ASTM C 1349
ASTM C 1349 is a Standard Specification for Architectural Flat Glass Clad Polycarbonate. This specification was created by the American Society for Testing and Materials (ASTM). Founded in 1898, ASTM International is an international standards developing organization that develops and publishes standards for a wide range of materials, products, systems, and services. This specification deals with the quality requirements for cut sizes of glass clad polycarbonate (GCP). Polycarbonate is becoming more common in house wares as well as laboratories and in industry, especially in applications where any of its main features — high impact resistance, temperature resistance, optical properties—are required. In this regards, polycarbonate is useful regarding security, detention, hurricane/cyclic wind-resistant, and blast and ballistic-resistant glazing applications.
The main keywords to present this specification are: edge compression; flat glass; heat-strengthened glass; heat-treated glass; surface compression; tempered glass.
