ASTM C1443-99(2010)

Standard Specification for Glasses, Portlight, Circular, Fully Tempered

ABSTRACT
This specification covers circular, fully tempered, high clarity, flat glasses prescribed for use in portlight applications. The glazing quality float glasses are classified into four types according to the type of edge and the texture of each face. All products should conform to the required values for breaking strength, surface and edge compression, clarity, and warpage and quality of finish.
SCOPE
1.1 This specification covers the requirements for circular, fully tempered, high clarity, flat glasses used for portlight applications.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following safety hazard caveat pertains only to the test method portion, Section 11, 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.
