IEC TR 62470:2011 pdfダウンロード。Guidance on techniques for the measurement of the coefficient of friction (COF) between cables and ducts 1 Scope and object This technical report describes three techniques to measure the coefficient of friction (COF) between cables and ducts. For a given technique, cable construction, installation method (pulling, pushing, or blowing), and duct size, the relative values of the COF can give some indication as to the relative ease of installation. The techniques can be used for traditional cables and ducts (see IEC 60794-3-1 0) as well as for microduct cables and microducts (see IEC 60794-5). A fibre or...

IEC TR 62510:2008 pdfダウンロード Standardising the characteristics of electricity 1 Scope This technical report outlines the way in which electricity is now described as a product. Particularly, in Europe and several other areas, for example Brazil and Argentina, as well as in some states in the United States of America. It is, however, rather a unique product because of its intangible and transient nature. Strictly, it is a product that exists only for an instant at a given point of delivery, comes into existence at the same instant at which it is being used and is replaced immediately by a...

IEC TR 62513:2008 pdfダウンロード Safety of machinery – Guidelines for the use of communication systems in safety-related applications Scope This Technical Report addresses the application of closed serial digital communicationssystems (often termed fieldbuses) used for transmission of safety-related data in therealisation of safety functions at machinery. lt offers guidance on the issues that need to beconsidered during the specification, system design, installation, commissioning, modificationand maintenance of such applications. NOTE A closed serial digital communications system is considered to have a fixed number or fixed maximumnumber of participants linked by a transmission system with well-known and fixed properties, and where the...

IEC TR 62517:2009 pdfダウンロード Magnetizing behaviour of permanent magnets 1 Scope It is within the scope of this technical report to describe the magnetizing behaviour of permanent magnets in detail. Firstly, in Clause 3 the relationship between the applied magnetic field strength and the effectively acting internal field strength is reviewed. In Clause 4 the initial state prior to magnetization is discussed. Then, in the main Clause 5, the magnetizing behaviour of all common types of permanent magnets is outlined. The clause is subdivided according to the dominant coercivity mechanisms, namely the nucleation type for sintered Ferrites, RE-Fe-B and SmCo...

IEC TR 62540:2009 pdfダウンロード Radio frequency identification (RFID) of stationary lead acid cells and monoblocs – Tentative requirements Scope IEC/TR 62540, which i a technical report, applies to all stationary lead-acid cells andmonobloc batteries for float charge applications (i.e. permanently connected to a load and toa d.c. power supply), in a static location (i.e. not generally intended to be moved from place toplace) and incorporated into stationary equipment or installed in battery rooms for use intelecom, uninterruptible power supply (UPS), utility switching, emergency power or similarapplications. These batteries are covered by lEC 60896-11, EC 60896-21 and IEC 60896-22 The objective...

IEC TR 62544:2011 pdfダウンロード High-voltage direct current (HVDC) systems – Application of active filters 1 Scope This technical report gives general guidance on the subject of active filters for use in highvoltage direct current (HVDC) power transmission. It describes systems where active devices are used primarily to achieve a reduction in harmonics in the d.c. or a.c. systems. This excludes the use of automatically retuned components. The various types of circuit that can be used for active filters are described in the report, along with their principal operational characteristics and typical applications.
