1. Scope
1. Scope 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 2270 g, 83 mm diameter (5 lb., 3.25 in. 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, heatstrengthened, chemically strengthened, and fully tempered laminated architectural flat glass including but not limited to: float, patterned, sheet, sand-blasted, grooved and fritted.
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. Will be adopted by government agency
