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.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
ASTM D describes the scribing of coated samples through the coating layer and into the substrate using one of a number of scribe tools. The benefits of a subscription: D165 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.

This service is not available if you are a URL user where you do not log in with an email astmm. You need to log in before adding standards to the monitoring service. Medias this blog was made to help people to easily download or read PDF files. ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance.
Following exposure, the samples are evaluated for corrosion resistance performance. If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password.
Assured Testing Services places parts or panels inside corrosion resistance exposure chambers, exposing them continually for specified periods of time. 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 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 asmt caliper. The less corrosion creep on either side of the scribe, the higher the corrosion resistance performance. Touchstone performs corrosion testing and accelerated life testing atsm virtually any material or device.
