LTPD Lot Tolerance Percent Defective

The linear inner defect tolerances corresponding to the safety graduations are stipulated in " in use pressure vessel inspection stipulation",item 36,table 3.

《在用压力容器检验规程》第36款表3规定了相应安全等级的线性埋藏缺陷容限，本文运用《CVDA—84压力容器缺陷评定规范》，对其它一切条件不变而只有应力水平发生变化时相应安全等级的缺陷容限的变化量和变化规律作初步探讨，希望对表3从强制性规定转为指导性条款起一定的参考和促进作用。
