Standard for Calibration Intervals

Abstract

German Armed Forces had been tasked by International Military Metrology Conference (IMMC) to draft Annex C (Regulations for setting up Calibration Intervals) to the existing Standardization Agreement (STANAG) for Calibration Documentation (STANAG 4704). Setting up the calibration interval is mandatory according to ISO 10012 and ISO 9001:2008. ILAC-G24 is the guideline for the determination of calibration intervals of measuring instruments, IEC-IECEE 2007 OP-AAG010-Ed.1.1 2005-12-09 provides basic information for setting up calibration intervals for test equipment. Both standards refer to RP-1 for further information. RP-1 is very comprehensive (179 pages) and lists several methods to determine calibration intervals. Responsibility to set up calibration intervals lies within the owner of the test & measuring equipment. Most documents are only known by metrologists working in standard calibration laboratories. The new annex C to STANAG 4704 shall provide a short summary of these documents and provide guidance for the owner of the test & measuring equipment to set up calibration intervals properly.
