European foreword

This document (EN IEC 62841-2-3:2021/A11:2021) 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 (dop) 2022-05-03
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2025-05-03
standards conflicting with this document
have to be withdrawn

This document modifies by common modifications EN IEC 62841-2-3:2021, which consists of the text of

116/444/FDIS (future IEC 62841-2-3, Ed 1) prepared by IEC/TC 116 “Safety of motor-operated electric

tools”.

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 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.

The Part 2-3 is to be used in conjunction with EN 62841-1:2015 and its amendments.

The Part 2-3 supplements or modifies the corresponding clauses in EN 62841-1:2015, so as to convert it

into the European Standard: Particular requirements for hand-held grinders, disc-type polishers and disc-

type sanders.

Where a particular subclause of Part 1 is not mentioned in Part 2-3, 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 62841-2-3:2020 are prefixed “Z”.
This document 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 Part 2-3 provides one means of conforming with the

essential health and safety requirements of the Directive concerned.

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 tools

covered by this standard.

NOTE Z101 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 references:

“ISO 603-14:1999, Bonded abrasive products — Dimensions — Part 14: Grinding wheels for deburring and

fettling/snagging on an angle grinder

ISO 603-16:1999, Bonded abrasive products — Dimensions — Part 16: Grinding wheels for cutting-off on

hand-held power tools”
3 Modification to Clause 8, “Marking and instructions”
Add the following to 8.14.2 Za):

“6) A warning that grinding thin sheets of metal or other easily vibrating structures with a large surface

can result in a total noise emission much higher (up to 15 dB) than the declared noise emission

values. Such workpieces should as far as possible be prevented from emitting sound by suitable

measures such as the application of heavy flexible damping mats. The increased noise emission

is also to be considered for both the risk assessment of noise exposure and selecting adequate

hearing protection.”
4 Modification to Clause 19, “Mechanical hazards”
Replace the existing 19.104.2 with the following:

“19.104.2 The flange diameter for wheel Type 1 that are thicker than 5 mm shall be:

D ≥ 0,33D

The flange diameter for wheel Type 1 that are 5 mm and thinner and wheel Types 6, 11, 27, 28, 29, 41

and 42 shall be:
D = (20 ± 1) mm for 55 mm ≤ D < 80 mm
for 80 mm ≤ D ≤ 105 mm for wheels with a bore diameter of 10 mm (3/8 inch
D = (20 ± 1) mm
UNC)
for 80 mm ≤ D ≤ 105 mm for wheels with a bore diameter of 16 mm (5/8 inch
D = (29 ± 1) mm
UNC)
= (41 ± 1) mm for 105 mm < D ≤ 230 mm

For wheel Type 41 and diamond wheels, the D dimension may exceed the above values for inner

flanges and outer flanges. For all other wheel types, the diameter D may exceed the above values for

inner flanges only.

For wheel Types 27, 28 and 42: The outer dimensions of the outer flange shall be limited so that there is

no interference with the depressed centre of wheels in accordance with ISO 603-14:1999 and

ISO 603-16:1999 as illustrated in Figure Z101 with the dimensions ØK, R and F as specified in Table Z101.

5 Modification to Clause 21, “Construction”
Replace the existing subclause 21.35 with the following:
“21.35 Modification:
This subclause is applicable only for

— disc-type sanders used exclusively for sanding wooden floors in accordance with 8.14.2 b) 107); and

— grinders intended to be used with a wheel guard of Type E or Type F in accordance with

8.14.2 a) 101) and 8.14.2 b) 108).”
6 Modifications to Annex I, “Measurement of noise and vibration emissions”
Replace the title of Annex I with the following:
“Annex I

Measurement of noise and vibration emissions”
and delete the NOTE.

EN IEC 62841-2-3:2021/A11:2021 (E)

Replace the first paragraph and NOTE 1 of the existing subclause I.2.3.1 with the following:

“The A-weighted emission sound pressure level at the work station, L , shall be determined in accordance

with EN ISO 11203:2009 as follows:
L = L - Q
pA WA
where Q = 8 dB.”

NOTE 1 This value of Q has been determined, during experimental investigations, to be applicable to hand-held

power tools. The resulting A-weighted emission sound pressure level at the workstation is equivalent to the value of

the surface sound pressure level at a distance of 0,7 m from the power tool. This distance has been chosen to give

satisfactory reproducibility of results, and to permit comparison of the acoustic performance of different hand-held

power tools, which do not, in general, have uniquely defined work stations. Under free field conditions, where it could

be required to estimate the emission sound pressure level, L , at a distance r in m from the geometric centre of

pA,r1 1
the power tool, this can be done by applying the formula:
0,7
L = L + 20 lg dB
pA,r1 pA
Replace the existing subclause I.2.4 with the following:

"I.2.4 Installation and mounting conditions of the power tools during noise tests

Addition:

Angle grinders are suspended and fitted with an artificial wheel equivalent to the rated capacity as

specified in Figure I.104 and Table I.102 for the application “grinding”. Straight grinders are suspended

and fitted with an artificial wheel equivalent to the rated capacity as specified in Figure I.106 and

Table I.105. Disc-type polishers are suspended and fitted with a lambswool polishing pad of rated

capacity. Disc-type sanders are suspended and fitted with a sanding disc of rated capacity. For angle
