    Definition
  • Specifies test methods to be used in conjunction with CISPR 11 to determine radiofrequency emission; relevant standards and test methods for harmonic current emission, voltage fluctuation and flicker. Also defines immunity requirements and test methods for continuous and transient, conducted(...)
  • Applies to free standing operation a.c. static transfer systems (STS) intended to ensure the continuity of load supply through controlled transfer, with or without interruption of power, from two or more independent a.c. sources.includes requirements for the switching elements, their control(...)
  • This standard deals with safety related technical verification during commissioning. The following parts are dealt with in this standard (see Figure 1) A Bulk material to be stored B Storage space limited by the silo structure C Charging D Discharging E Associated and additional equipment(...)
  • This standard is applicable to continuously-operating equipment and systems designed for the mechanical handling of bulk materials only, including mobile machines. This standard relates to the following groups of equipment. - Fixed equipment, such as belt, apron, screw "en masse" conveyors and(...)
  • This standard applies to mechanical conveyor devices designed exclusively for moving unit loads continuously on a predefined route from the loading to the unloading point, possibly with varying speed or cyclically. It also applies to continuous conveyors which are built into machines or(...)
  • This European standard deals with the technical requirements to minimise the risks due to the hazards listed in clause 4, which can arise during operation and maintenance of fixed belt conveyors and systems as defined in 3.1 to 3.2.4 and designed for continuously conveying loose bulk materials(...)
  • This European Standard specifies requirements for separate hold-open devices and also for hold-open mechanisms incorporated in a door closer. Electrically powered hold-open devices for swing doors manufactured according to this European Standard can hold a swing door at a fixed position or can(...)
  • This European Standard specifies the emission limits in relation to electromagnetic disturbances and test conditions for lifts, escalators and moving walks, which are intended to be permanently installed in buildings.
  • Specifies the immunity performance criteria and test levels for apparatus used in lifts, escalators and moving walks which are intended to be permanently installed in buildings including the basic safety requirements in regard to their electromagnetic environment. These levels represent(...)
  • Applies to industrial trucks regardless of the power source (called only trucks) as defined in ISO 5053, variable reach trucks and their electrical/electronic systems when used in Residential, Commercial, Light Industry and Industrial Environment. This standard defines : - the requirements and(...)
  • Provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of construction machinery with respect to free trade of goods in the European Union. It deals with functional EMC requirements under typical EMC environmental conditions.
  • Deals with the technical requirements to minimize the risks due to the hazards listed in clause 4, which can arise during installation , operation and maintenance of permanently installed equipment and systems for the power driven parking of motor vehicles, as defined in 3.1 to 3.4 below.(...)
  • Specifies requirements for the electromagnetic compatibility (EMC) for electrical apparatus for the detection and measurement of combustible gases, toxic 1) gases or oxygen. This standard applies to apparatus intended for use in residential, commercial and light-industrial environments as well(...)
  • Specifies requirements for a bit-orientated interface system between a single controlling device and control circuit devices as defined in BS EN 60947-1, connected by an unshielded, untwisted two-wire cable carrying data and power.
  • This collateral standard applies to HBES switches with a working voltage not exceeding 250 V a.c. and a rated current up to and including 16 A. for household and similar fixed electrical installations either indoors or outdoors and to associated electronic extension units. It applies – to HBES(...)
  • This European Standard is intended to give general minimum frame requirements for units that are independent of the technology used for switching and/or monitoring of individual or group of lamps in an AGL series circuit. This European Standard • applies to the units that are directly(...)
  • Specifies limits and methods of measurement for disturbance emissions and immunity characteristics of aftermarket equipment (ESAs) which are referenced by Automotive EMC Directive 2004/104/EC, Annex I, 3.2.9, and which are not related to immunity-related functions of vehicles as defined in(...)
  • Applies to power frequency overvoltage protection devices (hereafter referred to as “POP”) for household and similar uses, with a rated frequency of 50 Hz, a rated voltage 230 V a.c. (between phase and neutral), intended to be used in combination with a main protective device being either a CB(...)
  • Applies to the generation of electromagnetic energy from sound and television receivers for the reception of broadcast and similar transmissions and from associated equipment. CISPR 13:2009 describes the methods of measurement applicable to sound and television receivers or associated(...)
  • Applies to the emission (radiated and conducted) of radio frequency disturbances from: - all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for(...)
