Data record std.ieee-c37-112.conformance-bands

Verified 2026-10-24 Confidence: High

Clause 3.4 of IEEE C37.112-2018 requires the operate times of a conforming relay to fall inside the band drawn around each standard characteristic in Figures 2 through 4 over a stated range of multiples of pickup; each band lies a fixed proportion above and below the Table 1 time.
