Scope 1.1 This Standard covers the design, qualification, installation, commissioning, operation, maintenance, testing, inspection, and documentation requirements for systems providing heat removal from the reactor core to the ultimate heat sink(s) for water-cooled nuclear power plants during outages. 1.2 This Standard covers only fuel cooling within the reactor core and does not cover…

IEC/TS 60034-2-3:2013 specifies test methods for determining losses and efficiencies of converter-fed AC induction motors within the scope of IEC 60034-1. The AC induction motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800-2, IEC 61800-4 or IEC/TS 61800-8. The additional harmonic losses determined by use of this technical specification are for comparison…

IEC 60079-14:2013 contains the specific requirements for the design, selection, erection and initial inspection of electrical installations in, or associated with, explosive atmospheres. Where the equipment is required to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional protection requirements may be necessary. The…

ISO 1081:2013 specifies the terms and definitions, in English and French, relating to V-belt drives, V-belts, hexagonal belts, joined V-belts and the corresponding V-grooved pulleys, V-ribbed belt drives, V-ribbed belts and V-ribbed pulleys, as well as the corresponding symbols.The general definitions are valid irrespective of the system describing the pulleys. The dimensions of pulley grooves…
