1.1 This test method covers the destructive ball drop testing of laminated flat glass products intended for use in architectural glazing applications. 1.2 This test method is intended for use as an in-plant quality control test to evaluate the impact performance of laminated flat glass when a 2.3 kg, 83 mm diameter smooth solid steel ball is dropped from a user selected height. 1.3 This test method is not a substitute for safety glazing test requirements of ANSI Z97.1 or CPSC 16 CFR 1201. 1.4 This test method is applicable to symmetrical and asymmetrical annealed, heat-strengthened, chemically strengthened, fully tempered laminated architectural flat glass including but not limited to: float, patterned, sheet, sand-blasted, grooved, and fritted. 1.5 The values stated in SI units are to be regarded as standard. No other units of measure are included in this standard. 1.6 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. Some specific hazards statements are given in Section 7 on Hazards. 1.7 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.
