Which standard must liquid adhesive coatings used on filters not have a flash point lower than?

Liquid adhesive coatings used on filters are subject to safety regulations that address their flammability characteristics. The flash point is an important property that indicates the temperature at which a liquid can form an ignitable mixture in air.

For liquid adhesive coatings on filters, maintaining a flash point of at least 325 degrees F is crucial because this standard ensures that the materials are less likely to ignite under normal operating conditions. A higher flash point reduces the risk of fire hazards during installation, maintenance, and operation of HVAC systems where these filters are used.

Coatings with a flash point below this threshold may pose significant safety risks in environments where temperatures could approach the flash point, leading to potential fires and safety incidents. Hence, compliance with this standard is not only a matter of regulatory compliance but also a crucial aspect of ensuring safe operations within mechanical systems.
