Federal Motor Vehicle Safety Standards; Metric Conversion

AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule amends selected Federal Motor Vehicle Safety 
Standards (FMVSS) by converting English measurements specified in those 
standards to metric measurements. This rulemaking is the first of 
several that NHTSA will undertake to implement the statutory Federal 
policy that the metric system is the preferred system of weights and 
measures for U.S. trade and commerce. The conversions are not intended 
to change the stringency of the affected FMVSS.

DATES: This final rule is effective March 14, 1996. Optional early 
compliance with the changes made in this final rule is permitted 
beginning March 14, 1995.
    Petitions for reconsideration of this final rule must be filed by 
April 13, 1995.

ADDRESSES: Petitions for reconsideration of this final rule should 
refer to the docket and notice number cited in the heading of this 
final rule and be submitted to: Administrator, National Highway Traffic 
Safety Administration, 400 Seventh Street, SW., Washington, DC 20590. 
It is requested but not required, that 10 copies be submitted.

FOR FURTHER INFORMATION CONTACT: Mr. Kevin Cavey, National Highway 
Traffic Safety Administration, 400 Seventh Street, SW., Washington, DC 
20590. Mr. Cavey's telephone number is: (202) 366-5271.

SUPPLEMENTARY INFORMATION: Section 5164 of the Omnibus Trade and 
Competitiveness Act (Pub. L. 100-418), makes it United States policy 
that the metric system of measurement is the [[Page 13640]] preferred 
system of weights and measures for U.S. trade and commerce. Through 
Executive Order 12770, Federal agencies were directed to comply with 
the Act by adopting a conversion schedule for their programs by 
September 30, 1992. In the April 21, 1992 Federal Register (57 FR 
14619), NHTSA published for comment its plan to use the metric system 
in NHTSA programs and included an implementation schedule to convert 
the Federal Motor Vehicle Safety Standards (FMVSSs). NHTSA projected 
simple FMVSS conversions would be completed by June 1994, intermediate 
conversions by December 1996, and the most complex conversions by 
December 1997. NHTSA described how it would convert English 
measurements in the FMVSSs to metric measurements.
    In response to the plan, NHTSA received five public comments. NHTSA 
took all comments into consideration in drafting a notice of proposed 
rulemaking (NPRM) to convert English measurements in selected FMVSS to 
metric measurements.

Notice of Proposed Rulemaking

    NHTSA published on March 15, 1994 (59 FR 11962) a proposal 
identifying the standards for which NHTSA believed conversions of 
English measurements to metric measurements would be simple and 
proposed the appropriate conversions to the metric system. English 
measurements in the following Federal Motor Vehicle Safety Standards 
(49 CFR 571 et seq.) were proposed to be converted to the metric 
system: Standard No. 102, Transmission shift lever sequence, starter 
interlock, and transmission braking effect; Standard No. 103, 
Windshield defrosting and defogging systems; Standard No. 104, 
Windshield wiping and washing systems; Standard No. 107, Reflecting 
surfaces; Standard No. 110, Tire selection and rims; Standard No. 112, 
Headlamp concealment devices; Standard No. 114, Theft protection; 
Standard No. 115, Vehicle identification number--basic requirements; 
Standard No. 120, Tire selection and rims for motor vehicles other than 
passenger cars; Standard No. 124, Accelerator control systems; Standard 
No. 126, Truck-camper loading; Standard No. 205, Glazing materials; 
Standard No. 206, Door locks and door retention components; Standard 
No. 207, Seating systems; Standard No. 212, Windshield mounting; and 
Standard No. 216, Roof crush resistance.
    In the NPRM, NHTSA highlighted three issues for public comment: 
whether conversions should be exact or equivalent; how consumer 
information in labels should be converted; and how force measurements 
should be converted.
    Because using values stated in integers would make it easier to 
make measurements in compliance testing, NHTSA proposed to favor 
equivalent conversions, not exact conversions. To illustrate the 
difference between equivalent and exact conversions, an equivalent 
conversion of two inches would be 50 millimeters, while an exact 
conversion would be 50.8 millimeters. NHTSA asked the commenters to 
indicate any instance in which they believed that an equivalent 
conversion might have a substantive effect on a standard, and requested 
that the commenters suggest in those instances an exact conversion. 
With respect to those requirements for which manufacturers have 
invested in molds and other equipment that produce lettering of very 
precise sizes, NHTSA proposed exact conversions so that manufacturers 
would not have to buy new equipment. NHTSA also proposed exact 
conversions for gross vehicle weight rating (GVWR) measurements, speed 
measurements in Standard No. 110, Tire selection and rims, and weight 
load measurements in Standard No. 212, Windshield mounting and 
retention.
    The agency also sought comment on proposed metric conversions of 
consumer safety information in labels. Certain FMVSSs require labels 
that state consumer safety information in English measurements. NHTSA 
was uncertain whether labels with quantitative information stated 
solely in metric measurements would be understood by American 
consumers. Therefore, in those instances in which labels or other 
information are required for consumers' benefit, NHTSA proposed that 
both the English and metric units be provided. The labels for which 
dual measurements were proposed were those required by Std. No. 110, 
Tire selection and rims, Std. No. 120, Tire selection and rims for 
motor vehicles other than passenger cars, and Std. No. 126, Truck-
camper loading. NHTSA also stated its intent to eventually phase out 
the English measurements on those labels.
    Standards Nos. 207, Seating systems and 216, Roof crush resistance 
establish strength requirements for occupant seats and for the 
passenger compartment roof, respectively. The force measurements 
specified in the standards are straightforward enough when stated in 
English units, since both weight and force are expressed in pounds. 
However, the metric system expresses mass in kilograms and force in 
newtons. Consequently, when force pounds are converted to newtons, the 
force pounds should be multiplied by 4.448. Thus, in converting Stds. 
Nos. 207 and 216's English system force measurements to the metric 
system, NHTSA proposed to specify the steps of the conversion in the 
regulatory text to minimize the chance of a conversion error.
    NHTSA also announced that, in the future, it would convert values 
(expressed in English measurements) in documents incorporated by 
reference into the FMVSS, to the metric system, on a document-by-
document basis.

Public Comments on the NPRM and NHTSA's Responses

    In response to the NPRM, NHTSA received comments from 17 
commenters. The commenters generally favored the overall philosophy 
that NHTSA indicated it would follow in converting English measurements 
in the FMVSSs to metric measurements. Comments on specific English to 
metric conversions were offered.

1. ``Exact'' v. ``Equivalent'' Conversions

    In general, the commenters agreed with NHTSA's proposal to use 
equivalent, not exact, conversions. However, several commenters favored 
exact conversions. Flxible Corporation preferred exact conversions, 
explaining that making equivalent conversions in some instances and 
exact conversions in others could cause confusion. The National Truck 
Equipment Association (NTEA) stated that exact conversions should be 
used to eliminate the possibility of a standard's effectiveness being 
diminished. However, since neither Flxible nor NTEA cited specific 
instances in which making equivalent conversions instead of exact 
conversions would cause confusion or would lessen a standard's 
effectiveness, NHTSA is not adopting their recommendations.
    With respect to the conversion of some requirements, commenters 
favored exact conversions and sometimes provided reasons. Ford and 
Thomas Built Buses expressed a strong preference for the 10,000 lb. 
gross vehicle weight rating (GVWR) for vehicles to be converted to 4536 
kg. Thomas Built stated that the 36 kg. difference between the exact 
(4536 kg.) and equivalent (4500 kg.) conversions could determine 
whether many of their vehicles, particularly school buses, are subject 
to certain safety standards. Since vehicle GVWR seems to be an instance 
in which there would be a substantive change if exact conversions were 
not made in this final rule, NHTSA is (as proposed) converting GVWRs of 
10,000 lbs. to 4536 kg. and GVWRs of 6,000 lbs. to 2722 kg. 
[[Page 13641]] 
    Nissan stated that in Std. No. 104, Windshield wiping and washing 
systems, and Std. No. 216, Roof crush resistance, one inch should be 
converted to the exact value of 25.4 millimeters, not the equivalent 
value of 25 millimeters proposed in the NPRM. Nissan also stated that 
in S4. of Std. No. 216, the movement of the test device should be 
limited to 127 millimeters, not the 125 millimeters proposed in the 
NPRM. Since Nissan did not explain why the equivalent conversions 
proposed for Stds. Nos. 104 and 216 would make substantive changes, 
NHTSA is not adopting Nissan's suggestion to use the exact conversions.
    Volkswagen recommended that NHTSA's metric conversions be made in 
such a manner that they result in the same values as those in the 
comparable parts of the Canadian Motor Vehicle Safety Standards 
(CMVSS). As stated in the NPRM, NHTSA will make conversions in 
accordance with SAE guideline J916 May 1991, and Federal Standard 376B 
``Preferred Metric Units for General Use by the Federal Government.'' 
Where consistent with these two documents, and if the changes do not 
make substantive changes to the safety standards, NHTSA will make 
conversions consistent with the CMVSS.
    The National Institute for Standards and Technology (NIST) and Ford 
recommended that, to be consistent with the CMVSS, in Std. No. 110, 
Tire selection and rims, 60 mph be converted to the equivalent 
measurement of 100 km/h, not the exact measurement of 97 km/h proposed 
in the NPRM. However, Chrysler commented that there is a significant 
difference between 97 km/h and 100 km/h, and that therefore the exact 
conversion of 97 km/h should be used. Based on Chrysler's comment that 
there would be a substantive change in Std. No. 110 if an equivalent 
conversion of 100 km/h were adopted, NHTSA is converting 60 mph to 97 
km/h.

2. ``Mass'' v. ``Weight''

    Commenters noted that kilograms are measures of ``mass,'' not 
``weight.'' Thus, they recommended that all NPRM references to 
``weight'' be changed to ``mass.'' NHTSA acknowledges that commenters 
on this issue are technically correct. Thus, in instances in which the 
safety standards use ``weight'' to mean ``mass'' in describing 
compliance testing conditions and procedures, or in other instances in 
which the standards are primarily directed to engineers or other 
technically trained persons, NHTSA is revising ``weight'' in the 
regulatory text to ``mass.'' As an example, in a test specified in Std. 
No. 207, NHTSA proposed that the load applied be 20 times the 
``weight'' of the seat. In the final rule, Std. No. 207 is amended to 
refer to the ``mass'' of the seat.
    However, in instances in which the word ``weight'' is part of a 
term defined at 49 CFR part 571.3, such as ``curb weight,'' ``gross 
axle weight rating,'' ``gross vehicle weight rating,'' or ``unloaded 
vehicle weight,'' NHTSA is not making the change. In the NPRM, since 
NHTSA did not propose to amend the terms, adopting the terms ``curb 
mass,'' ``gross axle mass rating,'' or ``gross vehicle mass rating,'' 
is outside the scope of this rulemaking. NHTSA will consider amending 
these terms using ``mass'' in future rulemakings to metrify the safety 
standards.
    NHTSA is also concerned about the effect of changing from ``mass'' 
to ``weight.'' For example, it is not known whether the general public 
would be confused by use of the phrase ``Camper mass is ______ kg'' 
rather than ``Camper weight,'' specified in Std. No. 126. In addition, 
the States use terms such as gross vehicle ``weight'' rating as the 
basis for determining which vehicle registration fees, driver's 
licensing requirements, and restrictions on use of roads are applicable 
to particular vehicles. Before making a change from ``weight'' to 
``mass,'' NHTSA wants to obtain public comment and will propose any 
such changes in future metrication rulemakings.

3. Consumer Information

    In general, the commenters favored NHTSA's proposal to use dual 
English and metric measurements for information intended for consumers. 
Mr. Lawrence Stempnik noted that the technically correct abbreviations 
for units of measurement were not provided in Std. No. 126, Truck-
camper loading. The California Highway Patrol commented that the units 
of measurement are intended to provide safety information, not a 
``metric conversion educational program.'' NHTSA agrees that there 
should be no ambiguity in the metric units of measurement on labels 
that provide safety information to consumers. If unfamiliar terms are 
spelled out instead of abbreviated, there is less ambiguity and 
confusion. Thus, NHTSA is not adopting Mr. Stempnik's suggestion for 
the use of abbreviations, and is instead specifying the units of 
measurement as ``Liters'' and ``cubic meters,'' as proposed, rather 
than the abbreviations ``L'' and ``m\3\.''
    NIST recommended that dual labeling in English and metric units be 
required for only a limited time, but did not recommend a particular 
duration for that requirement. In the future, when consumers are 
familiar with metric measurements and there is no safety need for 
continuing to provide English measurements on labels, NHTSA expects to 
phase out the requirement for English measurements.
    Mack Trucks and the National Truck Equipment Association had 
recommendations for metric conversions of certification labels 
specified in 49 CFR parts 567 and 568. Since the NPRM did not propose 
changes to parts 567 or 568, these conversions are outside the scope of 
this rulemaking. However, NHTSA will take these comments into 
consideration during its review of parts 567 and 568 for conversion to 
metric measurements.

4. Force Measurements

    NHTSA proposed to convert force measurements in Std. No. 207, 
Seating systems, and Std. No. 216, Roof crush resistance, by specifying 
the steps of the conversion in the regulatory language. Except for the 
earlier discussed recommendation to specify ``mass'' instead of 
``weight,'' commenters generally agreed with NHTSA's proposal to 
specify force measurements in terms of kilograms multiplied by 9.8 to 
obtain newtons of force. For Stds. Nos. 207 and 216, NIST recommended 
that the kilograms be multiplied by 10 (rather than 9.8) to facilitate 
calculations of force. NIST's recommendation will not be adopted 
because NHTSA is not certain that use of a multiplier of 10 would not 
substantively change the stringency of tests specified in Stds. Nos. 
207 and 216.
    Thus, in the final rule, for Std. No. 207, NHTSA amends the force 
measurement language to provide that the seat shall be subjected to a 
force in newtons equal to 20 times the mass of the seat, measured in 
kilograms and multiplied by 9.8. For Std. No. 216, NHTSA amends the 
force measurement language to provide that the vehicle roof shall be 
subjected to a force in newtons equal to 1\1/2\ times the vehicle mass, 
measured in kilograms and multiplied by 9.8.

5. Use of Incorporated Documents

    In addressing whether values in incorporated documents should be 
converted, commenters urged NHTSA not to convert English measurements 
in outdated or superseded SAE Recommended Practices or standards, but 
to adopt the most recent SAE standards, which often specify metric 
measurements. NHTSA notes that the comments go beyond the scope of this 
rulemaking. Nevertheless, when NHTSA decides, on a document by document 
[[Page 13642]] basis, whether to convert incorporated documents to the 
metric system, it will consider these views.

Effective Date

    Chrysler recommended that the metrication changes take effect one 
year after issuance of the final rule. Chrysler stated that this lead 
time was necessary so that manufacturers could make the changes, taking 
into account that label manufacturers ``serve all of the vehicle 
manufacturers.'' NHTSA concurs that because this final rule will result 
in many manufacturers having to change labels, a one year lead time is 
appropriate. Thus, this final rule will take effect one year after it 
is published in the Federal Register. Manufacturers at their option, 
may comply with the amendments made by this final rule before the 
effective date.

Rulemaking Analyses and Notices

1. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This action was not reviewed under E. O. 12866, ``Regulatory 
Planning and Review.'' NHTSA has considered the impact of this 
rulemaking action under the Department of Transportation's regulatory 
policies and procedures and determined that it is not ``significant.'' 
In converting the Federal Motor Vehicle Safety Standards from the 
English to the metric system, the agency makes conversions that do not 
substantively change the performance requirements of the FMVSSs. In 
complying with this final rule, manufacturers providing consumer 
information (e.g., labeling) may incur one time, additional costs since 
they would have to change their information to add the metric units. 
However, the agency believes that the additional costs would be 
minuscule, since manufacturers already provide consumer information in 
English units.
    NHTSA determines that new labeling requirements in the following 
three standards would result in minor costs to manufacturers. For 
Standards Nos. 110 and 120, NHTSA estimates that changing the molds of 
non-pneumatic tires would initially cost $300,000 per year for the 
industry, or a few cents per tire. After the initial changes in the 
molds, further costs would be negligible. For Standard No. 120, NHTSA 
estimates that requiring the tire information label to have both 
English and metric units would increase costs by about one cent per 
motor vehicle, for vehicles other than passenger cars. The total cost 
to industry is approximately $62,000 for the 6.2 million vehicles sold 
in 1994. For Standard No. 126, since there are only 10,000 truck 
campers sold per year, changes to the truck-camper loading label will 
cost more than a few cents per label, but NHTSA estimates the total 
cost to industry will be less than $10,000 a year. In sum, NHTSA 
estimates that the total costs resulting from changes made by this 
final rule are $372,000.
    For these reasons, NHTSA determines the impacts of this action are 
so minor that a full regulatory evaluation for this final rule is not 
necessary.

2. Small Entity Impacts

    The agency has also considered the effects of this rulemaking 
action under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). I 
certify that this final rule would not have a significant economic 
impact on a substantial number of small entities. The rationale for 
this certification is that converting the FMVSS from the English system 
to the metric system does not make any substantive change to the 
performance requirements of any of the Federal Motor Vehicle Safety 
Standards. Manufacturers that qualify as small businesses that do not 
now label their products in metric units or provide consumer 
information in metric units will incur some slight costs to include 
metric units. However, the agency believes such costs would be minimal, 
given these manufacturers are currently labeling and providing the 
consumer information in English units.

3. Environmental Impacts

    In accordance with the National Environmental Policy Act of 1969, 
the agency has considered the environmental impacts of this rule and 
determined that, it will not have a significant impact on the quality 
of the human environment.

4. Federalism

    This action has been analyzed in accordance with the principles and 
criteria contained in Executive Order 12612, and it has been determined 
that the rule does not have sufficient federalism implications to 
warrant the preparation of a Federalism Assessment.

5. Civil Justice Reform

    This final rule will not have any retroactive effect. Under 49 
U.S.C. section 30103, whenever a Federal motor vehicle safety standard 
is in effect, a state may not adopt or maintain a safety standard 
applicable to the same aspect of performance which is not identical to 
the Federal standard. 49 U.S.C. section 30161 sets forth a procedure 
for judicial review of final rules establishing, amending or revoking 
Federal motor vehicle safety standards. That section does not require 
submission of a petition for reconsideration or other administrative 
proceedings before parties may file suit in court.

List of Subjects in 49 CFR Part 571
