ASTM D3004-08

1.1 This specification covers crosslinked and thermoplastic extruded semi-conducting, conductor and insulation shielding materials for electrical wires and cables.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 In many instances, the electrical properties of the shielding material are strongly dependent on processing conditions. For this reason, in this specification the material is sampled from cable. Therefore, tests are done on shielded wire in this standard solely to determine the relevant property of the shielding material and not to test the conductor or completed cable.
