6 General conditions for type testing

6.1 All tests shall be type tests.

Unless otherwise specified in this part of BS 1363 the socket-outlets shall be tested as delivered by the manufacturer or responsible vendor and under normal conditions of use, at an ambient temperature of 20 ℃ ±5 °C, after being conditioned at normal laboratory temperature and humidity levels for at least 4 days.

Unless otherwise stated by the manufacturer, flush mounted socket-outlets shall be tested when mounted on a corresponding box conforming to the dimensional requirements of BS 4662:2006+A1:2009,the fixing screws being tightened with a torque of 0.6 Nm ±10%.

Other types shall be mounted according to the manufacturer’s instructions. Socket-outlets having a declared IP rating shall be tested as a complete assembly (socket-outlet and enclosure) when mounted in accordance with manufacturer’s instructions and conditions of use.

Individually protected socket-outlets (IPS) shall be tested as delivered.
Individually protected socket-outlets (IPS) shall be tested as fixed socket-outlets unless otherwise specified in the particular test.

The box or enclosure shall be as specified by the manufacturer.
NOTE 1 Individually protected socket-outlets (IPS) are intended for incorporation into equipment or enclosures such as those for use in electrical systems within the scope of BS 6396. IPS may be either fixed or portable, subject to manufacturer’s instructions, integral with the complete assembly, (eg. furniture), in a surface accessory, or they may comprise a flush accessory mounted in a corresponding box.

The socket-outlets used for the tests shall be representative of normal production items in respect of all details which might affect the test results.

Non-rewirable socket-outlets shall be supplied with an appropriate flexible cable which shall be at least 1 m long, Socket-outlets shall be deemed to conform if no sample fails in the complete series of tests given in Table 1.

If one sample fails in the complete series of tests given in Table 1,then socket-outlets of that type shall be deemed to have failed to conform to this part of BS 1363, unless the socket- outlet is shown to be not representative of normal production or design, in which case a further type test sample shall be submitted to the test or tests in that particular group. If there is no failure in this retest then socket-outlets of that type shall be deemed to conform to this part of BS 1363.
If more than one sample fails in the complete series of tests given in Table 1 then socket-outlets of that type shall be deemed not to conform to this part of BS 1363.
For type testing, all tests have been included in the test schedule and shall be performed in the specified order.
NOTE 2 References to carrying out specific tests in various clauses are not intended to indicate a sequence of testing different to that in the schedule and should not be conducted as separate additional tests.

6.2 All inspections and tests, of any one classification (see Clause 7), shall be carried out as specified in the clauses listed in Table 1 on the number of samples in the sample column and in the order given.
6.3 Gauges in accordance with Figure 11, Figure 12,Figure 14, Figure 16a) and Figure 16b) shall be considered to conform to the dimensional requirements if the results of the measured values are within the specified dimensions and the uncertainty of measurement at not less than 95% confidence level does not exceed ±0.005 mm.
