IEC 60884 Figure 10 Socket Protective Test Needle with 1N

PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD AND SIMILAR PURPOSES

Part 1:Scope
This part of IEC 60884 applies to plugs and fixed or portable socket-outlets for a.c. only, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors.

The current is limited to 16 A maximum for fixed socket-outlets provided with screwless terminals.

This standard does not cover requirements for flush mounting boxes: however, it covers only those requirements for surface-type mounting boxes which are necessary for the tests on the socket-outlet.
NOTE 1 General requirements for mounting boxes are given in IEC 60670.

This standard also applies to plugs incorporated in cord sets, to plugs and portable socket-outlets incorporated in cord extension sets and to plugs and socket-outlets which are a component of an appliance, unless otherwise stated in the standard for the relevant appliance

This standard does not apply to:

– plugs, socket-outlets and couplers for industrial purposes;
– appliance couplers;
– plugs, fixed and portable socket-outlets for ELV;
NOTE 2 ELV values are specified in IEC 60364-4-41.
– fixed socket-outlets combined with fuses, automatic switches, etc.
NOTE 3 Socket-outlets with pilot lights are allowed provided that pilot lights comply with the relevant standard, if any.

Plugs and fixed or portable socket-outlets complying with this standard are suitable for use at ambient
temperatures not normally exceeding 25℃, but occasionally reaching 35℃.

NOTE 4 Socket-outlets complying with this standard are only suitable for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding temperature exceeds 35℃

In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous
locations, for example where explosions are liable to occur, special constructions may be required.

Part 2：Definitions

For the purposes of this part of IEC 60884, the definitions given in IEC 60050(151) as well as the following definitions apply.

2.1 plug
accessory having pins designed to engage with the contacts of a socket-outlet, also incorporating means for the electrical connection and mechanical retention of flexible cable

2.2 socket-outlet
accessory having socket-contacts designed to engage with the pins of a plug and having terminals for the connection of cable

2.3 fixed socket-outlet
socket-outlet intended to be connected to fixed wiring

2.4 portable socket-outlet
socket-outlet intended to be connected to, or integral with, the flexible cable and which can easily be moved from one place to another while connected to the supply

2.5 multiple socket-outlet
combination of two or more socket-outlets

2.6 socket-outlet for appliances
socket-outlet intended to be built in, or fixed to, appliances

2.7 rewirable plug or rewirable portable socket-outlet
accessory so constructed that the flexible cable can be replaced

2.8 non-rewirable plug or non-rewirable portable socket-outlet
accessory so constructed that it forms a complete unit with the flexible cable after connection and assembly by the manufacturer of the accessory

3 General requirements
Accessories and surface-type mounting boxes shall be so designed and constructed that, in normal use, their performance is reliable and without danger to the user or the surroundings within the meaning of this standard.

Compliance is checked by meeting all the relevant requirements and tests specified.

Part 3：Protection against electric shock
– Shuttered socket-outlets shall, in addition, be so constructed that live parts are not accessible without a plug in engagement, with the gauges shown in figure 10.
– The gauges shall be applied to the entry holes corresponding to the live contacts only and shall not touch live parts.
– To ensure this degree of protection, socket-outlets shall be so constructed that live contacts are automatically screened when the plug is withdrawn.
– The means for achieving this shall be such that they cannot easily be operated by anything other than a plug and shall not depend upon parts which are liable to be lost.
– An electrical indicator with a voltage between40V and 50 V included is used to show contact with the relevant part.

A steel gauge, according to figure 10, is then applied with a force of 1 N and in three directions, for approximately 5 s in each direction, with independent movements, withdrawing the gauge after each movement.

For socket-outlets with enclosures or bodies of thermoplastic material, the test is made at an ambient temperature of (35 ±2) ℃, both the socket-outlets and the gauge being at this temperature.
