Roof Uplift Test

The uplift fastener tester is specially designed for the following domains.

Roof uplift test.

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. 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. Performance assurance step 1. The negative pressure uplift test was added in august 1980 and has been revised several times.

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. Fm 1 52 originally was published by fm global in october 1970. Ul 580 is the standard for tests for uplift resistance of roof assemblies. Review of applicable standards and industry practice.

A 10 foot perimeter is established isolated to restrict foot traffic to ensure any movement from walking is. The test frame has the appropriate roof deck attached to supports. A pre established series. This test is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems.

The test increases psf in increments and records pressure at the moment the roof system experiences wind uplift failure. Know the parameters and use the information wisely test methods. Purpose and scope. The uplift chamber is placed on a randomly selected critical area of the roof obtain an airtight seal between.

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. 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. Major roofing contractor groups such as the national roofing contractors. 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 test evaluates the roof deck how it s attached to supports and the roof covering materials. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof covering systems. 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.
