Availability of reference materials: COMAR the database for certified reference materials
Accreditation and Quality Assurance, 2003COMAR is the international database for certified reference materials. A new user-friendly web-based version, COMAR2, has been developed by BAM and CONET Consulting AG which will be available in December 2002. The advantages of COMAR2 are briefly explained.

Reference materials and certified reference materials for water and food microbiology
Fresenius' Journal of Analytical Chemistry, 1993The concept of Certified Reference Materials (CRMs) for the verification of the accuracy of analytical methods and the traceability of the results to a CRM, is well accepted in chemistry. The use of Reference Materials (RMs) for intra-laboratory quality control schemes or for round-robin and proficiency testing is well established and follows from ...

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.

Certified reference materials for thermal analysis
Journal of Thermal Analysis, 1988Eight inorganic substances recommended by ICTA as temperature standard reference materials for DTA and DSC were studied: KNO3, KClO4, Ag2SO4, K2CrO4, quartz, K2SO4, BaCO3 and SrCO3. The content of pure component in each of these substances was determined by classical chemical analysis.

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
