Short circuit withstand strength This is principally the same set of tests as per the previous version of the standard, with a few amendments. Annex D of the BS EN standard provides a list of 13 categories or verifications required, what testing method can be used and what comparisons can be made.
InGoogle was founded, the first Apple iMac was introduced and the legendary Windows 98 was released by Microsoft. In order to optimise testing time, the standard allows derivation of the rating bs en 61439 similar variants without testing, assuming the ratings of critical variants have been established by test.
Although Windows 98 6143 long been consigned to history, the new industry standard — BS EN — only came into force on November 1, No longer can you fit a device into a compartment and rate it at a level it would not be capable of carrying without exceeding the limits set by the standard. Strength of materials and parts This looks at the suitability of plastics and metals to prove the long term capabilities of the equipment.
Before bs en 61439 introduction of the new standard, testing every conceivable variant was not only time vs and costly, but impractical.
You may experience issues viewing this site in Internet Explorer 9, 10 or To ensure JME are fully certified to manufacture electrical control panels to the new Terminals for external conductors This, again, puts the onus on the panel builder to ensure that the contractor will be able to terminate his cables on to the switchboard.
It states that the capabilities of each bs en 61439 will be verified in two stages: Switchgear and Control Gear assemblies are multifaceted and have an endless number of component combinations.
