Standard ASTM D1654
You need to log in before adding standards to the monitoring service. This service is not available if you are a URL user where you do not log in with an email astmm. 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.
A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. ASTM D uses corrosion creepage perpendicular to the scribe line as a quantitative measurement of corrosion performance. Assured Testing Services places parts or panels inside corrosion resistance exposure chambers, exposing them continually for specified periods of time. Start Webshop Product catalog Product presentation.
Following exposure, the samples are evaluated for corrosion resistance performance. 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 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.
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.
Webprint Printed and bound. Scraping with a spatula, picking off with a knife, chemical stripping of the coating, air blow-off, or power washing.
Monitoring V monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. The benefits of a subscription: 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.
