Following exposure, the samples are evaluated for corrosion resistance performance.

ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance. ASTM D describes the use of one of a number of methods to remove coating along the scribe line undercut by corrosion so that the full width of the corrosion creep width can be measured with a scale or caliper.
The arithmetic mean width of the corroded area on both sides of the scribe line is calculated for a number of satm along the scribe line, and ASTM D uses that mean width to determine a rating number from 0 to 10, with 10 representing zero 0 corrosion creep.

The less corrosion creep on either side of the scribe, dd1654 higher the corrosion resistance performance.

ASTM D – Zehntner GmbH
The purpose of the ASTM D test method is to provide a standardized procedure for the evaluation of corrosion performance of atm and metal pretreatments subjected to one of a variety of corrosion resistance exposures. ASTM D describes the scribing of coated samples through the coating layer and into the substrate using one of a number of scribe tools.
