On the surface, polyethylene storage tanks can look pretty similar. It isn’t easy to tell a well-designed and constructed tank from a cheap, inferior tank. Many customers don’t realize that there’s a standard for tank construction based on resin properties and testing. Others simply assume all tank manufacturers follow the ASTM D 1998 standards.
ASTM standards require that all polyethylene tanks and tank materials go through three tests to determine the strength and structural integrity of the chemical storage tank. There is also an additional test for cross-linked polyethylene tanks to measure the chemical makeup of the tank materials. Together, these standardized tests help ensure that you have the strongest, most durable chemical storage tank available.
