ASTM D470-13是關于《電線和電纜用交聯絕緣材料與套管的標準試驗方法》現行版本標準修訂于2013年，替代原ASTM D470-99版本使用。

1. Scope

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 The procedures appear in the following sections:

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 problems, 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 Section 4.
