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環境應力開裂敏感性的試驗方法和技術要求

試驗范圍

本標準規定了灌溉用聚乙烯(PE)管材由插入式管件引起環境應力開裂敏感性的試驗方法和技術要求。本標準適用于用插入式管件配合的灌溉用聚乙烯(PE)壓力管材的環境應力開裂敏感性試驗方法。

試驗原理

經狀態調節的管段兩端180°彎折，以形成兩個u彎 ，并在（70±2）℃下將其浸于含活性溶液的玻璃燒杯中放置1h，然后將管段取出擦拭干凈后檢查彎折處的可見裂紋。
