Test Methods For Roof Top Supports

Traditional support methods can lead to poor management of excessive dead weight causing equipment to penetrate the roofing system.

Test methods for roof top supports.

Spray testing flood testing capacitance impedance testing nuclear metering and infrared ir thermal imaging. Staff can climb up ladders to apply de icing materials or use snow rakes or drag lines from the ground. This method works due to the ability of water to store or conduct electrical energy. 4 1 the test methods described herein are intended to provide a basis for relative comparison of roof coverings.

The test methods include simulated fire exposure to the outside of the roof coverings and where applicable a determination as to whether the fire performance characteristics of the roof coverings will be adversely affected by prolonged exposure to rain. A new astm international test method aims to prevent air leakage in and around roofs helping improve energy efficiency reduce moisture problems and prevent pollutants from entering a building. Within the last two decades two new methods of testing have revolutionized the leak detection and integrity testing industry. Get the new 2019 rooftop support systems catalog.

Keep in mind that workers and bystanders standing below could become trapped under snow falling from roofs and suffocate. Poorly designed structural supports for rooftop units can cause major roof system damage. The rooftop strut support shall provide a fixed height mounting platform with a minimum of 4 or 6 off of the roof and a usable strut length of up to 6 10 16 24 30 36 42 48 or 60. Rooftops are a common area of weakness for both priority points.

It is critical that each assembly of the building envelope be investigated for air leakage performance with appropriate standards says astm member sudhakar molleti. The procedure involves placing a hand held moisture meter on the surface of the roof which sends an electrical current into the roof without penetrating its membrane. H stands for pipe support duct support.
