Scope

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

1.2 Two methods are defined in this practice for the characterization of atmospheric test sites. The methods are identified 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.

Significance and Use

This practice gives suggested procedures for characterization of atmospheric test sites. It can be useful to researchers, manufacturers, engineering firms, architects, and construction contractors to provide corrosion and environmental data, materials selection information, and a materials storage practice.

This practice does not give specific parameters for classifying the type of test site.
