GB 20814-2014 《Limit and determination of the quantity of heavy-metal elements in dye products》 Related products
This standard specifies the limit requirements and determination methods for 12 heavy metals in dyestuff products, which are applicable to various commodity dyestuff. By mixing acid to digest samples and using atomic absorption spectroscopy (AAS) to determine the content of heavy metals, dyestuff products meet environmental protection and safety standards. The standard provides an important basis for dyestuff production and quality control, aiming to reduce harmful heavy metals in dyestuff products, ensure consumer safety and environmental protection.
