This standard was last reviewed and confirmed in 2012. Therefore this version remains current.
Specifies a method for determining titanium dioxide content in all kinds of paper and board, in particular coated or filled products.

The limits of determination depend on the amount of sample taken. Titanium present in other forms will not interfere in the determination.
