Contract requirements A British Standard does not purport to include all the necessary provisions of a contract. The tests shall be carried out somewhere within the specified operating environmental range for the apparatus and at its rated supply voltage, unless otherwise indicated in the basic standard. Residential, commercial and light industry. The configuration and mode of operation during measurement shall be precisely noted in the test report. Radiodisturbances, electromagnetic compatibility, tests, equipment protection.

Measurements shall be performed in well-defined and reproducible conditions for each type of disturbance. Apparatus intended to be connected to an industrial power network or to special power supply sources are covered by another generic standard.

In such a case it is required that the decision not to measure be recorded in the test report. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. Users of British Standards should make sure that they possess the latest amendments or editions. For undated references the latest edition of the publication referred to applies. The purchaseduser shall be informed ifspecial measures have to be taken to achieve compliance, e.

An attempt shall be made to maximize the emission by varying the configuration of the test sample. It is a compromise between cost and the performance of extra electronic front end circuits, the so called active power factor correcting circuits.

Locations which are characterized by being supplied directly at low voltage from the public mains are considered to be residential, commercial or light industrial. Only applies to equipment containing electronic circuits. The result is that high peak currents flow during a short time. At the present time, bmw 5 brochure pdf the decision of the Council of Ministers on the proposal is awaited.

The resulting neutral conductor can be larger than the current in each of the phases R, S and T. From Wikipedia, the free encyclopedia. Although these circuits use inductors, these are cheap, lightweight and small ferrite core components.

Test requirements are specified for each port considered. Measurements shall only be carried out where the relevant ports exist. Users of British Standards are responsible for their correct application. Fault conditions of apparatus are not taken into account.

The tops and valleys of the sine wave were flattened. It defines the protection requirements, and related conformity procedures. With present day components with wide use, e. These emission limits represent essential electromagnetic compatibility requirements.

It may be determined from consideration of the electrical characteristics and usage of a particular apparatus that some of the measurements are inappropriate and therefore unnecessary. Revisions British Standards are updated by amendment or revision. These normative references are cited at the appropriate places in the text and the publications are lisfed hereafter.

It is incorporated by Royal Charter. During this peiiod, products manufactured in one Member State which do not conform to the Directive would be required to conform to the regulations of the Member State in which they are marketed. Compliance with a British Standard does not of itself confer immunity from legal obligations.
