European foreword
This document (EN 50735-1:2024) has been prepared by CLC/TC 116 “Safety and environmental aspects of
motor-operated electric tools”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2025-07-01
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2027-07-01
conflicting with this document have to be
withdrawn
This document has been prepared in order to specify the requirements laid down in EN 45554:2020.
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.
Any feedback and questions on this document should be directed to the users’ national committee. A complete
listing of these bodies can be found on the CENELEC website.
1 Scope
This document provides product group specific guidance for a common understanding of measures, given by
any legislation, to define product specific information on the repairability and the reuse of used parts of motor-
operated hand-held tools, transportable tools, lawn and garden machinery. It is based on the following aspects:
— the inherent technical possibility/features to repair a product;
— the ability of the person repairing the product (skill level and tools);
— the possibility to reuse used parts of a product;
— the ability during repair for software updates.
The decision whether a product should be repaired is dependent on a range of factors such as health and
safety, intended use as well as economic, legal, and environmental aspects. However, the question of whether
it is reasonable to repair the product or reuse of used parts is outside of the scope of this document. This
document does not cover software (firmware and application software) or hardware modifications that change
the intended use of the product. Other risks making products non-compliant with safety standards are also
not covered by this document. The safety of the repairer during the repair is out of scope of this document.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
accidental breakdown
failure of a product by unintentional action, inadvertence, a mistake or a misuse by the user
3.2
commercially available tool
tool that is available for purchase
3.3
core product
part of parts of a product which expose(s) dangerous parts during disassembly
3.4
disassembly
process whereby a product is taken apart in such a way that it can subsequently be reassembled and made
operational
[SOURCE: EN 62542:2013, definition 6.1, modified by changing “an item” into “a product” and deleting the
note]
3.5
intended use
use of a product and parts in accordance with the information provided by the manufacturer
3.6
part
hardware, software (firmware and application software) constituent of a product
Note 1 to entry: A part can be an assembly of several parts.
3.7
product
good that is placed on the market and/or put into service and includes parts intended to be incorporated into it
Note 1 to entry: Products covered by this standard which are placed on the market and/or put into service as individual
parts for users and of which the environmental performance can be assessed independently.
3.8
reassembly
process by which a product, a spare part or a fastener is reassembled so as to fulfil its functional role and be
made operational
3.9
remote assistance
system that is intended to facilitate the search for information in the event of a breakdown, information how to
identify the origin of a breakdown, or information how to carry out the repair
Note 1 to entry: Remote assistance services include information (website, FAQs, etc.), remote diagnostic support (phone
call line, chat, application included in the equipment, interactive decision tree, etc.) and repair support (phone call line, video
call, remote control of the equipment, etc.).
3.10
repair
process of returning a faulty product to a condition where it can fulfil its intended use
Note 1 to entry: Repair does not include maintenance (operation to be carried out as described in the instruction manual).
3.11
reuse
operation by which a part extracted from a product at the end of its life is used in another product for the same
purpose for which it was intended
3.12
safety-critical spare part
spare part that fulfils a safety-critical function
Note 1 to entry: Potentially needs special attention, skills or testing during the assembly/disassembly.
3.13
spare part
separate part that can replace a part with the same function
3.14
special tool
tool that is generally only available to a manufacturer or a trained person
Note 1 to entry: Special measuring devices are included, i.e. devices for failure detection and testing after repair that can
only be handled by a trained person (level 2 professional repairer or a level 3 authorized professional repairer).
3.15
step
operation that finishes with a change of tool or with the removal and installation of a part when referring to
dismantling, disassembly, or reassembly
3.16
tool
physical object (hardware) or non-physical object (software) which supports the disassembly, reassembly,
repair or replacement process
4 Prerequisites for repair
4.1 General
The repairability of a product is conditioned by a number of prerequisites, which, often by law, shall be met in
advance of the repair process. The following list is a non-exhaustive overview over some of the general aspects
which shall be taken into consideration.
NOTE In order to determine a comparable index of repairability, it makes sense to distinguish between possible repairs
and those that are not permitted to be performed by the end user due to safety legislation.
4.2 Skill level required for repair
Repairs are distinguished according to their complexity level as follows:
Complexity level of the repair A: No tools are needed or only commercially available tools. No safety-critical
spare parts and no special tests or calibration needed when the repair is carried out in accordance with the
instruction manual. Opening of the core product is not necessary.
Complexity level of the repair B: Special tools, but no safety-critical spare parts and no calibration needed
when the repair is carried out in accordance with the repair manual. Opening of the core product might be
necessary.
Complexity level of the repair C: Special tools, safety-critical spare parts and, if necessary, calibration
needed when the repair is carried out in accordance with the repair manual. Opening of the core product
might be necessary.
Figure 1 shows a pictorial description of the complexity level of a repair.
Figure 1 — Flowchart of the complexity level of a repair
The skill levels of repairers are defined as follows:
Level 1 end user: person that can only perform the repair as described in the instruction manual.
NOTE For safety reasons, the repair of certain products or parts is not permitted to be performed by the end user,
including, without limitation, the following:
— reset an immobilizer system or security-related electronic modules;
— reprogram any electronic processing units or electric motor control units;
— change any equipment or electric motor
