HIGH DENSITY POLYETHYLENE PIPES FOR SEWERAGE — SPECIFICATION

(Incorporating Amendment Nos. 1, 2 & 3)

ICS 23.040 : 13.060.30

Plastic Pipes and Fittings Sectional Committee, CED 50

FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized bythe Plastic Pipes and Fittings Sectional Committee had been approved by the Civil EngineeringDivision Council.

Consequent to the fourth revision of IS 4984 in 1995 which covers HDPE pipes for water supplyonly, the technical committee felt the need to formulate a separate specification for HDPE pipesfor sewerage and industrial effluents. These pipes were earlier included in IS 4984 : 1987. Thecommittee while examining the various technical issues involved in the formulation of thisstandard was convinced that for the following major reasons, the HDPE pipes meant for watersupply cannot be recommended for sewerage and/or for industrial effluents:

a) That pipes meant for sewerage and for industrial effluents are subjected to highertemperature and chemical reactions during its life.

b) That the maximum specified allowable hydrostatic design stress for water supply pipes at30ºC for 50 years life and used in the calculation of minimum wall thickness needs modifica-tions in view of (a) above.

c) That pipes meant for water supply and for sewerage/industrial effluents need to be identifiedseparately.

In view of the reasons stated at (a) and (b) above, the committee in the absence of any establisheddata for the level of chemical reactions and the rise in temperature above 30ºC recommended aderating factor of 0.75 over the maximum allowable hydrostatic design stress of 4.0 MPa used forPE 63 grade material for water supply.

The technical committee also recommended that the HDPE pipes covered in this standard mayalso be used for industrial effluents provided the user shall establish suitability for the intendedapplication based on the chemical resistivity chart given in Annex D in consultation with themanufacturer of the pipes.

In the formulation of the standard a great deal of assistance has been derived from ISO/DIS 4427.‘Polyethylene pipes for water supply—Specification’. Annex D of this standard is based mainly onISO/TR 10358 ‘Plastic pipes and fittings — Combined chemical resistance classification table’. Theprovisions relating to ovality are based on ISO/DIS 11922 (Part 1) ‘Thermoplastic pipes for thetransport of fluids — Dimensions and tolerances’.

Regarding guidance for laying and jointing of polyethylene pipe, including storage and handling, areference may be made to IS 7634 (Part 2) : 1973 ‘Code of practice for plastic pipe work for potablewater supplies : Part 2 Laying and jointing polyethylene (PE) pipes’.

The composition of the technical committee responsible for the formulation of this standard isgiven in Annex E.

This edition 1.3 incorporates Amendment No. 1 (October 2000), Amendment No. 2(September 2003) and Amendment No. 3 (December 2004). Side bar indicates modification of thetext as the result of incorporation of the amendments.

For the purpose of deciding whether a particular requirement of this standard is complied with,the final value, observed or calculated, expressing the result of a test or analysis, shall be roundedoff in accordance with IS 2 : 1960. ‘Rules for rounding off numerical values ( revised )’. The numberof significant places retained in the rounded off value should be the same as that of the specifiedvalue in this standard.

9 SAMPLING, FREQUENCY OF TESTS AND CRITERIA FOR CONFORMITY9.1 Type Tests9.1.1 Type tests are intended to prove thesuitability and performance of a new composi-tion, a new technique or a new size of a pipe. Suchtests, therefore, need be applied only when achange is made in polymer composition ormethod of manufacture, or when a new size ofpipe is to be introduced. Even if no change isenvisaged, type test shall be done at least once intwo years on each pressure rating of pipe of thehighest size manufactured during the period.9.1.2 Three samples of the same size and samepressure rating selected at random shall betested for compliance with the requirements ofthe type test, given in Table 6.9.1.3 If all the samples pass the requirementsof the type test, the type of the pipe underconsideration shall be considered eligible fortype approval.9.1.4 In case any of the samples fails in the typetest, the testing authority, at its discretion, maycall for fresh samples not exceeding the originalnumber and subject them to the type test again.If in repeat test, no single failure occurs, the typeof pipe under consideration shall be consideredeligible for type approval.

CHEMICAL RESISTANCE CLASSIFICATION TABLE FOR HDPE PIPES AND FITTINGS

D-1 GENERALD-1.1 This Technical Report is a referencedocument and provides guidelines on classifica-tion of the chemical resistance of High densityPolyethylene (HDPE) pipe material to specifiedfluids over a range of temperatures (20ºC and60ºC). It is intended to provide information on

suitability of HDPE piping for the conveyanceof fluids.D.1.2 The preliminary chemical-resistanceclassification given in the annexed table is onlysuitable for use with pipes which are not subjec-ted to internal and external mechanical stresses(for example, those caused by internal pressure,

p = test pressure in MPa;s = minimum wall thickness in mm;

σ1 = induced stress in MPa; andd = outside diameter of pipe, in mm.

flexural stresses). In order to assess thebehaviour of pipes and fittings for conveyance offluids under pressure or in the presence of otherstresses, if the preliminary classification is S orL, it will be necessary to carry out further testsas specified in ISO 8584-1 and or ISO/TR 8584-2.D-1.3 To assess the tendency of a materialtowards environmental stress cracking, separatetests have to be carried out. Other properties ofthe pipe material (for example permeability) or ofthe fluid conveyed (for example toxicity,inflammability, etc,) should also be consideredseparately.D-1.4 The table summarizes the data given in anumber of chemical resistance tables at presentin use in various countries, derived from bothpractical experience and test results. Thisevaluation is based on values obtained byimmersion of high density polyethylene testspecimens in the fluid concerned at 20ºC or60ºC and atmospheric pressure, followed incertain cases by the determination of tensilecharacteristics.D-1.5 In the preparation of this appendix,assistance has been derived from the following:

D-2 EXPLANATION OF SYMBOLS AND ABBREVIATIONSD-2.1 Classification (Last Column in the Table)The following symbols are used to indicate thebehaviour of HDPE pipes in contact withchemical agents:

The pipes can be used for applications in whichthey are not subjected to pressure or otherstresses; for applications in which they areexposed to pressure, the final assessment shallbe on the basis of subsequent test underpressure.

HDPE pipes can be used for applications inwhich they are not subjected to pressure orother stress, but a case in which a certainamount of corrosion can be accepted. Forapplications in which they are exposed topressure, the final assessment shall be on thebasis of a subsequent test under pressure.

The pipes are seriously attacked. They shall notbe used for either pressure or non-pressureapplications. There is no point in conducting.tests under pressure as the pipes would becertain to fail these tests.
