Dear Mr. Yeoman: This is in reply to your letter of October 16, 1972, requesting a DO number for safety glazing materials. You indicate that your understanding is that such a number is required in order to obtain approval under ANS Z26.1-1966.; Under Federal Standards applicable to motor vehicle glazing material (Motor Vehicle Safety Standard No. 205, 49 CFR 571.205) the manufacturer of the material is responsible for certifying the conformity of the material to the standard. The NHTSA does not provide prior approvals, but tests materials it purchases on the open market. Motor Vehicle Safety Standard 205 incorporates by reference, with some exceptions, ANS Standard Z26.1-1966. The DOT number to which you refer has been an optional method by which prime glazing material manufacturers certify their materials. Beginning April 1, 1973, prime glazing material manufacturers will be required to use the symbol DOT and a code number in certifying their materials. Plaskolite Incorporated is hereby assigned code number 98. The method for certifying is more fully explained in the Standard.; While the NHTSA does not require prior approvals of glazing materials such approvals are required by certain States. You may obtain information regarding these approvals from the American Association of Motor Vehicle Administrators, Suite 500, 1828 L Street, N.W., Washington, D.C. 20036.; Sincerely, Robert L. Carter, Associate Administrator, Motor Vehicl Programs;
