(Practice)Standard Practice for Sampling of Coating Films
Standard Practice for Sampling of Coating Films
SIGNIFICANCE AND USE
Specimens for analysis must be adequately sampled, packaged, and documented to obtain meaningful information from the laboratory. The sampling procedure and packaging will be dependent upon the reason for taking the sample.
SCOPE
1.1 This practice covers methods to remove samples of coating films for subsequent analysis related to identification of generic coating type and failure analysis or other reasons. These techniques can be used in the field, the fabricating shop, or laboratory.
1.2 The method for obtaining coating samples for heavy metal analysis is presented in Practice D 5702.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
