Inside Hill Engineering’s Quality Control Program

In a previous post, we highlighted the steps we took to develop a Quality System that is compliant with ISO. Since then, we have successfully completed three renewal audits and are currently accredited to ISO/IEC 17025:2017, the most recent revision of the standard. Part of our Quality System requirements includes the creation and maintenance of a quality control program for the various residual stress measurement techniques we perform in our laboratory. Consistently providing high quality results to our customers is something we pride ourselves in and the best way for us to assure that is through a quality control program.
