The Spectrophotometric Determination of Silicon in Steels.

摘要

The report summarizes the results of an investigation,by a Working Party of the BSC/BISPA Chemical Analysis Committee,comparing the performance of two ISO spectrophotometric methods for the determination of silicon in steels. The work is part of the United Kingdom's contribution to that of ISO/TC17/SC1. The finally approved ISO method is now recommended for use in the UK for the determination of silicon in steel in the low range (0.002-0.10%). Further work in adapting the ISO method for general range application has resulted in a modified procedure,which is recommended as a British Standard method for use as an alternative to the British Standard gravimetric method.
