Abstract

This specification covers extruded cross linked and thermoplastic semi-conducting, conductor and insulation shielding materials for electrical wires and cables. The materials covered are not compatible with hydro carbon derivatives of a swelling or deteriorating nature. Different tests shall be performed in order to determine physical properties like brittleness, aging requirements, and elongation at rupture and volume resistivity.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
