Electric motor-operated tools - Dust measurement Procedure - Part 1: General requirements

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 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.

Elektromotorna orodja - Postopek meritve prahu - 1. del: Splošne zahteve

Ta evropski standard določa splošne zahteve za meritve prahu elektromotornih orodij, ki se napajajo iz omrežja ali baterij. Ta evropski standard velja za tista orodja, pri katerih se pričakuje nabiranje prahu (na primer mineralnega prahu, ki vsebuje kremenico, ali lesnega prahu), ne glede na to, ali so opremljeni z enoto za izločevanje prahu ali ne.

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be withdrawn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.

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.
