T/CGMA 022001-2019 Roof ventilation device rainproof performance test method
Abstract
This standard specifies the rules for the simulation device and test arrangement, instruments and meters, test methods, evaluation of test results, and test reports for the rainproof performance of roof ventilation devices.
This standard is applicable to the determination of the rainproof performance of the main structures of various types of ventilation devices installed vertically on roofs for air supply and exhaust under standardized laboratory conditions. These roof ventilation devices (hereinafter referred to as roof fans) include both roof ventilation fans with drive devices as defined in GB/T 19075, as well as non-powered roof fans and roof ventilators, etc. - natural ventilation devices on roofs.
This standard is not applicable to the rainproof performance of fan installation bases and their installation methods.
