Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 573-2007 "tantalum powder."
Compared with this standard YS/T 573-2007, the main changes are as follows.
--- Remove tantalum powder grades FTA42, an increase of FTA150K, FTA170K, FTA200K, FTB85, FTB400 five products
Grade tantalum powder grades;
--- Products of the chemical composition, physical properties and electrical performance indicators have been adjusted;
--- FTC products increased hydrogen content requirements, in addition to outside FTC40 increased liquidity requirements.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points.
This standard was drafted. Ningxia Orient Tantalum Industry Co., Ltd., Zhuzhou Cemented Carbide Group Co., Ltd., China Nonferrous Metals Industry Standard
Associate Institute of Metrology and Quality.
