ASTM D4922-94e1
Historical Standard: ASTM D4922-94e1 Standard Test Method for Determination of Radioactive Iron in Water
SUPERSEDED (see Active link, below)
ASTM D4922
1. Scope
1.1 This test method covers the determination of 55 Fe in the presence of 59 Fe by liquid scintillation counting. The a-priori minimum detectable concentration for this test method is E-3 Bq/mL.
1.2 This test method was developed principally for the quantitative determination of 55 Fe. However, after proper calibration of the liquid scintillation counter with reference standards of each nuclide, 59 Fe may also be quantified.
1.3 This test method was used successfully with Type III reagent water conforming to Specification D1193. It is the responsibility of the user to ensure the validity of this test method for waters of untested matrices.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 9.
