The analyses of environmental samples for international safeguards has presented the agencies responsible for quality assurance with the need for a unique class of reference materials. Because of the small quantities to be measured, special consideration of the physical form of the reference materials is required. A knowledge of these physical characteristics is as important as the primary certified isotopic value. A programme to develop these reference materials in a manner which will allow international acceptance of these materials has been established and has made significant progress.
