- Scope
- This standard specifies the requirements for the content of certified reference substances and supporting documents, so that they are considered to have a higher metrological level consistent with GB/T 21415-2008. This standard applies to all kinds of certified reference materials, including primary measurement standards, secondary measurement standards and internationally agreed calibrators used for calibration or correctness control. This standard also provides how to collect data for valuation, and how to express the valuation results and their measurement uncertainty requirements. This standard is applicable to certified reference substances whose assignment results are differential values or proportional values. Appendix A provides information on nominal properties and ordinal quantities. This standard does not apply to reference substances that are part of in vitro diagnostic measurement systems, but many elements may be helpful to it.
