No. A 3.1 inspection certificate/factory calibration certificate is only used to list single measured values and can't be used for traceability. The statement that a 3.1 inspection certificate/factory calibration certificate documents the traceability is only acceptable if: the reference standards used are traceable and an accredited calibration procedure (validated procedure) described in a normative document, was properly used. On cost grounds, this is only used in a reduced form in many cases. 3.1 inspection certificates/factory calibration certificates from accredited testing and calibration laboratories must be treated like calibration certificates from non-accredited institutes.
