4.2.4 Thickness and centering
4.2.4.1 The average and minimum thickness of the insulation shall be as shown in Tables 9 — 12. Compliance shall be determined in accordance with the test. Thickness, in UL 2556.
4.2.4,2 The insulation shall have a circular cross-section, wTth the insulation applied concentrically about the conductor and fitting tightly on the conductor or over any separator.
4.2,5 Physical properties of insulation
4,2.5.1 General
4.2,5.1.1 The tensile strength and ultimate elongation of the insulation, before and after aging. shall be as specified in Table 13.
4.2.5,2 Test requirement
4.2.5.2.1 Compliance with 4.2.5,1.1 shall be determined in accordance with the test, Physical properties
(ultimate elongation and tensile strength), in UL 2556.
4.2.5.3 Evaluation of alternative insulation materials for use in this Standard (see Appendix C)
4.2.5.3.1 Alternative insulation matenals for products shall be evaluated in accordance with the test, Dry temperature rating of new materials (long-term aging test. In UL 2556.
4.2.5.3.2 Materials having characteristics different from those specified in Table 13 shall be evaluated tor the requested temperature rating in accordance with 5.15. To be evaluated, materials shall have an initial absolute minimum tensile strength of not less than 6.8 MPa (1000 lbffin2), and an absolute minimum elongation of 100 percent before aging.
4.2.5.3.3 The temperature rating and thickness of those materials having characteristics different from those specified in Table 13 shall be as required for the specific thermoplastic-insulated wire or cable type. The electrical, mechanical, and physical characteristics of the wire or cable using these materials shall be such that the materials meet the specified requirements for the temperature rating.
4.2.5.3.4 Insulation material complying with 42.5.3.2 shall then be evaluated to establish requirements for its specific physical properties in Table 14.
4.2.4.1 The average and minimum thickness of the insulation shall be as shown in Tables 9 — 12. Compliance shall be determined in accordance with the test. Thickness, in UL 2556.
4.2.4,2 The insulation shall have a circular cross-section, wTth the insulation applied concentrically about the conductor and fitting tightly on the conductor or over any separator.
