ASTM C 1349
is a Standard
Practice Standard Specification for Architectural Flat Glass Clad Polycarbonate. This standard was created by the American Standard for Testing and Materials (ASTM). ASTM International
which was funded in 1898, is an international standards developing organization that develops and publishes standards for a wide range of materials, products, systems, and services. This standard 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 standard are: edge compression; flat glass; heat-strengthened glass; heat-treated glass; surface compression; tempered glass.
