b. Aging requirements:
(1) After air oven test at a minimum of 150 ºC for 168 hours:
(a) Tensile strength in percent of unaged value, 75 percent minimum.
(b) Elongation at rupture in percent of unaged value, 65 percent minimum.
2
(2) After air pressure heat test for 42 hours at 80 lbs/in and 127 ºC:
(a) Tensile strength in percent of unaged value, 75 percent minimum.
(b) Elongation at rupture in percent of unaged value, 75 percent minimum.
3.3.2.5 Ozone resistance. The cable insulation shall be resistant to ozone attack.
3.3.2.6 Moisture absorption. The moisture absorption properties of the cable insulation shall be as
follows:
Increase in capacitance:
1 to 14 days: 3 percent maximum
7 to 14 days: 1.5 percent maximum
3.3.2.7 Cold bend. The cable insulation shall not crack as a result of bending at a radius of 2.5 times
the cable diameter when in an ambient temperature of -40 ºC or less.
3.4 Performance.
3.4.1 High temperature. The cable shall be resistant to high temperatures encountered while in
storage and under service conditions. When in an ambient temperature of 71 ºC, a full reel of cable shall
not suffer permanent set to any portion of the cable or show evidence of insulation deterioration.
3.5 Surface marking on cable. The manufacturer's name and contract number shall be legibly
marked on the surface of all cable. The markings shall be of paint or ink applied at intervals not
exceeding 10 feet. The markings shall be durable and not readily smeared during handling of the cable.
3.6 Workmanship. Workmanship shall be of the quality necessary to produce cable free from all
defects which affect proper functioning in service. The exterior surface of the cable shall be smooth,
uniform, and free from splinters, ridges, grooves, indentations, and protuberances visible to the naked
eye.
3.7 Cable lengths. Except as specified in, cable shall be of one continuous 3,000-foot length, +10, -3
percent (see 6.2).
