Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equi...
Specifies limits for harmonic current emissions applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems. The tests according to this standard are type tests. Test conditions for particular equipment are given in annex C. For systems with nominal voltages less than 220 V (…
Methods of measurement for minidisc recorders/players
Specifies the measuring methods for recording and reproducing equipment for MiniDiscs that conform to IEC 61909. Lists and defines the characteristics affecting the performance of MiniDisc recorders or players, establishes conditions and methods of measurement of those characteristics, and standardizes the presentation of the results.
Components for low-voltage surge protective devices - Part 311: Specification for gas discharge tube...
Gas discharge tubes (GDTs) are used for applications up to 1 000 V a.c. or 1 500 V d.c. in communication or signalling circuits. They are defined as a gap, or series of gaps, in an enclosed discharge medium other than air. They are designed to protect apparatus or personnel, or both, from high transient voltages. This standard does not specify requirements applicable to complete surge protective…
Measurement microphones - Part 5: Methods for pressure calibration of working standard microphones b...
Applies to working standard microphones with removable protection grids meeting the requirements of IEC 61094-4 and to laboratory standard microphones meeting the requirements of IEC 61094-1.
Describes methods of determining the pressure sensitivity by comparison with either a laboratory standard microphone that has been calibrated according to IEC 61094-2, or another working standard…
Is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. This standard concerns only ladders made of synthetic material. These ladders are used, to provide access, generally on overhead line…
