标准范围

本文件规定了在实验室中评估镀铬零件在除冰盐（尤其是氯化钙）存在下耐腐蚀性的仪器、试剂和程序。本方法主要适用于镀铬装饰件，尤其是电镀镍铬或铜镍铬的外部（汽车）件。本文件模拟了在冬季，在高盐浓度的吸湿性和腐蚀性除冰盐和导电泥浆存在于镀铬沉积物上时的特殊腐蚀。

This document specifies the apparatus, reagents, and procedure to assess the corrosion resistance of chromium electroplated parts in the presence of de-icing salts (especially calcium chloride) in the laboratory.This method is primarily applicable to decorative parts plated with chromium, especially to exterior (automobile) parts electroplated with nickel-chromium or copper-nickel-chromium.This document simulates a special corrosion in the presence of hygroscopic and corrosive de-icing salt and conductive mud with a high salt concentration on chromium electroplated deposits during winter.
