DS/ISO 3856/2-1982 色漆和清漆.“可溶性”金属含量的测定.第2部分:锑含量的测定.火焰原子吸收光谱测定法和若丹明B (Rhodamine B) 分光光度法
Paints and varnishes. Determination of "soluble" metal content. Part 2: Determination of antimony content. Flame atomic absorption spectroscopic method and rhodamine B spectrophotometric method
This part of ISO 3856 specifies two methods for the determination of the antimony content of the test solutions prepared according to ISO 6713 or other suitable International Standards.1)
The methods are applicable to paints having "soluble" metal contents in the range of about 0,05 to 5 % (m/m).
The flame atomic absorption spectroscopic (AAS) method (clause 3) should be used as the reference method. Other methods can be used by agreement between the interested parties. If a photometric method is agreed, the Rhodamine B spectrophotometric method (clause 4) should be used. In case of dispute, the AAS method should be used.
