ActivePaints and varnishes--Determination of “soluble” metal content--Part 4:Determination of cadmium content--Flame atomic absorption spectrometric method and polarographic method
色漆和清漆 “可溶性”金属含量的测定 第四部分:镉含量的测定 火焰原子吸收光谱法和极谱法
Application Summary AI generated
This standard specifies flame atomic absorption spectrometric and polarographic methods for determining the soluble cadmium content in paints and varnishes. It is applied in the coatings industry for quality control and safety testing, particularly to assess cadmium levels in liquid paint or dried film extracts that simulate potential leaching under acidic conditions. The standard ensures compliance with regulatory limits on toxic heavy metals in consumer and industrial coating products.
