Go Gauges and Not Go Gauges of EN 50075 Figure 1

1 Scope

This standard applies to flat non-rewirable two-pole plugs without earthing contact with a rated voltage of 250 Va.c. and a rated current of 2,5 A. They are supplied with a cord, for the connection of equipment of class lI, for household and similar purposes, and having no special protection against ingress of water are intended for indoor use.

Plugs complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 *C, but occasionally reaching 35 C. Plug portions of adaptors or equipment, such as razors or lamps with rechargeable batteries, plug-in transformers, etc., shall comply with the requirements of this standard as far as they reasonably apply.

2 Definitions

Where in this standard the term “plug” is used, plugs according to this standard are meant, unless otherwise specified.
Where in this standard the terms voltage and current are used, they imply r.m.s. values, unless otherwise specified.
The following definitions apply for the purpose of this standard:
2.1 A plug is a device having pins designed to engage with the contacts of a socket-outlet and also incorporating means for the electrical connection and mechanical retention of a cord.
2.2 A non-rewirable plug is a plug so constructed that it forms a complete unit with the cord after connection and assembly by the manufacturer (see also 9.1).
The manufacturer referred to in this definition is either the manufacturer of:
– the plug or the cord set,
– the cord,
– the appliance or equipment.
2.3 A moulded-on plug is a non-rewirable plug the manufacture of which is compleled by insulating material moulded around the pre-assembled component parts and the terminations.

1. Application: This plug and socket test gauge is mainly used to test and inspect whether the structure and size of plugs and sockets conform to EN 50075 ( BS EN 50075:1991 ) standards. And the mainly application industries is electronics, electrical appliances, plugs and sockets and other similar areas.

2. Features: Gauge dimensions, tolerances, material, hardness, surface roughness conform to the standards requirements; Material hardness is more than 50HRC;Material thermal expansion coefficient is small,dimensions and tolerances is stable and reliable.
