澳洲AS/NZS 3112条款3.14.5节插座温升测试用插头|SAA插座温升测试治具|Test plug of the temperature rise test for socket-outlets of AS/NZS 3112 clause 2.8

Socket-outlets shall be tested using a test plug with brass pins having the specified dimensions of Figure 2.1. The plug shall be inserted into the socket-outlet and 1.1 times rated current shall be passed until a constant temperature has been attained. The temperature shall be determined by means that have a negligible effect on the temperature being determined. For multi-outlet socket-outlet units, the test shall be conducted on one outlet of each type, the outlet(s) not under test being maintained in a no-load condition.

For the purpose of this test, the connecting cables shall be unsheathed Type V75 cables, the size of which shall be determined from Table 3.3. Plugs shall have at least 1 m of cable and socket-outlets shall have at least 2.5 m of cable. The cables shall be stripped to the minimum length required to effect the intended connection of the socket-outlet. The socket-outlet shall be mounted in an appropriate metal wall box installed in a draught-free position, and the cables supplying the socket-outlet shall be enclosed for a distance of 1 m in conduit terminated at the wall box. The terminal screws or nuts shall be tightened with a torque equal to two thirds of that specified in the test for screw threads and fixings in AS/NZS 3100.

NOTE: An appropriate metal wall box is described in Clause 3.14.1.

The temperature rise of any terminal or contact shall not exceed 45 K.

For the purpose of this test, the ambient temperature shall be maintained at 20 ±5°C.
