Our Roof Drains were tested in IAPMO R&T labs in US to determine the flow rate (drain capacity) of each product. The results help in designing the roof drainage system.
Now, MEP engineers can use the testing results as the maximum flow rate that our drain could provide.
Scope of Testing: To determine the flow rates through roof drains based on the head height of water at the roof drain, per section 7.2 "Recommended test protocol to be added to ASME A112.6.4" of "Storm Drainage System Research Project-Flow
rate Through Roof Drains" by ASPE.
