标准名称

GB/T 15819 Polyethylene(PE)pipes for irrigation laterals-Test method and specification of susceptibility to environmental stress cracking induced by insert-type fittings

GB/T 15819 灌溉用聚乙烯（PE)管材由插入式管件引起环境应力开裂敏感性的试验方法和技术要求

试验范围

本标准规定了灌溉用聚乙烯(PE)管材由插入式管件引起环境应力开裂敏感性的试验方法和技术要求。本标准适用于用插入式管件配合的灌溉用聚乙烯(PE)压力管材的环境应力开裂敏感性试验方法。

试验原理

经状态调节的管段两端180°弯折，以形成两个u弯 ，并在（70±2）℃下将其浸于含活性溶液的玻璃烧杯中放置1h，然后将管段取出擦拭干净后检查弯折处的可见裂纹。
