Foreword

This standard test method was developed to address a number of testing parameters

involved in the laboratory corrosion testing of clean metal test specimens in static chemical

cleaning solutions at temperatures above boiling (100°C [212°F]). Specifically, this standard

addresses those parameters not covered in ASTM(1) D 3263,1 including surface-to-volume ratio,

inhibitor handling, localized corrosion and pitting, and the reporting procedure, and is for use

specifically by those involved in the industrial cleaning industry. The intent is that these factors

will make the reported corrosion rates more useful for comparing chemical cleaning solutions and

inhibitors.

Because chemical cleaning solutions are used over a wide range of applications, no universal

test method to cover all cases is possible. This standard is intended to be used to obtain data

relevant to the cleaning of industrial equipment, such as boilers, heat exchangers, piping systems,

and tanks. Note that these tests use clean test specimens in a clean solution and the severity of

corrosion obtained in these tests will not be the same as if actual deposits were present.

This standard was prepared by NACE Task Group T-3M-5, a component of Unit Committee

T-3M on Chemical and Mechanical Cleaning, and is published by NACE International under the

auspices of Group Committee T-3 on Corrosion Science and Technology.

摘要：

NACE TM0398-1998 是由国际腐蚀工程师协会（NACE International）制定的一项标准试验方法，专门用于评估在高温高压条件下钢材的硫化物应力腐蚀开裂（SSC）敏感性。该标准为石油、天然气及化工行业中涉及酸性环境（如含硫化氢介质）的设备和管道选材、质量验收及失效分析提供了关键测试流程与判定依据，包括试样制备、加载方式、环境条件及结果评价等具体要求。掌握 NACE TM0398-1998 对于确保工程材料在苛刻腐蚀环境下的长期安全运行、降低风险及符合行业规范具有重要意义。
