标准摘要
[中文适用范围]: 本文件提供了确定阳极氧化或自催化、机械、化学转化、电沉积、热浸镀锌以及使用重量分析和其他化学分析的化学或物理气相沉积沉积涂层测量区域的平均表面密度的指南已达到一定程度的国家或国际标准化的程序。 描述了多种程序,包括: ——用于化学或电化学溶解涂层或基材以确定涂层表面密度的重量分析程序; ——称重未涂覆基材和涂覆(成品)样品以确定涂层表面密度的重量分析程序; ——利用涂层溶解通过仪器化学分析方法测定涂层表面密度的分析程序。 除 ISO 3892 中描述的重量分析法外,本文件没有给出所引用方法的测量不确定度。 [外文原描述]: This document gives guidelines for determining the average surface density over a measured area of anodic oxide or of a coating deposited autocatalytically, mechanically, by chemical conversion, by electrodeposition, by hot dip galvanizing and by chemical or physical vapour deposition using gravimetric and other chemical analysis procedures that have attained some degree of national or international standardization. A variety of procedures are described and include: — gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate to determine the coating surface density; — gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to determine the coating surface density; — analytical procedures that utilize dissolution of the coating for determination of the coating surface density by instrumental chemical analysis methods. With the exception of the gravimetric method as described in ISO 3892, this document does not give the measurement uncertainties of the methods cited.
