标准范围

本文件描述了大气和低压（小于或等于50？kPa）金属储罐底板的声发射（AE）测试方法以及用于测试结果的分类系统。本文件适用于大气金属储罐底板腐蚀严重程度的声发射试验（AT）。该技术仅限于由建筑钢制成的储罐地板，并且依赖于主动腐蚀过程。它仅适用于地板腐蚀是主要损坏机制的情况。如果腐蚀条件没有改变，将获得良好的结果。

This document describes the testing methodology based on acoustic emission (AE) for atmospheric and low-pressure (less than or equal to 50 kPa on top of the tank) metallic storage tank floors and the classification system to be used for test results.

This document applies to acoustic emission testing (AT) for corrosion severity of atmospheric metal storage tank floors.

The technique is limited to tank floors made of construction steel and relies on an active corrosion process. It applies only in cases where corrosion of the floor is the governing damage mechanism. Good results will be obtained providing corrosion conditions have not changed.
