Sets out a procedure for the measurement of electrical resistivity of fine granular materials with a maximum particle size of 2.36 mm.

This test is used for the quality control of bedding and backfilling materials for cast iron and steel pipe, buried metallic structures and reinforcement. This test does not indicate the corrosion hazards to buried metals as these are largely controlled by the nature of the groundwater.

The compacted density, moisture content and water type all influence the final value. The results obtained using this test method are specific to the conditions created within the method.
