Reconciling a supplier certificate with an independent result
Building on post #3 rather than restating it.
Reports naming a supplier need the evidence attached, which is a guideline rather than a formality. It is what makes the record usable and it is what keeps it fair.
I would want a second opinion before relying on that.
Post #7 and I disagree about the size of the effect, not about the direction.
Blind submission is worth the effort: have someone else relabel the sample so neither you nor the laboratory knows which supplier it came from until the result is back. Blind results change minds; self-selected results do not.
I am describing what is, rather than arguing for what should be.
What "verified" means on our pages: specific lots were independently measured on stated dates by named services and results were consistent with the supplier's documentation. It is not a recommendation and does not extend to untested lots.
