The purpose of the ASTM D test method is to provide a standardized procedure for the evaluation of corrosion performance of d and metal pretreatments subjected to one of a variety of corrosion resistance exposures.

The arithmetic mean width of the corroded area on both sides of the scribe line is calculated for a number of locations 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.

ASTM D describes the scribing of coated samples through the coating layer and into the substrate using one of a number of scribe tools. This ensures that you are always up-to-date and saves you both time and money.
Following exposure, the samples are evaluated for corrosion resistance performance.

d16654 ASTM D describes the use of one of a number of methods to remove coating aztm the scribe line undercut by corrosion so that the full width of the corrosion creep width can be measured with a scale or caliper. ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance.
Scraping with a spatula, picking off with a knife, chemical stripping of the coating, air blow-off, or power washing.
Touchstone performs corrosion testing and accelerated life testing of virtually any material or device. The less corrosion creep on either side of the scribe, the higher the corrosion resistance performance. Webprint Printed and bound.
