TITLE: FMVSS INTERPRETATION
TEXT: This is in reply to your letter of March 26, 1971, concerning regulations pertaining to automobile windshields.
Federal Motor Vehicle Safety Standard No. 205, Glazing Materials, Passenger Cars, Multipurpose Passenger Vehicles, Motorcycles, Trucks and Buses, a copy of which is enclosed, specifies the requirements of automotive glazing materials manufactured on or after January 1, 1963. ANSI Standard Z26.1-1966, incorporated by reference, can be obtained from the American National Standards Institute, 1430 Broadway, New York, New York 10013, at a cost of $ 4.00.
The marking of the windshield that you depict in your letter of March 26 is not sufficient to identify its manufacturer. However, based on the "63" in the marking and the fact that the windshield shape fit the 1969 Plymouth, it can be hypothesized that the material in question is a laminated windshield of the improved design that has been used in 1966 and later models of U.S. automobiles.
There is not a requirement that windshields of this type completely shatter leaving no jagged fragments upon collison.
Sincerely,
