41 Hep2O Performance DataStrength and DurabilityPull-out resistanceBS 7291: Part 2: 2001 provides a testprocedure for assessing the pull-outstrengths of pipes from pipes and fittings havebeen tested and offer resistances inexcess of these levels required by BS 7291: 2001are shown in Table pressure resistanceand life expectancyThe ability of a pipe to resist waterpressure depends upon the tensilestrength of the material, whichvaries with pipe has been tested toresist various pressures at varioustemperatures representing normaloperating life cycles. Refer to Table pipes and fittings conformto the long term hydrostaticstrength tests as detailed in BS 7291:Part 1: 2001, Clause life expectancy of not less than 50years can be extrapolated from thisdata, and is based on the range ofintermittent flow temperatures thatthese systems would normallyexperience, ranging between 12 bar20 C and 6 bar 90 exposure to temperatures upto 100 C resulting fromthermostat/system malfunction willnot cause failure, but may shortenthe long term design life of cyclingThermal cycling - the rise and fall inwa
