Vitreous and porcelain enamels - Method of test of self-cleaning properties (ISO 8291:1986)
Applies to enamelled walls of roasting devices, grills and baking devices; self-cleaning consists in the capacity first to absorb oil or fat in droplet form, and then to volatilize the greater part of the fat or oil by the sequential processes of distillation, decomposition, and combustion. Is not applicable to pyrolytically cleaning enamels.
Emaillierungen - Prüfung des Selbstreinigungsvermögens (ISO 8291:1986)
Émaux vitrifiés - Méthode d'essai des propriétés autonettoyantes (ISO 8291:1986)
La présente Norme internationale spécifie une méthode d'essai permettant de déterminer les propriétés des parois en émail vitrifié autonettoyant des rôtissoires, grils ou fours de cuisson, d'abord pour absorber les gouttelettes de corps gras, et ensuite pour en volatiliser la plus grande partie par un processus continu de distillation, de décomposition et de combustion (appelé dans la suite du texte «combustion» pour résumer). La présente Norme internationale n'est pas applicable aux émaux vitrifiés autonettoyants par pyrolyse.

Foreword
ISO (the International Organiration for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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 patt in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 8291 was prepared by Technical Committee ISO/TC 107,
