8.10.2 Insulation resistance for all indoor cables
8.10.2.1 The insulation resistance between each insulated conductor and between the insulated conductors and any other conductive components and ground shall be not less than 2.5 Mohm°1000 ft (0.76 Gohm.rn) at 15°C (59°F) when a specimen 01 the finished cable at least 50 ft (15 m) in length is tested in air after conditioning for at least 6 hours and immediately following the dielectric strength test described in 8.9.
8.10.3 Test method
8.10.3.1 Compliance with all insulation resistance tests shall be determined in accordance with the test, lnsulaton restslance, and Annex E (Determination of temperature correction factor) in UL 2556.
8.11 Durability of ink printing
8.11.1 Surface-printed legends shall be complete and legible after two samples have been tested in accordance with the test, Durability of ink printing, in UL 2556. One sample shall be conditioned at the dry rated temperature of the sample for 24 hours.
8.12 Capacitance and relative permittivity
8.12.1 The insulation, without the protective covering, of wet-rated single-conductor cable and of the indrviduai single conductors of multiple-conductor cable immersed in water at the rated temperature of 75°C or 90°C (167 or 194°F), shall comply with each of the following:
a) The relative permittivity determined after immersion for 24 hours shall be 6.0 or less for EP and XL insulations, and shall not be more than 10 for TPE insulation.
b) The capacitance for TPE. EP, and XL insulations after immersion for 14 days shall be no more than 10 percent higher than the capacitance after a 24 hour immersion.
C) The capacitance determined for EP and XL insulations after a 14 day immersion shall be no more than 4 percent higher than the capacitance determined after immersion for 7 days for EP and XL insulations and not more than 5 percent higher for TPE insulation.
8.12.2 Compliance shall be determined in accordance with the test. Capacitance and relative permittivity. in UL 2556.
8.13.3 Maximum acceptable rate of decrease
8.13.3.1 During the extended immersion, the maximum decrease in insulation resistance per week, as determined from a curve (drawn to represent the average of actual values), for every continuous period of 3 weeks dunng the latter half of the specified Immersion lime shall be not more than 4 percent if and while the insulation resistance is 10 MQ1000 ft (3 Gc.m) or more, and shall be not more than 2 percent if the insulation resistance is less man io Mci.i000 ft (3 Gfl.m), but more than the value calculated.
8.13.3,2 Any coil that shows a greater percent decrease in insulation resistance than those indicated in
8.13.3.1 dunng the extended period of time in the water tank shall be allowed to be tested foi- additional one week periods in the water tank and judged on the basis of the results for the lasI 6 week period in the water tank, provided that the final insulation resistance is not less than calculated.
8.13.3.3 Compliance with 8.13.2.1 — 8.13.3.2 shall be determined in accordance with the test, Long-term insulation resistance (Method 1), in UL 2556
8.14 Weather resistance — cables marked sunlight resistant
8.14.1 After conditioning for 720 hours in a xenon arc weatherometer as described in the test, Weather (sunlight) resistant, in UL 2556. the outermost layer shall:
a) Show no cracks when wound one complete turn around a mandrel having a diameter as shown in Table 8.5 while at a temperature of minus 30 ±10C (22 ±1.8°F) for a period of 1 hour. During the bending, the conditioned surface shall be opposite the surface contacting the mandrel. The specimen shall be allowed to rest 16 to 96 hours at room temperature before conducting the cold bend test.
b) Retain an average tensile strength and elongation of not less than 80 percent of the original values. Conditioned and unaged sets (five specimens each) shall be allowed to rest 16 to 96
hours at room temperature, followed by physical properties testing. Conditioned surfaces required to be die-cut shall not be bulled or skived away,
8.15 Swell lng and blistering of thermoset jackets — Types W, G, G-GC marked sunlight resistant
8.15.1 The jacket of a 33 feet (10 m) length of finished cable shall neither blister nor increase the cable diameter by more than 20 percent after the specimen of finished cord has been immersed continuously in water for 2 weeks at 50 ±1°C (122 ±1.8°F). Compliance shall be determined with the apparatus and in accordance with the test, Swelling and blistering when immersed in liquid, in UL 2556.
