【英文标准名称】: Plastics - Determination of resistance to environmental stress cracking (ESC) - Part 3: Bent strip method 【原文标准名称】: 塑料制品.耐环境应力开裂(ESC)测定.第3部分:弯曲带法 【标准号】: ISO 22088-3-2006 【标准状态】: 现行 【国别】: 国际 【发布日期】: 2006-08 【实施或试行日期】: 【发布单位】: 国际标准化组织(IX-ISO)【起草单位】: ISO/TC 61【标准类型】: ()【标准水平】: ()【中文主题词】: 弯曲试验;抗弯刚度;定义;测定;耐环境应力开裂(CSE);环境试验;材料试验;塑料;耐力;撕裂试验;应力;应力断裂;试验方法;试样;试验;电压【英文主题词】: Bend testing;Bending stiffness;Definitions;Determination;Environmental stress cracking;Environmental testing;Materials testing lastics;Resistance;Splitting tests;Stress;Stress crackings;Test methods;Test specimens;Testing;Voltage【摘要】: This part of ISO 22088 specifies a method for the determination of the environmental stress cracking (ESC) resistance of thermoplastics when they are subjected to a fixed flexural strain in the presence of chemical agents.ESC is indicated by the change of a suitably chosen indicative property of specimens that have been strained for a defined time in the environment. The method of test is suitable for determining the resistance of sheets and of flat test specimens, especially the sensitivity of localized surface regions of specimens, to ESC.The bent strip method is suitable for the determination of ESC caused by gases and liquids as well as solids containing migrating substances (e.g. polymeric adhesives and materials containing plasticizers) in contact with a specific polymer.Preferably, this method is used to determine the ESC resistance of rigid plastics that exhibit only moderate stress relaxation during the time of the test.This is essentially a ranking test and is not intended to provide data to be used for design or performance prediction.NOTE For a constant-strain test, refer to ISO 22088-5. For a constant-load test, refer to ISO 22088-2.【中国标准分类号】: G31【国际标准分类号】: 83_080_01【页数】: 10P;A4【正文语种】: 英语
