Warnung (Datum: 16.07.2026): veraltet!
Für akkreditierte Labore (mit durch die Akkreditierungsstelle "zugewiesener" (Urkunden-)Nummer lässt sich der Inhalt des basic_calibrationMark augenscheinlich aus den drei Feldern basic_certificateNumber (-&gt; dcc:value) mit der Kalibrierscheinnummer), dcc:calibrationLaboratoryCode und dcc:endPerformanceDate generieren. </skos:definition> <skos:definition xml:lang="en">Complete alphanumeric content of the calibration mark.
 
Warning (Date: 07/16/2026): deprecated!
For accredited laboratories (with an (accreditation) number "assigned" by the accreditation body, the content of the basic_calibrationMark can apparently be generated from the three fields basic_certificateNumber (-&gt; dcc:value) with the calibration certificate number), dcc:calibrationLaboratoryCode and dcc:endPerformanceDate. </skos:definition> <skos:scopeNote xml:lang="en-EN">The calibration mark usually is the visual display of the calibration mark according to ILAC P8:03/2019, Section 8.1 </skos:scopeNote> <skos:scopeNote xml:lang="de-DE">Die Kalibriermarke ist normalerweise die visuelle Darstellung des Kalibrierzeichens nach ILAC P8:03/2019, Section 8.1 </skos:scopeNote> <skos:scopeNote xml:lang="ab">The content depends on regulations of the accreditation body (such as published for Germany by DAkkS GmbH) and may vary. </skos:scopeNote> <skos:scopeNote xml:lang="de">Der Inhalt hängt von Regelungen der Akkreditierungsstelle (so wie für Deutschland von der DAkkS GmbH veröffentlicht) ab und kann variieren. </skos:scopeNote> <skos:historyNote xml:lang="en-EN">
