ASME A112.6.3 Standard Guide - Floor Drain Requirements
Understanding ASME A112.6.3 standard for floor drains.
ASME A112.6.3 is the American National Standard covering the design and performance requirements for floor, area, adjustable floor, and trench drains used inside buildings.
The standard specifies requirements for material specifications (stainless steel, cast iron, PVC), flow rate performance testing, load class ratings, dimensional requirements, and installation guidelines.
ASME A112.3.1 specifically covers stainless steel drainage systems including linear/channel drains with requirements for installation and performance.
For US and Canadian markets, many jurisdictions require third-party listing through cUPC (IAPMO) or CSA for drains used with plumbing systems.
Commercial kitchen drains may also require NSF/ANSI certification for use in food service environments.
