IS 14333 : 1996(Reaffirmed 2007) Edition 1.3 (2004-12) Indian Standard HIGH DENSITY POLYETHYLENE PIPES FOR SEWERAGE — SPECIFICATION (Incorporating Amendment Nos. 1, 2 & 3) ICS 23.040 : 13.060.30 © BIS 2007 BUREAU MANAK BHAVAN , 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 OF INDIAN STANDARDS Price Group 11 Plastic Pipes and Fittings Sectional Committee, CED 50 FOREWORD This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Plastic Pipes and Fittings Sectional Committee had been approved by the Civil Engineering Division Council. Consequent to the fourth revision of IS 4984 in 1995 which covers HDPE pipes for water supply only, the technical committee felt the need to formulate a separate specification for HDPE pipes for sewerage and industrial effluents. These pipes were earlier included in IS 4984 : 1987. The committee while examining the various technical issues involved in the formulation of this standard was convinced that for the following major reasons, the HDPE pipes meant for water supply cannot be recommended for sewerage and/or for industrial effluents: a) That pipes meant for sewerage and for industrial effluents are subjected to higher temperature and chemical reactions during its life. b) That the maximum specified allowable hydrostatic design stress for water supply pipes at 30ºC for 50 years life and used in the calculation of minimum wall thickness needs modifications in view of (a) above. c) That pipes meant for water supply and for sewerage/industrial effluents need to be identified separately. In view of the reasons stated at (a) and (b) above, the committee in the absence of any established data for the level of chemical reactions and the rise in temperature above 30ºC recommended a derating factor of 0.75 over the maximum allowable hydrostatic design stress of 4.0 MPa used for PE 63 grade material for water supply. The technical committee also recommended that the HDPE pipes covered in this standard may also be used for industrial effluents provided the user shall establish suitability for the intended application based on the chemical resistivity chart given in Annex D in consultation with the manufacturer 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 on ISO/TR 10358 ‘Plastic pipes and fittings — Combined chemical resistance classification table’. The provisions relating to ovality are based on ISO/DIS 11922 (Part 1) ‘Thermoplastic pipes for the transport of fluids — Dimensions and tolerances’. Regarding guidance for laying and jointing of polyethylene pipe, including storage and handling, a reference may be made to IS 7634 (Part 2) : 1973 ‘Code of practice for plastic pipe work for potable water supplies : Part 2 Laying and jointing polyethylene (PE) pipes’. The composition of the technical committee responsible for the formulation of this standard is given 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 the text 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 rounded off in accordance with IS 2 : 1960. ‘Rules for rounding off numerical values ( revised )’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 14333 : 1996 Indian Standard HIGH DENSITY POLYETHYLENE PIPES FOR SEWERAGE — SPECIFICATION 1 SCOPE This Indian Standard lays down the requirements for high density polyethylene pipes from 63 to 1 000 mm nominal diameter of pressure rating 0.25 to 1.6 MPa in material grades of PE 63, PE 80 and PE 100, for sewerage applications. 2 REFERENCES The Indian Standards listed below are necessary adjuncts to this standard: IS No. 2530 : 1963 4905 : 1968 7328 : 1992 Title Method of test for polyethylene moulding materials and polyethylene compounds Methods for random sampling High density polyethylene materials for moulding and extrusion ( first revision ) corresponding to the maximum permissible working pressure at 30ºC, as follows: Pressure Rating Maximum Permissible of Pipe Working Pressure PN 2.5 0.25 MPa PN 4 0.40 MPa PN 6 0.60 MPa PN 8 0.80 MPa PN 10 1.00 MPa PN 12.5 1.25 MPa PN 16 1.60 MPa 3.4 Nominal Diameter (DN) The nominal diameter of pipes covered in this standard are: 63, 75, 90, 110, 125, 140, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500, 560, and 630 mm. 4 COLOUR The colour of the pipe shall be black. 5 MATERIALS 5.1 High Density Polyethylene High density polyethylene (HDPE) used for the manufacture of pipes shall conform to designation PEEWA-45-T-003 or PEEWA45-T-006 or PEEWA-50-T-003 or PEEWA-50T-006 or PEEWA-57-T-003 or PEEWA-57T-006 of IS 7328. HDPE conforming to designation PEEWA-45-T-012 or PEEWA-50T-012 or PEEWA-57-T-012 of IS 7328 may also be used with the exception that melt flow rating (MFR) shall be between 0.20 g/10 min to 1.10 g/10 min (both inclusive). 5.1.1 The specified base density between 940.0 kg/m3 and 958.4 kg/m3 (both inclusive) shall be determined at 27ºC according to procedure prescribed in Annex A of IS 7328 : 1992. The value of the density shall also not differ from the nominal value by more than 3 kg/m3 as per 5.2.1.1 of IS 7328 : 1992. 3 DESIGNATION 3.1 Pipes shall be designated according to the pressure rating ( see 3.3 ) and nominal diameter ( see 3.4 ). For example, PN 10 DN 200 indicates a pipe having a pressure rating 1.0 MPa and outside nominal diameter 200 mm. 3.2 Grade of Material 3.2.1 Pipes shall be classified according to the grade of materials given in Table 1. 3.2.2 The maximum allowable hydrostatic design stress ( r ) of a pipe is obtained by applying the design coefficient of 1.25 ( Min ) to the MRS value of the material, taking into consideration the temperature at which the pipe is to be designed for. 3.2.3 The material grading shall be given by the raw material supplier and in case of master batch, by the pipe manufacturer. 3.3 Pressure Rating Pipes shall be classified by pressure rating (PN) Table 1 Sl No. Material Grade Classification of Pipe Material Maximum Allowable Hydrostatic Design Stress ( r ), MPa                          At 20ºC (4) 5.0 6.3 8.0 At 30ºC (5) 4.0 5.0 6.3 For sewage and Industrial Efficient (6) 3.0 4.0 5.0 MRS (Minimum Required Strength) of Material in MPA, AT 20ºC, 50 Years (3) 6.3 8.0 10.0 (1) i) ii) iii) (2) PE 63 PE 80 PE 100 1 3 The resin shall be compounded with carbon black.0 280.1 6.5 19.2 Wall Thickness The minimum and maximum wall thickness of pipes for all the three grades of materials. the diameter shall be measured preferably by using a flexible P1 tape or a circometer.0 400. 7 VISUAL APPEARANCE The internal and external surfaces of the pipes shall be smooth. namely.0 160.6 4.
