Technical Specifications The technical specifications, e.g. with regard to the materials and dimensions of the pipes, fittings and the entire system, are described in the standard (parts 1, 2, 3 and 5). Marking of the pipe The general requirements for the marking of pipes are described in chapter of the standard The minimum required marking of the pipe is specified in the following table: Aspects Marking or symbol Number of the standard EN ISO Manufacturer's name and/or trade mark Name or code Nominal outside diameter and nominal wall thickness e.g. 16 x 2.2 ATG letters and ATG number e.g. ATG 1245 Pipe dimensions class Material Application class combined with design pressure Opacity b e.g. A a e.g. Class 2/10 bar e.g. opaque Manufacturer's information a) For material crosslinked by: peroxide: PE-Xa silane: PE-Xb electron beam: PE-Xc azo: PE-Xd b) If declared by the manufacturer c) For proving traceability, the following details shall be given: a. the production period, year and month; in figures or in code b. a name or code for the production site if the manufacturer is producing in different sites c PCF PE-X.BCCA.TRA /10

Organisation of the inspection Sampling The inspection body, designated by BCCA, takes the pipes and fittings at random either from the stock or directly from production. Both the pipes and the fittings are subdivided into groups. The number of samples to be taken depends on this subdivision into groups: Pressure group Design pressure (bar) pd size group Nominal diameter (mm) 1 10 dn < dn 160 fitting group Nominal diameter (mm) 1 Bends 2 Tees 3 Reducers, couplers, end caps 4 Unions, flange adaptors, CEN ISO/TS PCF PE-X.BCCA.TRA /10

5 5. Tests from the admission assessment The tests relate to all of the properties that are specified in the standard and are carried out by the laboratory mentioned in annex 4 of the TRA. Initial type testing must be carried out by an accredited laboratory. This table gives the details of the tests to be carried out and the number of samples to be taken, taking into account the subdivision into groups. Type testing (in accordance with CEN ISO/TS ) Change of material Conditions - Change of polymer (M1) - Change of supplier - Change of polymerization Change chemical properties of comonomers - Change of additive package (e.g. pigments, antioxidants) (M2) - Amount greater than X ± 30% of individual additive - Change of chemical properties or nature of additive For the purposes of defining a change in design, the following properties are relevant: a) dimensions b) geometry of the component c) jointing system Entry controls ENTRY CONTROL PE self-control or control of certificate at delivery MFR Conformity of the deliveries Every batch OIT ISO with the criteria established by Every batch Moisture content NBN EN 12118; ISO 760 the manufacturer Every batch PCF PE-X.BCCA.TRA /10

PCF PE-X.BCCA.TRA /10

9 Annex A: Tensile strength of joint assemblies In order to check the resistance against the pull-out force, the following pull-out tests are provided for an assembly pipe/coupler: - pull-out test at a constant pull-out rate of 1mm/min and at 23 C; - pull-out test at a constant pull-out rate of 1mm/min and at TM + 10 C ( 90 C). The pull-out test is carried out until a failure occurs in an element of the assembly or until the pipe clearly starts leaking. The pipes may not be separated from the couplers or a minimum force Fmin must be exceeded, which is defined as follows: F min 1,5 p barst,t d 4 2 i where: Fmin minimum pull-out force (N); pfailure,t failure pressure at the appropriate temperature (MPa); di inside diameter of the pipe (mm).

10 1 Procedure A: Find the last product that corresponds to the requirements specified in Part 2 and Part 3 of the 15875, which applies. Release all products manufactured before and reject all products manufactured afterwards; Procedure B: Use a sampling procedure that is in conformity with the ISO or ISO 3951, which applies, based on a maximum AQL of 4 % and a minimum inspection level S-3. 2 If the material supplier has evaluated the hydrostatic stress properties specified in , the manufacturer of pipes only has to check the conformity with the reference curves for the expected hydrostatic strength given in Figure 1 of NBN EN ISO by testing three test pieces at two different stress levels at 95 C. The lowest stress level shall give failure times at approximately 2500 h. All failure points shall be on or above the relevant reference curve of Figure 1 of In order to check the effect of a change of additive package (M2) on the hydrostatic stress properties specified in , three test pieces must be tested at two different stress levels at 95 C. The lowest stress level shall give failure times at approximately 2500 h. All failure points shall be on or above the relevant reference curve of Figure 1 of for the appropriate material. 4 In case of doubt, the test must be carried out at 95 C-165h 5 Only if the material of the fitting is different from that of the pipe. 6 Only applicable to pipes dn 32mm PCF PE-X.BCCA.TRA /10
