4.14.3 Requirements for adjusting devices are given below.
a) 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:
The adjusting device, equipped with the appropriate cable or cord shall be operated in accordance with 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 heat appreciably and shall not exceed 600 cycles per hour.
For electro-mechanical contact systems, this test is conducted simultaneously with the electrical connection test of 4.11.6.
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.
b) Luminaires with a means of adjustment intended to be installed within arms reach, shall allow the operation of its intended function without impairing the stability of the luminaire or causing deformation of any part of the construction, nor cause injury due to temperatures above those specified in Table 12.1.
Compliance is checked by manipulating or handling the luminaire, by the means of adjustment as expected to represent normal use and by measurement of the temperatures during the test of 12.4.
c) For luminaires intended to be mounted within arms reach, the space surrounding any means of adjustment, except the light beam aperture, up to 5 cm away from the means of adjustment in any direction, shall comply with the temperature limits for the means of
adjustment, as specified in Table 12.1. The same temperature limits apply also to any means of adjustment which are lit after the positioning of the luminaire light beam aperture.
Compliance is checked by positioning the luminaire light beam aperture and by measurement of the temperatures during the test of 12.4.
