Ta evropski standard določa zahteve, ki zajemajo izdelavo in delovanje sestavnih delov sistemov za dovod in odvod zraka, vključno s tehnično varnostjo, ergonomičnostjo in higieničnostjo. Ta evropski standard se uporablja za prezračevalne sisteme v kuhinjah, povezane prostore in druge naprave za predelavo živil, namenjenih komercialni uporabi. Kuhinje in povezani prostori so posebni prostori, namenjeni za pripravo jedi, pranje in čiščenje jedilnega pribora in opreme ter shranjevanje hrane.  Ta evropski standard se ne uporablja za prezračevalne sisteme v hišnih gospodinjstvih. Podana je tudi metoda za preverjanje posamezne zahteve. Ta standard predpisuje zahteve, ki zajemajo izdelavo in delovanje, vključno s tehnično varnostjo, ergonomičnostjo in higieničnostjo ter preskušanjem. Če ni drugače določeno, se zahteve tega standarda preverjajo s pregledom in/ali meritvami.  OPOMBA   Upoštevajte morebitne dodatne ali alternativne nacionalne predpise o namestitvi, zahtevah glede aparatov ter o pregledu, vzdrževanju in obratovanju.
