Lead-free tin coatings provide superior electrical conductivity and corrosion protection. The method of plating is often used to preserve the solderability of under-plated deposits such as copper or nickel. Hence it is important to determine the extent of lead in tin coatings to assess whether it is capable of providing adequate protection to the substrate.
BS 6534 is a British Standard that describes a method for the quantitative determination of lead in tin coatings on ferrous or copper base articles, typically culinary utensils.
Note: The titles of the publications referred to in this standard are listed on the inside back cover.
BS 6534 on the quantitative determination of lead in tin coatings is useful for:
Tin coating is the process of co-depositing a layer of tin and a layer of lead onto a substrate or base component. The alloy compositions used in tin-lead plating are determined by the finished product's desired qualities and intended application.
BS 6534 provides you with best industry method and guidance to accurately determine the presence and extent of lead in tin coatings. As a result, you can evaluate whether or not your coating materials are fit for purpose and can play a positive role in the quality and performance of the end-product application.
Thus, BS 6534 methods can help demonstrate the ability of tin coatings to enhance the durability and service-life of tin-coated ferrous or copper base components.
