Standard Specification for Architectural Flat Glass Clad Polycarbonate
|Publication Date:||15 April 2017|
|ICS Code (Films and sheets):||83.140.10|
1.1 This specification covers the quality requirements for cut sizes of glass clad polycarbonate (GCP) for use in buildings as security, detention, hurricane/cyclic wind-resistant, blast and ballistic-resistant glazing applications.
1.2 Optical distortion and the evaluation thereof are not currently within the scope of the standard. Mockups are recommended as a method to evaluate glass. (See Appendix X3.)
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.View Less
