Referring to clause 5.3 in ISO/IEC 17025:2017, what is a sufficient level of detail in a CABs documented and registered range of laboratory activities for which they claim compliance to the standard?
Does the documented range of activities need to contain details in line with ISO/IEC 17011:2017 clause 7.2.1c and clause 7.8.3? If so, can NABs define the limits of capability, where applicable, to be included (such as objects, instrumentation, parameters, measurement ranges, measurement uncertainties, etc…)?
ISO/IEC 17025:2017 requires a laboratory claiming conformity with the Standard to express a scope defining the boundary of the competence claimed. If a laboratory is involved also in Accreditation this will equal or exceed the scope agreed with the Accreditation Body, but need not necessarily be expressed in such detail as the Accreditation Body and ISO/IEC 17011 may require for the scope of accreditation.
An important point is that no CAB may depend on an AB for its conformity. It follows therefore that the Lab may use the scope given by the AB as its description if it wishes but this should be presented directly and kept up-to-date. It should not be just a link to the AB’s website as this would constitute a dependency
