Copyright Electronic Components, Assemblies the Crystalline propylene/ethylene copolymer material shall be tested at -YO Ie l 0 C with the mandrel diameter equal to the outside diameter of the insulated conductor. 3.3.2.3 Shrin kback: A minimum of one sample of each insulated wire from the cable shall be tested. Immediately prior to testing, specimens 70 cm (8 in.) long shall be cut from the center of a 1.5 m (5 ft) length and then reduced to 15 cm (6 in.) by trimming each end of the specimen. The 15 cm ( 6 in.) specimens shall be placed in a convection type circulating.air oven for 4 hours at the temperatures indicated. Shrinkback is defined as a total shrinkage of the insulation from both ends of the specimen. Material Temperature polyethylene 115 f l0C crystalline propylene/ethylene 130 f l0C copolymer 3.3.3 ANTIOXIDANT TESTS Test for residual antioxidant activity after processing conduct using the following cable conditioning and insulation test procedures. A short length section, approximately 30 cm (i ft), of cable shall be sealed at the ends And placed in an oven at a temperature of 68 f l 0 C for 8 hours for conditioning. The sample will then be allowed to equilibrate to room temperature for a total of 24 hours. After w - Copyright Electronic Components, Assemblies allowed t o equilibrate 24 hours, and tested again according for bonding strength as described in 1.5.8. The peel strength t o metal shall not show any decrease from the value in 1.5.8. -7 /-7 Copyright Electronic Components, Assemblies the depth of the controlled imperfection shall be proportional t o the jacket thickness, and the stress cracking reagent shall be a 10 percent solution (by volume) of “Igepal“ CO-630. Shrinkback: Slab specimens shall be cut from the jackets 50 mm (2 in.) long, 13 mm (0.5 in.) wide, and the same thickness as the jacket. The slab specimens shall be placed i n a convection type circulating air oven operating a t a temperature of 100 k l 0 C for a 4 hour period. Impact: A jacketed cable of approximately 40 c m (15 in.) in length is secured across t h e bottom of a tube 32 mm (1.25 in.) in diameter. This assembly is placed on a firm surface in a cold chamber a t a temperature of -20 2 2OC for 4 1 hours after which a weight is released a t the top of the tube. The length of the tube and the weight that'.is used shall be such that a 4 n-m (3 ft;+lb) impact is delivered to the jacketed 7 Copyright Electronic Components, Assemblies I JI I min max I I c m I I I I i 13 i 15 i 444 i para i 444 para 4.5 i l I I I 3.4.2 I 1 3.4.2 I I I ! !
