塑料管材与管件不透光性测试方法的研究

Determination of Opacity for Plastics Pipes and Fittings

参照国际标准并结合其不同版本内容的变化 ,通过验证和对比试验 ,对塑料管材与管件不透光性测试的试验参数和操作中的主要影响因素进行了分析 。

Parameters and important factors for determination opacity of plastic pipes and fittings were discussed based on validating and paralleling experiments,according to the international standard ISO/DIS7686 and the change of different revisions.Finally,some suggestions to the problems are illustrated.
