Specifies requirements for the classification, mass, quality and testing of zinc coatings on open sections produced from electrogalvanized steel strip. Appendices give methods for the determination of coating mass and local thickness, and general advice on the corrosion protection, transport and storage and renovation of damaged areas, of electrogalvanized coatings.

This Interim Standard specifies requirements for the classification, mass, quality and testing of zinc coatings on open sections produced from electrogalvanized steel strip.Matters relating to the quality, properties, or dimensional requirements of the steel open sections are outside the scope of this Standard.NOTES:1 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.2 Alternative means for determining compliance with this Interim Standard are given in Appendix B.3 General information on factors that affect the corrosion of zinc coated steel is given in Appendix C.
