Fume cupboards - Part 7: Fume cupboards for high heat and acidic load

This document applies for
- fume cupboards for high heat load
- fume cupboards for handling of perchloric acid
- fume cupboards for handling of hydrofluoric acid
- fume cupboards for high heat load in combination with acidic digestions.
This document applies in conjunction with EN 14175-1 to EN 14175-4 and, where appropriate, to EN 14175-6 and specifies supplementary information relevant to vocabulary, safety and performance requirements, type test methods, on-site test methods and marking of the listed special purpose fume cupboards.
NOTE   EN 14175-6 applies for variable air volume fume cupboards. Experience shows that fume cupboards for high heat  load offer much safer working conditions when operated with fixed air volume flow.
This document does not apply for microbiological safety cabinets, recirculatory filtration fume cupboards and fume cupboards for carrying out work on radioactive materials.

Abzüge - Teil 7: Abzüge für hohe thermische und Säurelasten (Abrauchabzüge)

Dieses Dokument gilt für
-   Abzüge für hohe thermische Lasten,
-   Abzüge für hohe thermische Lasten in Verbindung mit Säureaufschlüssen,
-   Perchlorsäureabzüge,
-   Flusssäureabzüge.
Dieses Dokument gilt in Verbindung mit EN 14175-1 bis EN 14175-4 und gegebenenfalls mit EN 14175-6; es legt zusätzliche Angaben zu den oben aufgeführten Sonderabzügen fest, die sich auf Begriffe, Sicherheits- und Leistungsanforderungen, Baumuster- und vor-Ort-Prüfverfahren und die Kennzeichnung beziehen.
ANMERKUNG      EN 14175-6 gilt für Abzüge mit variablem Luftstrom. Die Erfahrung hat gezeigt, dass Abzüge für hohe thermische Lasten viel sicherere Arbeitsbedingungen bieten, wenn sie mit festem Luftvolumenstrom betrieben werden.
Dieses Dokument gilt nicht für mikrobiologische Sicherheitswerkbänke, Absaugboxen mit Luftrückführung und Radionuklidabzüge.

Sorbonnes - Partie 7: Sorbonnes pour charge thermique et acide élevée

Le présent document s’applique :
-   aux sorbonnes conçues pour une charge thermique élevée ;
-   aux sorbonnes conçues pour une charge thermique élevée associée à la minéralisation chimique ;
-   aux sorbonnes destinées à la manipulation d’acide perchlorique ;
-   aux sorbonnes destinées à la manipulation d’acide fluorhydrique.
Le présent document s’applique conjointement avec les normes EN 14175-1 à EN 14175-4 et, le cas échéant, l’EN 14175-6, et spécifie des informations supplémentaires concernant le vocabulaire, les exigences de sécurité et de performance, les méthodes d’essai de type, les méthodes d’essai sur site et le marquage des sorbonnes à usage spécifique énumérées ci-dessus.
NOTE   L’EN 14175-6 s’applique aux sorbonnes à débit d’air variable. L’expérience montre que les sorbonnes conçues pour une charge thermique élevée offrent des conditions de travail beaucoup plus sûres lorsqu’elles sont utilisées avec un débit d’air fixe.
Le présent document ne s’applique pas aux postes de sécurité microbiologiques, aux sorbonnes à recirculation et aux sorbonnes pour la réalisation des travaux sur des matériaux radioactifs.

Part 5 (Recommendations for installation and maintenance) has been published as Technical Specification CEN/TS 14175-5. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 14175-7:2012 (E) 4 Introduction The objective of this document is to consider fume cupboards classified for special applications involving high heat load and/or strong acidic load requiring additional construction, safety, operating and maintenance features to those identified in EN 14175-1 to EN 14175-6. The use of these special application fume cupboards instead of general purpose fume cupboards is usually the result of a risk assessment. 1 Scope This European Standard applies for  fume cupboards for high heat load;  fume cupboards for high heat load in combination with acidic digestions;  fume cupboards for handling of perchloric acid;  fume cupboards for handling of hydrofluoric acid. This European Standard applies in conjunction with EN 14175-1 to EN 14175-4 and, where appropriate, to EN 14175-6 and specifies supplementary information relevant to vocabulary, safety and performance requirements, type test methods, on-site test methods and marking of the listed special purpose fume cupboards. NOTE EN 14175-6 applies for variable air volume fume cupboards. Experience shows that fume cupboards for high heat

load offer much safer working conditions when operated with fixed air volume flow. This European Standard does not apply for microbiological safety cabinets, recirculatory filtration fume cupboards and fume cupboards for carrying out work on radioactive materials. 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.
