IEC60320-1C2 Maximum Pullout Strength Of Gauge

For standard gauge inspection and check GB17465.1-2009, IEC60320-1 appliance coupler.
Electronic and electrical appliances, electrical accessories, plugs and sockets, etc..
Gauge dimensions, tolerances, materials, hardness, surface roughness should conform to the standard
Surface corrosion and abrasion resistance, can resist may occur in normal use in the process of corrosion of contact surfaces of the operator's hand sweat, the corrosion effect quite in NaCl salt solution or NH4Cl salt solution corrosion) and not from rust

The hardness of the material reaches more than 60.

The material's thermal expansion coefficient is small, the size and the tolerance are stable and reliable GB17465.1-2009, IEC60320-1
