Disclaimer

Information at cmmcalibrationpittsburgh.com is published as general description, to help a requester understand what can be arranged and what a request should contain. It is not a technical specification. It is not an engineering opinion. It is not a certificate of any kind.

Current version: 9 October 2026.

Nothing about a measurement result stands apart from its uncertainty. Reading it correctly means reading it alongside three things: the measurement uncertainty stated on the certificate, the conditions under which the measurement was made, and the method used.

A tolerance is what a statement of conformity is tested against, pass or fail, and the decision rule behind that test is agreed before the work is performed, never here. No part of this site states or implies a decision rule, an uncertainty figure, or a conformity outcome for any item.

One document reports results: the certificate or report issued by the laboratory that performed the work, in the form in which it is issued. Pages of this website do not report results, and neither do emails or verbal statements made while arranging work — none of them is a certificate of calibration, a report of results, or an amendment to either. Certificates are valid as complete documents and should be read that way.

ISO/IEC 17025:2017 is the standard the work described here is performed under. Where accreditation is referenced, the accreditation is that held by the laboratory performing the work, and it extends only to the measurements listed in that laboratory's published scope. Work falling outside a published scope is performed and reported as non-accredited work, identified as such on the certificate.

Advice is not what this site provides — not engineering, not metrological, not legal, not regulatory — and nothing on it must be relied on to decide whether an instrument is fit for a particular use. Any external link is a convenience only, and its content is not controlled or endorsed. To the extent permitted by law, liability for action taken on the basis of website content alone is not accepted.
