Designation:D383914An American National StandardStandard Guide forUnderground Installation of“Fiberglass”(Glass-FiberReinforced Thermosetting-Resin)Pipe1This standard is issued under the fixed designation D3839;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice establishes procedures for the burial ofpressure and nonpressure“fiberglass”(glass-fiber-reinforcedthermosetting-resin)pipe in many typically encountered soilconditions.Included are recommendations for trenching,plac-ing pipe,joining pipe,placing and compacting backfill,andmonitoring deflection levels.Guidance for installation offiberglass pipe in subaqueous conditions is not included.1.2 Product standards for fiberglass pipe encompass a widerange of product variables.Diameters range from 1 in.to 13 ft(25 mm to 4000 mm)and pipe stiffnesses range from 9 to over72 psi(60 to 500 kPa)with internal pressure ratings up toseveral thousand pound force per square inch.This standarddoes not purport to consider all of the possible combinations ofpipe,soil types,and natural ground conditions that may occur.The recommendations in this practice may need to be modifiedor expanded to meet the needs of some installation conditions.In particular,fiberglass pipe with diameters of a few inches aregenerally so stiff that they are frequently installed in accor-dance with different guidelines.Consult with the pipe manu-facturer for guidance on which practices are applicable to theseparticular pipes.1.3 Thescopeofthispracticeexcludesproduct-performance criteria such as a minimum pipe stiffness,maxi-mum service deflection,or long-term strength.Such param-eters may be contained in product standards or designspecifications,or both,for fiberglass pipe.It is incumbent uponthe specified product manufacturer or project engineer to verifyand ensure that the pipe specified for an intended application,when installed in accordance with procedures outlined in thispractice,will provide a long-term,satisfactory performance inaccordance with criteria established for that application.NOTE1There is no similar or equivalent ISO standard.NOTE2A discussion of the importance of deflection and a presenta-tion of a simplified method to approximate field deflections are given inAWWA Manual of Practice M45 Fiberglass Pipe Design.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 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:2D8 Terminology Relating to Materials for Roads and Pave-mentsD653 Terminology Relating to Soil,Rock,and ContainedFluidsD698 Test Methods for Laboratory Compaction Character-istics of Soil Using Standard Effort(12 400 ft-lbf/ft3(600kN-m/m3)D883 Terminology Relating to PlasticsD1556 Test Method for Density and Unit Weight of Soil inPlace by Sand-Cone MethodD2167 Test Method for Density and Unit Weight of Soil inPlace by the Rubber Balloon MethodD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by MassD2487 Practice for Classification of Soils for EngineeringPurposes(Unified Soil Classification System)D2488 Practice for Description and Identification of Soils(Visual-Manual Procedure)D4253 Test Methods for Maximum Index Density and UnitWeight of Soils Using a Vibratory TableD4254 Test Methods for Minimum Index Density and UnitWeight of Soils and Calculation of Relative Density1This practice is under the jurisdiction ofASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.23 on Reinforced Plastic PipingSystems and Chemical Equipment.Current edition approved March 1,2014.Published May 2014.Originallyapproved in 1979.Last previous edition approved in 2008 as D3839 08.DOI:10.1520/D3839-14.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D4318 Test Methods for Liquid Limit,Plastic Limit,andPlasticity Index of SoilsD4564 Test Method for Density and Unit Weight of Soil inPlace by the Sleev
