Unified system of corrosion and ageing protection. Metals, alloys, metallic and non-metallic coatings. Permissible and impermissible contacts with metals and non-metals
本标准适用于一般用非铁金属线网(以下简称线网
Non - fernous Metal Wire Nettings
Non-magnetic metallic coatings on metallic and non-metallic basis materials — Measurement of coating thickness — Phase-sensitive eddy-current method
Polyvynil chloride (PVC) coated gabion and gabion wire
Valves - Full bore non ferrous metal ball valves
Plain bearings. Metallic multilayer plain. Non-destructive ultrasonic testing of bond for bearing metal layer and backing
本标准规定了使用相敏涡流测厚仪损测量金属和非金属基体上非磁性金属覆盖层厚度的方法,如: a)钢铁基体上镀锌、镉、铜、锡或铬; b)复合材料基体上镀铜或银。 与GB/T 4957幅敏涡流法相比,相敏涡流法对较小表面和较大曲率表面的镀层厚度测量误差,同时,受基体的磁性影响更小,但相敏涡流法受
