This International Standard describes methods for the preparation of acid extracts required as the test solutions for the determination of the “soluble” metal contents of paints and related products in liquid or powder form.
The acid extracts are prepared in 0,07 mol/l hydrochloric acid, which is chosen as an approximation of the acid in the stomach. This International Standard is not applicable to dried or comminuted paint films (see ISO 6714).
WARNING — The procedures described in this International Standard are intricate and, therefore, should be carried out by those who are properly experienced in these analytical procedures. Adequate precision will only be obtained if all the details of the separation and extraction procedures are strictly observed.
For use in conjuction with Parts B6 to B12.
