Type-testing for electronic energy meters requires a bunch of various test, not only for metering and accuracy, but also for environmental conditions and inflammability. The glow-wire test is part of the type-test procedure according to IEC. See the description and a short video in the article.

The glow wire flammability test is used to simulate the effect of heat that may occur in malfunctioning electrical energy meters, such as when components are overloaded or glowing.
