4.1 Pipe material

The material from which the pipe is made shall be polypropylene (PP).

Result: complied

4.2 Evaluation of LCL-values

The pipe material shall be evaluated in accordance with EN ISO 9080 or equivalent where internal pressure tests are made in accordance

with EN 921:1994 to find the sLCL-values. The sLCL-value thus determined shall at least be as high as the corresponding values of the

reference curves given in Figure 1, 2 or 3, over the complete range of times in Figure 1, 2 or 3. NOTE 1 One equivalent way of evaluation is to calculate the sLCL -value for each temperature (for example 20 °C, 60 °C and 95 °C)

individually.

NOTE 2 The reference curves in Figures 1, 2 and 3 in the temperature range of 10 °C to 95 °C are derived from the following equations:

First branch (i.e. the left hand portion of the lines as shown in Figures 1, 2 and 3)

Page 17 of 30

To demonstrate conformance to the reference lines pipe samples should be tested at following temperatures and at various hoop stresses such

that, at each of the tempeatures given, at least three failure times fall in each of the following time intervals: Tempertures 20; 60-70; 95; °C;

Time intervals 10-100 h, 100-1000 h,1000-8760 h and above 8760 h. In tests lasting more than 8760 h, once failure is reached at a stress and

time at least on or above the reference line, any time after that can be considered as the failure time. Testing should be carried out in

accordance with EN 921:1994.

Conformance with the reference lines should be demonstrated by plotting the individual experimental results on the graph. At least 97.5% of

them should lie on or above the reference line.
