3.1.11.2 Physical requirements of the jacket before aging. The outer jacket removed from the cable or
taken from a slab section shall meet the following requirements performed at an ambient temperature of
18 to 32 °C (see 4.6.11.2).
a. Tensile strength. - The jacket specimen shall have a tensile strength of not less than
2,000 pounds per square inch of original cross sectional area at rupture.
b. Elongation. - The jacket specimen shall have an elongation of 350 percent minimum at
rupture.
3.1.11.3 Physical requirements of the jacket after aging. The jacket specimen obtained as indicated in
3.1.11.2 shall meet the following physical requirements when tested at a temperature of 18 to 32 °C after
the specimen has been subjected to the aging process specified in 4.6.11.3.
a. Tensile strength. The jacket specimen shall have a tensile strength of not less than 90
percent of the value obtained on an adjacent specimen prior to artificial aging.
b. Elongation. The aged jacket specimen shall have an elongation of the 2 inch gauge marks at
rupture, not less than 90 percent of the value obtained on an adjacent specimen prior to
artificial aging.
3.1.12 Identification marking. The cable shall be marked on the outside with an inked marking. The
outer surface of the cable shall be smooth and free from raised or indented markings. All letters and
numbers shall be of the same height; inked markings shall be clear and legible. The inked marking shall
consist in succession of the nomenclature, the specification number, manufacturer's company initials and
year of manufacture +30 days. Three to five letter spaces shall be allowed between them. The marking
shall be repeated at intervals along the cable not to exceed 1 foot (see 4.6.12).
3.2 Electrical requirements (see 4.7).
3.2.1 DC resistance. The direct current resistance of each conductor shall not exceed 62Ω per 1000 ft.
loop at 20 °C (see 4.7.1).
3.2.2 Dielectric strength. There shall be no evidence of voltage drop when tested in accordance with
3.2.3 Insulation resistance. When tested in accordance with 4.7.3 the insulation resistance shall be not
less than 10,000 megohms per 1,000 feet. of cable at 20 °C.
3.2.4 Conductor resistance unbalance. The conductor resistance unbalance for each pair shall not
exceed 4 percent except that not more than 2 pairs per length may have values between 4 and 8%. The
conductor resistance unbalance in each pair is expressed as a percentage as follows: (see 4.7.4).

3.2.5 Mutual capacitance. In each length of cable, the mutual capacitance of each pair measured at
60 °F at a frequency of 1000+100Hz shall not exceed 0.090 µF per mile, when tested in accordance with
3.2.6 Capacitance unbalance. In every length of cable, the 1000Hz pair to pair capacitance unbalance
shall not exceed 160 micro-microfarads for any length of 1,000 feet or less. The average pair to pair
capacitance unbalance shall not exceed 40 pF for any length of 1000 feet or less. For other lengths of
