Vitreous and porcelain enamels - Determination of resistance to chemical corrosion - Part 2: Determination of resistance to chemical corrosion by boiling acids, boiling neutral liquids, alkaline liquids and/or their vapours (ISO 28706-2:2017)

ISO 28706-2:2017 specifies a test method for the determination of the resistance of flat surfaces of vitreous and porcelain enamels to boiling acids, boiling neutral liquids, alkaline liquids and/or their vapours.
This 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, alkalische Flüssigkeiten und/oder deren Dämpfe (ISO 28706-2:2017)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Beständigkeit von ebenen Email-Oberflächen gegen kochende Säuren, kochende neutrale Flüssigkeiten, alkalische Flüssigkeiten und/oder deren Dämpfe fest.
Dieses Verfahren erlaubt die gleichzeitige Bestimmung der Beständigkeit von Emails und Emaillierungen 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, des liquides neutres bouillants, ou des liquides alcalins et/ou leurs vapeurs (ISO 28706-2:2017)

ISO 28706-2:2017 spécifie une méthode d'essai permettant de déterminer la résistance de surfaces planes en émail vitrifié à des acides bouillants, des liquides neutres bouillants, des liquides alcalins 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 in nevtralnimi tekočinami, ki vrejo, bazami in/ali njihovimi parami (ISO 28706-2:2017)

Ta dokument določa preskusno metodo za ugotavljanje odpornosti ravnih površin steklastih in porcelanskih emajlov proti kemični koroziji s kislinami ter nevtralnimi tekočinami, ki vrejo, bazami in/ali njihovimi parami.
Ta metoda omogoča ugotavljanje odpornosti steklastih in porcelanskih emajlov proti tekočem in plinastem stanju korozivnega medija.
