Paints and varnishes — Determination of total mercury — Flameless atomic absorption spectrometric me...
The reference method described is applicable to products having total mercury contents in the range of about 0.01 % (m/m) to 0.5 % (m/m). May also be extended to products with a total content of more than 0.5 % (m/m). The principle of the method consists in the combustion of the test portion with oxygen in an enclosed system. Reduction of the mercury(II) compounds contained in the resulting…

Paints and varnishes — Determination of "soluble" metal content — Part 2: Determination of...
The methods are applicable to coating materials having "soluble" antimony contents in the range of about 0,05 % (m/m) to 5 % (m/m). The AAS method should be used as the referee method in cases of dispute. The principle of the flame atomic absorption spectrometric method consists in aspiration of the test solution into acetylen/air flame. measurement of the absorption of the selected…

The principle consists in the aspiration of the test solution into a dinitrogen monoxide/acetylene flame. Measurement of the radiation emitted by barium at a wavelength of 553,5 nm. The ionization of barium atoms in the flame is suppressed by addition of potassium chloride. The method is applicable to coating materials having "soluble" barium contents in the range of about 0,05 % (m/m)…

The principle of the AAS method consists in inspiration of the test solution into an acetylen/air flame. Measurement of the absorption of the selected spectral line emitted by a cadmium hollow-cathode or cadmium discharge lamp, in the region of 228,8 nm. The principle of the polarographic method consists in electrolysis of the test solution in a polarographic cell measurement of the corresponding…

The principle consists in formation of a coloured complex from hexavalent chromium and diphenylcarbazide solution. After addition of orthophosphoric acid and sulfuric acid, spectralphotometric easurement of the colour at a wavelength in the region of 540 nm. The method is applicable to coating materials having hexavalent chromium contents in the range of about 0,05 % (m/m) to 5 % (m/m). This…
