EN 1093-11:2001+A1:2008

Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 11: Decontamination index

This standard describes a method for the measurement of the decontami¬nation index of pollution con¬trol systems e. g. capture devices including local exhaust ventilation, water spray systems and, when appropriate, separation equipment installed on a machine. This method uses the real pollutant (see 4.2 of EN 1093-1 : 1998 “ Safety of machinery — 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 control system, the concentration of hazardous substances , if present, can reach levels which are liable to incur a risk to the 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.

Sicherheit von Maschinen - Bewertung der Emission von luftgetragenen Gefahrstoffen - Teil 11: Reinigungsindex

Sécurité des machines - Évaluation de l'émission de substances dangereuses véhiculées par l'air - Partie 11 : Indice d'assainissement

Cette norme décrit une méthode de mesurage de l'indice d'assainissement des systèmes de maîtrise de la pollution
tels que dispositifs de captage incluant les extractions locales, les systèmes à 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 — Évaluation de l'émission de substances dangereuses véhiculées
par l'air — Partie 1 : Choix des méthodes d'essai») et peut être utilisée en salle d'essai ou in situ.
Il convient de noter qu’au cours de l’essai, particulièrement pendant l'arrêt ou la suppression du système 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 système de maîtrise de la pollution permet :
— l'évaluation des performances d'un système de maîtrise de la pollution d'une machine ;
— l'évaluation des améliorations apportées à un système de maîtrise de la pollution ;
— la comparaison des systèmes de maîtrise de la pollution équipant des machines de conception similaire ;
— le classement des systèmes de maîtrise de la pollution suivant leur efficacité d'assainissement ;
— dans le cas d'un système d'aspiration, la détermination du débit d'air pour atteindre un niveau donné ;
— la détermination de l'état actuel de la technique des systèmes de maîtrise de la pollution équipant les machines
pour ce qui concerne l'efficacité d'assainissement.
