BS EN 61000-3-3:2013+A1:2019 - TC

Tracked Changes. Electromagnetic compatibility (EMC). Limits. Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and not subject to conditional connection

Status : Current, Work in hand   Published : November 2019


What is a tracked changes standard?

A tracked changes version of a Standard indicates the changes made, during the standards revision process, between the active standard and its previous version. Additions, deletions, and other formatting and/or content revisions are clearly displayed as underlined and strikethrough texts, ensuring all changes made between the two documents are quickly and easily identified. This version of the standard includes both a copy of the new standard, along with a track changes version.

What is this standard about?

This international electrotechnical standard gives guidance on the acceptable levels of voltage variation and voltage flicker caused by rapid power supply voltage fluctuations. This results in light luminance fluctuation. By limiting the voltage variations, flicker can be limited.

The standard also offers manufacturers an effective way to demonstrate conformity with the EMC and Radio Equipment Directives, which is necessary for the CE marking of their products.

Who is this standard for?

  • EMC test laboratories
  • Information technology equipment manufacturers (design managers or regulatory/compliance engineers)
  • Manufacturers of lighting and electrical appliances
  • Electrical utilities

Why should you use this standard?

BS EN IEC 61000-3-3:2013 deals with limiting voltage fluctuations and flicker impressed on the public low-voltage system. It specifies the limits of voltage changes which may be produced by electrical and electronic equipment tested under specified conditions and gives guidance on methods of assessment.

This standard applies to equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection.

BS EN IEC 61000-3-3 has the status of a product family standard within the BS EN 61000 series.

NOTE 1: Compliance with this standard and its amendment provides presumption of conformity with the specified essential requirements of the EMC Directive and the Radio Equipment Directive (RED).

What’s changed since the last update?

This is a small amendment to the standard, not a revision. It mainly affects the test conditions in Annex A for lighting equipment, raising the exemption level for voltage fluctuation testing from 200W to 600W for LED lamp luminaires. At the same time some editorial clarifications have been made in other clauses.

NOTE 2: This 2019 version supersedes the 2013, un-amended version which will nevertheless not be withdrawn for three years, during which time both versions will be current.
