ASME A112.6.1

The ASME standard is the nationally recognized standard that applies to floor affixed supports for off-the-floor plumbing fixtures, including combination carriers and waste fittings for water closets, and carriers for urinals, lavatories, sinks, and water coolers. This is the reference standard used in Plumbing Codes. The Standard covers definitions, materials and finishes, general requirements, strength and deflection requirements, and details of the various types of supports. Although there are differences in design between manufacturers they all fall under the following description: a device that is anchored to the floor and concealed in the building construction (i.e. pipe chase), designed to support off-the-floor plumbing fixtures (any sanitary plumbing fixture, located adjacent to the wall, which has no visible contact with the floor in front of the wall) independent of the wall or partition. In addition, combination carriers for off-the-floor water closets include waste fittings to convey fixture discharge to the sanitary drainage system.
