ASTM G162-99

Standard Practice for Conducting and Evaluating Laboratory Corrosions Tests in Soils

SCOPE
1.1 This practice covers procedures for conducting laboratory corrosion tests in soils to evaluate the corrosive attack on engineering materials.
1.2 This practice covers specimen selection and preparation, test environments, and evaluation of test results.
1.3 This practice does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
