ASTM C1464-16

Standard Specification for Bent Glass

ABSTRACT
This specification covers the standard for bent glass proposed for use in general building construction, furniture, display, and various other non-automotive applications. When the glass is specified as chemically strengthened, heat-strengthened, or fully tempered, the fabrication processes must be completed prior to the strengthening. The glass specimen shall also undergo impact testing for safety glazing.
SCOPE
1.1 This specification covers the requirements for bent glass used in general building construction, furniture, display, and various other non-automotive applications.  
1.2 The dimensional values, stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.  
1.3 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification.   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.
