What is BS EN 13148 - Hot-dip tinned strip about?
BS EN 13148 is a European standard on hot-dip tinned strips that discusses the best procedures and specifications required for manufacturing high-quality hot-dip tinned strips. BS EN 13148 specifies:
- The composition and tolerances on dimensions of strip produced by rolling in the thickness range from 0,10 mm up to and including 1,50 mm of copper and copper alloys to be tinned, with tin, a tin-lead alloy, or other tin alloys
- The composition of material normally used for the melt
- The properties of the strip before tinning
- The properties of hot-dip tinned strip
- The preferred thicknesses (mean values) and thickness ranges of coatings
- The edgewise curvature of hot-dip tinned strip
- The sampling procedure
- The methods of test to be used for verification of conformity to the requirements of this European standard
- The delivery conditions
Who is BS EN 13148 - Hot-dip tinned strip for?
BS EN 13148 on hot-dip tinned strip is relevant to:
- Manufacturer of hot-dip tinned strip
Why should you use BS EN 13148 - Hot-dip tinned strip?
Hot-dip tinned strip is manufactured by passing the strip through a molten bath of tin, tin-lead alloy, or other tin alloys. By this process, a solid bond is created between the metallic coating and the strip by the formation of a layer of an intermetallic phase and a diffusion zone.
The base metal is hot-dip tinned to protect it against corrosion, to facilitate soldering operations, to improve insertion and withdrawal forces of connectors, to reduce contact resistance at electrical junctions, and to avoid whisker growth on components. The properties of coatings can be modified by mechanical and/or thermal treatments.
As a user of BS EN 13148, you can be ensured of the properties and requirements of hot-dip tinned strip. With obedience and compliance to BS EN 13148, you can efficiently manufacture corrosion-resistant hot-dip tinned strips. With BS EN 13148 you can be ensured that the products consistently meet and exceed quality assurance targets.
BS EN 13148 exemplifies the required material composition and mechanical property that help you achieve precision in terms of product functionality and specification. BS EN 13148 provides you with comprehensive information useful throughout the process of production.
What’s changed since the last update?
BS EN 13148:2010 supersedes BS EN 13148:2001 which is withdrawn. In comparison with EN 13148:2001, the following significant technical changes were made:
- Table 3:
- Composition of Sn, increasing of the upper limits: Cu from 0,030 % to 2,0 %, Pb from 0,03 % to 0,1 % and Zn from 0,0010 % to 0,7 %
- Column “Material designation” and reference to “EN 610 and EN 29453” are deleted
- Table 4: column 0,2 % proof strength, at the 1st line (R220), the value “(min. 140)” where corrected in “(max. 140)”.
