1 sCOPE
This Standard applies to socket-outlet adaptors, as defined in Clause 4, and intended for useat low or extra-low voltage.
NOTE:As of 1 November 1990，Australian regulatory authorities will not approve rewirablesocket-outlet adaptors.
APPLICATION
2.1 General requirements of AS/NZS 3100
This Standard shall be read in conjunction with AS/NZS 3100 and the appropriateprovisions of AS/NZS 3100 shall apply to the construction of a socket-outlet adaptor andthe insulation and safeguarding of parts which normally carry current.
2.2Specific requirements of this Standard
socket-outlet adaptor shall be deemed to comply with this Standard only if it complieswith all requirements of this Standard and passes the specified tests.

4DEFINITIONS
For the purpose of this Standard the definitions below apply.4.1Non-rewirable socket-outlet adaptor
A socket-outlet adaptor so constructed that it forms an integral unit with any flexible cableor cord, such that——
(a)any flexible cable or cord cannot be detached from the accessory without making the
accessory useless;or
(b)any flexible cord cannot be replaced by hand or by using a general purpose tool.
4.2Plug portion
The portion of the socket-outlet adaptor which carries the pins intended for making adetachable connection with the contacts of a socket-outlet. For socket-outlet adaptorsincorporating flat-pins, the ‘plug portion’includes all parts dimensioned in accordance withAS/NZS 3112.
4.3Rewirable socket-outlet adaptor
A socket-outlet adaptor so constructed that any flexible cable or cord can be replaced.4.4Socket-outlet adaptor
An accessory for insertion into a socket-outlet and containing metal contacts,toaccommodate one or two plugs, or a flexible cord and one plug.
4.5Socket portion
The portion of the socket-outlet adaptor which carries the contacts intended for making adetachable connection with the pins of a plug.
5 PROHIBITED FEATURES
Socket-outlet adaptors shall not—
(a)have more than two outlets, the term ‘outlet’being deemed to include facilities for
the connection of a flexible cord;
(b)have more than one outlet for a flexible cord;
(c)have an outlet in the form of a lampholder;
(d)be capable of insertion in a lampholder;
(e)incorporate a plug portion having only two pins and an outlet providing for the connection of other than a 2-pin plug or a 2-core flexible cord;
(f) incorporate a plug portion having an earthing pin and an outlet not provided with anearthing terminal or earthing contact for each plug configuration able to be used withthe adaptor;
(g)incorporate any fuse or thermal overload device;
(h)have an outlet providing for the connection of a plug having a current rating
exceeding that of the plug portion of the adaptor;
(ihave an outlet with a current rating exceeding 20 A;
jhave an outlet with a voltage rating exceeding low voltage; and
(k)have an outlet with polarity differing from that of the plug portion of the adaptor.6EXTRA-LOw VOLTAGE TYPES Extra-low voltage socket-outlet adaptors are not required to comply with Clauses 15 and 17.7 PLUG AND SOCKET PORTIONS The socket portion of the adaptors shall comply with the appropriate requirements ofAS/NZS 3112.
8 INSULATING MATERIALS The insulating portions of a socket-outlet adaptor shall consist of—
(a) insulating material having properties not inferior to those of Class 80 moulding complying with AS/NZS 3112;or
(b) ceramic material of a type such that, after immersion in water for 48 h and after all visible drops of water have been removed from the surface by means of a clean dry cloth, it shall not have increased in mass by more than 2 percent. In addition, all insulating portions, except ceramic, of a socket-outlet adaptor shall comply with the requirements of AS/NZS 3112 for ignitability and combustion propagation.
9 TERMINALS AND INTERNAL CONNECTIONS
9.1 Material Terminals and internal connections intended primarily for carrying current shall be of suitable corrosion-resisting metal of sufficient hardness and rigidity for the intended application.
