A competent ISO 9001 auditor should have the necessary auditing skills to assess conformance of management requirements of any quality management system, thus in ISO 17025 all the clauses of Clause 8. This is because the management requirements are based on ISO 9001, and the auditor would use an ISO 17025 checklist and your own documented procedures as the criteria. 

The shortfall is that an ISO 9001 auditor would not be able to audit the technical requirements of 17025 – in fact, many ISO 17025 lead auditors would not be able to either, if they have no technical knowledge of ISO 17025 and the test methods. It requires knowledge of techniques and method risks.
