The Vickers and Knoop microhardness testing methods have become invaluable for the testing of a variety of parts, which have what can be referred to as “shallow layer hardness.” Such characteristics as surface hardness, thin cross section, coating hardness, and case depth are measured using the microhardness testing methods. These methods also can be useful for selective testing of particular grains or constituents such as those found in powdered metal parts.

Manufactured parts need to be measured to ensure they meet the original design intent. Modern manufacturing techniques allow complex parts to be made that can have numerous critical dimensions.

There is a broad spectrum of applications for portable helium leak detectors that touches numerous industry market segments. Vacuum systems as well as a wide variety of products and devices require leak testing as part of the quality testing process. 

In September, the International Organization for Standardization (ISO) published ISO 9001:2015, the updated high-level system (HLS) quality management system standard that includes some fundamental changes in how organizations are expected to operate to remain in conformance.
