Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 0562-1996 "export molybdenum powder lead and copper content by atomic absorption spectrometry method."
This standard compared with SN/T 0562-1996, the main technical changes are as follows.
--- The standard measurement method increases the concentration of the sample blank.
--- This standard modifies the standard name.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Hebei Exit Inspection and Quarantine.
The main drafters of this standard. Guo Lei, Chang Fang.
This standard replaces the standards previously issued as follows.
--- SN/T 0562-1996.
