ASTM C708-08

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. , , 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.  
1.3 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.
