Annex ZA (informative) Clauses of this European Standard
         addressing essential requirements or other

Defines requirements and formats for the description of reference materials. It is applicable to reference materials of higher metrological order, classifiable as primary measurement standards and secondary measurement standards that function either as calibrators or control materials for reference measurement procedures. This standard does not apply to reference materials that are parts of an in vitro diagnostic measuring system. This standard also provides instruction on how to collect basic data for value determination and how to present the assigned value. The standard also specifies the format for a certificate.
