2.2.5 Double insulation Insulation comprising both basic insulation and supplementary insulation.
2.2.6 Integral switching device A mechanical switching device constructed as a part of an accessory within the scope of this Standard.
2.2.7 Interlock A device, either electrical or mechanical, that prevents the contacts of a plug from becoming live before it is in proper engagement with a socket-outlet or connector, and which either prevents the plug from being withdrawn while its contacts are live or makes the contacts dead before separation.
2.2.8 Mechanical switching device A switching device designed to close and open one or more electric circuits by means of separable contacts.
2.2.9 Non-rewireable plug or connector An accessory so constructed that the flexible cable cannot be separated from the accessory without making it permanently useless.
2.2.10 Plug and socket-outlet A means enabling the connection at will of a flexible cable to fixed wiring. It consists of the following two parts:
(a) Socket-outlet The part intended to be installed with the fixed wiring.
(b) Plug The part integral with, or intended to be attached to, the flexible cable connected to the equipment or to a connector.
2.2.11 Rated current The current assigned to the accessory by the maker in accordance with Clause 5.2.
2.2.12 Rated voltage The voltage assigned to the accessory by the maker in accordance with Clause 5 and to which dielectric tests, clearances and creepage distances are referred.
2.2.13 Reinforced insulation A single insulation system applied to live parts, which provides a degree of protection against electric shock equivalent to double insulation under the conditions specified in this Standard.
NOTE: The term ‘insulation system’ does not imply that the insulation is to be one homogeneous piece. It may comprise several layers which cannot be tested singly as supplementary or basic insulation.
2.2.14 Retaining device A mechanical arrangement that holds a plug or connector in position when it is in proper engagement and prevents its unintentional withdrawal.
2.2.15 Rewireable plug or connector An accessory so constructed that the flexible cable can be replaced.
2.2.16 Supplementary insulation An independent insulation applied in addition to the basic insulation, in order to ensure protection against electric shock in the event of a failure of the basic insulation.
2.2.17 Switched socket-outlet A socket-outlet with an associated switching device to disconnect the supply from the socket-outlet contacts.
2.2.18 Terminal A conductive part provided for the connection of one or more conductors to an accessory.
2.2.19 Type test A test of one or more devices made to a certain design to show that the design meets certain specifications.
3 GENERAL REQUIREMENTS Accessories shall be designed and constructed so that in normal use their performance is reliable and there is no danger to the user or surroundings. In general, compliance is checked by carrying out all the specified tests.
4 GENERAL NOTES ON TESTS
4.1 Type of tests Tests according to this Standard are type tests. If a part of an accessory has previously passed tests for a given degree of severity, the relevant test shall not be repeated if the severity is not greater.
4.2 Sampling Unless otherwise specified, the samples are tested as delivered and under normal conditions of use, at an ambient temperature of 20 ±5°C; the tests are made at rated frequency. 4.3 Order of tests Unless otherwise specified, the tests are carried out in the order of the clauses of this Standard.
4.4 Number of samples One sample is subjected to all the tests; however, separate samples may be used for the tests of Clauses 18, 24, 25, 27 and 28. NOTES: 1 Attention is drawn to the additional ‘new’ plug required by Clause 15. 2 A sample of the matching accessory is required for test purposes.
4.5 Pass criteria Accessories are deemed not to comply with this Standard if the sample fails any of the tests.
4.6 Conductors When tests are carried out with conductors, they shall be copper and shall comply with either the AS/NZS 5000 series or AS/NZS 3191, as appropriate.
