ISO 14708-3:2017提供了适用于需要进行防腐处理的物品的一般设计原则的指南和建议。 渗锌涂层对物品的保护取决于涂层的应用方法、物品的设计和物品暴露的特定环境。可通过使用附加涂层（不在本文件范围内）进一步保护镀锌制品，例如有机涂层（湿漆或粉末涂层）。 当应用于镀锌制品时，这种涂层组合通常被称为“双重系统”。 ISO 12944-5和EN 13438中提供了关于该主题的一般指导。 本文件不包括在役钢的镀锌层防腐维护。 具体的产品相关要求（例如紧固件或管道上的镀锌涂层等）优先于这些一般建议。

ISO 14708-3:2017 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 this document), 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 this document. Specific product-related requirements (e.g. for sherardized coatings on fasteners or tubes, etc.) will take precedence over these general recommendations.
