A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Keywords section was editorially updated in July This specification covers requirements and methods oftest for materials, dimensions and tolerances, hydrostatic-burststrength, chemical resistance, and longitudinal tensile proper-ties, for Reinforced Epoxy Resin pipe and fittings for use in gasmains and services for direct burial and insertion pipe and fittings covered by this specification are intendedfor use in the distribution of natural gas, petroleum fuels(propane air and propane butane vapor mixtures), manufac-tured and mixed gases where resistance to gas permeation,toughness, resistance to corrosion, aging, and deteriorationfrom water, gas, and gas additives are required.

Abbreviations are in accordance withTerminology D 1600, unless otherwise indicated. The abbre-viation for fiberglass pipe is RTRP and the abbreviation forfiberglass fittings is The gas industry technology used in this specificationis in accordance with definitions given in The Department ofTransportation of Natural and Other Gas by Pipeline MinimumSafety Reinforced Thermosetting Resin Pipe Ma-terials Designation Code The pipe material designation codeshall consist of the abbreviation RTRP followed by type andgrade in arabic numerals, class by a capital letter and the longterm steady pressure strength by a second capital letter.

5 Thefittings material designation shall consist of the abbreviationRTRF followed by type (method of manufacture), grade(general type of Resin ), class (configuration of joining system),and pressure The pipe covered in this specification is made bythe filament winding process and is described in SpecificationD 2996. Requirements of this pipe are based on short-term testsdefined in this This specification covers Reinforced epoxyresin fittings described in specification D 5685 and made of thetype of materials covered in Section 5, which are capable ofbeing joined to the pipe and will provide a suitable gasdistribution The resins and reinforcements used to make pipe shallbe as specified in This specification covers glass fiber Reinforced epoxyresin pipe and fittings as defined in Specification D 2996 RTRP 11 AU and RTRP 11 CU and fittings as defined inspecification D 5685-RTRF 11A1D, RTRF 21A1D, RTRF11F2D and RTRF The particular Reinforced thermosetting Resin included ini-tially in this specification for gas pressure piping was selected on the basisof engineering test studies made by Battelle Memorial Institute, experi-mental use in field installations.

6 And technical data supplied by themanufacturers of the plastics materials used to make the pipe and is the intent of ASTM Committee D-20 on Plastics to consider forinclusion other resins and reinforcements in this specification whenevidence is presented to show that they are suitable for gas requirements are an ASTM pipe specification and long-termstrength determined in accordance with Test Method D 2992, ProcedureB, in addition to the requirements of this The pipe and fittings shall be free ofvisible cracks, holes, foreign inclusions, blisters, and otherinjurious defects. The pipe and fittings shall be as uniform ascommercially practicable in color, opacity, density, and otherphysical Dimensions and The outside diameter of the pipe shall bein accordance with Table 1 when measured in accordance Thickness The wall thickness of the pipe shallmeet the requirements given in Table 1 when measured inaccordance with The pipe shall be in lengths as specified onthe purchase order when measured in accordance with Either threaded adaptors or bonded joints are of up to 5 % of the shipment are acceptable to meet the lengthrequirements.

The number of fittings required varies, de-pending upon the size and type of fitting. It is suggested that asampling plan be agreed upon by the purchaser and themanufacturer (see Practice D 1898). Unless otherwise specified, conditionthe specimens prior to test at 2362 C ( F) and 5065 % relative humidity for not less than 48 h, in accordancewith Procedure A of Practice D 618 for those tests whereconditioning is required and in all cases of Conditions Conduct the tests in the StandardLaboratory Atmosphere of 2362 C ( F), unlessotherwise and Thickness and Diameter Determine in accor-dance with Practice D Thickness When the test specimens contain aliner, determine the average liner thickness in accordance withPractice D Hydrostatic Failure Strength (MinimumHoop Stress) Determine in accordance with Test MethodD 1599.
