Corrosion & Thermal Testing

ASTM G 57/AASHTO T 288: Determining Minimum Laboratory Soil Resistivity

This test method covers the laboratory determination for the minimum resistivity of a soil. The principal use of this test method is to determine a soil's corrosivity and thereby identify the conditions under which the corrosion of metals in soil may be sharply accentuated

ASTM D 5334: Standard Test Method for Determination of Thermal Conductivity of Soil and Soft Rock by Thermal Needle Probe Procedure

This test method is used to determine the thermal conductivity (λ) of soil and soft rock using a transient heat method. This test method is applicable for both intact and reconstituted soil specimens and soft rock specimens. This test method is suitable only for homogeneous materials.

EPA Method 9040 C: pH Electrometric Measurement

This test method is used to measure the pH of aqueous wastes and those multiphase wastes where the aqueous phase constitutes at least 20% of the total volume of the waste. The corrosivity of concentrated acids and bases, or of concentrated acids and bases mixed with inert substances, cannot be measured. The pH measurement requires some water content. The pH measurement is determined electrometrically using either a glass electrode in combination with a reference potential or a combination electrode/ The measuring device is calibrated using a series of standard solutions of known pH.

ASTM G 51/AASHTO T 289: Determining pH of Soil for Use in Corrosion Testing

This test method is used to determine the pH value of soil for corrosion testing. The principal use of this test is to supplement soil-resistivity measurements and thereby identify conditions under which the corrosion of metals in the soil may be sharply accentuated.

EPA Method 9045 D: Soil and Waste pH

This test method is an electrometric procedure for measuring pH in soils and waste samples. Wastes may be solids, sludges, or non-aqueous liquids. If water is present, it must constitute less than 20% of the total volume of the sample. In this test method, the sample is mixed with reagent water, and the pH of the resulting aqueous solution is measured.
