Overview
EN 60456:2016/A12:2023 is a CENELEC amendment that updates the European test standard EN 60456:2016 for clothes washing machines for household use. It specifies harmonized methods of measuring washing machine performance (washing, rinsing, energy and water use, cycle time, moisture content, noise, low-power modes and related metrics). The amendment (A12, Oct 2023) introduces new test procedures, definitions and normative annexes to reflect technological, regulatory and market changes.
Key topics and technical requirements
- Combined test series (eco 40‑60): Introduces the new eco 40–60 programme as the reference for the combined test sequence, tested with default settings and given temperature.
- Load definitions: Adds a quarter load (≈ 25% of rated capacity) as a distinct test load in addition to full and half loads; quarter load table referenced in Annex ZA.
- Test repetition and timing: Combined test runs per treatment: 3 tests (full load), 4 tests (half load), 3 tests (quarter load). Time between sequential runs reduced from 2 hours to 1 hour.
- Normalization and load ageing: The normalization run is now included in load age calculations. Maximum combined usages for base loads revised:
- ≥ 4.5 kg: 35–60 normalizations + tests
- < 4.5 kg: 30–67 normalizations + tests
- New and revised annexes:
- Annex ZD - Modified procedure for measuring low power modes (standby/off/left-on).
- Annex ZE - Test method for temperature inside the laundry load.
- Annex ZF - Test for rinsing effectiveness by measuring surfactant content on textiles.
- Annex ZB - Replaced to define procedures for multi‑drum washing machines and multi‑drum modes.
- Annex B - Introduces new reference powder detergent IEC‑P (replacing IEC‑A*; sodium percarbonate replaces sodium perborate due to REACH).
- Other updates: Definitions (terms like combined rated capacity, simultaneous programme), revised tolerances for remaining moisture content, and normative references (noise, low power standards).
Applications and who uses it
- Appliance manufacturers - for product development, internal performance verification and conformity evidence for CE marking.
- Test laboratories and certification bodies - to perform repeatable, standardized performance tests for energy labelling and ecodesign compliance.
- Regulators and market surveillance - to verify declared energy/water figures and low‑power behaviour.
- Retailers & specifiers - to validate comparative performance claims in product listings.
- R&D teams - to benchmark wash, rinse and temperature control innovations.
Related standards & regulatory links
- Linked to EU energy labelling and ecodesign requirements (see Annexes ZZA, ZZB).
- Normative references include standards for acoustical noise (EN 60704‑2‑4) and low power measurement (EN 50564 / EN 50643).

European foreword
This document (EN 60456:2016/A12:2023) has been prepared by CLC/TC 59X “Performance of household
and similar electrical appliances”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2024-04-27
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2026-10-27
conflicting with this document have to be
withdrawn
This document introduces the following technical modifications:
a) The programme to be tested for the combined test series is the new introduced eco 40-60
programme. This programme needs to be tested with default settings with the given temperature.
b) The test loads that have to be used for testing are full, half and quarter of the rated capacity of the
washing machine. Therefore, a new quarter load is introduced and defined to be approximately a
quarter of the rated capacity (see Table ZA.15). The quarter load is treated as a separate load and not
created by dividing full load or half load.
c) The number of test runs per treatment for the combined test series changed to 3 tests with full load, 4
tests with half load and 3 tests with quarter load.
d) The time between two subsequent test runs within one day changed from 2 h to one hour.
e) The normalization run is included in the calculation of the load age. The maximum number of usages for
base load with a load mass greater or equal to 4.5 kg was changed to be between 35 and 60
normalization runs and test runs and the maximum number of usages for base load with a load mass
less than 4.5 kg was changed to be between 30 and 67 normalization runs and test runs.
f) Annex ZE is integrated, which defines the test procedure for temperature inside the load.
g) Annex ZF is integrated, which defines the test procedure for rinsing effectiveness.
h) The procedure to measure low power modes is modified (see Annex ZD).
i) Specific weighting factors are introduced for the calculation of the weighted average value of the
combined test series.
j) Annex ZB Tolerances and control procedures is deleted. Annex ZB is replaced by a new Annex ZB which
defines the testing procedure for multi-drum washing machines.
k) A new standard powder detergent IEC-P is introduced (see Annex B), that substitutes the standard
powder detergent IEC-A* by replacing the bleach component sodium perborate with sodium percarbonate
due to Commission Regulation (EU) 2020/171 amending Annex XIV to Regulation (EC) No 1907/2006 of
the European Parliament and of the Council concerning the Registration, Evaluation, Authorization and
Restriction of Chemicals (REACH). According to REACH Regulation Article 56, the substances which are
listed in the Annex XIV cannot be used or placed on the market after the “sunset date”, unless the
authorization is granted. Sodium perborate has a sunset date of 27th of May 2023 after having been
classified as toxic to reproduction.
l) The tolerances for the remaining moisture content in Table E.2 are adapted, due to change in the
commercially available material.
m) In normative clauses undated references were dated.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a standardization request addressed to CENELEC by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annexes ZZA and ZZB, which are an integral part of
this document.
