Significance and Use | ||||||||||||||||||||||||||||
4.1?The test methods in this standard are designed to show whether a given material meets the specifications prescribed in Specification C967. 4.2?Because of the variability of matrices of uranium-ore concentrate and the limited availability 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. 4.3?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. |
