Deskripsi
RM (Reference Material)
Reference Material (RM) - Material, sufficiently homogeneous and stable with respect to one or more specified properties, which has been established to be fit for its intended use in a measurement process.
Feature:
- RM is a generic term.
- Properties can be quantitative or qualitative, e.g. identity of substances or species.
- Uses may include the calibration of a measurement system, assessment of a measurement procedure, assigning values to other materials, and quality control.
- A single RM cannot be used for both calibration and validation of results in the same measurement procedure.
- International Vocabulary of Metrology – Basic and General Concepts and Associated Terms has an analogous definition (VIM - ISO/IEC Guide 99:2007, 5.13), but restricts the term ''measurement'' to apply to quantitative values and not to qualitative properties. However, Note 3 of ISO/IEC Guide 99:2007, 5.13, specifically includes the concept of qualitative attributes, called ''nominal properties''.
(ISO Guide 30:1992/Amd 1:2008)
CERTIFIED REFERENCE MATERIAL (CRM)
Reference material characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty, and a statement of metrological traceability
- The concept of value includes qualitative attributes such as identity or sequence. Uncertainties for such attributes may be expressed as probabilities.
- Metrologically valid procedures for the production and certification of reference materials are given in, among others, ISO Guides 34 and 35.
- ISO Guide 31 gives guidance on the contents of certificates.
- VIM has an analogous definition (ISO/IEC Guide 99:2007, 5.14).
(ISO Guide 30:1992/Amd 1:2008)
SETTING-UP SAMPLES (SUS)
Setting-up Samples (SUS) have an uncertified analysis and to be used as a guide. They are used to meet the day-to-day setting-up requirements or shift-to-shift adjustment of spectrometers or instrument for production control analysis. This process is usually called ''drift correction'', ''standardization of the calibration'', or ''re-standardization'' depending on manufacturers. The quality of SUS samples is to be homogeneous.
