标准摘要
[中文适用范围]： 本部分ISO 6383规定了确定塑料薄膜或厚度小于1毫米的片材撕裂阻力的方法，试样为标准裤形试样，在规定的预处理条件、温度、湿度和试验速度下进行测试。该方法适用于柔性材料和刚性材料制成的膜和片材，前提是材料不会在测试期间发生脆性断裂，或不会以不可逆的方式变形，且试样腿部分变形所消耗的能量相对于撕裂所需能量来说不是微不足道的（即不忽略）。该方法可能不适合用于多孔板和薄膜的撕裂性能测定。 [外文原描述]： ISO 6383-1:2015 specifies a method of determining the tear resistance of plastic film or sheet less than 1 mm thick, in the form of standard trouser-shaped test specimens, tested under defined conditions of pre-treatment, temperature, humidity, and speed of testing. The method is applicable to film and sheeting of both flexible and rigid materials, provided that the material is not so rigid that brittle fracture occurs during the test, or so deformable, in an irreversible way, that the energy used in the deformation of the specimen legs is significant (i.e. is not negligible) with respect to the energy used in tearing. The method may not be suitable for determining the tear properties of cellular sheet and film.
