Test procedures and acceptance criteria A.1 General requirements A.1.1 Purpose These general requirements shall be applied to all the test procedures detailed in this annex. Safety aspects of valve testing are not covered in this European Standard. NOTE Users of this European Standard should analyse the hazard resulting from the pressure and take proper safety precautions. A.1.2 Test equipment The test equipment shall be of such a design that it does not subject the valve to externally applied loads which may affect the results of the test. NOTE The test equipment can apply external loads sufficient to react to the forces resulting from the test pressure. When using test equipment and procedures different to that detailed in this European Standard, the manufacturer shall be able to demonstrate the equivalence of such test procedures and acceptance criteria with the requirements of this European Standard. A.1.3 Measuring equipment The measuring equipment shall be capable of measuring fluid pressure with an accuracy of ± 5 % of the required test pressure. A.1.4 Painted, coated or lined valves Before the shell strength test, reference P10, and the shell tightness test, reference P11, valves shall not be painted externally or otherwise coated with materials capable of sealing against leakage from external surfaces of the shell. Valves with liners, internal linings or coatings forming a design feature of the valve may be tested with the liner, after lining or coating. Attention shall be given that the liners, internal linings or coatings are not damaged by the test procedure. NOTE If tests in the presence of a representative of the purchaser are specified, painted or coated valves from stock may be retested without removal of painting or coating. A.1.5 Test fluid The test fluid to be used shall be:  either a liquid (water which may contain a corrosion inhibitor, or any other suitable liquid having a viscosity not greater than water);  a gas (air or other suitable gas).
