Test terms vary, but results astm g31 usually be obtain within a 10 or 20 day exposure cycle. Test temperature and oxygen availability variables are also specific to the experiment. Materials Composites Metals Polymers.
NACE astm g31 method TM offers recommendations for determining optimum test times for immersion service testing.
Astm g31 is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Warning- In many cases astm g31 corrosion product on the reactive metals titanium and zirconium is a hard and tightly bonded oxide that defies removal by chemical or ordinary mechanical means. The values given in parentheses are astm g31 information only.
The solution and coupon material pair is often prescribed by the client, based on application. This practice also emphasizes the importance of recording all pertinent data and provides a checklist astm g31 reporting test data. In many such cases, astm g31 rates are established by mass gain rather than mass loss.
Surface analysis can also be aatm by stereo microscopy or scanning electron microscope to further investigate the astm g31 test morphology. Sample Requirements Samples are typically a circular specimen of about mm 1.
Immersion Corrosion Testing According to ASTM G31 Standard
These factors include specimen preparation, apparatus, test conditions, methods of cleaning specimens, evaluation of results, and calculation and reporting of corrosion rates. MES delivered high quality results in a astm g31 fashion.
I couldn’t have astm g31 happier with the service I received and the asrm MES took in making sure I was satisfied. Standard laboratory corrosion coupons are utilized to determine weight loss due to corrosion. Immersion corrosion testing is used to determine resistance of a material to anaggressive, aqueous environment.
