ASTM Standard will test coatings for sewer environments.
Press Release Summary:
Aug 09, 2013 - ASTM WK33537, Practice for Operating the Severe Wastewater Analysis Testing Apparatus, covers apparatus and set of procedures that are used to create and maintain simulated sewer headspace environment to be used to test potential coatings. Testing is done withÂ liquid phase containing prescribed acid and saline solution, and vapor phase consisting of air, humidity, and concentrated sewer gas. Temperature of test chamber is elevated to create accelerated conditions and reaction rates.

Proposed ASTM Metal Corrosion Standard Will Test Potential Coatings for Sewer Environments
Press release date: Jul 31, 2013
ASTM WK33537, Practice for Operating the Severe Wastewater Analysis Testing Apparatus, is being developed by Subcommittee G01.05 on Laboratory Corrosion Tests, part of ASTM International Committee G01 on Corrosion of Metals.
The apparatus described in ASTM WK33537 is designed to simulate the pertinent attributes of a typical domestic sewer wastewater headspace found in a sewer. Testing is done within two phases in the chamber: a liquid phase containing a prescribed acid and saline solution; and a vapor phase consisting of air, humidity and concentrated sewer gas, which is composed of hydrogen sulfide, carbon dioxide and methane gases.
The temperature of the test chamber is elevated to create accelerated conditions and reaction rates.
While certain chemical and physical properties of coating systems can be determined in laboratories, testing with the apparatus and procedures described in ASTM WK33537 will provide a more accurate simulation of the environment of an actual sewer system.
All interested parties are invited to participate in the standards developing activities of G01.05.
ASTM International welcomes participation in the development of its standards. For more information on becoming an ASTM member, visit www.astm.org/JOIN.
