Significance and Use
5.2 Specific safety properties are required for laminated glass to meet the safety glazing requirements of ANSI Z97.1 and CPSC 16 CFR 1201. Compliance with the minimum quality requirements of Specification C1172 does not constitute compliance or assure compliance with the referenced safety glazing standards.
5.3 While this test method does not replace the test requirements of ANSI Z97.1 or CPSC 16 CFR 1201 safety glazing standards addressed above, destructive ball drop impact testing does provide a method of expeditious in-plant evaluation of laminated glass products being fabricated.
5.4 Impact procedures for testing in accordance with safety glazing standards ANSI Z97.1 and CPSC 16 CFR 1201 differ from this ball drop test method; however, the penetration resistance of a single laminated lite can be determined and used for quality control purposes.
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.
1.4 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.
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 7 on Hazards.
