标准摘要
[中文适用范围]： 本文件规定了铝及铝合金在5%（质量分数）氯化钠溶液中使用固定浓度乙酸作为氧化剂、采用两电极系统的点蚀电位测量方法。本文件提供了一种简便的测试方法，可对铝及铝合金进行评级，并且特别适用于评估薄层 clad 材料的牺牲阳极保护性能，因为该测试方法不会造成试样明显损坏 [外文原描述]： This document specifies a test method for the measurement of the pitting potential of aluminium and aluminium alloys in sodium chloride solution of a mass fraction of 5 %, with a fixed concentration of acetic acid as the oxidant, using a two-electrode system. This document provides a simple method for ranking aluminium alloys and is especially useful for evaluating galvanic protection performance of thin clad materials because the test method causes little specimen damage.
英文名称Two-electrode method using acetic acid to measure pitting potential of aluminium and aluminium alloys in chloride solutions
