The ISO 11949-1995 standard specifies the classification, representation, dimensional tolerances, technical requirements, inspection, Encasement and delivery of cold-rolled Eletroplating tin sheets. The standard applies to low-carbon steel Eletroplating tin sheets with a thickness of 0.14 to 0.55mm, which are divided into two types: primary cold rolling and secondary cold rolling. It defines the different grades (Class I, Class II), steel grades (Class D, Class L, Class MR), surface Appearance (bright, stone pattern, etc.) of Eletroplating tin sheets, and corresponding technical requirements such as tin layer purity and passivating treatment. Measuring methods, test requirements and inspection rules are also specified to ensure product mass and conformity.
