Designation:F253606b(Reapproved 2011)Standard Guide forInstalling Plastic DWV Piping Suspended from On-GradeSlabs1This standard is issued under the fixed designation F2536;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides procedures for the installation ofDWV piping in buildings that are built where soil conditionsrequire the use of pier or piling supported grade beamconstruction or in filled ground where the soil compaction isless than 95%.These procedures are intended to ensure thatthe DWV piping suspended from the on grade concrete slabs isnot damaged or destroyed by movement of the soil or fill underthe slab after the building is completed and occupied.1.2 In this type of construction,the area within the gradebeams is filled with soil up to a level that allows the concreteslab to be poured directly on the fill without a supporting form.In this process the sanitary waste piping is installed bytrenching into the fill,and then putting hangers with supportrods on the pipes as they are installed.The hanger rodsextending upward must be long enough so that the top of therod will be embedded in and anchored in the concrete.1.3 The hanger rods are intended to provide adequatestrength and corrosion resistance to assure long term service.1.4 The details of installation are intended to ensure that therods remain vertical,that they extend into the concrete anadequate amount and that the upper ends are terminated so thatthey have adequate“pull out”strength.1.5 The details of backfill are intended to limit or minimizethe loads on the a suspended piping.These loads result fromconsolidation or movement of the soil/fill beneath the slab.1.6 The values stated in inch-pound units are to be regardedas standard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD2665 Specification for Poly(Vinyl Chloride)(PVC)PlasticDrain,Waste,and Vent Pipe and FittingsF412 Terminology Relating to Plastic Piping Systems3.Terminology3.1 GeneralDefinitions used in this guide are in accor-dance with Terminologies in F412 and D653 unless otherwiseindicated.3.2 Definitions of Terms Specific to This Standard:3.2.1 grade beamsconcrete beams around the perimeter ofa building and within the building.They support the slabs,theexterior walls and interior bearing walls.3.2.2 piers&pilingsthese are the supporting membersthat carry the grade beams and transmit the loads to adequatebearing soils and strata.3.2.3 on grade slabsthese are reinforced concrete slabspoured directly on the fill without a form under the slab.Theyare supported by the Grade Beams.NOTE1PPGB is the acronym for pier piling grade beam constructioncovered by this guide.4.Significance and Use4.1 This guide is for use by designers,specifiers,installationcontractors,regulatory agencies,owners and inspection orga-nizations who are involved in these piping installations inbuildings of this type.5.Materials5.1 The plastic piping used in these systems is listed in thePlumbing Codes as ASTM D2665.NOTE2In this guide there is reference to only D2665 pipe(schedule40 solid wall)because beam load tests reveal that the cellular core pipes1This guide is under the jurisdiction of ASTM Committee F17 on Plastic PipingSystems and is the direct responsibility of Subcommittee F17.63 on DWV.Current edition approved Feb.1,2011.Published March 2011.Originallyapproved in 2006.Last previous edition approved in 2006 as F2536 06b.DOI:10.1520/F2536-06BR11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 have much less strength than the solid wall pipe.5.2 The hangers to be used shall be the clamp-on type,shallmatch the pipe size and they shall be made of hot dippedgalvanized steel or stainless steel.The hanger shall be fastenedto the rod so that the rod is held in a vertical position.5.3 The rods shall be stainless steel and shall conform withthe sizes shown in Table 1.Rods shall extend up through the filland shall terminate with a bend or hook that will be embeddedin the slab.5.4 Hangers and rods shall be placed at four-foot centersmaximum.Each fitting shall have a hanger.6
