This responds to your letter dated March 27, 1984 regarding Federal Motor Vehicle Safety Standard No. 107 Reflecting Surfaces in which you ask for an interpretation of the term "bright metal components." You asked whether these components would include only polished metal or plated components and not painted metal components, even if painted "a shiny high gloss black." In addition, you asked whether a plastic component would be covered by the standard.

The purpose of Standard No. 107 is to reduce the likelihood that unacceptable glare from reflecting surfaces in the driver's field of view will hinder safe and normal operation of the motor vehicle. The standard sets limits on the "specular gloss of the surface of the materials" used for certain "bright metal components." The standard was based on materials commonly used in vehicle at the time of the standard issuance and thus it referred to metal components. Since the requirements apply to the surfaces of those metal components, a metal interior rearview mirror frame with a painted "shiny high glass" surface would be covered by the standard.

An all-plastic component would be outside the literal requirements of the standard. But since a plastic component could produce an unacceptable glare if located in the driver's field of view, the agency urges manufacturers to use plastic materials which will not produce glare.

Sincerely,

Frank Berndt Chief Counsel

Dear Mr. Berndt:

I am writing you to reference to Motor Vehicle Safety Standard Number 107-Reflecting Surfaces. The standard specifies the specular gloss of the surface of the materials used for specified " . . . bright metal components in the driver's field of view . . polished metal or plated components and not to painted components. Thus, an inside rearview mirror frame and bracket, for example, painted black would not be subject to the requirements of the standard even if it were painted a shiny high gloss black. Likewise, a plastic component would not be subject to the standards requirements unless it was bright metal plated such as being chrome plated.

We request your confirmation of our interpretation and thank you in advance for your prompt reply.

Very truly yours,

Thomas D. Turner Manager, Engineering Services fvc c: David James FMVSS 107 File
