Testing Programme
FM Global declare to have the toughest and most challenging set of tests in the world for roofing systems. Roofing products are tested under Category 4470 for Class 1 Roof Covers and consist of the following:
1. Calorimeter Testing
This bespoke test measures the amount of energy contributed to a fire from the roofing system. The test is based on an internal fire and subjects the test sample to heat and flame from the underside of the sample, as is the case in most building fires.
2. Spread of Flame Test
This test measures the spread of flame over the roof surface and the reaction of the system to fire on different pitches as well as in differing wind conditions
3. Pull Out Testing
This set of tests is to determine the pullout resistance of the selected fasteners from a trapezoidal sheet metal decking.
4. Pull Over Testing
This set of testing is undertaken to ascertain how the combination of washer and fastener work to clamp the membrane in to position and to evaluate how much force is required to pull the membrane over the washer plate.
5. Wind Uplift Test
Once the tests 3 and 4 have been completed on the fasteners and washers, a full scale test on a roof rig is undertaken to measure the performance of all of the roof system elements to resist the forces of wind uplift.
6. Water Tightness Test of the Welded Joint
A water pressure test is undertaken on a welded joint to confirm the ability of the membrane to prevent water ingress. This test is undertaken on a sample of new membrane and a second sample of aged membrane.
7. Hailstorm Testing
This test is designed to check the systems resistance to hail and other high impact damage. Testing is undertaken on both new and aged material.
8. Step Resistance
A simple check of the system’s ability to resist foot traffic in both compression and scuff resistance.
