標(biāo)準(zhǔn)編號：ASTM G16−95（2010）
標(biāo)準(zhǔn)概述：This guide covers and presents brie?y some generally accepted methods of statistical analyses which are useful in the interpretation of corrosion test results.This guide does not cover detailed calculations and methods, but rather covers a range of approaches which have found application in corrosion testing.

標(biāo)準(zhǔn)名稱：Standard Test Method for Electrochemical Critical Pitting Temperature Testing of Stainless Steels
標(biāo)準(zhǔn)編號：ASTM G150–99
標(biāo)準(zhǔn)概述：This test method covers a procedure for the evaluation of the resistance of stainless steel and related alloys to pitting corrosion based on the concept of the determination of a potential independent critical pitting temperature （CPT）。This test methods applies to wrought and cast products including but not restricted to plate, sheet, tubing, bar, forgings, and welds.The standard parameters recommended in this test method are suitable for characterizing the CPT of austenitic stainless steels and other related alloys with a corrosion resistance ranging from that corresponding to solution annealed UNS S31600 （Type 316 stainless steel） to solution annealed UNS S31254 （6 % Mo stainless steel）。

標(biāo)準(zhǔn)名稱：Standard Test Method for Electrochemical Critical Pitting Temperature Testing of Stainless Steels
標(biāo)準(zhǔn)編號：ASTM G61-86（2009）
標(biāo)準(zhǔn)概述：This test method covers a procedure for conducting cyclic potentiodynamic polarization measurements to determine relative susceptibility to localized corrosion （pitting and crevice corrosion） for iron-, nickel-, or cobalt-based alloys in a chloride environment. This test method also describes an experimental procedure which can be used to check one's experimental technique and instrumentation.
