TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of May 28, 1971, concerning the marking requirements in the proposed amendment to Standard No. 205, "Glazing Materials" (Docket No. 71-1; Notice 1). These requirements are only proposed at present, as is their effective date, and do not represent the agency's final decision on the matter. If the agency determines to amend the standard, and before any compliance with new requirements is required, a "final rule" will be issued that is based on the proposed rule but may differ in some respects from it. The final rule will specify an effective date for these new requirements which, in this instance, will probably be later than the effective date proposed.

You ask whether the effective date of the proposed standard would apply to the manufacture of the glazing, or to the fitting of the material into the vehicle. Standard No. 205 applies to "glazing materials for use in passenger cars, multipurpose passenger vehicles, motorcycles, trucks and buses", and the effective date of any amendment to this standard refers to the date of manufacture of the glazing material, and not to its fitting into the vehicle.

Your second question, whether we will accept your marking without a hyphen between the "DOT" symbol and your code mark, has been answered in our letter to you of May 26, 1971.

I hope this clarifies the situation.
