- 6.1 A manufacturer or responsible vendor who claims conformity to this standard for any product, shall submit a representative type test specimen of that product to the relevant tests of this standard in the order specified in 6.2. The tests shall be ma
- 6.2 A total of at least nine specimens of socket-outlet, of any one type, shall be submitted to inspection and tests against the requirements of the following clauses:
- 6.3 Unless otherwise specified in this standard, the socket-outlets shall be tested (as delivered by the supplier) under the conditions specified in 4.2 of BS 6312-2.1:1994.
- 7 Construction [Go to Page]
- 7.1 The minimum size of flush socket-outlet plates constructed either of insulating material or of metal, or a combination of both, and which are intended for mounting on size UA1 boxes as specified in BS 4662, shall be 82.5 mm ° 82.5 mm.
- 7.2 Flush-mounted socket-outlets intended for mounting on size UA1 boxes as specified in BS 4662 shall have provision for two M3.5 fixing screws at centres of (60.3 ± 0.2) mm.
- 7.3 Surface mounted socket-outlets shall be provided with a box or enclosure to ensure proper seating on a flat surface, the box having a minimum of two holes for mounting which will accept No. 6 wood screws conforming to BS 1210:1963.
- 7.4 For panel mounted socket-outlets, the manufacturer/supplier shall specify the panel thickness and method of mounting. The dimensions of the panel cut-out shall be not less than those shown in Figure 1. [Go to Page]
- Panel cut-out dimensions
- 7.5 The construction of the socket-outlet shall be such that when a mating plug is withdrawn from it, the socket contacts are automatically screened by a shutter.
- 7.6 For multiple socket-outlets incorporating two or more sockets, the pitch between adjacent sockets shall be not less than 24 mm.
- 7.7 The mounting of a socket within a socket-outlet shall be such that the maximum dimension from the front face of the socket beneath the shutter to the front face of the socket-outlet immediately adjacent to the shutter is 5.5 mm.

- 8.1 Primary surge protected socket-outlets shall include the following components, configured as shown in Figure 2a):
- 8.2 Unprotected socket-outlets shall include the same components as those specified in 8.1, with the exception of the voltage surge protector. The circuitry shall be configured as shown in Figure 2b).
- 8.3 Secondary socket-outlets shall not include auxiliary components and shall be configured as shown in Figure 3.
- 8.4 Any PCB used for the interconnection of the components shall be based on BS EN 123000.
- 8.5 The assembled socket-outlet shall meet the requirements of this specification over the range of -10 °C to +40 °C and continue to operate correctly after being subject to the environmental conditioning detailed in A.3. [Go to Page]
