Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom BS EN 12201-3:2011+A1:2012 EN 12201-3:2011+A1:2012 (E) Introduction The System Standard, of which this is Part 3, specifies the requirements for a piping system and its components when made from polyethylene (PE), intended to be used for water supply intended for human consumption, including the conveyance of raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by EN 12201 (all parts): a) this European Standard provides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) products intended for use in water supply systems must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC) If relevant, when the ouputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Mandate M136 which will contain formal references to the applicable requirements Until such amendments, the current national regulations remain applicable Requirements and test methods for material and components, other than fittings, are specified in EN 12201-1, EN 12201-2 and prEN 12201-4:2011 Characteristics for fitness of purpose are covered in EN 12201-5 CEN/TS 12201-7 [2] gives guidance for the assessment of conformity This Part of EN 12201 covers the characteristics of fittings BS EN 12201-3:2011+A1:2012 EN 12201-3:2011+A1:2012 (E) Scope This !European Standard" specifies the characteristics of fittings made from polyethylene (PE 100 and PE 80) intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes NOTE For PE components intended for the conveyance of water for human consumption and raw water prior to treatment, attention is drawn to 5.6 of this part of EN 12201 Components manufactured for water for other purposes, drainage and sewerage may not be suitable for water supply for human consumption It also specifies the test parameters for the test methods referred to in this standard In conjunction with Parts 1, ,4 and of EN 12201, it is applicable to PE fittings, their joints and to joints with components of PE and other materials intended to be used under the following conditions: a) allowable operating pressure, PFA, up to 25 bar 1); b) an operating temperature of 20 °C as a reference temperature; c) buried in the ground; d) sea outfalls; e) laid in water; f) above ground, including pipes suspended below bridges NOTE For applications operating at constant temperature greater than 20 °C and up to 40 °C, see Annex A of EN 12201-1:2011 EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes These fittings can be of the following types: a) b) c) 1) fusion fittings; 1) electrofusion fittings; 2) spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion); 3) socket fusion fittings (see Annex A); mechanical fittings; 1) compression fittings; 2) flanged fittings; fabricated fittings (see Annex

pipes having reduced free length sufficient to suppress pipe failure and create preferential failure in the fitting or in the connecting pipeto-fitting joint, is placed in a controlled-temperature environment and subjected to an essentially continually increasing internal hydraulic pressure until failure occurs The method is designed to establish the short-term failure pressure of the fitting/pipe assembly D.2 Apparatus D.2.1 Constant-temperature water bath, in accordance with EN ISO 1167-1, capable of being maintained at (20 ± 2) °C D.2.2 Pressure test equipment, in accordance with EN ISO 1167-1, capable of applying a continuously increasing internal hydraulic pressure at a rate of (5 ± 1) bar/min 2) until the test piece fails D.2.3 Pressure gauge, having an accuracy of not less than % of full-scale deflection and with a hand which indicates the maximum pressure reached A gauge shall be used that will indicate the failure pressure at approximately mid-scale The gauge should preferably be equipped with a surge protection device The gauge shall be located in a position within the pressure system such that it will indicate the internal pressure of the test piece without being affected by pressure transients within the pressure supply lines, etc D.3 Test piece The test piece shall be an assembly of one or more electrofusion fittings connected to PE pipes, with a minimum free pipe length between fittings of any type not exceeding dn The pipes used shall be the thickest-walled pipe for which the fitting has been designed The test piece shall be closed with type A end caps in accordance with EN ISO 1167-1 D.4 Procedure Attach the end caps to the test piece and fill it with water at ambient temperature Connect the test piece to the pressure source, ensuring that no air is trapped in the test assembly 2) bar = 0,1 MPa = 105 Pa; MPa = N/mm2 37 BS EN 12201-3:2011+A1:2012 EN 12201-3:2011+A1:2012 (E) Immerse the test piece in the constant-temperature bath and condition it at (20 ± 2) °C for at least as long as the period defined in EN ISO 1167-1 for the appropriate pipe wall thickness Increase the pressure uniformly at a rate of (5 ± 1) bar/min until failure of the test piece occurs Record the pressure at failure After testing, inspect the test piece and record the location and mode of failure D.5 Test report The test report shall include

12201-3:2011+A1:2012 EN 12201-3:2011+A1:2012 (E) Annex E (normative) Tensile test for fitting/pipe assemblies E.1 Principle A test piece consisting of an electrofusion fitting and two connecting PE pipes is subjected to an increasing tensile load at a constant pulling rate until ductile pipe failure occurs The test is conducted at a constant temperature and is intended to simulate the creation of longitudinal tensile loading along a pipeline because of external mechanical interference Rupture of the fitting or the connecting fusion joints is not an acceptable failure mode E.2 Apparatus This shall be in accordance with ISO 13951, with the additional requirement that the tensile-testing machine shall be capable of accommodating a test piece elongation of 25 % and of sustaining a constant test speed of (5 ± 1,25) mm/min E.3 Test piece The test piece shall be in accordance with ISO 13951 In cases where dn ≥ 180 mm and where the conduct of tensile tests on fitting/pipe assemblies is beyond the limits of the available test equipment, the testing of joint segments may be appropriate Testing of segment test pieces shall not be undertaken, however, unless a correlation with testing of complete pipe/joint assemblies has been established E.4 Procedure This shall be in accordance with ISO 13951, but without that International Standard’s requirement for the load to be constant The pulling rate shall be mm/min ± 25 %, sustained until a test piece elongation of 25 % is reached E.5 Test report The test report shall include the following information: a) reference to EN 12201-3; b) all details necessary for complete identification of the pipes and electrofusion fittings used, including manufacturer, type of material and size of fitting and pipe; c) details of the fusion-jointing procedure used to assemble the test piece; d) test temperature; 39 BS EN 12201-3:2011+A1:2012 EN 12201-3:2011+A1:2012 (E) e) leaktightness and integrity of the fitting and fusion joint after 25 %
