ISO527-1/2新旧版本标准的对比研究

Study on the Old and the New Edition of the ISO 527-1/2

2012年,ISO标准化组织发布了最新的ISO 527-1/2:2012文件,替代原有的1993版本。经解读,IS0 527-1:2012总则在结构上有轻微的改变,而在内容上主要是对术语定义、测试速度等进行了修订,ISO 527-2:2012试验条件中新增了1A型样条的标距75 mm。术语的修订、测试速度的多样性选择、试验条件的改变等都将会对塑料材料的性能测试结果产生影响。

In 2012, the International Organization for Standardization released the second edition of ISO 527-1/2, and replaced the first edition（ISO 527-1/2：1993）. The interpretation of 1SO 527-1：2012, there was a slight change in the structure, and the definitions, test speed were revised .In the ISO 52%2：2012, the type IA test specimens preferred 75mm of gauge length. The test conditions changed, will impact the performance test results of the plastic material.
