Roof Uplift Test

The uplift chamber is placed on a randomly selected critical area of the roof obtain an airtight seal between.

Roof uplift test.

The test evaluates the roof deck how it s attached to supports and the roof covering materials. The test increases psf in increments and records pressure at the moment the roof system experiences wind uplift failure. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof covering systems. Test the floor tiles installed on balconies check the adhesion of the roof covering proof the good installation of the waterproofing membrane.

Performance assurance step 1. The specific test that pertains to wind uplift utilizes a test apparatus designed by fm approvals. Purpose and scope. For mechanically attached single ply roofing systems the test involves building a roof assembly on a test frame that measures 12 feet by 24 feet.

Fm global fmg recommends in its property loss prevention data sheet 1 52 field veriication of roof wind uplift resistance that ield uplift testing or full time rooing construction observation be conducted for most adhered rooing sys. Fm 1 52 originally was published by fm global in october 1970. The test frame has the appropriate roof deck attached to supports. The uplift fastener tester is specially designed for the following domains.

This test is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems. The purpose of this test is to gain uplift resistance data for the panel assembly and evaluate the attachment of the roof covering systems to the roof decks. Fm loss prevention data sheet 1 52 fm 1 52 field uplift tests provides for two methods of testing. The negative pressure uplift test was added in august 1980 and has been revised several times.

Ul 580 is the standard for tests for uplift resistance of roof assemblies. Uplift resistance on completed roof systems in hurricane prone regions where a partial blow off has occurred or where inferior roof system construction is suspected or known to be present. Major roofing contractor groups such as the national roofing contractors. Tile uplift test a direct tensile load is applied by pulling up on the edge of the tile by using a tile testing scale this test verifies the tile can withstand the uplift it is designed for.

Know the parameters and use the information wisely test methods. This test determines the uplift resistance of roof assemblies consisting of the roof deck and roof covering materials by evaluating the comparative resistance of roof assemblies to positive and negative pressures. In laboratory testing wind uplift forces are applied and carefully measured in pounds per square foot psf gradually increasing the psf force until roof system failure occurs.
