(i) Tests on any other size of cable specifically qualify that size only.
(ii) Changes in the flamelfire barrier (i.e. material type or construction) require a separate qualification using 35 mm2 cables in the trefoil configuration.
(iii) Any metallic layer shall be earthed during the tests.
(iv) Changes in cable voltage rating require a separate qualification using 35 mm2 cables without serving arranged in a trefoil configuration.
(v) Testing of a cable ithout serving qualifies a cable with serving.
(vi) Changes in the construction of the metal sheath (e.g. from drawn tube to seamed construction) require a separate qualification using a 35 mm2 cable without serving arranged in a trefoil configuration.
(1) For qualification of Group 6. the specimens to be tested shall be a single 1.5 mm three-core circular cable without serving. This test shall qualify all other multicore cable sizes, and qualifies the range of constructions such as the 2C, 3C. 4C. and any other multicore. with the following exceptions:
(i) Tests on any other size of cable specifically qualit that size only.
(ii) Changes in the flame/tire barrier (i.e. material type or construction) require a separate qualification using a single 1 .5 mm three-core cable without serving.
(iii) The cable sheath shall be earthed during the tests.
(iv) Changes in cable voltage rating require a separate qualification using a single 1.5 mm2 three-core cable without serving.
(v) Testing of a cable without serving qualities a cable with serving.
(vi) Changes in the construction of the metal sheath (e.g. from drawn tube to seamed construction) require a separate qualification using a single 1.5 mm2 three-core circular cable without serving.
A4.2.2 Arrangement of specimens
Test specimens shall be arranged so that there are a minimum of two changes of direction. each not less than 900. Bends in cables shall be made at the minimum bending radius recommended by the manufacturer. In the case of single-core cables in trefoil, the minimum bending radius shall apply to the cable positioned on the inner curvature of the trefoil arrangement.
A4.3 Busavs
A4.3.I Specimens to he tested
For each type of busway. one specimen of the smallest conductor cross-sectional area (a type is classified according to its materials and methods of construction). These tests shall qualify all other husway sizes of the same type of construction comprising—
(a) more conductors with the same cross-sectional area or
(b) larger conductors with the same number of cores.
