标准摘要
[中文适用范围]： 本文件规定了测定黑色金属材料上热浸镀锌层单位面积质量的方法。 由于准确了解表面面积至关重要，因此本文档主要适用于面积易于确定的形状。 如果对于重样品，不能满足第 7 条的规定，则用另一种方法测定热浸镀锌层质量。 [外文原描述]： This document specifies a method of determining the mass per unit area of hot dip galvanized coatings on ferrous materials. Since an exact knowledge of the area of the surface is essential, this document is mainly applicable to shapes whose areas are easy to determine. If, with heavy samples, the specifications of Clause 7 cannot be met, then the hot dip galvanized coating mass is determined by another method.
英文名称Metallic coatings — Hot dip galvanized coatings on ferrous materials — Gravimetric determination of the mass per unit area
