商用和拉制的连续电解镀锡冷轧碳素钢板

[中文适用范围]： 本国际标准适用于通过电镀锡在卷材或切割长度形式上涂覆的商业和绘图质量的冷轧碳钢板。该产品通常称为电解镀锡板，用于需要可焊性、外观重要或在特定条件下具有一定耐腐蚀性且可以指定涂层质量的情况。涂层表示为两个表面上的总涂层，单位为克每平方米。指定的涂层质量应与所需的使用寿命、基材厚度和涉及的成型要求相兼容。命名系统（第4条）包括涂层名称、涂层条件和质量。 本国际标准不包括镀锡板和黑钢板。 [外文原描述]： ISO 5950:2012 applies to cold-reduced carbon steel sheet of commercial and drawing qualities coated in coil or cut length forms by electro-deposition of tin. The product is commonly known as electrolytic tin-coated sheet and is used where solderability is desired, appearance is important, or a degree of corrosion resistance under specific conditions is advantageous and coating mass can be specified. The coating is expressed as the total coating on both surfaces, in grams per square metre. The coating mass specified should be compatible with the desired service life, thickness of the base metal and the forming requirements involved. A designation system includes the coating designation, coating condition and quality. ISO 5950:2012 does not cover tinplate and blackplate.
