Fibre optic interconnecting devices and passive components - Basic test and measurement procedures -...
IEC 61300-2-12:2009 evaluates the ability of a passive fibre optic device or a closure to withstand impacts likely to be encountered during usage. The impact may be a localized impact, a series of impacts with hard objects, or an impact normally associated with dropping the device. In this third edition, the impact test with a steel ball has been added. The contents of the corrigendum of June…
Electromagnetic compatibility (EMC) - Part 3-5: Limits - Limitation of voltage fluctuations and flic...
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…
Low-voltage switchgear and controlgear - Part 5-1: Control circuit devices and switching elements - ...
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…
Field device tool (FDT) interface specification - Part 1: Overview and guidance
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.

Graphic technology — Methods of adjustment of the colour reproduction of a printing system to match ...
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…
Medical electrical equipment - Part 2-54: Particular requirements for the basic safety and essential...
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.…
Live working - Voltage detectors - Part 1: Capacitive type to be used for voltages exceeding 1 kV a....
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…
Equipment for general lighting purposes - EMC immunity requirements
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…
