A standardized theoretical measurement of radio frequency (RF) energy using the SI unit watts. It is determined by subtracting system losses and adding system gains.

When two objects in each other's vicinity have different electrical charges, an electrostatic field exists between them. An electrostatic field also forms around any single object that is electrically charged with respect to its environment. An object is negatively charged (-) if it has an(...)

The electric force experienced by a motionless electrically charged test particle at any point in space relative to the source(s) of the field.

The branch of electrical sciences which studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (electromagnetic interference, or EMI) that such energy may induce.

Disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics and electrical equipment.

A physical field produced by electrically charged objects. Also known as EM Field or EMF.

Disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.

A short burst of electromagnetic energy. Also known as EMP or transient distrubance.

Form of energy emitted and absorbed by charged particles which exhibits wave-like behavior as it travels through space.

A version of a passive two-terminal electronic component called an inductor which is designed specifically for blocking higher-frequency alternating current (AC) in an electrical circuit, while allowing lower frequency or DC current to pass.

Sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.

The branch of electrical sciences which studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (electromagnetic interference, or EMI) that such energy may induce.

A physical field produced by electrically charged objects. Also known as EM Field or EMF.

Disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.

Filter that is placed between an electronic equipment and a line external to it, to attenuate conducted radio frequencies between the line and the equipment.

A receiver with defined IF-Bandwidths (typically 200 Hz, 9 kHz, 120 kHz, 1 MHz) and standardized detector modes (peak, quasipeak, average, rms, CISPR-AV and CISPR-RMS, RMS-Average). It uses a preselection for an improved dynamic range.

A short burst of electromagnetic energy. Also known as EMP or transient distrubance.

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(...)

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. These limits however, may not provide full protection against disturbances caused to radio and TV(...)

This standard defines : - the requirements and(...)

Specifies the safety and performance requirements for doors, gates and barriers, intended for installation in areas in the reach of persons, and for which the main intended uses are giving safe access for goods and vehicles accompanied or driven by persons in industrial, commercial or(...)

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.(...)

This standard addresses detailed system requirements (Clause 4), general test conditions, verification requirements at system level, and test methods at subsystem and equipment level (Clause 5) as well as informative limits (Annex A).
