Conducting and dissipative rubbers, vulcanized or thermoplastic — Measurement of resistivity

This document specifies the requirements for the laboratory testing of the volume resistivity of specially prepared test pieces of vulcanized or thermoplastic rubber compounds rendered conducting or dissipative by the inclusion of carbon black or ionizable materials. The tests are suitable for materials with a resistivity of less than about 108 Ω⋅m.

Method 1 is the preferred method when test pieces with bonded electrodes are not available.

Method 2 is the preferred method when test pieces are moulded with the inclusion of bonded electrodes.

Method 3 is another method that can be used if the apparatus for method 1 or 2 is not available, but it has lower accuracy.

If a reference to this document is made without specifying the method, method 1 is used.
