ASTM G92-86(1997)e1

1.1 This practice gives suggested procedures for the characterization of atmospheric test sites. Continuous characteri- ization can provide corrosion data, environmental data, or both which will signal changes in corrosivity of the atmos- pheric environment. This practice can also provide guidance for classification of future test sites.

1.2 Two methods are defined in this practice for the char- acterization of atmospheric test sites. The methods are iden- tified as characterization Methods A and B. The preferred characterization technique would require using both Method A and B for concurrent data collection.

1.2.1 Method A is to be used when atmospheric corrosion is monitored on a continuing basis at a test site using specified materials and exposure configurations.

1.2.2 Method B is specified when atmospheric factors are monitored on a continuing basis.

1.3 This standard 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.
