Title: reference material certificate Long Title: IUPAC Gold Book - reference material certificate DOI: 10.1351/goldbook.08117 Status: current Definition Document, issued by a reference material producer, containing the essential information for the use of a certified reference material and confirming that the necessary procedures have been carried out to ensure the validity and traceability of the stated property values. Notes 1) A reference material certificate is usually valid for a stated period of time ("period of validity" or as described by its "expiry date"), which defines the shelf life of the certified reference material. 2) Documents containing the information described above may not, for legal or other (non-technical) reasons, be termed "certificate" (compare Note 1 to certified reference material). 3) ISO Guide 31 is the guidance document to the required and recommended content of a reference material certificate. 4) In this definition, "traceability" covers both metrological traceability of a measurement result and examination traceability, but not object traceability.
