Committee C-26 Safeguards Statement44.1 The material (plutonium nitrate) to which these testmethods apply is subject to nuclear safeguards regulationsgoverning its possession and use. The following analyticalprocedures in these test methods have been designated astechnicall

However,adherence to these procedures does not automatically guaran-tee regulatory acceptance of the resulting safeguards measure-ments. It remains the sole responsibility of the u
