Certified Reference Materials (CRMs) are ‘controls’ or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments.
A certified reference material is a particular form of measurement standard. Reference materials are particularly important for analytical chemistry and clinical analysis. The use of Certified reference materials (CRMs) and reference materials (RMs) provides one of the ‘foundation stones’ for quality assurance in both measurement, and calibration laboratories.
Used correctly, they provide a direct route to verification of assigned measurement values. The reference materials contained in this catalogue are made available world-wide through the JRC-Geel's Reference Materials Unit and its authorised distributors.
They can be purchased from the European Commission Directorate General Joint Research Centre Directorate F – Health, Consumers and Reference Materials Reference Materials UnitFile Size: 1MB.
Certified Reference Materials (CRMs) ATCC Certified Reference Material is reference material which is homogeneous and stable with respect to one or more specified properties and for which traceability and values of uncertainty at a stated level of confidence are established, where applicable.

Our CRMs are widely recognized for their uniformity and accuracy of : $ Certified Reference Materials (CRMs) are cornerstones of modern analytical quality assurance because they allow calibration of instruments, validation of methods, and quality control of methods and laboratories based on traceability and comparability of measurement.
Certified reference materials—Canadian ores, rocks, concentrates, tailings, soils, alloys, anodes and radioactive materials—are used as standards to validate analytical measurement methods or to calibrate analytical instruments used in analytical chemistry.
These standards support decision-making around mineral resource production. Frequently Asked Questions Is the exam open-book. All ASQ exams are open-book. All reference materials (e.g., including all forms of notes) must be bound and remain bound during the exam.
Bound refers to material permanently bound by stitching or glue and materials fastened securely in its cover by fasteners, which penetrate all papers (e.g. Certified reference materials (CRM) are sample materials of known composition and other qualities that can be used for calibration, quality control, and related many regions, standards agencies regulate who can produce certified reference materials, distinguishing between these and materials without certifications by only allowing facilities that meet specific standards to issue.
Reference materials play an important role in analytical chemistry, where they are used by analysts for a variety of purposes, including: checking and calibrating instruments; validating methods and estimating the uncertainty of analytical measurements; checking laboratory and analyst performance; and internal quality control.

ISO definition: A reference material accompanied by a certificate – One or more property values are certified by a procedure that establishes: • Traceability • Uncertainty – Contains supplementary information • Certifying bodies • Methods of Measurement • Material preparation.
Exam candidates should be aware that the PMI Agile Certified Practitioner (PMI-ACP) examination is not written according to any single text or singularly supported by any particular reference.
PMI does not endorse specific review courses, resources, references or other materials for certification preparation. To meet the needs stemming from research and from problems and challenges faced by chemists, analysts, and toxicologists, the number of certified reference materials should be continuously increased.
