im体育APP’s dynamic wind uplift testing simulates the effects of wind on membrane-roof assemblies, ensuring your product withstands wind uplift forces over time and meets the requirements of the Canadian standards CSA A123.和CAN/ ULC-S742.
风 uplift forces introduce stresses within the roof system causing fatigue, which may result in severe roof damage and premature roof failure. 测试 the resistance of roofing systems to wind dynamics has, 因此, become critical to roofing manufacturers to ensure their product resists the adverse wind conditions required by the relevant industry standards.
im体育APP has developed a wind uplift testing chamber in accordance with the standards established by the National Research Council of Canada - Institute for Research in 建设 (NRC-IRC) and is the only independent third-party laboratory in Canada to be accredited to perform dynamic wind uplift testing to both CSA A123.和CAN/ ULC-S742.
Understanding dynamic wind uplift testing
Dynamic wind uplift testing determines the dynamic uplift resistance (DUR) of a roof assembly. Knowledge of this rating is critical to select the appropriate roof assembly that can withstand potential wind uplift loads depending on the building and geographic location.
执行测试, we subject samples to dynamic wind load cycles based on wind pressure records, simulating the effects of wind on the sample in a controlled environment.
The result of a dynamic wind uplift testing provides insight to estimate the structural resistance of a roofing system and ensures it meets wind load design requirements. It also helps to identify weaknesses in the roofing system, helping manufacturers to address them before catastrophic failure occurs.
Hassle-free testing of a wide range of products and materials
im体育APP is capable of conducting dynamic wind uplift testing of MARS, 帕尔斯, 和AARS系统, evaluating a variety of materials, 包括:
- 热的障碍

为什么选择im体育APP?
im体育APP’s experts perform small and large-scale testing of both mechanically attached-membrane roofing systems (MARS), partially attached-membrane roofing systems (帕尔斯) and adhered-membrane roofing systems (AARS).
Our dynamic wind uplift chamber allows us to test to a minimum pressure of 20 kPA (400 psf) up to 10 kPA (200 psf) and is large enough to accommodate samples up to 1,880mm x 5, 791 mm (6.16 ft x 19 ft) in size. Multiple test frames enable us to test several roofs at the same time.
The apparatus can also measure air leakage rates to evaluate roofs as an 空气屏障系统. To learn more about our dynamic wind uplift testing services, or to speak to one of our experts, im体育APP 今天.
