What is BS EN 13603 about?
BS EN 13603 specifies methods for assessing the tin coating on drawn round copper wire for the manufacture of electrical conductors, e.g. according to EN 13602.
BS EN 13603 includes test methods for the determination of the following characteristics:
- The thickness of the unalloyed tin coating
- Continuity of the tin coating
- Adherence to the tin coating
Who is BS EN 13603 for?
BS EN 13603 on protection of copper wires for electrical purposes is relevant to:
- Manufacturer and suppliers of tin coating for copper wire
- Electrical engineers
- Solderers
- Shouldering and equipment manufacturers
- Automotive engineers
Why should you use BS EN 13603?
Tinning of copper wires protects the copper wire from corrosion and premature cable failure while having no impact on its highly conductive nature.
BS EN 13603 refers to two different methods to measure the thickness of the tin coating layers on copper wires. The first one is based on the electrolytic dissolution of the tin layer. The second one is based on the direct measure of the tin layer on the wires by means of the reflection of an X-ray beam on its surface.
BS EN 13603 provides information on the necessary reagents and materials, procedure for determining the thickness of unalloyed tin coatings and measurement techniques.
As a buyer of BS EN 13603, compliance with the test methods and procedures will enable you to undertake the manufacture of high-quality tin coated copper wires that enhance the service-life of the copper wire, especially when used in environments that have high humidity or moisture that can lead to oxidation of copper.
Standardising processes with BS EN 13603 ensures will enhance credibility and allow for seamless expansion in marine applications.
What’s changed since the last update?
BS EN 13603:2021 supersedes BS EN 13603:2013, which is withdrawn.
In comparison with the previous edition, the following technical modification has been made:
- Included the X-ray fluorescence analysis (XRF) to measure the thickness of the tin layer
