The linear inner defect tolerances corresponding to the safety graduations are stipulated in " in use pressure vessel inspection stipulation",item 36,table 3.
《在用壓力容器檢驗規(guī)程》第36款表3規(guī)定了相應(yīng)安全等級的線性埋藏缺陷容限，本文運用《CVDA—84壓力容器缺陷評定規(guī)范》，對其它一切條件不變而只有應(yīng)力水平發(fā)生變化時相應(yīng)安全等級的缺陷容限的變化量和變化規(guī)律作初步探討，希望對表3從強制性規(guī)定轉(zhuǎn)為指導(dǎo)性條款起一定的參考和促進作用。
