8.1 Bending test at low temperature for insulations
This test is intended in general for cores of circular cross-section having an external diameter up to and including 12.5 mm and for sector-shaped cores when it is not possible to prepare dumb-bells. Cable Testing Equipment
If required by the standard for the type of cable, the test shall be carried out on larger cores. Otherwise, the insulation of larger cores shall be subjected to the elongation test described in Sub-clause 8.3.
8.1.2 Sampling and preparation of test pieces
Each core to be tested shall be represented by two samples of suitable length. After removal of the coverings, if any, the samples shall be used as test pieces. Cable Testing Equipment
The apparatus recommended for this test is represented in Figure 1, page 20, with explanations. It consists essentially of one revolving mandrel and guiding devices for the test pieces. Cable Testing Equipment
Other single-mandrel apparatus, substantially equivalent to the one represented in Figure 1, may also be used.
The apparatus shall be held in a suitable low temperature cabinet before and during the test.
