Overview

EN 62841-4-2:2019/A11:2022 is a CLC/CENELEC amendment to the European safety standard for electric motor‑operated hand‑held tools, transportable tools and lawn and garden machinery - specifically Part 4‑2: Particular requirements for hedge trimmers. Approved 2022‑05‑30, this amendment (A11) clarifies scope and hazard coverage, updates mechanical‑safety requirements for handles and barriers, and revises normative references. It supports conformity with the EU Machinery Directive (2006/42/EC) and is intended for adoption as identical national standards.

Key topics and technical requirements

• Scope and hazard coverage: A11 explicitly states the document covers all significant hazards relevant to hedge trimmers and notes which essential requirements are not applicable (see NOTE Z101).
• Mechanical hazards - handle clearance: Revised Subclause 19.102.2.1 requires minimum distances of 120 mm from the nearest cutting edge to the rear side of handles (measured along the shortest path). For Category 1 tools the minimum distance from the front of the handle grip to the nearest blade tooth is 120 mm.
• Front hand barrier: Where a front hand barrier is fitted, distances are measured via the barrier edge, and the barrier must not have any openings with a minor dimension larger than 10 mm.
• Inspection and measurement: Compliance with the above is verified by inspection and measurement.
• Normative references: Annex ZA was replaced to add/update referenced IEC/ISO/EN documents (examples include IEC 60664‑3/4, IEC 61672‑1, ISO/IEC/EN acoustics and safety symbol standards).
• Noise & moisture clarifications: A11 follows A1 (earlier amendment) which introduced clarifications/corrections for moisture resistance and noise test code for hedge trimmers.
• Regulatory relationship: Annex ZZ maps normative clauses to essential requirements of Directive 2006/42/EC, supporting presumption of conformity when cited in the Official Journal.

Applications and who uses this standard

This standard is used by:

• Manufacturers and designers of electric and battery hedge trimmers to design safe products that meet European safety expectations.
• Test laboratories and conformity assessment bodies performing safety, mechanical‑clearance, noise and moisture resistance tests.
• Regulatory bodies and notified bodies assessing conformity with the Machinery Directive (2006/42/EC).
• Technical writers preparing safety instructions, markings and product documentation in line with the standard.

Practical applications include design validation for handle placement, front hand barrier geometry, test procedures for noise and moisture resistance, and preparing conformity documentation for CE marking.

Related standards

• EN 62841‑1 (general requirements for motor‑operated hand‑held tools)
• Normative references listed in Annex ZA: IEC 60664‑3/4, IEC 61672‑1, ISO 3744, ISO 22868, EN ISO 7010, ISO 11203, etc.
• EU Machinery Directive 2006/42/EC

1 Modification to Clause 1, “Scope”
Add the following to the existing Clause 1:
“This document covers all significant hazards, hazardous situations or hazardous events relevant for
machines covered by this document.
NOTE Z101 Essential requirements not mentioned in Table ZZ.1 are deemed to be not applicable, because the

Replace the existing Subclause 19.102.2.1 with the following:
“19.102.2.1  The front handle shall be located so that the distance from the nearest cutting edge of the
cutter blade to the rear side of any handle, except for Category 1, is not less than 120 mm as shown in
Figure 108 a) and Figure 108 b).
For Category 1, the shortest distance between the front of the handle grip and the nearest blade tooth
shall be at least 120 mm (see Figure 111). The distances shall be measured along the shortest path from
the front of the handle grip to the nearest cutting edge of the cutter blade.
For all categories in Table 101, if there is a front hand barrier, then the x and x distances in Figure 108 a)
1 2
and Figure 108 b) shall be measured along the shortest path from the backside of the handle, via the edge
of the front hand barrier, to the nearest cutting edge of the cutter blade. The front hand barrier shall not
have any openings with a minor dimension larger than 10 mm.
Compliance is checked by inspection and by measurement.”
