4.1 The examination is performed by passing the tube lengthwise through or near an eddy current sensor energized with alternating current of one or more frequencies. The electrical impedance of the eddy current sensor is modified by the proximity of the tube. The extent of this...
This standard gives guidance on writing the technical specification for the procurement of water tube boilers for use in electricity generating stations (power stations). This guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear...
5.1 Dissolved oxygen is detrimental in certain boiler and steam cycles because it may accelerate corrosion. Concentrations above 10 µg/L are unacceptable in many high-pressure boiler systems. The efficiency of dissolved oxygen removal from boiler feedwater by chemical or...

IEC 60613:2010 applies to X-ray tube assemblies either with a rotating anode X-ray tube or a stationary anode X-ray tube, intended for use in medical diagnosis. For an X-ray tube head, its X-ray tube assembly aspects are also within the scope. IEC 60613:2010...
1.1 This test method covers the use of an impedance tube, alternatively called a standing wave apparatus, for the measurement of impedance ratios and the normal incidence sound absorption coefficients of acoustical materials. 1.2 The values stated in SI units are to be regarded as standard....
This specification covers round wires made from UNS N02211, UNS N10001, or N03300 nickel alloy or molybdenum, with diameters within a specified range, for winding electron tube grid laterals. The wires are classified into five classes based on tensile properties. All wires should conform to...
This standard applies to straight thermocouples for the nominal pressure level PN 1, which are made of standardized components (connection head, protection tube and thermocouple(s)). Details regarding the operational areas of the thermocouples and the use of protection tubes are part...
