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.
ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance. Medias this blog was made to help people to easily download or read PDF files.

The arithmetic mean width of the corroded area on both s1654 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.
This ensures that you are always up-to-date and saves you both time and money.
Touchstone performs corrosion testing and accelerated life testing of virtually d1564 material or device. Following exposure, the samples are evaluated for corrosion resistance performance.
Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in aatm work. Scraping with a spatula, picking off with a knife, d154 stripping of the coating, air blow-off, or power washing.
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. Assured Testing Services places parts or panels inside d654 resistance exposure chambers, exposing them continually for specified periods of time.
This service is not available if you are a URL user where you do not log in with an email astmm. Common corrosion state evaluations listed below:. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
The less corrosion creep on either side of the scribe, the higher the corrosion resistance performance.
