标准范围
The purpose of this International Standard is to evaluate, by means of soft body impactors, safebreakage characteristics of glazing products intended to reduce cutting and piercing injuries to personsthrough accidental impact.This International Standard examines test methods currently employed to determine the pendulumimpact performance of safety glass. Use of the methodologies in this International Standard improvesthe reproducibility of test results and gives a common basis of classification. The aim is for theperformance of glass products manufactured and tested in various countries to be better understoodand more consistent.Two types of soft body impactors are defined. The traditional shot bag impactor is detailed both interms of manufacture and maintenance in an attempt to overcome problems associated with suchimpactors becoming misshapen. The twin tyre impactor is also detailed.The test equipment, excluding the impactor, is also described. A method of calibrating the test frame isgiven. The benefit of calibrating the test equipment is the increased reproducibility of the test results.Classification of glass products is also detailed. The classification system allows information on thefollowing to be given:a) the maximum drop height at which the glass either did not break or broke safely, i.e. in a mannersimilar to laminated glass or toughened glass;b) the manner in which the glass would break, i.e. as toughened glass, laminated glass, annealed glass,irrespective of whether or not the glass was broken during the test;c) the maximum drop height at which the glass either did not break or broke safely, i.e. in a mannersimilar to laminated glass.This International Standard does not specify the intended use of the products, but provides a methodof classification in terms of the performance of the materials being tested. The impact energy used forthe various levels of classification are designed to provide the intended user or the legislator with theinformation to assist in defining the level of safety and protection required relative to the intendedlocation at which the selected safety glass is to be used.
