What is the Technical Difference Between DUT and UUT?

March 12, 2026

Interface Tech Talk reviews the subtle differences when referencing a device under test (DUT) versus a unit under test (UUT). The distinction between DUT and UUT ultimately clarifies the test context, whether it is an isolated component under development or a finished unit undergoing final validation.

Interface Solutions for Heavy Equipment

July 20, 2023

Interface force measurement solutions play a crucial role in the design, testing, and use of heavy equipment and vehicles including excavators, bulldozers, loaders, cranes, lifts, mixers, pavers, and compactors. Many considerations in designing heavy machinery are mandated by force limitations and equipment performance testing. Measurement for testing and monitoring come from our high-accuracy load cells, load pins, tension links, load shackles and other weight, force and torque measurement products.

Understanding GUM and Measurement Uncertainty

June 29, 2023

GUM, the Guide to the Expression of Uncertainty in Measurement, defines terms and concepts related to uncertainty. GUM describes methods for uncertainty calculation, and offers guidance for reporting and the documentation of uncertainties in measurement results. Interface knows that understanding GUM and the adherence to good test and measurement practices are essential to minimize uncertainties and ensure reliable measurement results for every application. In addition, reducing uncertainty with regular calibration of testing devices and proper maintenance of the equipment go hand-in-hand with GUM.
