This practice is useful for the preparation of specimens of ore bodies for the analysis of uranium by X-ray emission. Two separate preparation techniques are described.

1.1 This practice covers the preparation of uranium ore samples to be analyzed by X-ray emission. Two separate techniques, the glass fusion method or the pressed powder method, may be used.

1.2 The values stated in SI (metric) units are to be regarded as the standard.

1.3 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.
