Phạm vi áp dụng / Scope of standard

This test method describes procedures and apparatus for determining a pH value for corrosion testing by use of a pH meter.

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.

The values stated in SI units are to be regarded as the standard.
