ISO 29584:2015的目的是通过软体冲击器评估嵌装玻璃产品的安全破损特性,以减少因意外冲击而对人员造成的切割和穿孔伤害。
ISO 29584:2015检查了目前用于确定安全玻璃摆锤冲击性能的试验方法。使用本国际标准中的方法提高了试验结果的再现性,并提供了共同的分类依据。其目的是为了更好地了解各国制造和测试的玻璃产品的性能,使其更加一致。
定义了两种类型的软体碰撞器。传统的弹丸袋冲击器在制造和维护方面都进行了详细说明,试图克服与此类冲击器变形相关的问题。还详细介绍了双轮胎碰撞器。
还描述了试验设备,不包括冲击器。给出了测试架的标定方法。校准测试设备的好处是增加了测试结果的再现性。
玻璃制品的分类也很详细。
分类系统允许提供以下信息:
a) 玻璃未破裂或安全破裂的最大跌落高度,即以类似夹层玻璃或钢化玻璃的方式;
b) 玻璃破裂的方式,即钢化玻璃、夹层玻璃、退火玻璃,无论玻璃在试验期间是否破裂;
c) 玻璃未破裂或安全破裂的最大跌落高度,即以类似夹层玻璃的方式。
ISO 29584:2015未规定产品的预期用途,但提供了根据被测材料性能进行分类的方法。用于不同等级分类的冲击能量旨在为预期用户或立法者提供信息,以帮助确定所选安全玻璃使用的预期位置所需的安全和保护等级。
The purpose of ISO 29584:2015 is to evaluate, by means of soft body impactors, safe breakage characteristics of glazing products intended to reduce cutting and piercing injuries to persons through accidental impact.
ISO 29584:2015 examines test methods currently employed to determine the pendulum impact performance of safety glass. Use of the methodologies in this International Standard improves the reproducibility of test results and gives a common basis of classification. The aim is for the performance of glass products manufactured and tested in various countries to be better understood and more consistent.
Two types of soft body impactors are defined. The traditional shot bag impactor is detailed both in terms of manufacture and maintenance in an attempt to overcome problems associated with such impactors 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 is given. 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 the following to be given:
a) the maximum drop height at which the glass either did not break or broke safely, i.e. in a manner similar 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 manner similar to laminated glass.
ISO 29584:2015 does not specify the intended use of the products, but provides a method of classification in terms of the performance of the materials being tested. The impact energy used for the various levels of classification are designed to provide the intended user or the legislator with the information to assist in defining the level of safety and protection required relative to the intended location at which the selected safety glass is to be used.
