Overview

EN 61000-3-3:2013/prAA (CLC draft amendment prAA, Feb 2023) is a CENELEC/C LC document amending the European standard for electromagnetic compatibility (EMC) that limits voltage fluctuations and flicker produced by equipment with a rated input current ≤ 16 A per phase. The amendment updates scope, test conditions and normative references to clarify compliance assessment for devices intended for public low-voltage distribution systems (220–250 V line-to-neutral, 50 Hz). It also responds to identified negative RED assessment issues and refines measurement and testing requirements.

Key topics and requirements

• Scope and applicability
  • Equipment with rated input current ≤ 16 A per phase, connected to public low-voltage supplies (220–250 V L–N, 50 Hz).
  • Addresses voltage change, flicker and methods of assessment at the supply/user interface.
• Limits and assessment
  • Specifies limits for voltage fluctuations and flicker (Pst, Plt and related parameters) and guidance on methods of measurement and evaluation.
  • Emphasizes that limits relate to voltages experienced at the interface between public supply and the user’s installation.
• Test and measurement updates
  • Revision of Clause 6: wording changes (e.g., “measurement uncertainty” → measurement accuracy), updated reference impedance definition (Zref per Figure 1), and clarified general test conditions (“supplied to the user”).
  • Annex edits provide specific test conditions for device families (copying machines, printers, grills, HVAC, welding equipment, coffee machines, etc.).
  • Removal of conditional references to IEC/TR 60725 and updates to normative references such as IEC 61000-3-2:2018 and IEC 60974-1:2017 where applicable.
• Compliance outcome
  • If measured flicker parameters exceed limits, the equipment cannot be declared compliant under this part of IEC 61000 (previously some references directed to IEC 61000-3-11; the amendment removes those conditional paths in several clauses).

Applications and who uses this standard

• Manufacturers of household and commercial electrical/electronic equipment (appliances, printers, HVAC, welding units) to design products that meet flicker and voltage fluctuation limits.
• Test laboratories and conformity assessment bodies for type testing and certification against EMC flicker criteria.
• EMC/Compliance engineers and product designers implementing mitigation (soft-starts, active control, filtering) to avoid adverse flicker effects on lighting and other consumers.
• Regulators and notified bodies using the standard to verify compliance with EU Directives (including links to the Radio Equipment Directive where relevant).

Related standards

• IEC/EN 61000-3-2 (harmonic current limits)
• IEC 61000-3-11 (equipment ≤ 75 A, conditional connection) - referenced in bibliography
• IEC 60974-1 (welding equipment requirements)

This amendment refines EN 61000-3-3’s practical test conditions and normative links, improving clarity for manufacturers and conformity assessors responsible for limiting flicker and maintaining power quality on public low-voltage networks.

For relationship with EU Directive(s) / Regulation(s), see informative Annexes ZZA and ZZB, which are an
integral part of this document.
1 Replacement of Clause 1, “Scope”
Replace the content of Clause 1 with the following:
“This part of IEC 61000 covers the limitation of voltage fluctuations and flicker impressed on the public low-
voltage system.
It specifies limits of voltage changes which are produced by an equipment tested under specified conditions
and gives guidance on methods of assessment.
This part of IEC 61000 is applicable to electrical and electronic equipment having a rated 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.
NOTE 1 The limits in this document relate to the voltage changes experienced by consumers connected at the
interface between the public supply low-voltage network and the equipment user’s installation. Consequently, if the actual
impedance of the supply at the supply terminals of equipment connected within the equipment user’s installation exceeds
the test impedance, it is possible that supply disturbance exceeding the limits could occur.
NOTE 2 The limits in this document are based mainly on the subjective severity of flicker imposed on the light from
230 V 60 W coiled-coil filament lamps by fluctuations of the supply voltage.”
2 Modifications to Clause 2, “Normative references”
Delete the following reference:
IEC/TR 60725, Consideration of reference impedances and public supply impedances for use in determining
disturbance characteristics of electrical equipment having a rated current ≤ 75 A per phase
Replace “IEC 60974-1:2017” with “IEC 60974-1:2017 ”.
Replace
IEC 61000-3-2, Electromagnetic compatibility (EMC) – Part 3-2: Limits – Limits for harmonic current emissions
(equipment input current ≤ 16 A per phase)
with
IEC 61000-3-2:2018, Electromagnetic compatibility (EMC) – Part 3-2: Limits – Limits for harmonic current
emissions (equipment input current ≤ 16 A per phase)
Delete the following reference:
IEC 61000-3-11, Electromagnetic compatibility (EMC) – Part 3-11: Limits - Limitation of voltage changes,
voltage fluctuations and flicker in public low-voltage supply systems - Equipment with rated current ≤ 75 A and
subject to conditional connection
3 Modification to Clause 3, “Terms and definitions”
Replace the entire term entry 3.13 with the following:
“
3.13
conditional connection
connection of equipment requiring the user’s supply at the interface point to have an impedance lower than
the reference impedance Zref
“
As amended by IEC 60974-1:2017/A1:2019.
As amended by IEC 61000-3-2:2018/AMD1:2020.
4 Modification to Clause 5, “Limits”
Delete the last sentence of the 1st paragraph “Tests made to prove compliance with the limits are considered
to be type tests.”
5 Modification to 6.1, “General”
Delete the following first two paragraphs:
“Tests need not be made on equipment which is unlikely to produce significant voltage fluctuations or flicker.
Where it is considered necessary to conduct tests, the equipment shall comply with all limits in Clause 5 for
the tests described in Annex A unless there are specific exclusions for a particular type of equipment.
It may be necessary to determine, by examination of the circuit diagram and specification of the equipment
and by a short functional test, whether significant voltage fluctuations are likely to be produced.”

Change the title of the clause from “Measurement uncertainty” to “Meas
