Safety of machinery - Evaluation of the emission of airbone hazardous substances - Part 11: Decontamination index
This standard describes a method for the measurement of the decontamination index of pollution control systems (capture devices or other control methods, and when appropriate, separation equipment) installed on a machine. This method uses the real pollutant and may be operated in room or field environments. It should be observed that this method is not applicable if the expected concentrations, especially during the shutdown or the removal of the pollution control system, are liable to incur a risk to the health of the operators or other occupants present.
Sicherheit von Maschinen - Bewertung der Emission von luftgetragenen Gefahrstoffen - Teil 11: Reinigungsindex
Anwendungsbereich
Diese Norm beschreibt ein Verfahren zur Messung des Reinigungsindexes von Luftreinigungssystemen (z. B.
Absaugeinrichtungen einschließlich örtlicher Absaugung, Wasserbedüsungssystem und, falls zutreffend,
Abscheidevorrichtungen, die mit einer Maschine verbunden sind. Dieses Verfahren verwendet den realen
luftverunreinigenden Stoff (siehe 4.2 von E N1093-1:1998 ?Sicherheit von Maschinen - Bewertung der Emission
luftgetragener Gefahrstoffe von Maschinen - Teil 1: Auswahl der Prüfverfahren") und kann im Prüfraum oder im
Feld angewendet werden.
Es sollte beachtet werden, dass während der Prüfung, besonders beim abgestellten oder entfernten Luftreini-gungssystem,
die Konzentration an Gefahrstoffen, sofern vorhanden, so ansteigen kann, dass sie eine
Gesundheitsgefahr für das Bedienungspersonal oder andere im Raum Anwesende sein kann.
WARNUNG Diese Norm behandelt nicht die Schutzmaßnahmen, die zur Abwendung dieses Risikos notwendig sind.
Die Messung des Reinigungsindexes eines Luftreinigungssystems kann dienen:
- zur Bewertung der Leistungsfähigkeit des Luftreinigungssystems einer Maschine;
- zur Bewertung von Verbesserungsmaßnahmen an einem Luftreinigungssystem;
- zum Vergleich von Luftreinigungssystemen für Maschinen gleichartiger Konstruktion;
- zum Einordnen von Luftreinigungssystemen entsprechend ihrer Reinigungswirksamkeit;
- im Fall von Absaugeinrichtungen, zum Bestimmen des Luftvolumenstroms, der notwendig ist, um einen
bestimmten Reinigungsgrad zu erreichen;
- zum Bestimmen des Standes der Technik von Luftreinigungssystemen für Maschinen in Bezug auf die
Reinigungswirksamkeit.
Sécurité des machines - Evaluation de l'émission de substances dangereuses par l'air - Partie 11: Indice d'assainissement
Cette norme décrit une méthode de mesurage de l'indice d'assainissement des systemes de maîtrise de la pollution tels que dispositifs de captage incluant les extractions locales, les systemes a pulvérisation d'eau, et lorsque cela convient, équipement(s) de séparation montés sur une machine. Cette méthode utilise le polluant réel (voir 4.2 de l'EN 1093-1:1998 « Sécurité des machines - Evaluation de l'émission de substances dangereuses véhiculées par l'air - Partie 1 : Choix des méthodes d'essai ») et peut etre utilisée en salle d'essai ou in situ.
Il convient de noter qu'au cours de l'essai, particulierement pendant l'arret ou la suppression du systeme de maîtrise de la pollution, les concentrations en substances dangereuses éventuellement présentes, peuvent atteindre des niveaux susceptibles de provoquer des risques pour la santé des opérateurs ou autres occupants présents dans le local.
AVERTISSEMENT La présente Norme ne traite pas des moyens de protection requis pour maîtriser ces risques.
Le mesurage de l'indice d'assainissement du systeme de maîtrise de la pollution permet :
- l'évaluation des performances d'un systeme de maîtrise de la pollution d'une machine ;
- l'évaluation des améliorations apportées a un systeme de maîtrise de la pollution ;
- la comparaison des systemes de maîtrise de la pollution équipant des machines de conception similaire ;
- le classement des systemes de maîtrise de la pollution suivant leur efficacité d'assainissement ;
- dans le cas d'un systeme d'aspiration, la détermination du débit d'air pour atteindre un niveau donné ;
- la détermination de l'état actuel de la technique des systemes de maîtrise de la pollution équipant les machines pour ce qui concerne l'efficacité d'assainissement.

Page 4EN 1093-11:2001IntroductionThis is a type B standard as specified in EN 1070. This standard is a part of EN 1093. Part 1 “ Safety of machinery- Evaluation of the emission of airborne hazardous substances - Part 1: Selection of test methods” of this standardpresents a selection of different methods for the evaluation of the emission of airborne hazardous substances frommachines.1 ScopeThis standard describes a method for the measurement of the decontamination index of pollution control systemse. g. capture devices including local exhaust ventilation, water spray systems and, when appropriate, separationequipment installed on a machine. This method uses the real pollutant (see 4.2 of EN 1093-1 : 1998 “ Safety ofmachinery — Evaluation of the emission of airborne
hazardous substances — Part 1: Selection of test methods”)and can be operated in room or field environments.It should be observed that during the test, especially during the shutdown or the removal of the pollution controlsystem, the concentration of hazardous substances , if present, can reach levels which are liable to incur a risk tothe health of the operators or other occupants present in the room.Warning: This standard does not deal with the protective measures required to control these risks.Measurement of the decontamination index of pollution control system can serve for the:– evaluation of the performance of a pollution control system of a machine;– evaluation of the improvement of a pollution control system;– comparison of pollution control systems for machines of similar design;– ranking of pollution control systems according to their decontamination efficiency;– determination of the air flow rate in the case of an exhaust system to achieve a given level;– determination of the state of the art of pollution control systems for machines with respect to the decontamina-tion efficiency.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
