Statement of conformity is not defined in ISO/IEC 17025. Decision rule describes how measurement uncertainty is accounted for when stating conformity with a specified requirement. Statement of conformity is not a default requirement I ISO/IEC 17025.
In many published normative documents (standards, regulatory framework) there is no decision rule, and the difficulty is a matter of contract review.
We see CABs report test results and MU with reference to limits in specification or standard without stating conformity, or describing how MU is accounted for. The discussion is if this is considered as a statement of facts, or if its any possibility of misunderstanding for the customer.
So, when a CAB reports the limits from specifications/standards, but not a statement of conformity, is this still subject to 7.8.6 and requirements of reporting the decision rule applies?
Is there any difference between testing- and calibration laboratories regarding statement of conformity?
When a CAB reports the limits from specifications/standards but not a statement of conformity and the client did not ask for a statement of conformity, subject 7.8.6, and other requirements of reporting, the decision rule are not applicable, but it is mandatory to include in the report all the information necessary for the client to check the compliance with the specifications as appropriate (for instance the uncertainty).
However, if the result is indicated in some other way (for instance, green letters, bold letters, red highlighted, marked *,…), it would be understood as a statement of conformity and all the relevant requirements are applicable.
No difference between testing- and calibration laboratories regarding statement of conformity.
