16 European Technical Approval ETA-07/0275 Page 16 of 23 ANNEX A Demonstrating conformance to the reference curves A.1 Principle The material from which the stress bearing layer of the pipe or the fitting is made, is evaluated with the standard reference curves. For this internal pressure tests on pipes which are extruded from the material are made in accordance with EN 921. Conformance to the reference curves per temperature shall be demonstrated by establishing individual failure points on a graph line by using the least square method and a matching 97,5% lower confidence limit (LCL). The 97,5% lower confidence data points are compared with values from the reference curves at the same temperature. A.2 Apparatus The equipment shall be in accordance with EN 921. A.3 Sample Preparation The preparation of the test pieces shall be in accordance with EN 921, with end caps type A. The number of test pieces take into account the provision given in clause A.5.2 of this annex. A.4 Reference Curves A.4.1 Reference curves for the PE-RT Type II pipes The reference curves of the PE-RT material for the pipe are depicted in figure A1 The reference curves in figure A1 in the temperature range of 10 C to 110 C are described by the following equation: A , ,93 logσ log t = 172, ,153 log σ T T Reference curves for the fitting material The reference curves of the fitting material shall be provided by the manufacturer. The curves shall be based on injection moulded pipe segments of the fitting material. The manufacturing of the injection moulded pipe segments shall be conform EN A.5 Procedure A.5.1 A.5.2 A.5.3 A.5.4 Manufacturing of the test pieces shall be in accordance with clause 3 of this annex. Tests shall be performed in accordance with EN 921 in water or air, at various hoop stresses such that at each of the temperatures given at least three failure times fall in each of the following time intervals: Temperatures : 20 C, 60 C to 80 C and 95 C Time intervals : 10h to 100h : 100h to 1000h : 1000h to 8760h : >8760h If tests lasting more than 8760 hours, once failure is reached at a stress and time on or above the reference line, any time after that may be considered as the failure time. The failure data points determined in clause A.5.2 shall be plotted in a graph per temperature. By using the least square method a line is constructed over the testing period of time. From this plotted line the 97,5% lower confidence limit data points for the lowest and highest failure times shall be determined. These 97,5% LCL data points at a chosen temperature are compared with the data points from the reference curves at the same temperature.
