To evaluate the capability of an assembly to sustain internal overpressures, publication IEC/TR 61641[2] (which is a technical report) has been drafted. It provides a common reference with a standardized method for tests, as well as criteria for the validation of tests results.
IEC/TR 61641 assesses the ability of an assembly to limit the risk of personal injury and damage to the assemblies, as well as the downtime and time needed to return to service after an arc due to an internal fault.
