The conductors then shall be tied together at each end and loaded with SPECIFICATION 44, ISSUE 7 Page 9 of 12 the weight specified in the applicable specification sheet. The test mandrel shall be as specified in the applicable specification sheet. 4.4.2 Bend Test At a temperature maintained between 20 and 25°C, one end of the cable specimen shall be secured to the mandrel and the other end to the load weight specified in the applicable specification sheet. The mandrel shall be rotated until the full length of the specimen is wrapped around the mandrel and is under the specified tension with adjoining turns in contact. The mandrel then shall be rotated in the reverse direction until the full length of the specimen which was outside during the first wrapping is now next to the mandrel. This procedure shall be repeated until two bends in each direction have been formed in the same section of the specimen. The specimen then shall be examined visually for cracks. 4.4.3 Examination of Product All samples of wire and cable shall be examined to determine conformance with this specification and the applicable specification sheet with regard to requirements not covered by specific test methods. 4.4.4 Immersion Finished cable shall be tested in accordance with the procedure specified in AS81044, using the bend test of 4.4.2 herein. The voltage withstand test of 4.4.10 herein shall then be conducted on shielded and jacketed specimens only. Cable specimens shall be prepared by removing 2 inches (51 mm) of the jacket from each end of a 24-inch (610-mm) length of each specimen. When applicable, the shield then shall be pushed back and formed into a pigtail at each end of the specimen and 1 inch (25 mm) of insulation from each conductor shall be removed from each end of the specimen. 4.4.5 Jacket Concentricity The concentricity of the cable jacket shall be determined by first locating and recording the minimum wall thickness measured on a cross section of the jacket. The maximum wall thickness of this same cross section of the jacket shall be measured and recorded. The wall thickness shall be the radial distance between the inner and outer rim of the jacket as measured under suitable magnification. The ratio of the minimum wall thickness to the maximum wall thickness, times 100, shall define the percent concentricity. 4.4.6 Jacket Elongation and Tensile Strength The elongation and tensile strength of the jacket shall be determined in accordance with the procedure specified for insulation elongation and tensile strength in AS81044. 4.4.7 Jacket Flaws Finished shielded and jacketed cable shall be tested in accordance with the jacket flaws test of WC 27500, or the procedure of the impulse dielectric test of AS81044 with the shield grounded at one or both ends. © 2005 -2022 TE Connectivity Ltd. family of companies.

Temperature, mandrel diameter and test weight shall be as specified in the applicable specification sheet. After examination for cracks, shielded and jacketed specimens shall be subjected to the voltage withstand test of 4.4.10 herein. 4.4.9 Radiation Resistance A 10-foot (3-m) specimen of the finished wire or cable shall be subjected to the electron radiation dosage specified in the applicable specification sheet at an average rate of between 5 and 10 megarads (50 and 100 kGy) per minute. Following exposure, the center portion of the specimen shall be wound around the mandrel as specified in the applicable sheet. The ends of the specimen shall extend at least 6 inches (152 mm) beyond the wound portion. For finished wire and shielded and jacketed specimens, the specimen shall then be removed from the mandrel without unwinding and shall be subjected to the voltage withstand test of 4.4.10. For jacketed only specimens, the specimen shall be examined for cracks while still on the mandrel. 4.4.10 Voltage Withstand Test (Post Environmental) The uninsulated ends of the specimen shall be attached to an electric lead. The specimen shall be immersed in a 5-percent, by weight, solution of sodium chloride in water at 20 to 25°C, except that the uninsulated ends and 1.5 in. (38 mm) of insulated wire or cable at each end of the specimen shall protrude above the surface of the solution. After immersion for 5 hours, the voltage specified in the applicable specification sheet at 60 Hz shall be applied between the conductor or the shield, as applicable, and an electrode in contact with the liquid. The voltage shall be gradually increased at a uniform rate from zero to the specified voltage in 0.5 minute, maintained at that voltage for a period of 5 minutes for finished wire specimens and 1 minute for finished cable specimens, and gradually reduced to zero in 0.5 minute. 4.4.10.1 Inner Jacket For accelerated aging and life cycle cable specimens only, containing a jacket between two shields, the voltage withstand test of 4.4.10 shall additionally be conducted on the inner jacket with the voltage as specified in the applicable specification sheet being applied between the two shields. 5.
