Equipment Under Test [EUT]

This two-part article provides an overview of current automotive EMC standards and the intricacies of chamber testing automotive systems and components.

This article addresses the latest changes to the KS C 9814-1 (and CISPR 14-1) standard.

This article summarizes the changes in IEC 60601-1-2:2014 Amendment 1:2020 and describes how to conduct proximity magnetic fields immunity testing as required by the standard.

During the testing of one aircraft, we suffered a very marked and complete electrical failure of the aircraft (much to the alarm of both the test engineers and the cockpit crew) which turned out to be due to the EUT we were testing.

Product standards, such as IEC 62368‑1 for ITC equipment, struggle to keep up with technology changes, even when they are designed to be adaptable – such as this hazard-based standard. Unexpected consequences can develop with the introduction of disruptive technology that takes advantage of a seeming loophole in a standard and move forward without getting a full evaluation under the standard. Fault managed power systems, such as PoE, push the standard in getting proper evaluation. This paper is a case study including a detailed proposal as to how to address an issue such as this within the standard.
