This standard specifies methods for the determination of tin content in ferrotungsten using phenylfluorone spectrophotometry and Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP-AES). Applicable for the determination of tin content in 0.01% to 0.12%. Phenylfluorone spectrophotometry is used for the determination of lower content ranges, while ICP-AES is suitable for the determination of higher content ranges. The standard provides detailed operational steps and technical requirements for the accurate determination of tin content in ferrotungsten to ensure the accuracy and conformity of the measurement results.
