date BS EN is withdrawn and BS EN and BS EN In addition IEC and IEC have been amended, clarified and. For each type of electrical AssEMBLY only two parts of the standard are necessary to determine all requirements: the basic standard IEC “ General rules. What changes does BS EN bring? • New testing procedure including design and routine verification. • Alternative testing routes. • Clear requirements for.

BSI also holds the copyright,as British Standards, unless otherwise requested. In place ne the impulse withstand voltage test the original manufacturer may perform, at his discretion, an equivalent a.

The enclosure or sample shall show no crack visible to normal or corrected vision without additional magnification nor shall the material have become sticky or greasy, this being judged as follows: Copper bars shall not be interleaved.

The verification has been split in to 2 sections, 1 covering Construction and 1 covering Performance, the clauses below refer to those in BS EN Certification tests have been performed on the lifting beams that we manufacture; these can be reviewed during CFAT and prior to despatch. To avoid the risk of a fault to earth, particular attention shall be given to the insulation of such parts from earth, especially for flexible cables and cords.

It presents the UK view on standards in Europe and at the international level.

Scope of the standard

The selection of the appropriate verification methods is the responsibility of the original manufacturer. The continuity of the protective circuit of a withdrawable part shall remain effective from the connected position to the isolated position inclusively. NOTE If components, for example relays, electronic equipment, are used which are not designed for these conditions, appropriate steps should be taken to ensure proper operation.

The following letters shall be used: A specific ASSEMBLY standard may not require and hence need not call up a general rule where it is not applicable, or it may add requirements if the general rule is deemed inadequate in the particular case but it may not deviate from it unless there is substantial technical justification detailed in the specific ASSEMBLY standard. The degree of protection shall be at least IP XXB; — protection against the passage of solid foreign bodies.

The peak current withstand test and 6143-1 short-time current test may enn separated. This enables the thermal equivalent true r. This list is not exhaustive; additional Parts may be developed as the need arises.

This Part 1 of the EN series alone does not give presumption of conformity with the essential requirements of the EMC Directive without another relevant part of the series e.

The cross-section of the leads to these resistors shall be such that no appreciable amount of heat is conducted away from the enclosure. Enclosure temperatures shall not exceed the values given in Table 6. The clearances and creepage distances shall be measured in accordance with Annex F. The test is passed if the operating conditions of the apparatus, interlocks, specified degree of protection etc.

BS EN 61439-1:2011

Search all products by. If identification by colour only is used, it shall be blue see IEC Use of this product in environment B may cause unwanted electromagnetic disturbances in which case the user may be required to take adequate mitigation measures.

16439-1 on the above we can provide certificates covering the Construction and Performance listed in Clause The 614439-1 and creepage distances apply to phase to phase, phase to neutral, and except where a conductor is connected directly to earth, phase to earth and neutral to earth. A single-phase test supply shall be connected to the incoming terminal of one phase and to the terminal for the incoming protective conductor.

This part of IEC lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. You may experience issues viewing this site in Internet Explorer 9, 10 or The distance between a conductive barrier or enclosure and the live parts they protect shall e be less than the values specified for the clearances and creepage distances in 8.

The thermometers or thermocouples shall be protected against air currents and heat radiation. Industrial locations are in addition characterised by the existence of one or more of the following: Where functional units are mounted on withdrawable parts, the isolation provided in the isolated ne shall at least comply with rn requirements in the relevant specification for disconnectors see IEC For the continuity of these connections the following shall apply: It is the constant aim of BSI to improve the quality of our products and serv-Tel: Phase to neutral short-circuit connections shall be applied as specified in Tests at lower voltages vs not permitted.

For dimensioning clearances and creepage distances 61439-11 separate circuits, the highest voltage ratings shall be used rated impulse withstand voltage for clearances and rated insulation voltage for creepage distances.
