TITLE: FMVSR INTERPRETATION

TEXT: This responds to your March 30, 1977, letter asking whether the rebuilding of a motor vehicle with all new running gear and an old body constitutes the manufacture of a new motor vehicle requiring compliance with Federal regulations.

In the rebuilding operation you describe, you retain the old body tank structure while replacing the entire running gear assembly. The National Highway Traffic Safety Administration (NHTSA) has determined by regulation in 49 CFR 571.7(f) that the rebuilding of a motor vehicle using old running gear with a new body does not constitute the manufacture of a new motor vehicle. The vehicle will be considered newly manufactured unless, at a minimum, the trailer running gear assembly is not new and was taken from an existing trailer whose identity is continued with respect to the Vehicle Identification Number. In addition, the trailer must be owned or leased by the same party both before and after the remanufacture. Since the running gear with which you plan to equip your vehicle is new, your operation constitutes the new manufacture of a vehicle.

You ask secondly what portion of the running gear can be replaced as normal repairs without such replacement being considered the manufacture of a new vehicle. You may replace any part of the running gear assembly that breaks or malfunctions during operation of the motor vehicle. The NHTSA would consider this to be normal maintenance of the vehicle, not subject to the requirements applicable to vehicle manufacture.

Attention: Legal Counsel

We are manufacturers of tank type truck bodies and trailers with running gear.

On a somewhat irregular basis, we receive requests from users of this equipment to perform certain repairs.

Our specific question at this time relates to repairs done to the running gear of trailers and whether an involvement with 49CFR 571.7(f) concerning new and used components is incurred.

1. If the present tank structure and upper fifth wheel coupler are reused in conjunction with a totally new running gear assembly, is the vehicle still a used vehicle for the purpose of the applicability ruling regarding conformance to federal regulations?

2. If the preceding answer is no, what portion of the running gear - wheels, axles, brakes and suspension - can be replaced as normal repairs without changing the status to "new"?

For the purpose of this inquiry the vehicle identification is continued and ownership is retained.

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of July 11 in which you asked what standards will be applied to stop and turn signal lamps after September 1, 1974.

Parking, stop, and turn signal lamps are required by Section S4.1.1.11 and S4.1.1.12 to meet the grouped photometric minimum candlepower requirements specified in Figure 1 of FMVSS No. 108. Prior to September 1, 1974, multiple compartment or multiple lamps need only meet the group value total specified in Figure 1 for a single compartment or single lamp. After that date, however, the higher candlepower values for two and three compartments or lamps specified in Figure 1 are applicable.

Docket 69-19; Notice 3, published in the Federal Register on October 25, 1972, only proposed that SAE (Illegible Word) and (Illegible Word) be referenced in FMVSS No. 108. Until such time as Standard 108 is further amended, SAE J586b, June 1966, and J588d, June 1966, are applicable to stop lamps and turn signal lamps, respectively.

If the new revisions to the SAE standards are included as an amendment to Standard 108, sufficient lead time will be provided to allow the manufacturers to make any changes necessary to meet the new requirements.

Re: A lamp with two or three lighted compartments used in Stop Lamp and Turn Signal Lamp.

Dear Mr. Driver

According to S 4.1.1.12 in MVSS No. 108 a lamp with two or three lighted compartment is required to meet the minimum photometoric values at each test point specified in table 2 of SAE Standard J575d.

However, after September 1, 1974 a Stop Lamp has to be complied with SAE J586c by P.R. dated October 25, 1972 and SAE J508e for Turn Signal Lamp and further the standards of a lamp with two or three lighted compartments will be applied to a lamp with two or three lighted compartments and by F.R. dated April 9, 1974 the F.R. dated October 25, 1972 has been postponed.

Please let us know what standards will be applied to Stop, Turn Signal Lamp after September 1, 1974, the standards as they are now or the proposal as it is being planned will become effective.

Thanking you in advance for your cooperation,

This responds to your February 19, 1986 letter to the National Highway Traffic Safety Administration (NHTSA) asking whether Federal motor vehicle safety standards prohibit commercial businesses from using fiberglass on the exterior of school buses. As explained below, the answer to your question is no.

The National Traffic and Motor Vehicle Safety Act authorizes NHTSA to issue minimum performance standards for school buses. Our safety standards do not specify the materials to be used for the exterior of school buses. However, the materials chosen by a manufacturer must be strong enough to enable the bus to meet the requirements of those standards. Among those requirements are the rollover protection ones of Standard No. 220, fuel system requirements of Standard No. 301, and strength requirements of Standard No. 221, School Bus Body Joint Strength, for body panel joints on school buses with gross vehicle weight ratings over 10,000 pounds. Manufacturers of new school buses using fiberglass for school bus exteriors must certify that their vehicles conform to the requirements of all applicable school bus safety standards.

I hope this information is helpful. Please contact my office if you have further questions.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Ms. Holm,

We have discovered the presence of fiber glass in the outer skin of the Van Conversions manufactured by the Collins Industries Inc. of Hutchinson, Kansas. While, admittedly, we see little if any, safety hazard associated with the practice, we do forsee the possibility of legal actions "down the road" if children are seriously injured and the presence of this material is exposed.

Our school bus specifications require compliance with the National Minimum School Bus Standards as well as all Federal Motor Vehicle Safety Standards applicable to the manufacture, sale and operation of pupil transportation equipment. My question is: Does the use of fiberglass in the manufacture of Type II school buses conflict with any known FMVSS?

An early response will be appreciated.

Dear Dr. Sackoff:

This responds to your letter to this agency with reference to Federal Motor Vehicle Safety Standard No. 109, New Pneumatic Tires.

Your specific question addressed S4.2.2.4, Tire strength, which states: "Each tire shall meet the requirements for minimum breaking energy specified in Table I when tested in accordance with S5.3." You asked for an interpretation of the term "breaking," whether it means a blowout of the tire or the breaking of the tire caused by the plunger used in the test specified in the standard.

The breaking energy test is a measure of the resistance of the tire to bruise or damage due to impact of the tire with road hazards. This agency tests such resistance in accordance with the procedures of S5.3, Tire strength, of the standard. In that test, a cylindrical steel plunger is forced perpendicularly into the tire rib at the rate of 2 inches per minute at five test points equally spaced around the circumference of the tire. The inch-pounds of force required to push the plunger into the tire is continuously monitored. As the plunger pushes into the tire, the resistance to the plunger force increases. That resistance requires ever- increasing force applied to the plunger to continue pushing it into the tire. Ultimately, one of two things will happen:

1. The plunger will push all the way to the rim; or

2. The tire cords, plies, innerliner, or other components of the tire will stretch, separate, crack or break so that the resistance pressure of the tire diminishes. The "breaking" of the tire at that point does not require an actual blow-out although, obviously, a blow-out would constitute a "breaking."

The plunger force is measured just prior to contact with the rim as in 1 above or just prior to the force reduction described in 2 above. The measured force is then combined with the penetration of the plunger into the tire as specified in S5.3.2.3 and S5.3.2.4 of the standard. The breaking energy value of the tire is then determined by computing the average of the values obtained at the five test locations on the tire. Table I, Appendix A of the standard specifies the minimum breaking energy of tires based on tire type, size, composition, and inflation pressure.

I hope this information is helpful to you. Should you have any further questions or need any additional information, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992.

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of September 8, 1971, in which you request clarification of Motor Vehicle Safety Standard No. 202, "Head Restraints". You state that you are of the opinion that "a head restraint system that can be retracted into the seat and thus made ineffective by virtue of being adjustable is in conflict with the prime object of the standard in reducing the frequency and severity of neck injuries in rear end or other collisons."

Standard No. 202 does not prohibit head restraints from being adjustable in an up-and-down direction, as long as the top of the restraint, at its fully extended design adjustment position, is at least 27.5 inches above the seating reference point (S4(b)(1)). While some of these adjustable head restraints may not be completely effective in cases where they are placed at their lowest adjustment position and used by tall drivers, we have determined that this design, as long as it meets the requirements of the standard, is a minimum performance level that meets the need for motor vehicle safety. Consequently, use of these types of restraints does not conflict with the standard.

The standard establishes only a minimum performance level, however, and the NHTSA endorces efforts by manufacturers to exceed the

2 requirements is establishes. Many manufacturers have installed head restraints in their vehicles that meet the standard's requirements yet do not present the disadvantages you describe.

We are pleased to be of assistance.

ASTON MARTIN LAGONDA LIMITED

Douglas W. Toms, National Highway Traffic Safety Administrator, National Highway Traffic Administration,

As designers and manufacturers of the Aston Martin DBS V8 car, currently being marketed in U.S.A., we are concerned at what appears to be a very loose interpretation of Motor Vehicle Safety Standard No. 202, Head Restraints - Passenger Cars, Section 5.4(b), adopted by certain American automobile manufacturers.

Aston Martin Lagonda have been concerned for many years with primary and secondary safety aspects of the car, and we hold the view that a head restraint system that can be retracted into the seat and thus made ineffective by virtue of being adjustable, is in conflict with the prime object of the Standard in reducing the frequency and severity of neck injuries in rear end or other collisions.

We would appreciate clarification on this point, for our concern is to maintain the highest standard of interior safety as exemplified by our current production car.

Dear Mr. Rhein:

This responds to your letter about the consumer registration card required by Safety Standard No. 213, "Child Restraint Systems." I apologize for the delay in responding.

You ask about three features of a registration card you wish to produce, and enclosed a sample card setting forth a "proposed format." You first ask whether you may specify "Please Print" on the card. The answer is yes. NHTSA interpreted Standard 213 as permitting this feature, in an October 20, 1993 letter to Mr. Richard Glover of the Evenflo Juvenile Furniture Company.

You also ask whether you may use "open box spaces" for the consumer's name and address, to encourage consumers to print the information clearer (one character per box space). The answer is yes. NHTSA interpreted Standard 213 as permitting "blocked squares" for the consumer's name and address in a June 14, 1993 notice (copy enclosed) denying Evenflo's petition for reconsideration of the rule that established the registration card requirement.

Finally, you ask whether you may enlarge the consumer name and address space of the card, to provide consumers more space to print the information and thus increase the likelihood the information will be legible. The answer, with reference to the sample card you provided, is yes. Under S5.8 of Standard 213, the registration form must conform in size, content and format to forms depicted in the standard (figures 9a and 9b). The figures specify a minimum size for the card. Moreover, in the enclosed June 1993 notice, NHTSA explained that "(f)ormat refers to the general appearance of the form and to aspects such as type size, size and placement of margins, size and placement of the spaces for the consumer's name and address, and overall organization of the printed material."

The sample card you provided meets the minimum size requirement specified in the standard, and the general appearance and overall organization of the card is the same as that depicted in the standard (figure 9a). While the consumer name and address space is slightly larger than depicted in the standard, we conclude that this slight deviation is consistent with the standard's format requirements. This conclusion is based on the fact that this slight change does not affect the general appearance or overall organization of the card, and because the change provides consumers more space to print the information, i.e., it will not detract from the utility of the card.

Please contact Ms. Deirdre Fujita of my staff at (202) 366-2992 if you have any questions.

This is in response to your letter of May 25, 1984, asking for an interpretation of Motor Vehicle Safety Standard No. 108. Table IV specifies that the minimum horizontal separation distance "(centerline to centerline of lamp)" for rear turn signal lamps on motorcycles is 9 inches. You have asked whether the "centerline" refers to the distance between the lens centers, between the centers of the effective projected luminous areas, or between the bulb centers.

You asked for confirmation of your belief that the proper interpretation is found in the referenced SAE Standard, J588e, which contains the language "Optical axes (filament centers)," implying that the correct distance is that between the "bulb centers" as you term it.

We find no direct correlation between the phrases "centerline to centerline of lamps" and "optical axis (filament center) ." The lamp is a device emitting light whereas "optical axis (filament center)" does not refer to the lamp but only to a portion of its light-producing component. As that phrase is used in SAE J588e, it defines the method of measuring distances between bulbs in multi-compartment lamps for the purpose of testing for photometric requirements (paragraph 3.1), or in measuring the separation of the turn signal from the headlamp (paragraph 4.2, where, incidentally, it is expressed as the distance between filament and a lamp component, the retaining ring).

Taken literally, "centerline to centerline of lamps" in our view means the distance between lens centers. In the response to petitions for reconsideration of the center high-mounted stoplamp amendment (May 17, 1984), the question was asked whether the "center" of the lamp was its geometric center, its optical center, or the center of the bulb filament. The agency replied that the center of the lamp is the geometric center. Since the purpose of the minimum separation requirement is to insure that the turn signal is perceived as such, we believe that the correct interpretation of "centerline to centerline" is a measurement from the geometric center of one lamp to the geometric center of the other lamp. The geometric center would be anonymous with the term "geometric centroid of lens" as used in SAE J1221 Headlamp-Turn Signal Spacing. Sincerely,

Frank Berndt Chief Counsel

Dear Mr. Hilgendorf: Mr. Frank Coy, Special Assistant to the Under Secretary o Transportation has asked that I respond to your letter of April 16, 1969, in which you ask whether a station wagon purchased in March of 1968, equipped with two ply tires, violates Federal Motor Vehicle Safety Standard No. 109.; The vehicle you purchased was apparently manufactured prior to April 1 1968, and therefore, it was not required to be equipped with tires conforming to Standard No. 109. However, even if the standards were applicable, because a tire is labeled '2-ply' it is not necessarily a non-conforming tire. Standard No. 109 does not specifically require tires to have a given number of plies. It does require that irrespective of any ply rating tires pass minimum performance tests. As to passenger cars, Standard No. 110 requires that passenger cars manufactured after April 1, 1968, (1) must be equipped with tires that comply with Standard No. 109, and (2) the vehicle must not place a load on any of the tires greater than the load capacity of the tire specified in Standard No. 109.; Very truly yours, Howard A.

Dear Mr. Coffey: This is in response to your request for information concerning method of ensuring the compliance of school buses with the barrier crash test requirements of Federal Motor Vehicle Safety Standard No. 301-75, *Fuel System Integrity*.; Standard No. 301-75, while establishing minimum performance levels does not specify any particular design requirements for school bus fuel systems. A manufacturer is free to design his vehicles in the manner that he believes most appropriate to ensure compliance. To this end, you may find helpful information in a study by Dynamic Science entitled *School Bus Safety Improvement Program*. The NHTSA cannot assure you, however, that following the suggestions contained in the study will guarantee that your school buses will comply with the standard.; The study is filed in the NHTSA's public docket as document numbe 75-03-GR1.

Dear Mr. Iwase: This is to provide you with a clarification of m letter to you dated March l6, l988. Your second question was whether the minimum edge to edge separation distance between turn signal lamps and tail/stop lamps is required on a rear lighting array for motorcycles. I responded that 'The answer is yes, and the separation distance you have depicted in your drawings appears to comply with this requirement.' In actuality, the agency has required this separation only where a single motorcycle stoplamp/taillamp is mounted on the vertical centerline, and not when dual lamps are mounted on either side of the vertical centerline, the configuration depicted in your letter of January 25, 1988. Therefore, I am advising you that there is no legal requirement that the 4-inch separation distance be maintained in the configurations you depicted, and that we appreciate your continuing efforts to understand and comply with Federal Motor Vehicle Safety Standard No. 108. I enclose a copy of a letter from this Office dated November 2l, l984, which explains our views on motorcycle rear lighting configurations in more detail. Sincerely, Erika Z.
