BS EN ISO 2179:2016规定了金属间化合物SnNi的电镀层要求，其成分约为65%（m/m）锡和35%（m/m）镍。它不适用于:螺纹部件；未经加工的板材、带材或线材上的涂层，或由其制成的物品上的涂层；螺旋弹簧涂层；电镀抗拉强度大于1000 MPa（或相应硬度）的钢，因为此类钢易发生氢脆。交叉引用:ISO 1462ISO 1463ISO 2064ISO 2177ISO 2819ISO 2859ISO 3497ISO 3543ISO 4519ISO 6988购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 2179:2016 specifies requirements for electroplated coatings of the intermetallic compound SnNi, with a composition of approximately 65% (m/m) tin and 35% (m/m) nickel.It does not apply to:threaded components;coatings on sheet, strip or wire in the unfabricated form, or on articles made from them;coatings on coil springs;electroplating of steels with tensile strength greater than 1,000 MPa (or of corresponding hardness), because such steels are subject to hydrogen embrittlement.Cross References:ISO 1462ISO 1463ISO 2064ISO 2177ISO 2819ISO 2859ISO 3497ISO 3543ISO 4519ISO 6988All current amendments available at time of purchase are included with the purchase of this document.
