1.1 This specification covers the quality requirements of flat laminated glass consisting of two or more lites of glass bonded with an interlayer material for use in building and related applications.

1.2 Depending on the number, thickness, and treatment of lites, and the number and thickness of interlayers, the glass shall be laminated for applications including, but not limited to, safety, security, detention, hurricane/cyclic-wind resistance, blast resistance, bullet resistance, sound reduction, and decorative glazing.

1.3 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 X1.)

1.4 The dimensional values, except thickness designations, stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
