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.
