This European Standard establishes requirements, test methods and evaluation of conformity for air admittance valves to be used in drainage systems installed inside buildings in accordance with EN 12056-2 and EN 12056-5. It specifies the performance requirements of air...
This standard specifies minimum requirements for compressed air line breathing apparatus with demand valve for use with a half mask at positive pressure, as a respiratory protective device. Escape and diving apparatus, apparatus for firefighting and apparatus used in abrasive blasting...
This document specifies the interface geometry between valves and pump adapters as well as flow rate performance, pressure, marking and labelling for air pumps for inflatable consumer articles (see definition in 3.1). This document does not apply to: - valves of personal...
This European Standard specifies minimum requirements for self-contained open-circuit compressed air breathing apparatus with half mask designed to include a positive pressure lung governed demand valve for escape purposes only. Such equipment is intended for use in work situations...
1.1 This International Standard is applicable to all devices intended for implantation in human hearts, as a heart valve substitute. 1.2 This International Standard is applicable to both newly developed and modified heart valve substitutes and to the accessory devices, packaging and...
Requirements for fuel gases and oxygen or compressed air safety devices used between the cylinder regulators or pipeline regulators or downstream of the pipeline valve outlet and the blowpipe (burning device) for welding, cutting and related processes. Covers non-return valve;...
Requirements for the inspection, identification and quality levels of steel castings for the pressure containing components of valves. Specifies the integrity of the pressure containing components by conformance to specific quality requirements, appropriate records and casting identification.
This European Standard provides requirements for metallic mounting kits for part-turn on-off valves and actuator attachments to enable safe and reliable operation. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up...
This European Standard specifies a method for determining valve pressure loss coefficient and fluid flow coefficient using water as test fluid. This method is suitable for valves with low zeta values but higher than 0,1 by determining pressure loss, with respect to fluid flow rate and...
