StandardDetails

This part of ISO 3856 describes two methods for the determination of the antimony content of the test solutions prepared according to ISO 6713 or other suitable International Standards. The methods are applicable to paints having "soluble" antimony contents in the range of about 0,05 to 5 % (m/m). The flame atomic absorption spectrometric (AAS) method (clause 3) should be used as the referee method in cases of dispute. Other methods can be used by agreement between the interested parties. If a spectrophotometric method is agreed, the Rhodamine B spectrophotometric method (clause 4) should be used.
