Measurement and Results - Is Os traceable to NIST?
Is CGOS1 really tracable to NIST? What is the NIST catalog number?If not traceable to NIST, what is the reference material and batch number?

Osmium (product CGOS1) is certified based upon a gravimetric preparation that is NIST-traceable through comparison to master weights; i.e., the weights used in the manufacturing process are traceable to NIST. However, it is not possible to obtain direct traceability to a NIST SRM© (Standard Reference Material) for Os, as NIST does not produce an Os SRM. |
