NS-EN ISO 14713-3:2009 锌涂层 结构中钢铁防腐蚀指南和建议 第3部分：渗锌 (ISO 14713-3:2009)
Zinc coatings - Guidelines and recommendations for the protection against corrosion of iron and steel in structures - Part 3: Sherardizing (ISO 14713-3:2009)
Full Description ADOPTED_FROM:EN ISO 14713-3:2009 ISO 14713-3:2009 provides guidelines and recommendations regarding the general principles of design that are appropriate for articles to be sherardized for corrosion protection. The protection afforded by the sherardized coating to the article will depend upon the method of application of the coating, the design of the article and the specific environment to which the article is exposed. The sherardized article can be further protected by application of additional coatings (outside the scope of ISO 14713-3:2009), such as organic coatings (wet paints or powder coatings). When applied to sherardized articles, this combination of coatings is often known as a “duplex system”. General guidance on this subject can be found in ISO 12944-5 and EN 13438. The maintenance of corrosion protection in service for steel with sherardized coatings is outside the scope of ISO 14713-3:2009. Specific product-related requirements (e.g. for sherardized coatings on fasteners or tubes, etc.) will take precedence over these general recommendations.
