(Specification)Standard Specification for Nuclear-Grade Beryllium Oxide Powder
Standard Specification for Nuclear-Grade Beryllium Oxide Powder
SCOPE
1.1 This specification defines the physical and chemical requirements of nuclear-grade beryllium oxide (BeO) powder to be used in fabricating nuclear components.
1.2 This specification does not include requirements for health and safety (1-5).2 It recognizes the material as a Class B poison and suggests that producers and users become thoroughly familiar with and comply to applicable federal, state, and local regulations and handling guidelines (1).
1.3 Special tests and procedures are given in Annex A1 and Annex A2.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
