GB/T 8704.1-1997 Methods for chemical analysis of ferrovandium. The infrared absorption method and the gasometric method for the determination of carbon content (English Version)
This standard applies to the determination of carbon content in ferrovanadium. This standard specifies the following two methods for the determination of carbon content in ferrovanadium. Method I: infrared absorption method, measuring range: 0.025% to 1.200%. Method Ⅱ: gas volumetric method, measuring range: 0.400% to 1.200%.
