Corrosion Tester for Glazes and Engobes

 

 

 

 

 

 

 

 

based on ISO 28706-2 "Vitreous and porcelain enamels:

-

Determination of resistance to chemical corrosion by boiling acids

 

 

 

 

 

 

 

 

boiling neutral liquids and/or their vapours of corrosion protected flat surfaces (enameled, glazed, powder-coated

 

 

 

 

 

 

 

flat surfaces (enameled, glazed, powder-coated)

 

 

 

Apparatus allows to determine qualitative and quantitative the influence of corrosive liquids and their vapours

 

 

 

 

 

to metallic, silicatic and other corrosion protected surfaces by

 

 

 

 

 

 

 

 

 

 

 

 

•

loss in gloss

 

 

 

 

 

 

 

 

 

 

•

changing the structure of surface/defects

 

 

 

 

 

Example for corrosive changing of surface, simulated by the test:

Nachweis der Dauerhaftigkeit" (55. Würzburger Ziegellehrgang , Dezember2016)

 

 

 

 

 

Several producers of glazes and engobes are using this test for quality control.
