  • IEC 61000-4-28:1999+A1:2001+A2:2009 establishes a reference for evaluating the immunity of electric and electronic equipment when subjected to variations of the power frequency. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial(...)
  • IEC 61000-4-29 establishes a common and reproducible basis for testing electrical and electronic equipment when subjected to voltage dips, short interruptions or voltage variations on d.c. power ports. This standard defines: - the range of test levels; - the test generator; - the test set-up;(...)
  • IEC 61000-4-30:2008 defines the methods for measurement and interpretation of results for power quality parameters in 50/60 Hz a.c. power supply systems. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method's(...)
  • IEC 61000-4-33 provides a basic description of the methods and means (e.g., instrumentation) for measuring responses arising from high-power transient electromagnetic parameters. These responses can include: - the electric (E) and/or magnetic (H) fields (e.g., incident fields or incident plus(...)
  • IEC 61000-4-34:2005+A1:2009 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and(...)
  • IEC 61000-4-36:2014(E) provides methods to determine test levels for the assessment of the immunity of equipment and systems to intentional electromagnetic interference (IEMI) sources. It introduces the general IEMI problem, IEMI source parameters, derivation of test limits and summarizes(...)
  • This part of 61000-5 defines how protective devices for conducted disturbance proposed for HEMP protection shall be specified. It is intended to be used for the harmonization of existing or future specifications issued by protective device manufacturers, electronic equipment manufacturers,(...)
  • IEC 61000-5-7 describes performance requirements, test methods and classification procedures for degrees of protection provided by empty enclosures against electromagnetic disturbances for frequencies between 10 kHz and 40 GHz. The shielding protection is measured for the purpose of(...)
  • IEC 61000-6-7:2014 is intended to be used by suppliers when making claims for the immunity of equipment intended for use in safety-related systems against electromagnetic disturbances. This standard should also be used by designers, integrators, installers, and assessors of safety-related(...)
  • Specifies requirements for the performance characteristics of neutron ambient dose equivalent (rate) meters, and prescribes the methods of testing in order to determine compliance with this standard. Specifies general characteristics, general test procedures, radiation characteristics,(...)
  • IEC 61010-2-010:2014 specifies safety requirements for electrically powered laboratory equipment for the heating of materials, where the heating of materials is one of the functions of the equipment.
  • Specifies the complete safety requirements for control equipment (e.g. programmable controller (PLC)), the components of Distributed Control Systems, I/O devices, Human Machine Interface (HMI)).
  • Applies to portable, transportable or installed assemblies intended to measure environmental air kerma rates from 30 nGy h-1 to 10 µGy h-1 due to X or gamma radiation of energy between 50 keV and 1,5 MeV.
  • Applies to portable or installed integrating assemblies intended to measure environmental air kerma due to X or gamma radiation of energy between 50 keV and 1,5 MeV by integration of the detector's signal
  • Provides basic performance and design requirements for beta and/or photon high-range dose and dose rate measuring instruments used for prompt assessment of radiological emergencies. Specifies the general characteristics, operating characteristics, electrical, mechanical, safety and(...)
  • Provides guidelines for the design principles, the location, the application, the calibration, the operation, and the testing of installed equipment for continuously monitoring local gamma radiation dose rates in nuclear power plants under normal operation conditions and anticipated(...)
  • Specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: - protection of persons against access to hazardous parts inside the enclosure; - protection of the equipment inside the enclosure against ingress of solid foreign objects.
  • Provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally.
  • Provides details of the test procedure to be employed for the measurement of the density of smoke emitted from cables burning under defined conditions. It describes the means of preparing and assembling cables for test, the method of burning the cables, and gives recommended requirements for(...)
  • Defines standard routines for software access to a FASTBUS system, a standardized modular high-speed data acquisition and control system defined in IEC 60935. The object is to provide standard routines that have the same meaning to all users so as to minimize duplication of software effort,(...)
