Scope

This part of ISO 3856 specifies two methods for the determination of the lead content of the test solutions, prepared according to ISO 6713 or other suitable International Standards1). 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 Iclause 3) should be used as the reference method. Other methods can be used by agreement between the interested parties. If a spectrophotometric method is agreed, the dithizone method (clause 4) should be used. In case of dispute, the AAS method should be used.
