ISO 3856-4-1984 《Paints and varnishes - Determination of "soluble" metal content - Part 4: Determination of cadmium content - Flame atomic absorption spectroscopy (AAS) and Polarography》 Related products

This standard specifies two methods for the determination of cadmium content in Paints, including flame atomic absorption spectroscopy (AAS) method (AAS) and Polarography. Applies to Coatings with "soluble" cadmium content in the range of 0.05% to 5% (m/m). The standard describes how to prepare the test solution and states that the AAS method should be used as a referee method in cases of dispute. Polarography is also recognized as an alternative method. The standard ensures the accuracy of cadmium content determination, meeting Coating mass and safety requirements.
