标准介绍
  ASTM C1502-2001 测定二氧化铀氧化钆中氯和氟的总含量的标准试验方法
  
  The method is designed to show whether or not the tested materials meet the specifications as given in either Specification C 753, C 776, C 888 or C 922.
  
  1.1 This test method covers the determination of chlorine and fluorine in nuclear-grade uranium dioxide (UO2) powder and pellets, nuclear grade gadolinium oxide (Gd2O3) powder and gadolinium oxide-uranium oxide (Gd2O3-UO2) powder and pellets.
  
  1.2 With a 2 gram UO2 sample size the detection limit of the method is 4 956;g/g for chlorine and 2 956;g/g for fluorine. The maximum concentration determined with a 2 gram sample is 500 956;g/g for both chlorine and fluorine. The sample size used in this test method can vary from 1 to 10 grams resulting in a corresponding change in the detection limits and range.
  
  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.
