Alexander,
The short answer to your question is "yes".
Is this a new process/organization/startup? Is the organization ISO registered? Is there a quality program in place? Are you waiting on FDA approval?
Say you have instruments that you want to get calibrated. You either have the capability of performing them in-house, or not. If you are going to send them out, you would do good at this point to find an ISO 17025 lab to calibrate your instruments for you.
You need to identify what process this equipment will be used for. This should help you identify what criteria you will need for the equipment. The equipment you have should be calibrated to MFG. specifications. However, you still need to assure the equipment will satisfy your process requirements.
