Common corrosion state evaluations listed below:. 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.
Standard ASTM D1654
Assured Testing Services places parts or panels inside corrosion resistance exposure chambers, exposing them continually for specified periods of time.
ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
Scraping with a spatula, picking off with a knife, chemical stripping of the coating, air blow-off, or power washing. The benefits of a subscription: You need to log in before adding standards to the monitoring service.

Among the tests offered. E1654 D describes the use of one of a number of methods asgm 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 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.
Following exposure, the samples are evaluated for corrosion resistance performance. Touchstone performs corrosion testing and accelerated life testing of virtually any material aetm device.
