PA2是否与90//10有矛盾之处？

如题，大家讨论一下PA2关于膜厚测量的标准（特别是最大值最小值的界定）是否与90/10冲突？

比如PSPC规定的最低膜厚为多少，而根据PA2标准的允许最低膜厚为多少。

无矛盾！pa2.要3点的平均值而已，pspc参考的pa2，怎么会矛盾

4.3 CONFORMANCE TO SPECIFIED THICKNESS 规定厚度的符合
4.3.1 Minimum Thickness: The average of the spot measurements for each 10 m2 (100 ft2) area shall not be less than the speciﬁed minimum thickness. Although no single spot measurement in any 10 m2 (100 ft2) area shall be less than 80% of the speciﬁed minimum thickness, it is possible for any single gage reading to under-run by a greater amount. If the average of the spot measurements for a given 10 m2 (100 ft2) area meets or exceeds the speciﬁed minimum thickness, but one or more spot measurements is less than 80% of the speciﬁed minimum thickness, additional measurements will more precisely deﬁne the non-conforming area and facilitate repair (see Appendix 1 and Notes 7.16 and 7.17).
最小厚度：每10 m2 (100平方英尺)的区域内的单组测量值的平均值不应低于规定的最小厚度。即使在任何10 m2 (100平方英尺)区域内没有单组测量值低于规定最小膜厚的80%，但有可能单个测厚仪读数会给出更低的数值。如果在给定的10 m2 (100平方英尺)的区域内单组测量值的平均值符合或超过规定的最小厚度，但一个或多个单组测量值低于规定最小厚度的80%，则需要追加测量来确定不符区域并进行修补（详见附录1和注释7.16/7.17）。
4.3.2 Maximum Thickness: The average of the spot measurements for each 10 m2 (100 ft2) area shall not be more than the speciﬁed maximum thickness. Although no single spot measurement in any 10 m2 (100 ft2) area shall be more than 120% of the speciﬁed maximum thickness, it is possible for any single gage reading to over-run by a greater amount. If the average of the spot measurements for a given 10 m2 (100 ft2) area meets or falls below the speciﬁed maximum thickness, but one or more spot measurements is more than 120% of the speciﬁed maximum thickness, additional measurements will more precisely deﬁne the non-conforming area and facilitate repair (see Appendix 1 and Notes 7.16 and 7.17).
最大厚度：每10 m2 (100平方英尺)的区域内的单组测量值的平均值不应高于规定的最大厚度。即使在任何10 m2 (100平方英尺)区域内没有单组测量值高于规定最大膜厚的120%，但有可能单个测厚仪读数会给出更高的数值。如果在给定的10 m2 (100平方英尺)的区域内单组测量值的平均值符合或低于规定的最大厚度，但一个或多个单组测量值超过规定最大厚度的120%，则需要追加测量来确定不符区域并进行修补（详见附录1和注释7.16/7.17）。

理解楼主的问题了，关于最小厚度方面，是有点矛盾的。
最大厚度方面，与PSPC的90-10原则，倒并不一定矛盾。
