Commercial dishwashing machines - Hygiene requirements and testing
This document specifies hygiene requirements for the operation of commercial dishwashing machines (hereinafter referred to as dishwashing machines) and the tests to be performed on these machines. It specifies requirements for reaching an appropriate hygienic status of articles treated in the dishwashing machines. This document also includes guidelines for the hygienic and proper operation, care and maintenance of dishwashing machines. Furthermore, methods for testing hygienic operation are defined.
This document applies to dishwashing machines used in a professional environment for cleaning wash ware that is used in contact with food, such as plates, crockery, glassware, cutlery, reusable boxes and similar articles.
Dishwashing machines are used in professional kitchens, e.g. in restaurants, canteens and hospitals and in businesses such as bakeries, butcher's shops, etc.
This document does not apply to domestic dishwashing machines, washer disinfectors for the treatment of medical devices and machines for industrial use.
Gewerbliche Spülmaschinen - Hygieneanforderungen und Prüfung
Dieses Dokument legt Hygieneanforderungen an das Betreiben von gewerblichen Spülmaschinen (nachfolgend als Spülmaschinen bezeichnet) und an die Prüfungen, die an diesen Maschinen durchzuführen sind, fest. Es legt Anforderungen zum Erreichen eines angemessenen hygienischen Zustands des in Spülmaschinen behandelten Spülguts fest. Dieses Dokument enthält auch einen Leitfaden für den hygienischen und ordnungsgemäßen Betrieb, die Pflege und Wartung von Spülmaschinen. Darüber hinaus werden Verfahren zum Prüfen eines hygienischen Betriebs festgelegt.
Dieses Dokument ist anwendbar für Spülmaschinen, die in gewerblicher Umgebung zum Reinigen von Spülgut eingesetzt werden, das in Kontakt mit Lebensmitteln verwendet wird, wie z. B. Teller, Geschirr, Glaswaren, Besteck, Mehrwegbehälter und ähnliche Artikel.
Spülmaschinen werden in gewerblichen Küchen, wie z. B. in Restaurants, Kantinen, Krankenhäusern, und in Unternehmen, wie z. B. in Bäckereien und Fleischereien, verwendet.

Des méthodes d’essai de fonctionnement hygiénique sont en outre définies.
Le présent document s’applique aux machines à laver la vaisselle utilisées dans un environnement professionnel, destinées à nettoyer les articles de vaisselle qui sont utilisés en contact avec les aliments, comme les assiettes, la vaisselle, la verrerie, les couverts, les boîtes réutilisables et les articles similaires.
Les machines à laver la vaisselle sont utilisées dans les cuisines professionnelles, par exemple dans les restaurants, les cantines et les hôpitaux, ainsi que dans les commerces, tels que les boulangeries, les boucheries, etc.
Le présent document ne s’applique pas aux lave-vaisselle domestiques, aux laveurs-désinfecteurs pour le traitement des dispositifs médicaux et aux machines à usage industriel.
Komercialni pomivalni stroji - Higienske zahteve in preskušanje
Ta dokument določa higienske zahteve v zvezi z delovanjem komercialnih pomivalnih strojev (v nadaljevanju: »pomivalni stroji«). Določa zahteve za higienske rezultate izdelkov, obdelanih v pomivalnem stroju. To vključuje tudi smernice za njihovo higiensko in pravilno delovanje ter nego in vzdrževanje. Opredeljene so tudi metode za preskušanje higienskega delovanja.
Pomivalni stroji se uporabljajo v profesionalnem okolju za čiščenje pribora, ki se uporablja v stiku z živili.
Ta dokument se uporablja za pomivalne stroje za čiščenje izdelkov, ki se uporabljajo v stiku z živili, kot so posoda, steklenina, jedilni pribor, škatle za večkratno uporabo in podobni izdelki.
Pomivalni stroji (glej točko 3.3) se na primer uporabljajo v kuhinjah restavracij, menz in bolnišnic ter v trgovskih podjetjih, kot so pekarne, mesnice itd.
Ta dokument se ne uporablja za gospodinjske pomivalne stroje, čistilno-dezinfekcijske naprave za obdelavo medicinskih pripomočkov in stroje za industrijsko uporabo (npr. stroje za čiščenje pladnjev za vzhajanje in povratnih steklenic, opremo drugih strojev, kot so mesoreznice, rezalniki, delilniki testa, gnetilniki ali mešalniki, ter vse druge vrste strojev, dele katerih bi bilo mogoče očistiti zunaj območja uporabe (WOP)).
