                          1.試驗介質:
                          a)閿體強度試驗和高壓密封試驗,用水、煤油或黏度不高于水的非腐蝕性液體。
                          b)低壓密封試驗,用空氣或惰性氣體。

                          2.試驗壓力:
                          a)閥體強度試驗壓力為公稱壓力的1.5倍
                          b)高壓密封試驗壓力為公稱壓力的1.1倍。
                          c)低壓密封試驗壓力為0.6MPa
                          d)止回閥的密封試驗壓力為公稱壓力。

                          3.試驗的持續時間與允許最大泄漏量:
                          a)閥體強度試驗保壓時間應符合表9的要求,閥體(包括填料函和中法蘭處)不得有滲漏或結
                          構損傷。
                          b)密封試驗保壓時間應符合表10的要求,密封副的允許最大滲漏率應符合表11的要求。
