TESTS

General

Plug portions of equipment shall be subjected to the following tests and unless stated otherwise, shall comply with the requirements specified in Section 2 for each test. The number of test samples shall be in accordance with Table 2.2.
Conformance for detachable plug portions shall be established by assessment with the plug portion fully assembled with the equipment.

High voltage test

The requirements of Clause 2.13.3 are applicable unless requirements are contained in the relevant product standard.
Mechanical strength of pin tests
Tumbling barrel test
The tumbling barrel test is applied to determine the mechanical strength of the plug pins.

Three samples that have not been subjected to any previous test are tested to the requirements of Clause 2.13.7.1, however the test is modified as follows:
A sample is dropped-
(a) 500 times if the mass of the specimen does not exceed 250 g. The pins being straightened after each 100 drops and at the completion of the test to pass through the appropriate gauge of Figure A1, Figure B1 or Figure F1; and
(b)250 times if the mass of the specimen exceeds 250g. The pins being straightened after each 25 drops and at the completion of the test to pass through the appropriate gauge of Figures A1, Figure Bl or Figure F1.
Following each test the samples shall comply with Clause 2.13.7.1.

Pin bending test

The pins of the plug portion of three samples not subjected to any previous tests shall be tested for conformance with the pin bending test of Clause 2.13.7.2.

Temperature rise test

The relevant requirements of Clause 2.13.8 are applicable for the temperature rise test, except that the test current shall be that specified in the relevant product standard.
The temperature rise of the pins shall not exceed 45 K irrespective of the temperature rise of parts specified in end-product standards.
For detachable plug portions the temperature rise of terminals and contacts shall not exceed 45K.

Securement of pins of the plug portion
The requirements of Clause 2.13.9 are applicable for the securement of pins.

Tests on the insulation material of insulated pin-plug portions
The requirements of Clause 2.13.13 are applicable for insulating material of insulated plug pins.

Equipment with a plug portion intended to be supported by the contacts of a socket-outlet
Equipment with a plug portion intended to be supported by the contacts of socket-outlets shall not impose undue strain on those socket-outlets.

Unless requirements are contained in the relevant product standard, conformance is checked by inserting the equipment with a plug portion, as in normal use, into a flush-mounting combination switch socket-outlet complying with this Standard. The socket-outlet being pivoted about a horizontal axis through the centre-lines of the contact apertures at a distance of 8 mm behind the engagement face of the socket-outlet (see Figure J4). The additional torque, which has to be applied to the socket-outlet to maintain the engagement face in the vertical plane, shall not exceed 0.25 Nm.

For equipment with a plug portion having an outlet in the form of a flexible cord, the test is conducted with the centre-line of the axis of pivot of the socket-outlet located at a point 500 mm above a horizontal surface. The flexible cord is allowed to hang freely from the equipment with that flexible cord in excess of 500 mm resting on the horizontal surface during the test.
