UL1026:
29.7 Leakage at a gasket during the hydrostatic-pressure test is not unacceptable unless it occurs at a pressure 40 percent or less of the required test value.”(UL136中并未提及这句话)。
Leakage at a gasket during the hydrostatic-pressure test is not unacceptable unless it occurs at a pressure 40 percent or less of the required test value.”
此语应翻译成:
在静压力测试时, 从密封圈泄漏是不可以不接受的,除非是在测试压力40%以下出现泄漏.
也就是说测试压力在40%以下泄漏是不可以接受的, 在40%以上测试压力下泄漏是可以接受的.
not unacceptable是为了强调和与unless承接.作者: gudongman 时间: 2011-12-15 18:33
