Occasions exist where static charges on the vehicle must be dissipated by way of the tires. Electrical resistance inversely measures the tire’ability to dissipate static charge from the vehicle.

1.1 This test method describes the measurement of the electrical resistance between the wheel of a mounted and inflated tire-wheel assembly and a flat conducting surface in loaded contact with the tire.

1.2 The method specifies procedures and equipment such that electrical resistance can be accurately determined for tires with values up to 10¹² Ω (ohms).

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, 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.
