TITLE: FMVSS INTERPRETATION

TEXT: This responds to your July 24, 1981, letter directed to our Office of Enforcement in which you ask whether it would be permissible to test for compliance with Standard No. 302, Flammability of Interior Materials, in a manner different than that prescribed in the standard. The standard states that a 14-inch long section of material shall be burned in a test oven until the flame reaches within 1 1/2 inches from the end of the material. You state that for some fabrics this requires a test that can extend to 10 minutes. In a test of this length, the heat buildup in the test oven can cause the glass front of the oven to break. You suggest that the test be discontinued after five minutes, and the burn rate calculated.

The test requirements of the standard are provided to show how the agency will test for compliance. However, it is not compulsory that a manufacturer adhere to every facet of the test procedures if it can satisfy itself that its product will comply with the standard by testing in another manner.

As you know, the standard requires only that the burn rate of a material not exceed four inches per minute. A 14-inch long section of material that has not burned completely to its end in five minutes obviously would not exceed the 4-inch per minute burn rate. Accordingly, we do not see any reason that you could not terminate the test five minutes after the starting point specified in paragraph S5.3(e) of the standard.

Enforcement Director:

Our laboratory has been conducting tests for conformance to FMVSS 302 for many years. In the last couple of years we have noticed that certain materials although very slow burning create so much heat within the chamber that the heat resistant glass on the front of the cabinet shattered.

If one stays in strict compliance with the test procedure, the material being tested must be allowed to burn for a distance of 10 inches in the timing zone. In order to prevent excessive heat build up with possible harmful side effects, it might be suggested to abort the testing after 5 minutes of timing and calculate the burn rate on the length burned in 5 minutes.

Since this is not incorporated in any part of the test procedure, may we ask for your opinion in this regard.

Although we are highly concerned for the safety of our technical help and take all necessary precautions, we feel that the suggested approach should be either spelled out in future revisions or that a statement be issued by the Department of Transportation with regard to this problem.

TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of February 18, 1976, concerning testing procedures pursuant to Federal Motor Vehicle Safety Standard No. 302, Flammability of Interior Materials.

As you point out, S5.1.3 of the standard provides that thin, heat resistant wires are used to support a "specimen that softens and bends at the flaming end so as to cause erratic burning." One of your customers asserted that support wires should be used in testing his materials, and you have asked when the use of support wires is appropriate.

Your interpretation of the standard in this case is commendable, and your test practices are calculated to demonstrate clearly the exercise of due care that a particular product complies with Federal motor vehicle safety standards. However, an NHTSA July 19, 1971, interpretation of Standard No. 302 (copy enclosed) permits use of support wires when any bending of the tested material occurs. At the time of that interpretation, it was believed that the support wires would not influence the test results.

More recent testing by the agency demonstrates that the support wires do significantly affect burn rates, and the agency intends to issue an interpretative amendment of the standard that will limit use of support wires.

Thank you for your responsible approach to testing products that are required to conform to Federal motor vehicle safety standards.

Office of Chief Counsel National Highway Traffic Safety Administration

We are an independent testing laboratory, whose services include conducting the tests for flammability, including the Motor Vehicle Safety Standard No. 302. A question concerning the test procedure and method has been brought to our attention and we need an official interpretation.

The test method states, "A specimen that softens and bends at the flaming end so as to cause erratic burning is kept horizontal by supports consisting of thin, heat-resistant wires, spanning the width of the u-shaped frame under the specimen at 1-inch intervals". We have always interpreted this statement to mean that if the material would have a tendency to become almost vertical upon ignition you would support the material with the wires, otherwise the wires would not be needed; as an example, a specimen of plastic or a headlining material would be supported by the wires. A large percentage of our testing is on materials related to carpeting, either woven or tufted, and we do not use the wires for support since the material does not have a tendency to become vertical during the test.

A manufacturer has sent us some material which is to be used as an upholstery fabric and asked us to conduct the test No. 302. We conducted the test according to the procedure; however, we did not use the support wires on this material as we felt the material was not covered under the above statement. The material was cut into four specimens, two specimens in the machine direction and two specimens in the "cross-machine" direction. Two specimens are tested with the "face up" in both directions and two specimens are tested with "face-down" in both directions, as we cannot determine prior to the test which will give us the most adverse results (para. S5.2.2). The material failed the test. We are enclosing a copy of the test results with the manufacturers name blotted out.

When the manufacturer received the report, he was quite upset, as a copy of his letter to us shows. The material, according to him, should be tested using the support wires which in this case allows the material to pass the test; however, if the support wires are not used, the material will almost always fail the test. We have told him that we do not conduct the test so that the results would always be beneficial to the manufacturer, but that we conduct the test in accordance with the standard and our interpretation of the test method which in some cases is not beneficial to the manufacturer. It is our opinion that flammability tests are not conducted in such a way as to suit a manufacturer because he wants a passing report, but that the test should be conducted under the most adverse conditions so as to give a true look at the material being tested.

I am enclosing a piece of the material in question and hope to have a ruling as soon as possible as to whether or not support wires should be used with this material. We have other tests to perform which we are holding until we hear from you.

TEXT: Dear Mr. Thies:

This responds to your letter asking about Federal rules, particularly those for flammability resistance, applicable to your aftermarket product. I apologize for the delay in responding. You state that your product is a sheet of clear vinyl that inhibit s the air flow in a van, thus reducing the amount of air to be heated or cooled. You further state that your product does not impair visibility and that it is easily detached and removed by the vehicle owner. This response is based on our understanding of the facts presented in your letter.

By way of background information, NHTSA is authorized to issue Federal Motor Vehicle Safety Standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. Instead, the National Traffic and Motor Vehicle Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The agency periodically tests new vehicles and items of equipment for compliance with the standards.

In response to your question, you are required to certify that your device complies with Standard No. 205, Glazing Materials (49 CFR @ 571.205), based on our understanding of your letter. Standard No. 205 applies to new, completed vehicles as well as to glazing sold in the aftermarket. The standard establishes performance requirements for various types of glazing (called "items") and specifies the locations in vehicles in which each item of glazing may be used. The standard also incorporates by refer ence "ANSI Z26," the American National Standards Institute's "Safety Code for Safety Glazing Materials for Motor Vehicles Operating on Land Highways." It appears that your device may be considered an "interior partition," which is considered under ANSI Z 26 to be item 6 glazing.

In addition, if your product were manufactured for a new vehicle, the vehicle would have to be certified as complying

2

with Standard No. 111, Rearview Mirrors and Standard No. 302, Flammability of Interior Materials, in addition to Standard No. 205. However, Standards No. 111 and No. 302 apply only to new vehicles, and not to items of aftermarket motor vehicle equipment . Thus, they do not apply to your product.

I note, however, that there are other Federal requirements that indirectly affect the manufacture and sale of your product. Under the Safety Act, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle eq uipment, you are subject to the requirements in @@ 151-159 of the Safety Act concerning the recall and remedy of products with safety related defects. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your product contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

Manufacturers, distributors, dealers, and motor vehicle repair businesses are subject to @ 108(a)(2)(A) of the Safety Act, which states: "No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative . . . any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard . . . ." Your vinyl sheet could render inoperative the rearward visibility requiremen ts set forth in Standard No. 111, or the light transmittance requirements set forth in Standard No. 205. In addition, your product could have elements of design that could render inoperative a vehicle's compliance with Standard No. 302, the FMVSS for fl ammability resistance for materials used in the occupant compartment of motor vehicles. While it appears unlikely that persons in the aforementioned categories would be installing your product, if they were to install it, they not compromise the rearwar d visibility or flammability resistance provided by the motor vehicle.

The "render inoperative" prohibition of @ 108(a)(2)(A) does not apply to the actions of vehicle owners in adding to or otherwise modifying their vehicles or items of motor vehicle equipment. Thus, if your products were placed in vehicles by the vehicle owners, they would not need to meet any FMVSSs. Nevertheless, NHTSA urges vehicle owners not to tamper with or degrade the safety of their vehicles.

Dear Ms. Jones:

This responds to your letter to Ms. Deirdre Fujita of my staff asking about safety regulations, particularly for flammability resistance, for a device you call a "Toddler Traveler pillow." According to promotional literature you sent with your letter, the Toddler Traveler pillow is used with a child booster seat to provide "padded comfort and support" to a child sleeping in the booster. The pillow provides a surface the child could lean on while sleeping.

By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the authority to issue Federal motor vehicle safety standards (FMVSSs) for new motor vehicles and new items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. Instead, Congress has established a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the information set forth in your letter and promotional literature.

Currently there are no Federal motor vehicle safety standards (FMVSSs) that directly apply to the Toddler Traveler pillow. Our standard for "child restraint systems," FMVSS 213, applies to "any device except Type I or Type II seat belts, designed for use in a motor vehicle or aircraft to restrain, seat, or position children who weigh 50 pounds or less." The standard does not apply to accessory items, such as a pillow that is used with a child booster seat. Our standard for flammability resistance, FMVSS 302, applies to new motor vehicles and to new child restraint systems. It does not apply to child restraint accessory items.

While no FMVSS applies to the Toddler Traveler pillow, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you

are subject to the requirements of 49 U.S.C. ''30118- 30121 concerning the recall and remedy of products with safety related defects. I have enclosed a copy of those defect provisions, as well as an information sheet that briefly describes those and other manufacturer responsibilities. In the event you or NHTSA determines that your product contains a safety- related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

In addition, while it is unlikely that the Toddler Traveler pillow would be installed by a motor vehicle manufacturer, distributor, dealer or repair business, 49 U.S.C. '30122 prohibits those businesses from installing the device if the installation "makes inoperative" compliance with any safety standard. No commercial business listed in '30122 can install a Toddler Traveler pillow if the product undermines the vehicle's compliance with a safety standard, including Standard 302 for flammability resistance.

The prohibition of '30122 does not apply to individual owners who install equipment in their own vehicles. Thus, individual owners may install any item of motor vehicle equipment regardless of its effect on compliance with Federal motor vehicle safety standards. However, NHTSA encourages vehicle owners not to degrade the safety of their vehicles.

Before closing, we would like to comment on a further issue, one that you and Ms. Fujita discussed on the telephone. The advertising literature you enclosed with your letter described the Toddler Traveler pillow as being suitable for use with children ages "18 months to 4 years." We believe this description is potentially confusing concerning the use of booster seats by young children. Booster seats are intended to be used as a transition to safety belts by older children who have outgrown convertible seats (ideally, over 40 pounds and 4 years). A booster seat is not designed to restrain young children, and under a requirement we recently adopted, cannot now be recommended for children under 30 pounds. Stating "18 months to 4 years" may be mistaken to imply that, with your pillow, a booster seat could be used to restrain a child as young as 18 months. To avoid any possible misunderstanding, we suggest that the phrase on recommended use of the pillow should refer to older children, such as those "over 4 years."

One further note in closing. You said that a year ago, Ms. Fujita told you "there are no codes to govern" your product. Ms. Fujita is concerned that you might believe you were given an oral interpretation of how our requirements apply to your product. Please note that we cannot give oral interpretations. Ms. Fujita provided you a copy of an interpretation we'd issued in the past on a child seat pillow accessory, while indicating that an interpretation of which requirements apply to your product must be from us in writing. (This letter comprises that interpretation.) We regret any confusion on this issue.

I hope this information is helpful. If you have any other questions, please feel free to contact Ms. Fujita at (202) 366-2992.

TEXT: This is in response to your letter of March 31, 1975, in which you recommended a modification of the testing procedures pursuant to Standard No. 302, Flammability of Interior Materials. Your modification would require the presence of support wires in all tests. After consideration of the recently-complied test data on the use of support wires in the testing procedures, the NHTSA has decided that modification of the standard should be considered along the lines you suggest.

The NHTSA has interpreted Standard No. 302 to permit the use of support wires when any bending of the tested material occurred. At the time of that interpretation, it was believed that support wires would not influence the test results. More recent testing by the agency indicates that the use of support wires does significantly affect burn rates. For this reason, the agency is considering various possibilities in addition to the one you suggest.

Mr. Patrick J. Tyler Englander 3429 West 47th Street Chicago, Illinois 60632 Dear Mr. Tyler:

This responds to your September 8, 1982, letter asking whether a mattress that you manufacture for use in a truck cab would be required to comply with Standard No. 302. Flammability of Interior Materials.

Standard No. 302 lists the components that are covered by the standard. That list states that mattress covers must comply with the standard's requirements. The agency has interpreted the mattress cover language to mean both mattress covers and the permanent mattress ticking. Accordingly, your mattress to the extent that it is designed for use in new vehicles must comply with the requirements.

You should be aware that nothing prohibits a vehicle owner from purchasing noncomplying equipment as replacement equipment if he so chooses. You did not indicate whether your operation is for new vehicles or replacement equipment. In the instance of noncomplying replacement equipment, no manufacturer, repair business, or distributor could install such noncomplying equipment. The installation would have to be made by the vehicle owner himself. Sincerely,
