What is BS 1872 - electroplated tin coating requirements about?
BS 1872 is a British Standard that specifies requirements for electroplated coatings of tin. The coatings may be dull or bright as electroplated or may be flow-melted by fusion after electroplating.
These coatings are intended for use on ferrous and non-ferrous basis metals and also on printed wiring boards.
A classification scheme is included by which the nature of the basis metal and undercoat, if any, and the tin coating thickness can be defined.
Note 1: BS 1872 does not specify any requirements for the condition, finish, or surface roughness of the basis material before electroplating.
Note 2: Attention is drawn to BS 9760, which specifies the capability approval procedure and rules for printed circuits of assessed quality.
Note 3: BS 1872 is not applicable to electroplating of:
- Threaded components (see BS 3382-5)
- Tin coated copper wire (see BS 4393)
- Sheet, strip (see BS 2920) or wire in the unfabricated form, or of coil springs
- Steels with tensile strengths greater than 1000 MPa because such steels require hydrogen embrittlement relief after plating.
Note 4: BS 1872 does not apply to coatings applied by other processes, e.g. auto catalytic, immersion or “electroless” processes.
Who is BS 1872 - electroplated tin coating requirements for?
BS 1872 on electroplated tin coating requirements is useful for:
- The metals industry
- Manufacturers of metal products such as utensils
- Manufacturers of metal hardware such as handles and taps
- Manufacturers of metal components used in construction
- Manufacturers of electronics components
- The aerospace Industry

Why should you use BS 1872 - electroplated tin coating requirements?
Electroplated tin coating, that involves using an electric current to create a coating of tin on substrates; is an effective method of protecting base metals from rust and corrosion.
BS 1872 provides you with guidelines for coating classification, heat treatment of steel requirements, sampling, and testing procedures for electroplated coatings of tin. BS 1872 also provides you with guidelines for information to be supplied by the purchaser to the electroplater.
BS 1872 facilitates clear communication between the purchaser and the vendor in terms of requirements. BS 1872 guidelines help you to achieve high-quality electroplated tin coatings on base metals, extending the service life of products.
