Traceability - Checklist from NIST

Checklist from NIST:
(broken link removed) section I.A.5

To support a claim, the provider of a measurement result must document the measurement process or system used to establish the claim and provide a description of the chain of calibrations that were used to establish a connection to a particular specified reference. There are several common elements to all valid statements or claims of traceability:

1) a clearly defined particular quantity that has been measured
(easy- measurements are provided)

2) a complete description of the measurement system or working standard used to perform the measurement
(don't have it yet, but will refer to a doc that does this)

3) a stated measurement result, which includes a documented uncertainty
(of course this is on a cal cert)

4) a complete specification of the reference at the time the measurement system or working standard was compared to it
(not sure what this is supposed to be- help me out!)

5) an ‘internal measurement assurance’ program for establishing the status of the measurement system or working standard at all times pertinent to the claim of traceability
(I think this means the measuring device is in a cal. system, right?)

6) an ‘internal measurement assurance’ program for establishing the status of the specified reference at the time that the measurement system or working standard was compared to it
(I think this means the standards used to cal the measuring device must be in a cal system, right?)


Comments on the completeness of this checklist?

I really need a good decoding of what this means:

A complete specification of the reference at the time the measurement system or working standard was compared to it


What are they looking for here? Help!
