IEC 60947-5-1:2003+A1:2009 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear and controlgear. It applies to control circuit devices having a rated voltage not exceeding 1 000 V a.c. (at a frequency not exceeding 1 000 Hz) or 600 V d.c. The technical content is therefore identical to the base edition and its amendment…

IEC/TS 61000-3-5:2009 deals with emission of disturbances due to voltage fluctuations and flicker. The recommendations in this Technical Specification are applicable to electrical and electronic equipment that has a rated input current exceeding 75 A per phase and is intended to be connected to a public low-voltage a.c. distribution system. Recommendations that specify information enabling a…

IEC 62453-1:2009 presents an overview and guidance for the IEC 62453 series. It explains the structure and content of the IEC 62453 series (see Clause 5); provides explanations of some aspects of the IEC 62453 series that are common to many of the parts of the series; describes the relationship to some other standards.

ISO/TS 10128:2009 specifies three methods for the adjustment of the digital content data that is input to a printing system to achieve consistency in the printed results among a number of presses printing to the same general aim conditions. These three methods are generally identified as the matching of tone value curves, the use of near-neutral scales, and the use of CMYK to CMYK multi…

IEC 60601-2-54:2009 applies to the basic safety and essential performance of medical electrical equipment and medical electrical systems intended to be used for projection radiography and radioscopy. The minimum safety requirements specified in this particular standard are considered to provide for a practical degree of safety in the operation of ME equipment for radiography and radioscopy.…

IEC 61243-1:2003+A1:2009 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and frequencies of 50 Hz and/or 60 Hz. This part applies only to voltage detectors of capacitive type used in contact with the part to be tested, as a complete device including its insulating element or as a separate…

IEC 61547:2009 for electromagnetic immunity requirements applies to lighting equipment which is within the scope of IEC Technical Committee 34, such as lamps, auxiliaries and luminaires, intended either for connecting to a low voltage electricity supply or for battery operation. Excluded from the scope of this standard is equipment for which the immunity requirements are formulated in other IEC…

ISO/TR 834-2:2009 establishes general principles for measuring the uniformity of furnace exposure of samples tested in accordance with the requirements of ISO 834-1. ISO/TR 834-2:2009 specifies the type and location of instrumentation used to measure the temperature, velocity and oxygen content near the surface of simulated test samples. The surface of the simulated sample facing the furnace is…

ISO 659:2009 specifies a reference method for the determination of the hexane extract (or light petroleum extract), called the “oil content”, of oilseeds used as industrial raw materials. The procedure for sunflower seed is different from those for other seeds as it includes an additional moisture content determination after the seed has been ground to prepare the test sample. The method has been…
