Prezračevanje stavb - Klimatske naprave - Ocenjevanje in lastnosti naprav, sestavnih delov in sekcij/sklopov

Ta evropski standard določa zahteve in preskuse za ocenjevanje ter lastnosti klimatske naprave kot celote. Prav tako določa zahteve, priporočila, razvrstitev ter preskušanje določenih sestavnih delov in sklopov klimatskih naprav. Pri številnih sestavnih delih in sklopih se navezuje na standarde sestavnih delov, vendar določa tudi omejitve ali uporabo standardov, pripravljenih za samostojne sestavne dele.
Standard se uporablja tako za standardizirane modele, ki so različno veliki, a imajo skupno konstrukcijsko zasnovo, kot tudi za enote, načrtovane po meri. Uporablja se za predizdelane klimatske naprave in tudi za enote, ki so izdelane in vgrajene na izbrani lokaciji. Enote s področja uporabe tega standarda na splošno vključujejo vsaj ventilator, izmenjevalec toplote in zračni filter. Ta standard se ne uporablja za:
a) klimatske naprave, namenjene omejenemu prostoru stavbe, na primer enote ventilatorskih tuljav;
b) enote za stanovanjske stavbe;
c) enote, ki prezračujejo prostor predvsem za namene proizvodnega procesa.
