Dear Mr. Katz: This responds to your February 1, 1977, letter requesting informatio concerning the Federal regulations that would be applicable to glazing for use in van-type vehicles. Your assumption that the glazing regulation is not applicable to plastic material used for porthole windows and sun-roofs in vans is incorrect.; Federal Motor Vehicle Safety Standard No. 205, *Glazing Materials*, 4 CFR 571.205, specifies requirements for all glazing materials for use in motor vehicles and motor vehicle equipment. The standard specifies the types of glazing that may be used in various locations in vehicles and, in addition, specifies performance requirements for each type of glazing. Although the standard does permit the use of plastic glazing in side windows and sun-roofs of van-type vehicles, the plastic glazing must meet specified performance requirements.; I am enclosing a copy of Standard No. 205 (and the ANS Z26 standar that is incorporated by reference in Standard No. 205) for your information. From the standard you will be able to determine the various types of glazing that may be used for side windows and sun-roofs in vans.; Sincerely, Frank Berndt, Acting Chief Counsel
