26、lth and/or the environment if adequate precautions are not taken. It refers only to technical suitability; it does not absolve the user from their legal obligations at any stage. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to approp

27、riately qualified and experienced people. All pressures are gauge pressures unless otherwise stated. NOTE This European Standard requires measurement of material properties, dimensions and pressures. All such measurements are subject to a degree of uncertainty due to tolerances in measuring equipmen

28、t, etc. It may be beneficial to refer to the leaflet “measurement uncertainty leaflet” SP INFO 2000 27 8. BS EN 13175:2014EN 13175:2014 (E) 6 1 Scope This European Standard specifies minimum requirements for the design, testing and production testing of valves, including appropriate fittings, which

29、are connected to mobile or static LPG pressure vessels above 150 l water capacity. Pressure relief valves and their ancillary equipment, contents gauges and automotive LPG components are outside the scope of this European Standard. This European Standard does not apply to refineries or other process
