UL 580 / UL 1897

Uplift Resistance UL 1897 – Structural Performance
Underwriters Laboratories (UL) 580 tests for Uplift Resistance of Roof Assemblies.  The UL 580 test method determines the uplift resistance of roof assemblies consisting of the roof deck and roof covering materials.

UL 1897  is the test method used to provide uplift resistance data for the evaluation of the attachment of roof covering systems to roof decks by using differential air pressures.  The UL 1897 test evaluates the roof covering systems method of attachment including all roofing components such as.
