Vitreous and porcelain enamels - Determination of resistance to chemical corrosion - Part 2: Determination of resistance to chemical corrosion by boiling acids, boiling neutral liquids and/or their vapours (ISO 28706-2:2008)

ISO 28706-2:2008 describes a test method for the determination of the resistance of flat surfaces of vitreous and porcelain enamels to boiling acids, boiling neutral liquids and/or their vapours.
The method allows the determination of the resistance of vitreous and porcelain enamels to the liquid and vapour phases of the corrosive medium simultaneously.

Emails und Emaillierungen - Bestimmung der Beständigkeit gegen chemische Korrosion - Teil 2: Bestimmung der Beständigkeit gegen chemische Korrosion durch kochende Säuren, kochende neutrale Flüssigkeiten und/oder deren Dämpfe (ISO 28706-2:2008)

Dieser Teil von ISO 28706 legt ein Prüfverfahren zur Bestimmung der Beständigkeit von ebenen Email-
Oberflächen gegen kochende Säuren, neutrale Flüssigkeiten und/oder deren Dämpfe fest.
Dieses Verfahren erlaubt die gleichzeitige Bestimmung der Beständigkeit von Emails gegen die flüssige und
dampfförmige Phase des Korrosionsmittels.

Émaux vitrifiés - Détermination de la résistance à la corrosion chimique - Partie 2: Détermination de la résistance à la corrosion chimique par des acides bouillants ou des liquides neutres bouillants, et/ou leurs vapeurs (ISO 28706-2:2008)

L'ISO 28706-2:2008 spécifie une méthode d'essai permettant de déterminer la résistance de surfaces planes en émail vitrifié à des acides bouillants, des liquides neutres bouillants, et/ou leurs vapeurs.
La présente méthode permet de déterminer simultanément la résistance des émaux vitrifiés aux phases liquide et vapeur du milieu corrosif.

Steklasti in porcelanski emajli - Ugotavljanje odpornosti proti kemični koroziji - 2. del: Ugotavljanje odpornosti proti kemični koroziji s kislinami, ki vrejo, z nevtralnimi tekočinami in/ali njihovimi parami (ISO 28706-2:2008)

Ta del ISO 28706 opisuje preskusno metodo za ugotavljanje odpornosti ploščatih površin steklastih in porcelanskih emajlov proti kislinam, ki vrejo, proti nevtralnim tekočinam, ki vrejo, in/ali njihovim param. Ta metoda omogoča istočasno ugotavljanje odpornosti steklastih in porcelanskih emajlov proti tekočim in hlapnim fazam korozivnega medija.
