    Significance and Use

    This test method provides a means of evaluating and comparing development of corrosion at scribe on painted/coated flat test panels after exposure to corrosive environments.

    1. Scope

    1.1 This test method covers the measurement of rust creepage area from a scribe line on painted/coated flat test panels after exposure to corrosive environments. This test method has the advantage of simplicity and ease of use. Expensive equipment is not required, and the results are more accurate than visual evaluation but not as precise as advanced digital imaging.

    1.2 This test method uses visual imaging software to determine the area damaged by rust creepage from the scribe.

    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.
