Dear Mr. Henderson: This responds to your letter concerning the edge treatment requirements of Safety Standard No. 205, *Glazing Materials*, as they would apply to rigid or flexible plastics to be used for windshields on motorcycles. You asked for confirmation that one-piece plastics are required to meet the edge treatment requirements set forth in the standard for non- laminated glass.; The edge treatment requirements of Standard No. 205 are specified i paragraph S5.2, which incorporates by reference the SAE Recommended Practice J673a, Automotive Glazing,' August 1967. The SAE Practice specifies different requirements for tempered' and laminated' safety glass. The agency interprets the distinctions to apply equally to plastics. Therefore, one-piece plastic materials must meet the edge treatment requirements specified for tempered' glazing, and laminated plastics must meet the requirements specified for laminated' glazing.; Please contact this office if you have any further questions. Sincerely, Joseph J. Levin, Jr., Chief Counsel
