Overview

SIST EN IEC 62841-3-9:2020/A11:2020 is a European Standard amendment published by the CLC (European Committee for Electrotechnical Standardization) that specifies particular safety requirements for transportable mitre saws. This document amends and supplements EN IEC 62841-3-9:2020, focusing on electric motor-operated hand-held and transportable tools, including lawn and garden machinery, to ensure their safe design and use.

The amendment clarifies scope limits, enhances mechanical and noise safety requirements, and aligns the standard with EU machinery directives, providing manufacturers, safety professionals, and users with guidance on compliance and risk mitigation for transportable mitre saws.

This standard is an integral part of the EN IEC 62841 series, which addresses safety for various electric tools, and its compliance supports conformance with EU Directive 2006/42/EC on machinery safety.

Key Topics

• Scope and Applicability

  • Applies specifically to transportable mitre saws weighing up to 25 kg (single-person lift) or 50 kg (two-person lift).
  • Excludes stationary mitre saws, which are covered by EN 1870-3.

• Mechanical Safety Enhancements

  • Saw units must automatically return to a safe rest position after use.
  • Durability requirements for return devices, guards, and workpiece-activated sections have been reinforced.
  • Mechanical strength standards for plastic materials have been specified, including tensile and impact resistance properties.

• Saw Blade Specifications

  • Blades supplied with the tool intended for wood cutting must comply with EN 847-1:2017 to ensure safety and performance.
  • Verification through inspection and manufacturer documentation is mandated.

• Markings and Instructions

  • Updated requirements for safety markings, including noise emission information and warnings about sound exposure risks.
  • Instructions must clearly emphasize using only manufacturer-recommended saw blades conforming to relevant safety standards.

• Noise and Vibration Measurements

  • Normative reference to noise and vibration emission testing, with clarified measurement procedures and updated annex titles.

• European Union Directive Alignment

  • The standard supports compliance with essential health and safety requirements of Directive 2006/42/EC.
  • Annex ZZ details the relationship with EU machinery directives, specifying how the standard addresses various hazards including mechanical, electrical, ergonomic, and noise-related risks.

Applications

• Manufacturers of Transportable Mitre Saws

  • Use this standard as a mandatory benchmark to design safe and compliant mitre saws that meet European safety regulations.
  • Ensure mechanical robustness, safety guards, and control devices adhere to updated requirements.

European foreword
This document (EN IEC 62841-3-9:2020/A11:2020) was prepared by CLC/TC 116 "Safety of motor-
operated electric tools".
The following dates are fixed:

• latest date by which this document has (dop) 2021-04-20
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2024-04-20
standards conflicting with this document
have to be withdrawn
This document modifies by common modifications EN IEC 62841-3-9:2020, which consists of the text of
IEC 62841-3-9, Ed.2.0 prepared by IEC/TC 116 “Safety of motor-operated electric tools”.
This series is divided into four parts:
Part 1: General requirements which are common to most hand-held electric motor operated tools
(for the purpose of this standard referred to simply as tools) which could come within the
scope of this standard;
Part 2, 3 or 4: Requirements for particular types of tools which either supplement or modify the
requirements given in Part 1 to account for the particular hazards and characteristics of
these specific tools.
This Part 3-9 is to be used in conjunction with EN 62841-1:2015.
This Part 3-9 supplements or modifies the corresponding clauses in EN 62841-1:2015, so as to convert it
into the European Standard: Particular requirements for transportable mitre saws.
Where a particular subclause of Part 1 is not mentioned in this Part 3-9, that subclause applies as far as
relevant. When this standard states "addition", "modification" or "replacement", the relevant text in Part 1
is to be adapted accordingly.
The following print types are used:
- requirements; in roman type
- test specifications: in italic type;
- notes: in smaller roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes, tables and figures which are additional to those in Part 1 are numbered starting
from 101.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 62841-3-9:2020 are prefixed “Z”.
This European Standard follows the overall requirements of EN ISO 12100.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s), see informative Annex ZZ, which is an integral part of this
document.
Compliance with the clauses of Part 1 together with this Part 3-9 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
1 Modification to Clause 1, “Scope”
Add after the first paragraph:
“This document applies to transportable mitre saws having a mass of:
– maximum 25 kg for tools capable of being lifted by hand by one person;
– maximum 50 kg for tools capable of being lifted by hand by two persons.
This document does not apply to stationary mitre saws.
NOTE Z101 EN 1870-3 gives requirements for stationary mitre saws and mitre saws with a mass greater than indicated above.”

Add after the last paragraph:
“This document covers all significant hazards, hazardous situations or hazardous events relevant for
machines covered by this document.
NOTE Z102 Essential requirements not mentioned in Table ZZ.1 are deemed to be not applicable, because the corresponding
hazards are either not relevant for machines covered by this standard or do not require specific action by the designer.”

2 Modification to Clause 2, “Normative references”
Add the following normative reference:
EN 847-1:2017, Tools for woodworking - Safety requirements - Part 1: Milling tools, circular saw blades
3 Modification to Clause 8, “Marking and instructions”
Replace the last sentence in 8.3 with the following:
“This symbol needs not be in accordance with the colour requirements of ISO 3864-2:2016.”

Add the following new item to 8.14.2 a):
“Z101) Instruction to use only saw blades recommended by the manufacturer, which conform to
EN 847-1:2017, if intended for wood and analogous materials.”

Add the following after 8.14.2 c):
“8.14.2 Za) Replacement of items 3, 4 and 5 with the following:
3) The following information:
− that the declared noise emission value(s) have been measured in accordance with a
standard test method and may be used for comparing one tool with another;
− that the declared noise emission value(s) may also be used in a preliminary assessment of
exposure.
4) A warning:
− that the noise emissions during actual use of the power tool can differ from the declared
values depending on the ways in which the tool is used especially what kind of workpiece
is processed; and
− of the need to identify safety measures to protect the operator that are based on an
estimation of exposure in the actual conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is switched off and when it is running idle
in addition to the trigger time).”

4 Modification to Clause 19, “Mechanical hazards”
Replace the first paragraph of 19.102 with the following:
“When released, the saw unit shall automatically return to its rest position. The return device of the saw
unit, the lower guard and of the wo
