Standard Practice for Conducting Exterior Exposure Tests of Paints and Coatings on Metal Substrates
|Publication Date:||10 December 2002|
|ICS Code (Paints and varnishes):||87.040|
This practice covers procedures to be followed for direct exposure of exterior paints and coatings to the environment when applied to metal surfaces. When originators of a weathering test have the actual exposure conducted by a separate agency, the specific conditions for the exposure of test and control specimens should be clearly defined and mutually agreed upon between all parties.
Experience indicates that the metal used as a test substrate has a significant effect upon weathering results. The purpose of this practice is to define specific steel and other metal surfaces to be used for testing in order to minimize this source of variability.
The values stated in SI units are to be regarded as the standard.
