IEC 60598-1 Luminaries Adjusting Devices 360° Movement PLC Control Test Apparatus

Product information:

The test equipment is designed and manufactured according to clause 4.14.3 of IEC 60598-1, mainly used for the lamps adjustment devices’ torsion, and bending test of the table lamps, floor lamps and the lamps which are for professional use (such as a plotter lamps).

To verify adjusting devices or means of adjustment, for example joints, hoisting devices, adjusting brackets or telescopic tubes, shall be so constructed that cords or cables are not pressed, clamped, damaged or twisted along the longitudinal axis by more than 360° during operation.

Test principle:

Adopts the motor to drive the turntable, then simulates normal operation of lamp adjusting devices and then reset.

The adjusting devices, equipped with the appropriate cable or cord shall be operated in according with IEC 60598-1: 2014 table 4.5. A cycle of operation is a movement from one extreme of the range to the other and back to the starting position. The rate of movement shall not cause the device to hear appreciably and shall not exceed 600 cycles per hour.

Product features:

Adjusting devices and means of adjustment, for example joints, hoisting devices, adjusting brackets or telescopic tubes, shall be so constructed that cords or cables are not pressed,clamped, damaged or twisted along the longitudinal axis by more than 360° during operation. NOTE If a luminaire has more than one joint the 360° limit applies to each joint if they are not too close together. Each case needs to be judged on its own merits.
Compliance is checked by the following test:
A cycle of operation is a movement from one extreme of the range to the other and back to the starting position. The rate of movement shall not cause he device to heat appreciably and shall not exceed 600 cycles per hour.

Compliance is checked by inspection:
After the test, not more than 50 % of the strands in a conductor shall be broken nor shall there be any serious damage to the insulation, if any, of the flexible cord. The cord or cable shall be subjected to, and shall satisfy, the insulation resistance and high-voltage tests specified in Section 10.
Ball-joints and the like, where the clamping means can be adjusted, are tested with the joints only lightly clamped to avoid excessive friction. If necessary, the clamping areas are readjusted during the test. For adjusting devices that consist of a flexible tube, the range of adjustment for this test is normally 135° in both directions from the vertical. However, where this adjustment cannot be achieved without using unreasonable force, the flexible tube is bent only to the positions where it will remain by itself.
