Delivering high quality residual stress measurement results to our customers is a top priority for Hill Engineering, and one way we ensure that is by maintaining an active ISO/IEC 17025 accreditation. We recently went through an external assessment to renew our accreditation status that looked at the inner workings of our quality management system and laboratory processes.

Background
Hole drilling is a measurement technique used to determine near surface residual stresses and has been codified in ASTM E837-20. In ASTM E837-20, the minimum allowable distance to a free edge is prescribed as 1.5 times the gauge circle diameter.
Objective
This work examines the effect arising from the distance from a free edge on a hole drilling measurement and provides an approach to determine residual stress for measurements where the edge distance is closer than that currently permitted by ASTM E837-20.

In an early blog post, we discussed Hill Engineering’s efforts to build and maintain a Quality System that is compliant with ISO 17025. More recently, we touched on our quality control program, which we use as an important check to make sure that our measurements are being carried out according to established procedures and meeting certain quality requirements. Now we’re back to give another glimpse into our Quality System and talk about another important aspect, our internal audit program.
