Many company owners or managers are frequently asked by staff to consider bringing gage and instrument calibration in-house. It can be difficult for managers to evaluate such requests beyond the usual cost/benefit considerations as the technical elements to it all can create a functional nightmare.
One reason often used in such requests is delivery times using outside sources, something that could be fixed by trying a different source. Technical competence is another reason after endless arguments over measurements from alternate sources. In this case it could be that your company has requirements unlike anyone else or your staff has unrealistic expectations of what is ‘standard’ with respect to what is offered by one or more labs. An example of this could be that your staff can’t find a lab whose uncertainty is what they believe is needed for your work. It could be that what they want is beyond today’s technical reality and should be reviewed.
