As they apply to INSPECTION, yes.....same as when ISO/IEC 17025:2005 makes the statement it applies to testing and calibration.....
In the case of both ISO/IEC 17020 and 025, the QMS requirements are fulfilled because they are specific to the Standard and types of activities carried out.....
In other words, if your organization is accredited to ISO/IEC 17020 and/or 17025, you do NOT also need ISO 9001 for those activities.....you may still need 9001 for other activities however.....
