|ICS Code (Flanges, couplings and joints):||23.040.60|
This Standard specifies a method for checking the leaktightness under internal pressure of assembled joints (excluding fusion-welded joints) between fittings and polyolefin pressure pipes while subjected to bending. It details a calculation method for the average bending radius and the procedure for achieving this bending. Checking of the leaktightness under internal pressure is carried out in accordance with the method given in EN 715. The test method is applicable regardless of the design and material of the fitting used for jointing pipes.
