EN IEC 62841-4-3:2021/A12:2026 is a CENELEC amendment to EN IEC 62841-4-3:2021 for pedestrian controlled walk-behind lawnmowers. It updates safety-related wording for marking, instructions, noise declaration, and battery isolation and disconnection, so manufacturers and conformity assessors know what the revised European text expects. The amendment sits within the EN IEC 62841 series for electric motor-operated hand-held tools, transportable tools and lawn and garden machinery.
What does EN IEC 62841-4-3:2021/A12:2026 specify?
EN IEC 62841-4-3:2021/A12:2026 specifies modifications to the European standard for pedestrian controlled walk-behind lawnmowers. It is an amendment text, not a standalone product standard, and it changes selected clauses and annexes of EN IEC 62841-4-3:2021.
The document is organized as numbered modifications to Clause 1, Clause 8, Clause 18, Clause 19, Clause 20 and Annexes I, K, L, CC, ZA and ZZ. Those annexes carry the technical detail for noise and vibration, battery safety, foot protection testing, references and the link to EU machinery legislation.
| Annex | What it covers |
|---|---|
| Annex I | Measurement, declaration and verification of noise and vibration emissions |
| Annex K | Battery tools and battery packs |
| Annex L | Battery tools and battery packs provided with mains connection or non-isolated sources |
| Annex CC | Rotary lawnmower foot protection test |
| Annex ZA | Normative references to international publications and their European publications |
| Annex ZZ | Relationship with Directive 2006/42/EC |
What are the key requirements of EN IEC 62841-4-3:2021/A12:2026?
Marking and instructions
EN IEC 62841-4-3:2021/A12:2026 changes Clause 8 so that, for rotary lawnmowers, cutting means that can be replaced during user maintenance are marked with the part number(s) and the manufacturer, importer or supplier. In practice, this supports spare-part identification and traceability during servicing.
The amendment also changes the machine mass declaration. The stated mass includes a supply cord of at least 10 m, if present, in addition to the items already counted under the base requirement. That matters because buyers and users need a weight figure that matches the machine as supplied.
Noise declaration and verification
EN IEC 62841-4-3:2021/A12:2026 revises Annex I.2.9 so that the A-weighted emission sound pressure level is declared as a dual number value with its uncertainty, using the LpA and KpA format from ISO 4871:1996. The A-weighted sound power level, LWA, is declared both as a measured value and as a guaranteed value.
In practice, this means noise documentation has to show both the measured result and the guaranteed figure in the required form. Test laboratories and technical files need to match that declaration format.
Battery machines and servicing safety
EN IEC 62841-4-3:2021/A12:2026 adds and replaces requirements in Annex K and Annex L for machines with an integral battery. Such machines need an isolation device that disconnects at least one pole of the battery from the serviceable region, clearly shows the disconnected state, and prevents accidental reconnection.
The amendment also requires a means of disconnecting the cutting means motor circuit that is separate from the operator presence control and easy to reach in the normal operating position. This can be combined with a disabling device or an isolation device. In practice, servicing and user maintenance need a clear, deliberate way to make the cutting system safe.
EU machinery legislation link
EN IEC 62841-4-3:2021/A12:2026 replaces Annex ZZ, which links clauses in the standard to essential requirements of Directive 2006/42/EC. When the standard is cited in the Official Journal of the European Union, the relevant clauses in Table ZZ.1 can give a presumption of conformity within the scope of the standard.
For manufacturers, that means the document is not only a test standard but also a conformity map for EU machinery safety.
What terms does EN IEC 62841-4-3:2021/A12:2026 define?
- Pedestrian controlled walk-behind lawnmower - a lawnmower intended to be guided by a person walking behind it.
- Cutting means - the part that performs the cutting action; in this amendment, replaceable cutting means are specifically marked.
- Integral battery - a battery built into the machine, covered by the battery isolation requirements in Annex K and Annex L.
- Isolation device - a device that disconnects battery energy from the serviceable region and prevents accidental reconnection.
- Operator presence control - the control that depends on operator action, but which is not sufficient on its own for battery isolation in the amended clauses.
- Guaranteed A-weighted sound power level (LWA) - the declared sound power value used as the guaranteed figure in the amended noise declaration.
Who uses EN IEC 62841-4-3:2021/A12:2026?
Manufacturers of pedestrian controlled walk-behind lawnmowers use EN IEC 62841-4-3:2021/A12:2026 when designing machines, choosing markings, and preparing instructions and declarations. Test laboratories use it for noise-related verification and for checking battery isolation and disconnection features.
Quality managers, compliance teams, importers and suppliers use it to build technical files and support EU machinery conformity work. It is also relevant to product safety assessors working in electric tools and horticultural equipment.
What changed in EN IEC 62841-4-3:2021/A12:2026 from the previous edition?
EN IEC 62841-4-3:2021/A12:2026 modifies EN IEC 62841-4-3:2021 and, together with EN IEC 62841-4-3:2021/prA1:2024, aligns the text with the published version of EN IEC 62841-4-7:2022.
The amendment:
- removes several notes from Clause 1, Clause 8, Clause 18, Clause 19, Clause 20 and Annex CC;
- adds and revises marking text in Clause 8;
- revises the noise declaration rule in Annex I;
- adds integral-battery isolation requirements in Annex K and Annex L;
- replaces Annex ZA and Annex ZZ.
Which standards are used with EN IEC 62841-4-3:2021/A12:2026?
EN IEC 62841-4-3:2021/A12:2026 uses the Annex ZA references below, together with EN IEC 62841-1:2015 as impacted by EN IEC 62841-1:2015/A11:2022.

What does the EN IEC 62841-4-3:2021/A12:2026 document contain?
EN IEC 62841-4-3:2021/A12:2026 contains replacement text for selected subclauses, not a full restatement of the product standard. The technical content is concentrated in Clause 8, Annex I, Annex K and Annex L, where marking, noise declaration and battery safety are updated.
It also contains Annex ZA and Annex ZZ tables that connect the standard to European references and to Directive 2006/42/EC. Those tables are the parts that compliance teams use when checking which clauses support which essential requirements.
The bibliography is updated as well, with several external references deleted.
