scope:

This document describes a test method to measure the electrical resistance of pneumatic and solid tyres, under load, on a test rig. Static charges on a vehicle sometimes need to be dissipated by way of the tyre. Electrical resistance inversely measures the ability of the tyre to dissipate static charge from the vehicle.

The method specifies procedures and equipment such that electrical resistance can be accurately determined for tyres with values up to 10¹² Ω.

Annex A specifies the limit values in ohms (Ω) for both dissipative and conductive tyres. Annex B specifies additional conditions for measurement on a vehicle. Annex C specifies simplified test conditions for production control routine
