ISO/DIS 11949.2:2014 pdf free.Cold-reduced tinmill products—Electrolytic tinplate.
ISO/DIS 11949.2 specifies requirements for single and double cold-reduced low-carbon mild steel electrolytic tinplate in the form of sheets or coils.
Single cold-reduced tinplate is generally specified in nominal thicknesses that are multiples of
0,005 mm, from 0,150 mm up to and including 0,600mm. Double cold-reduced tinpiate is generally
specified in nominal thicknesses that are multiples of 0,005 mm, from 0,100 mm up to and including
0,360mm.
This International Standard applies to coils and sheets cut from coils in nominal minimum rolling widths of 600 mm.1
In addition, the general technical delivery requirements of ISO 404 are applicable.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
3.1 blackplate cold-reduced low-carbon mild steel, applied for manufacturing electrolytic tinplate
3.2 electrolytic tinplate cold-reduced low-carbon steel sheet or coil coated on both surfaces with tin that is applied in a continuous electrolytic operation
3.3 differentially coated electrolytic tinplate cold-reduced electrolytic tinplate, one surface of which carries a heavier tin coating than the other
3.4 single cold-reduced description of product in which the blackplate has been reduced to the desired thickness in a cold- reduction mill and subsequently annealed and temper rolled
3.5 double cold-reduced description of product in which the blackplate has had a second major reduction after annealing
3.6 standard grade tinplate sheet product in sheet form which is confirmed to be suitable, under normal conditions of storage, for established lacquering and printing over the entire sheet and is:
a) free from surface imperfections which render the material unsuitable for the intended use;
b) free from damage which render the material unsuitable for the intended use Note 1 to entry: The standard material is compliant with the requirements as specified in this International Standard
3.7 batch annealed; box annealed BA annealed by the process in which the cold-reduced strip is annealed in coil form, within a protective atmosphere, for a predetermined time-temperature cycle
3.8 continuously annealed annealed by the process in which cold-reduced coils are unwound and annealed in strip form within a protective atmosphere.ISO/DIS 11949.2 pdf download.
