Paints and varnishes. Determination of solvents in water-thinnable coating materials. Gas-chromatographic method
| Published By | Publication Date | Number of Pages |
| BSI | 2019 | 18 |
This document specifies a method for the gas-chromatographic determination of the solvents in water-thinnable paints and varnishes, binder solutions, emulsions and dispersions.
With the precision stated in Clause 13, single components above 0,02 % (mass fraction) can be determined quantitatively.
The method defined in this document is not applicable for the determination of Volatile Organic Compounds (VOC) and Semi-Volatile Organic Compounds (SVOC) content.
NOTE
For the determination of VOC and SVOC, see ISO 11890-2 [ 2 ].
