ASTM E1172

Abstract

This practice covers the components of a wavelengthdispersive X-ray spectrometer that are basic to its operation and to the quality of its performance. It is not the intent of this practice to specify component tolerances or performance criteria, as these are unique for each instrument. The document does, however, attempt to identify which of these are critical and thus which should be specified. <br><em>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</em>. Specific safety hazard statements are given in 5.3.1.2 and 5.3.2.4, and in Section 7. <br>There are several books and publications from the National Institute of Standards and Technology² and the U.S. Government Printing Office^3,4 which deal with the subject of X-ray safety. Refer also to Practice E416.⁵ <br>² NBS Handbook, X-Ray Protection, HB76, and NBS Handbook 111, ANSI N43.2-1971, available from National Institute of Standards and Technology, Gaithersburg, MD 20899. <br>³ <em>Radiation Safety Recommendations for X-Ray Diffraction and Spectrographic Equipment,</em> No. MORP 68-14, 1968, available from U.S. Department of Health, Education, and Welfare, Rockville, MD 20850. <br>⁴ U.S. Government Handbook 93, Safety <em>Standards for Non-Medical X-Ray and Sealed Gamma-Ray Sources</em>, Part 1, General, Superintendent of Documents, available from U.S. Government Printing Office, Washington, DC 22025. <br>⁵ For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at service@astm.org.
