ASTM F3007-19

5.1 The impact performance of laminated glass varies with the glass ply thickness, type, and kind as well as the thickness and type of interlayer used in the overall configuration.

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.

1.1 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.
