Stainless steel shell boilers
This European Standard specifies requirements for electrically heated shell boilers manufactured from stainless steel specifically dedicated for generating steam for sterilizers.
This European Standard covers only boilers that are heated by immersion heaters and which have a maximum allowable pressure (PS) of 6 bar, a maximum volume (V) of 1 000 litres and a product of PS x V not greater than 3 000 bar x l.
Edelstahl-Großwasserraumkessel
Diese Norm legt die Anforderungen an elektrisch beheizte Großwasserraumkessel aus nichtrostenden Stählen (Edelstahl) fest, die zur Versorgung von Sterilisations- und Desinfektionsanlagen dienen.
Diese Norm gilt nur für tauchsiederbeheizte Dampferzeuger, mit einem maximal zulässigen Druck von 6 bar, einem maximalen Volumen von 1 000 l und einem Druck-Liter-Produkt von nicht mehr als 3 000 bar x Liter.
Chaudieres a tubes de fumée en acier inoxydable
présente Norme européenne prescrit les exigences applicables aux chaudieres a tubes de fumée chauffées électriquement, fabriquées en acier inoxydable spécifiquement destinées a la production de vapeur pour stérilisateurs et dispositifs de désinfection.
Seules les chaudieres, qui sont chauffées par des dispositifs de chauffe immergés et qui ont une pression maximale admissible (PS) égale a 6 bar, un volume maximal (V) de 1 000 l et un produit PS x V inférieur ou égal a 3 000 bar x l, sont couverts par la présente Norme européenne.
