1.1这些试验方法包括以下两种试验: 1.1.1方法A，硫酸铁-硫酸试验（第3节至第10节，包括第3节至第10节）-该试验方法描述了进行沸腾硫酸铁-50%硫酸试验的程序，该试验测量了某些富镍含铬合金对晶间腐蚀的敏感性（见术语G15），这可能在某些使用环境中遇到。通过本试验方法获得的均匀腐蚀速率是合金成分微小变化的函数，很容易掩盖合金N10276、N06022、N06059和N06455整体腐蚀速率的晶间腐蚀成分。 1.1.2方法B，混合酸氧化盐试验（包括第11节至第18节）-该试验方法描述了进行沸腾23%硫酸+1.2%盐酸+1%三氯化铁+1%氯化铜试验的程序，该试验测量了某些镍的敏感性- 当晶界析出程度较高时，富铬轴承合金的腐蚀速率呈阶梯函数增加。 1.2这两种试验方法的目的是检测受加工或成分变化或两者影响的晶间腐蚀敏感性。在其他环境中，易受影响的材料可能会或可能不会受到晶间腐蚀。这必须通过具体测试或服务经验独立确定。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。危险咨询声明见5.1.1、5.1.3、5.1.9、13.1.1和13.1.11。

1.1 These test methods cover two tests as follows: 1.1.1 Method A, Ferric Sulfate-Sulfuric Acid Test (Sections 3 through 10, inclusive)-This test method describes the procedure for conducting the boiling ferric sulfate-50% sulfuric acid test which measures the susceptibility of certain nickel-rich, chromium-bearing alloys to intergranular corrosion (see Terminology G15), which may be encountered in certain service environments. The uniform corrosion rate obtained by this test method, which is a function of minor variations in alloy composition, may easily mask the intergranular corrosion components of the overall corrosion rate on alloys N10276, N06022, N06059, and N06455. 1.1.2 Method B, Mixed Acid-Oxidizing Salt Test (Sections 11 through 18, inclusive)-This test method describes the procedure for conducting a boiling 23% sulfuric + 1.2% hydrochloric + 1% ferric chloride + 1% cupric chloride test which measures the susceptibility of certain nickel-rich, chromium-bearing alloys to display a step function increase in corrosion rate when there are high levels of grain boundary precipitation. 1.2 The purpose of these two test methods is to detect susceptibility to intergranular corrosion as influenced by variations in processing or composition, or both. Materials shown to be susceptible may or may not be intergranularly corroded in other environments. This must be established independently by specific tests or by service experience. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Hazard advisory statements are given in 5.1.1, 5.1.3, 5.1.9, 13.1.1, and 13.1.11.
