European foreword
This document (EN 50632-1:2015) has been prepared by CLC/TC 116 “Safety of motor-operated
electric tools”.
The following dates are fixed:

(dop) 2016-08-03
• latest date by which this document has to be
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2017-08-03
conflicting with this document have to
be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This European Standard is divided into three parts:
Part 1: General requirements for the dust measurement which are common to electric motor-operated
tools (for the purpose of this standard referred to simply as tools);
Part 2 or 3: Requirements for the dust measurement for particular types of tools, which either
supplement or modify the requirements given in Part 1 to account for the particular characteristics of
these specific tools.
This Part 1 is to be used in conjunction with the appropriate Part 2 or 3 which contains clauses that
supplement or modify the corresponding clauses in Part 1 to provide the relevant requirements for
each type of product.
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.

Introduction
Inhalable dust emitted by electric motor-operated tools may present a hazard to the operator and
other exposed persons.
Therefore, this standard specifies a procedure how to measure the dust concentration produced by an
electric power tool under standardized conditions representing typical applications. However, the dust
concentration during actual use of the power tool may differ from the dust concentration measured in
accordance with this standard depending on the ways in which the tool is used.
The results of dust measurements can be used:
- for a declaration of the dust emission;
- for comparing the dust emission from tools of the same type;
- in a preliminary assessment of dust exposure at a workplace.
For all purposes, it is important to specify measurement procedures with known accuracy so that the
results of measurements taken by different laboratories can be compared.
The measurements of dust concentration are made in accordance with the standard EN 1093-9 for
the test room.

1 Scope
1.1 General
This European Standard specifies general requirements for the dust measurement of electric motor-
operated tools supplied from mains or from batteries. This European Standard applies to those tools
with and without dust extraction unit where dust such as mineral dust containing silica or wood dust
is expected.
1.2 Types of dust
Dust is a disperse distribution of solid substances in gases, particularly air, resulting from mechanical
processes. According to EN 481, two size categories are to be differentiated: the inhalable dust and
the respirable dust fraction. Inhalable dust refers to the entire inhalable fraction of the dust through
mouth and/or nose. Respirable dust relates to the fraction of the inhalable dust that can reach the
pulmonary alveoli due to its small particle size.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 481, Workplace atmospheres - Size fraction definitions for measurement of airborne particles
EN 1093-9, Safety of machinery – Evaluation of the emission of airborne hazardous substances –
Part 9: Pollutant concentration parameter, room method
EN 13205 (all parts), Workplace exposure – Assessment of sampler performance for measurement of
airborne particle concentrations
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
