ASTM D 4566 : 2008 : EDT 1

1.1 These test methods cover procedures for electrical testing of thermoplastic insulations and jackets used on telecommunications wire and cable and for the testing of electrical characteristics of completed products. To determine the procedure to be used on the particular insulation or jacket compound, or on the end product, reference should be made to the specification for the product.

1.2 The test methods appear in the following sections of this standard:

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Sections 6 and 37.n="top"> Fault rate test (air core only)33 Insulation resistance (IR)32 Jacket voltage breakdown rating test36 Mutual capacitance (CM)18 Mutual conductance16 Phase Constant44 Phase Delay45 Phase Velocity46 Resistance of other metallic cable elements14 Shorts test (continuity between wires of a pair)34 Structural Return Loss and Return Loss50 Unbalance attenuation (conversion losses)51 Voltage surge test43
