ASTM D4566-14 pdf free download.Standard Test Methods for Electrical Performance Properties of Insulations and Jackets for Telecommunications Wire and Cable.
ASTM D4566-14 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.

Electrical tests, properly interpreted, provide information with regard to the electrical properties of the insulation. The electrical test values give an indication as to how the insulation will perform under conditions similar to those observed in the tests. Electrical tests provide data for research and development, engineering design, quality control, and acceptance or rejection under specifications.
In-process electrical tests are used primarily as process ontrol: tools in an attempt to minimize the number and magnitude of problems detected at final test of completed。
6.2 Warning—Lethal voltages Lethal voltages are a poten tial hazard during the performance of this test. It is essential that the test that the test apparatus, and all associated equipment electrically connected to it, be properly designed and installed for safe operation.
6.2.1 Solidly ground all electrically conductive parts which it is possible for a person to contact during the test.
6.2.2 Provide means for use at the completion of any test to ground any parts which were at high voltage during the test or have the potential for acquiring an induced charge during the test or retaining a charge even after disconnection of the voltage source.
6.2.3 Thoroughly instruct all operators as to the correct procedures for performing tests safely.
