标准摘要
ISO 15647:2004 specifies a method of isotopic analysis of uranium hexafluoride (UF 6 ) with 235 U concentrations less than or equal to 5 % by mass and 234 U and 236 U concentration between 0,001 % by mass and 1,5 % by mass. The method is in routine use to determine conformance to UF 6 specifications. ISO 15647:2004 is applicable if the mass spectrometer uses Faraday cups.
