GB/T 9758.7-1988 《Paints and varnishes--Determination of “soluble” metal content--Part 7:Determination of mercury content of the pigment portion of the paint and of the liquid portion of water-dilutable paints--Flameless atomic absorption spectrometric method》 Related products

GB/T 9758.7-1988 is a Chinese national standard that specifies a method for the determination of "soluble" mercury in Paints and varnishes by flameless atomic absorption spectroscopy (AAS). The standard applies to Paints with a mercury content of 0.005% to 0.05% (mass ratio), and specifically states that the determination method involving the liquid part of water-dilute Paints is only applicable to water-dilute paints. The standard provides specifications for the accurate determination of mercury content in the Coatings industry, which is of great significance for environment protection and human health.
