Paper and board — Determination of titanium dioxide content

Specifies a method for determining titanium dioxide content in all kinds of paper and board, in particular coated or filled products. It comprises two procedures for the final determination of titanium based on spectrophotometry and flame atomic absorption spectrophotometry, respectively. The limits of determination depend on the amount of sample taken. Titanium present in other forms will not interfere in the determination.
