The standard for floor-affixed carriers and supports is ASME A112.6.1M.This Standard complements ASME A112.6.1M. Some of the specifications and tests are similar and appropr
18、iatelyreferenced in this Standard. However, due to differences in assembly of these framing-affixed products from thefloor-affixed products, some criteria are different.The basis for this Standard was an Interim Guide Criteria document prepared by the International Association ofPlumbing and Mechani

29、 fittings, for off-the-floorplumbing fixtures (i.e., water closets, urinals, bidets, lava-tories, and sinks). This Standard specifies definitions,materials, general requirements, strength and deflectionrequirements, and marking requirements. It is notintended to limit the use of other materials andd
30、esigns that comply with the requirements of thisStandard.1.2 Units of MeasurementSI units are the units of record in Canada. In thisStandard,theinch/poundunitsareshowninparentheses.The values stated in each measurement system areequivalent in application; however, each system is tobe used independen
31、tly. Combining values from the twomeasurement systems can result in nonconformancewith this Standard.
