YB/T 4739-2019 《Ferrochromium.Determination of phosphorus, aluminium, titanium, copper, manganese, calcium content.The inductively coupled plasma-atomic emission spectrometric method》 Related products

This standard specifies the method for the determination of phosphorus, aluminum, titanium, copper, manganese and calcium content by Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP-AES). It is suitable for the determination of elements in ferrochromium with a carbon content of less than 4%. At the same time, the determination of corresponding elements in silicon-chromium alloys can also be carried out by reference. A number of normative documents are quoted, and the principle of sample analysis and the requirements for the use of reagents are described. Users are warned that they need to have laboratory work experience, be responsible for taking appropriate safety and health measures, and comply with national regulations.
