적용범위

1.1?These test methods cover procedures for testing crosslinked insulations and jackets for wire and cable. To determine the test to be made on the particular insulation or jacket, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords.

1.2?In many instances the insulation or jacket cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket and not to test the conductor or completed cable.

1.3?These test methods appear in the following sections:

Test Method	Section(s)
?	?
AC and DC Voltage Withstand Tests	22 to 29
Capacitance and Dissipation Factor Tests	38 to 44
Cold Bend	124
Cold Bend, Long-time Voltage Test on Short Specimens	51 to 57
Double AC Voltage Test on Short Specimens	45 to 50
Electrical Tests of Insulation	17 to 64
Heat Distortion Test	123
Horizontal Flame Test	100 (Test Method D7936)
Insulation Resistance Tests on Completed Cable	30 to 37
Mineral Filler Content, Determination of	107 to 111
Ozone Resistance Test	87 to 99
Partial-Discharge Test	58 to 64
Physical Tests of Insulation and Jacket Compounds	?5 to 16
Surface Resistivity Test	112 to 116
Track Resistance Test	125 to 128
U-Bend Discharge Test	117 to 121
Water Absorption Test	65 to 71
Water Absorption Test, Accelerated	72 to 86
Water Absorption Test on Fibrous Coverings	?101 to 106

1.4?Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in the parentheses are for information only.

1.5?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazards see Section 4.

1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
