In reading the requirement of IATF 188.8.131.52.1(shown below), my interpretation is that items a thru f should be a part of the defined scope. I have heard some people say that a thru f are requirements that needs to be specified and implemented, but do not have to be a part of the written scope. Could someone share their thoughts on the correct interpretation? 184.108.40.206.1 Internal laboratory An organization’s internal laboratory facility shall have a defined scope that includes its capability to perform in the required inspection, test, or calibration services. This laboratory scope shall be included in the quality management system documentation. The laboratory shall specify and implement, as a minimum, requirements for: a) adequacy of the laboratory technical procedures; b) competency of the laboratory personnel; c) testing of the product; d) capability to perform these services correctly, traceable to the relevant process standard (such as ASTM, EN, etc.); when no national or international standard(s) is available, the organization shall define and implement a methodology to verify measurement system capability; e) customer requirements, if any; f) review of the related records. NOTE Accreditation to ISO/IEC 17025 (or equivalent) may be used to demonstrate the organization’s in-house laboratory conformity to this requirement.
