9、s that are used in frame construction. At the time, a standard existedfor the evaluation of carriers for floor-affixed carriers and supports that are typically installedin commercial, industrial, and institutional buildings with concrete floors. The standard forfloor-supported carriers and supports

10、is ASME A112.6.1M.This Standard complements ASME A112.6.1M. Some of the specifications and tests aresimilar and appropriately, are referenced in this Standard. However, due to differences inassembly of these framing-affixed products from the floor-affixed products, some criteriaare different.The bas

11、is for this Standard was an Interim Guide Criteria document prepared by theInternational Association of Plumbing and Mechanical Officials (IAPMO).Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers; Attn: Secretary, A112 Main C

The waste fittings shall beassembled and all but one end capped. One end ofthe assembly shall be assembled to an air pressuredevice capable of achieving

41、 pressures from 010 psig(069 kPa gauge).34.1.2 Performance Requirements. Waste fittingsshall withstand an air pressure of 5 psig (35 kPa gauge)for one minute without leakage.4.2 Load Test (See Fig. 2)4.2.1 Test Method. The support shall be affixedto framing members in accordance with manufacturersin

42、structions. The fixture shall be assembled to thesupport. The elevation of the top edge of the fixtureat its outermost edge shall be recorded. A 500 lb (225kg) load shall be placed on the front edge of the fixturefor a period of 5 minutes. After placement of the load,the top edge shall be measured a
