Rubber hoses and hose assemblies for use in oil burners - Specification (ISO 6806:1992)

Specifies the minimum requirements for two types of hose assembly: hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection, maximum working pressure 1,0 MPa (10 bar), maximum oil temperature 100 °C (type 1) and hose assemblies for insertion between the oil burner pump and the atomizing connection, working pressure 4,0 MPa (40 bar), maximum oil temperature 100 °C (type 2).

Gummischläuche und Schlauchleitungen für den Einsatz in Ölbrennern - Anforderung (ISO 6806:1992)

Diese Internationale Norm legt die Mindestanforderungen für Gummischläuche und -schlauchleitungen zum Einsatz in Ölbrennern fest. Es werden zwei Typen von Schlauchleitungen festgelegt: - Typ 1: Schlauchleitungen für Vor- und Rücklauf, jedoch nicht für den Einbau zwischen Ölbrennerpumpe und Düsenstock; maximaler Betriebsdruck 1,0 MPa (10 bar); maximale Öltemperatur 100 °C; - Typ 2: Schlauchleitungen für den Einbau zwischen Ölbrennerpumpe und Düsenstock; Betriebsdruck 4,0 MPa (40 bar); maximale Öltemperatur 100 °C.

Tuyaux et flexibles en caoutchouc pour brûleurs - Spécifications (ISO 6806:1992)

La présente Norme internationale fixe les prescriptions minimales pour les tuyaux et les flexibles en caoutchouc utilisés pour les brûleurs à fuel. Deux types de flexibles sont prescrits: -- Type 1: Flexibles pour le flux et le reflux mais non pour l'installation entre la pompe du brûleur et le système de pulvérisation; pression maximale de service 1,0 MPa (10 bar); température maximale du fuel 100 °C. -- Type 2: Flexibles pour insertion entre la pompe du brûleur et le système de pulvérisation; pression maximale de service 4,0 MPa (40 bar); température maximale du fuel 100 °C.
NOTE 1 Il convient de ne pas utiliser les flexibles prescrits dans la présente Norme internationale pour d'autres applications que les installations de brûleurs à fuel sans avoir fait l'objet d'essais particuliers.

IS0 6806:1992(E)
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO’ 6806 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products, Sub-Committee SC I, Noses
(rubber and plastics).
This second edition cancels and replaces the first edition
(IS0 6806:1984), clauses 1 and 2 , tables 3 and 4, sub-clause 6.2 and
annex C of which have been technically revised.
Annexes A, B, C and D form an integral part of this International Stan-
dard.
