20、ecification and a natural convection oven shall be necessary for this test. 5 Method 5.1 Procedure A specimen shall be wound round a mandrel with two layers superimposed, each consisting of six to eight coils of cable. The cable shall be wound so that the coils are in contact with one another. The e

21、nd of the conductor shall be attached to the mandrel to avoid any unwinding or detachment of coils or layers. The whole unit shall be placed in a natural draught oven at the temperature shown in the product standard for 6 h. After 6 h the unit shall be removed from the oven and cooled for at least 1

22、 h at ambient temperature. 5.2 A check shall then be made to ensure that the cable can easily be unwound from the mandrel and the coils easily separated from one another. Any bonding of layers, either along the insulation or the jacket or at the ends, shall be considered as a defect. For screened ca

23、bles, the cable components shall be easily separated. Any flaring of any layer shall also constitute a failure.
