AASHTO T289

Standard Method of Test for Determining pH of Soil for Use in Corrosion Testing

Applicability: AASHTO T 289 is the Standard Method of Test for Determining pH of Soil for Use in Corrosion Testing. This standard is applicable to determining the pH of both soil and water samples. The primary application of this test method is in corrosion testing, particularly to supplement soil-resistivity measurements.

Purpose: AASHTO T 289 is applied when assessing the corrosion potential of soil and water, especially in conjunction with soil resistivity measurements, to understand the likelihood of metal corrosion.
