Electric motor-operated electric tools - Dust measurement procedure - Part 2-3: Particular requirements for concrete grinders and disk-type sanders

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.
This part of EN 50632 applies to concrete grinders and disc-type sanders.

Outils électriques à moteur - Procédure de mesure de la poussière - Partie 2-3: Exigences particulières pour les rectifieuses à béton et les ponceuses à disque

La présente partie de l’EN 50632 s’applique aux rectifieuses à béton et aux ponceuses à disque.

Elektromotorna orodja - Postopek merjenja prahu - 2-3. del: Posebne zahteve za brusilnike betona in diskovne brusilnike

Ta evropski standard določa splošne zahteve za merjenje prahu elektromotornih orodij, ki se napajajo prek omrežja ali baterij. Ta standard se uporablja za orodja, pri katerih se pričakuje nabiranje prahu (na primer mineralnega prahu, ki vsebuje kremenico, ali lesnega prahu), ne glede na to, ali so opremljena z enoto za izločevanje prahu.
1.2 Vrste prahu
Prah je razpršena porazdelitev trdnih snovi v plinih, zlasti v zraku, do katere pride pri mehanskih postopkih. V skladu s standardom EN 481 se razlikuje med dvema kategorijama velikosti: vdihljivi in respiratorni delež prahu. Vdihljivi prah se nanaša na celoten vdihljivi delež prahu skozi usta in/ali nos. Respiratorni prah se nanaša na delež vdihljivega prahu, ki lahko zaradi majhne velikosti delcev doseže pljučne mešičke.
Ta del standarda EN 50632 se uporablja za brusilnike betona in diskaste brusilnike.

This European Standard was approved by CENELEC on 2016-05-03. CENELEC members are bound to comply with the CEN/CENELEC

Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC

Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation

under the responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the

same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic,

Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

European foreword

This document (EN 50632-2-3:2016) has been prepared by CLC/TC 116 “Safety of motor-operated

electric tools”.
The following dates are fixed:
(dop) 2017-05-03
• 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 (dow) 2018-05-03
standards 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 2 is to be used in conjunction with EN 50632-1:2015.

This Part 2 supplements or modifies the corresponding clauses in EN 50632-1:2015.

This Part 2 was developed to set out requirements for the measurement of the concentration for

inhalable and respirable dust emitted by concrete grinders or disc-type sanders.

Where a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies as far as

reasonable. When this standard states "addition", "modification" or "replacement", the relevant text in

Part 1 is to be adapted accordingly.

Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101.

This European Standard has been drafted in accordance with the CEN/CENELEC Internal

Regulations, Part 3.
The following print types are used:
- requirements proper: in roman type;
- test specifications: in italic type;
- explanatory matter: in smaller roman type.
The terms defined in Clause 3 are printed in bold typeface.
