Реферат This specification is intended for the destructive ball drop testing of laminated flat glass products used in architectural glazing. It provides a basis for evaluating the impact performance of laminated flat glass when a 2.3 kg, 83 mm diameter smooth solid steel ball is dropped from a specified height. The requirements are applicable to laminated architectural flat glass products that are symmetrical and asymmetrical annealed, heat-strengthened, chemically strengthened, and fully tempered.

1.1 This specification covers the destructive ball drop testing of laminated flat glass products intended for use in architectural glazing applications.

1.2 This specification 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 specified height.

1.3 This specification does not yield data that is a substitute for safety glazing test requirements of ANSI Z97.1 or CPSC 16 CFR 1201. Qualification under this specification provides a basis for judgment of the ability of specimens to withstand the appropriate shot-bag impact. This specification provides a mechanism to allow fabricators a less cumbersome and lower cost method for the evaluation of impact performance that may be performed on a frequent basis while reducing the amount of waste materials generated from traditional impact tests.

1.4 This specification 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 measurement 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 4 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.
