This standard applies to outlet connections of gas cylinder valves for gases and gas mixtures and concerns special requirements where the highest levels of cleanliness and freedom from particles are demanded for the manufacture of microelectronic components or similar...
This standard specifies a test sequence and acceptability criteria for connections between gas cylinders and valves for gases and gas mixtures used under special conditions of service where the highest levels of cleanliness and/or freedom from particles are demanded for...
This International Standard establishes requirements and provides guidelines for configuration, installation, test, operation and documentation of subsurface safety valve (SSSV) systems. In addition, this International Standard establishes requirements and provides guidelines for selection,...
ISO 22434:2006 specifies the requirements for the inspection and maintenance of cylinder valves, including valves with integrated pressure regulators (VIPR) (see ISO 22435). ISO 22434:2006 may be applied to cylinder valves at the time of the periodic inspection of gas...
This part of ISO 11114 specifies a test method to determine the autogenous ignition temperature of non-metallic materials in pressurized gaseous oxygen. The autogenous ignition temperature is one criterion for ranking materials, and can be used to assist with the choice of materials used in the...
ISO 11114-3:2010 specifies a test method to determine the autogenous ignition temperature of non-metallic materials in pressurized gaseous oxygen. The autogenous ignition temperature is one criterion for ranking materials, and can be used to assist with the choice of materials used in the presence...
ISO 10432:2004 provides the minimum acceptable requirements for subsurface safety valves (SSSVs). It covers subsurface safety valves including all components that establish tolerances and/or clearances which may affect performance or interchangeability of the SSSVs. It includes repair...
This standard defines the requirements for examination and full refurbishment to be fulfilled for valves at time of periodic inspection of gas cylinders, bundles, drums and trailers.
This European Standard specifies requirements and describes test methods for container valve assemblies for CO2-high-pressure, Inert Gas- or Halocarbon Gas-fire extinguishing systems, which include container valve, actuator and, if applicable, a diptube.
This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for subsea application in offshore pipeline systems meeting the requirements of ISO 13623 for the petroleum and natural...
This European Standard specifies material, construction, inspection and marking requirements for non-refillable metallic gas cartridges with or without a valve for use with portable appliances which comply with the requirements of EN 521. This European Standard is applicable to...
This Standard specifies the requirements and describes test methods for check and non-return valves for CO2, inert gas or halocarbon gas fire exstinguishing systems. Non-return and check valves allow the passage in the direction of flow and they prevent flow in the...
This European Standard specifies the performance requirements, test methods and marking requirements for valved filtering half masks incorporating either gas or combined filters as respiratory protective devices except for escape purposes. It does not cover gas filtering half...
This part of IEC 60534 establishes a theoretical method to predict the external soundpressure level generated in a control valve and within adjacent pipe expanders by the flow of compressible fluids. This method considers only single-phase dry gases and vapours and is based on the...

Specifies types, dimensions and principles of use for gauges. To be read in conjunction with BS EN 629-1:1996
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...
This part of ISO 11363 specifies types, dimensions and principles of use of gauges, to be used in conjunction with the taper threads specified in ISO 11363-1 (i.e. 17E and 25E threads). It provides examples of calculations for thread gauge dimensions on the large end diameter (Annex A) and draws...
