ISO 1460-2020 pdf download.Metallic coatings – Hot dip galvanized coatings on ferrous materials一 Gravimetric determination of the mass per unit area. 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. 2 Normative references There are no normative references in this document. 3 Terms and definitions No terms and definitions are listed in this document.
