This specification covers the quality requirements for cut sizes of architectural flat glass clad polycarbonate (GCP) for use in buildings as security, detention, hurricane/cyclic wind-resistant, and blast and ballistic-resistant glazing applications. Architectural polycarbonates furnished under this specification shall be of the following kinds: Kind GCP, single core (SC); Kind GCP, multiple core (MC); and Kind GCP, others (O). The polycarbonates shall be examined by means of the following: security test; impact test for safety glazing; missile impact and cyclic pressure test; security glazing test; airblast loading test; detention glazing test; bullet resisting glazing test; burglary resisting test; visual inspection; and transmittance test. The materials shall also adhere to specified size and dimensional requirements, and maximum allowable blemishes in form of bubbles, edge boil blow-ins, fuses, single strand lint hairs, inside dirt spots, areas of concentrated lint, delamination and discoloration, short interlayer and unlaminated area chips, streaks and scuffs, white scratches, carbon specks, and crizzles.
