IEC/TR 62540:2009(E) applies to all stationary lead-acid cells and monobloc batteries for float charge applications (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS),…

IEC/TS 62578:2009(E) describes the operation conditions and typical characteristics of Active Infeed Converters (AIC) of all technologies and topologies which can be connected between the electrical power supply system (lines) and a current or voltage stiff d.c.-side and which can convert electrical power (active and reactive) in both directions (generative or regenerative). The following is…

ISO 15136-1:2009 provides requirements for the design, design verification and validation, manufacturing and data control, performance ratings, functional evaluation, repair, handling and storage of progressing cavity pumps for use in the petroleum and natural gas industry. ISO 15136-1:2009 is applicable to those products meeting the definition of progressing cavity pumps (PCP) included herein.…

ISO 13624-1:2009 pertains to the design, selection, operation and maintenance of marine riser systems for floating drilling operations. Its purpose is to serve as a reference for designers, for those who select system components, and for those who use and maintain this equipment. It relies on basic engineering principles and the accumulated experience of offshore operators, contractors, and…

ISO 8536-6:2009 specifies the shape, dimensions, material, performance requirements and labelling for the type of closure for infusion bottles, as described in ISO 8536-1, which are used in connection with the freeze-drying (or lyophilization) of drugs and biological materials. The dimensional requirements are not applicable to barrier-coated closures. Closures specified in ISO 8536-6:2009 are…

Preface This is the second edition of CAN/CSA-C22.2 No. 60601-2-31, Medical electrical equipment - Part 2-31: Particular requirements for the basic safety and essential performance of external cardiac pacemakers with internal power source, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 60601-2-31 (second edition,…

IEC 61000-4-7:2002+A1:2008 applies to instrumentation intended for measuring spectral components in the frequency range up to 9 kHz which are superimposed on the fundamental of the power supply systems at 50 Hz and 60 Hz. For practical considerations, this standard distinguishes between harmonics, interharmonics and other components above the harmonic frequency range, up to 9 kHz. Defines the…

ISO 7240-18:2009 specifies requirements, test methods and performance criteria for input/output devices connected to a transmission path of a fire detection and alarm system used to receive and/or transmit signals to or from the transmission path, necessary for the operation of the fire detection and fire alarm system and/or fire protection system. An input/output device can be a physically…

IEC 60364-5-52:2009 deals with the selection and erection of wiring systems. This third edition cancels and replaces the second edition, published in 2001, and constitutes a technical revision. The main changes with respect to the previous edition are as follows: - Subclause 521.4 introduces minor changes with regard to busbar trunking systems and powertrack systems. - Subclause 523.6…
