EN 13148:2010 – Copper and copper alloys – Hot-dip tinned strip
1 Scope
This European Standard 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 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
strip
flat rolled product of rectangular cross-section with uniform thickness manufactured in coils and supplied in as sheared coils or traverse wound coils, usually with slit edges
NOTE The thickness does not exceed one tenth of the width.
3.2
hot-dip tinned strip
strip which is tinned with coatings on each face of equal thickness by drawing in an appropriate manner through a bath of any molten tin or tin-lead alloy or other tin alloy
3.3
differentially hot-dip tinned strip
hot-dip tinned strip with coatings on each face of different thicknesses
3.4
partially hot-dip tinned strip
hot-dip tinned strip with coatings on each face of equal thickness, but covering only part of the strip in the longitudinal direction
3.5
base material (of a tinned strip)
part of the strip which, after the tinning process, belongs neither to the metallic coating nor to an intermetallic phase and diffusion zone
4 Designations
4.1 Material of the strip to be tinned
4.1.1 General
The material is designated either by symbol or number (see Tables 1 and 2).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1.
NOTE Although material symbol designations used in this European Standard might be the same as those in other standards using the designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412.
4.2 Material for the coating
The coating is designated by the coating type (see Table 3) or for non-standardized coatings, by the supplier’s designation.
NOTE Due to solution and/or diffusion processes the composition of the coating can differ from that of the melt.
