given each new regulation. This technical amendment does not alter
the preemptive effect of the underlying regulation.
