PD CEN/TS 16731:2014 PDF

Scope: This Technical Specification describes a screening procedure for the determination of nitric-acid extractable inorganic arsenic in rice with hydride generation-AAS. The method has been developed and validated for the application of analysis in rice. It has been validated in an interlaboratory study according to ISO 5725 on parboiled rice and brown rice having an inorganic arsenic content of 0,092 mg/kg and 0,191 mg/kg.
