The differences in minimum average coating thickness for most steel articles are small. The easiest way to sum up the differences between the two specifications is by comparing the coating thickness requirements in a table. In comparing the two standards, and and, there are no major differences. The appendices include information such as required information to be supplied by the purchaser to the galvanizer, safety and process requirements, coating properties, determination of coating thickness, and a bibliography of other referenced specifications. The ISO specification is 15 pages in length and includes 5 appendices. This specification is essentially equivalent to the American Society of Testing and Materials. International Standards Organization ISO 1461, Hot Dip Galvanized Coatings on Fabricated Iron and Steel Articles – Specifications and Test Methods, is a general galvanizing specification.
