Roof Uplift Test

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.

Roof uplift test.

Review of applicable standards and industry practice. The negative pressure uplift test was added in august 1980 and has been revised several times. Fm loss prevention data sheet 1 52 fm 1 52 field uplift tests provides for two methods of testing. The test frame has the appropriate roof deck attached to supports.

Test variables and concerns. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof covering systems. Performance assurance step 1. 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.

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. The test evaluates the roof deck how it s attached to supports and the roof covering materials. Test the floor tiles installed on balconies check the adhesion of the roof covering proof the good installation of the waterproofing membrane. Major roofing contractor groups such as the national roofing contractors.

The specific test that pertains to wind uplift utilizes a test apparatus designed by fm approvals. Fm 1 52 originally was published by fm global in october 1970. 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. The uplift chamber is placed on a randomly selected critical area of the roof obtain an airtight seal between.

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. Ul 580 is the standard for tests for uplift resistance of roof assemblies. The uplift fastener tester is specially designed for the following domains. 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.

Purpose and scope. A 10 foot perimeter is established isolated to restrict foot traffic to ensure any movement from walking is. Know the parameters and use the information wisely test methods. This test is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems.
