1、Designation: D2633 12D2633 13 An American National StandardStandard Test Methods forThermoplastic Insulations and Jackets for Wire and Cable1This standard is issued under the fixed designation D2633; the number immediately following the designation indicates the year oforiginal adoption or, in the c
2、ase of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 These test methods cover procedures for the testing of thermoplastic insulations and jac
3、kets used on insulated wire andcable. To determine the test to be made on the particular insulation or jacket compound, refer to the product specification for thattype. These test methods do not apply to the class of products known as flexible cords. The electrical tests on insulation andwater-absor
4、ption tests do not apply to the class of products having a separator between the conductor and the insulation.1.2 These test methods pertain to insulation or jacket material for electrical wires and cables. In many instances the insulationor jacket material cannot be tested unless it has been formed
5、 around a conductor or cable. Therefore, tests are done on insulatedor jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket material andnot to test the conductor or completed cable.1.3 Whenever two sets of values are presented, in differe
6、nt units, the values in the first set are the standard, while those inparentheses are for information only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety a

Hazards4.1 High Voltage:4.1.1 WarningLethal voltages are a potential hazard during the performance of this test. It
21、is essential that the test apparatus,and all associated equipment electrically connected to it, be properly designed and installed for safe operation. Solidly ground allelectrically conductive parts which it is possible for a person to contact during the test. Provide means for use at the completion
22、of any test to ground any parts which were at high voltage during the test or have the potential for acquiring an induced chargeduring the test or retaining a charge even after disconnection of the voltage source. Thoroughly instruct all operators as to thecorrect procedures for performing tests saf
23、ely. When making high voltage tests, particularly in compressed gas or in oil, it ispossible for the energy released at breakdown to be sufficient to result in fire, explosion, or rupture of the test chamber. Designtest equipment, test chambers, and test specimens so as to minimize the possibility o
24、f such occurrences and to eliminate thepossibility of personal injury. If the potential for fire exists, have fire suppression equipment available.
