Certified Reference Materials for the Characterisation of Multifunctional Materials
Materials Science Forum, 2005Multifunctional materials are created by intimately integrating different materials. The assessment of the local properties and composition of the different components of such a multifunctional material necessarily relies on techniques with sufficient spatial resolution.

Certified reference materials and reference methods for nuclear safeguards and security
Journal of Environmental Radioactivity, 2013Confidence in comparability and reliability of measurement results in nuclear material and environmental sample analysis are established via certified reference materials (CRMs), reference measurements, and inter-laboratory comparisons (ILCs). Increased needs for quality control tools in proliferation resistance, environmental sample analysis ...

COMAR — database for certified reference materials
Fresenius' Zeitschrift für analytische Chemie, 1988With more than 130 producers of reference materials (RM) throughout the world, it is often difficult to find the best reference material for a specific application. The computer database COMAR has been developed to aid chemists in finding the needed reference material.

Reference materials for thermal expansion: certified or not?
Thermochimica Acta, 1993Abstract Many dilatometers in common use can have significant systematic errors in determining linear thermal expansion as evidenced by round-robin measurements on reproducible materials. The need for reference materials to check these dilatometers can usually be met by rods of OFHC Cu, semi-conductor grade Si, W, Pt (rather expensive!), sapphire (of

Accreditation and the need for certified reference materials
Mikrochimica Acta, 1996The comparability of data from accredited laboratories is not always as good as customers would desire. A number of reasons for this fact are given. Clients of laboratories do not specify methodology, which may lead to the application of systematically different methods or to methodology with improper performance characteristics.
