Standard Test Methods for Chemical and Atomic Absorption Analysis of Uranium-Ore Concentrate
适用范围：<p>The test methods in this standard are designed to show whether a given material meets the specifications prescribed in Specification <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?C967-HTML">C967</a>.</p> <p>Because of the variability of matrices of uranium-ore concentrate and the lack of suitable reference or calibration materials, the precision and bias of these test methods should be established by each individual laboratory that will use them. The precision and bias statements given for each test method are those reported by various laboratories and can be used as a guideline.</p> <p>Instrumental test methods such as X-ray fluorescence and emission spectroscopy can be used for the determination of some impurities where such equipment is available.</p><p id="s00002">1.1 These test methods cover procedures for the chemical and atomic absorption analysis of uranium-ore concentrates to determine compliance with the requirements prescribed in Specification <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?C967-HTML">C967</a>.</p>
