ASTM D2633 Standard Test Methods for Thermoplastic Insulations and Jackets for Wire and Cable
ASTM D2633固化的增强树脂燃烧损失的标准试验方法

Physical tests, properly interpreted, provide information with regard to the physical properties of the insulation or jacket. The physical test values give an approximation of how the insulation will physically perform in its service life. Physical tests provide useful data for research and development, engineering design, quality control, and acceptance or rejection under specifications.

1. Scope
1.1 These test methods cover procedures for the testing of thermoplastic insulations and jackets used on insulated wire and cable. To determine the test to be made on the particular insulation or jacket compound, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords. The electrical tests on insulation and water-absorption 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 insulation or jacket material 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 material and not to test the conductor or completed cable.
1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses 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 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards see Sections 4 and 63.
