Data record tests.relay-51-time-overcurrent-test.ieeec37-112.conformance-check

Verified 2026-10-24 Confidence: High

A timing check that uses the conformance criteria of IEEE C37.112-2018 places its test points inside the range of multiples of pickup that clause 3.4 names and judges the shape of the curve against the conformance bands, while timing accuracy is judged against the relay manufacturer tolerance because the bands are not accuracy limits.
