Test Measurement Procedure for Determining Electrical Leakage Resistance of Pneumatic Tires on a WDK 110 Test Table

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of WDK 110 testing. This standard describes a test method for measuring the electrical resistance of pneumatic and solid tires under load in a test rig. Static loads in a vehicle sometimes need to be distributed through the tire. Electrical resistance inversely measures a tire's ability to dissipate static charge in the vehicle.

The method specifies procedures and equipment by which electrical resistance can be accurately determined for tires up to 10-12Ω. The obtained electrical resistance of the tire is the highest value of the electrical resistance measurements of all environmental measuring points.

The electrical resistance of an inflated tire mounted on a vehicle with a tire placed on a metal loading plate is measured between the vehicle frame and the conductive surface on which the tire is charged.

To minimize errors caused by contaminations, the vehicle should be placed on a metal loading plate covered with a rubber piece of damp blotter. The frame must be clean in the connection area.
