Corrosion testing on HVAC coatings can be conducted according to a number of standards, including ASTM-B117, ISO 9227, ISO 12944-6, and ISO 20340. Of these tests, the one we believe represents actual service environments most closely is ISO 12944-9 (formerly ISO 20340) vs. the more common ASTM B-117. ISO classifies
To further expand on Heresite’s expansive chemical resistance guide, P-413 coated steel, copper, and aluminum panels were placed in a municipal wastewater treatment facility to simulate sewage fumes. Panels were placed at the point where raw sewage is pumped into the facility and screened; this results in significant hydrogen sulfide
ASTM B-117 was the first nationally recognized salt spray standard. Published in 1939, this salt spray test is widespread and often recognized as the “gold standard” in corrosion testing. However, ISO 20340 offers a more realistic and updated method of testing, representing a significant improvement over ASTM B-117. When the
HVAC-R coating chemical resistance is often tested using fume exposure. While this method of testing can provide information on the anticipated level of protection for HVAC-R equipment, in certain applications, spot/direct exposure tests may provide better information about your equipment’s longevity in real-world conditions. It is important to conduct spot/direct
For over 80 years, Heresite coatings have been used to protect HVAC-R equipment in the harshest environments. We’re proud of our history, and we’re proud to continue to offer products like P-413, which recently met the demanding offshore marine requirements of ISO 20340. These are tested, proven, real-world results. Unfortunately,
Offshore paint qualification standard approximates real-world environmental conditions Manitowoc, Wis. (June 23, 2017) – Heresite, a leader in the development of thin film corrosion resistant coatings, has successfully met the demanding requirements of ISO 20340 – regarded as a key corrosion standard for performance coating systems destined for offshore structures,
There are several tests that can be used to measure the effectiveness of protective coatings for HVAC/R coils. These testing processes have evolved over the years as various organizations have tried to provide the most accurate information to engineers, manufacturers, and businesses that need to protect their HVAC/R investment.
