scope:
This part of ISO 3856 describes two methods for the determination of the lead content of the test solutions, prepared according to ISO 6713 or other suitable International Standards. The methods are applicable to paints havig "soluble" lead contents in the range of about 0,05 to 5 % (m/m). The flame atomic aborption spectrometric (AAS) method 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 dithizone spectrophotometric method should be used.
