ISO 4042-1999 《Fasteners -- Electroplated Coatings》 Related products

The ISO 4042-1999 standard specifies dimensional requirements and platings thickness for fastener platings of steel or copper alloys and provides recommendations to prevent hydrogen embrittlement. The standard applies to threaded fasteners, platings and Miscellaneous threaded parts such as gaskets and pins. The specification details the size requirements before and after Eletroplating, hydrogen embrittlement risk control measures and methods of lifting anti-corrosion performance. Technical requirements and test methods for platings thickness are also covered, including local thickness and measurement of batch average thickness. The standard aims to ensure the performance and mass of fasteners after Eletroplating treatment to meet the requirements of use.
