Standard Method of Test for
Determining pH of Soil for Use in
AASHTO Designation: T 289~91 (2004)
1.1.This test method describes procedures and apparatus for determining a pH value for corrosion testing by use of a pH meter.
1.2.The principal use of the test is to supplement soil-resistivity measurements and thereby identify conditions under which the corrosion of metals in the soil may
be sharply accentuated. This standard is divided into two parts.
The first part involves obtaining and preparing the sample to size for testing.
The second part describes the test method for determining the pH of soil.
1.3.The values stated in SI units are to be regarded as the standard.
- M 92, Wire-Cloth Sieves for Testing Purposes
- M 231, Weighing Devices Used in the Testing of Materials
- T 2, Sampling of Aggregates
- T 248, Reducing Samples of Aggregate to Testing Size
