Five years helping electrical-steel makers and core builders agree how core loss is tested, graded and certified
The School of Continuous Improvement's Impact Report 2021–2026 recounts five years with a consortium of electrical-steel producers and core builders over how a core-loss figure travels from test frame to purchase order. It reports three case studies: a blind round-robin of eleven laboratories whose spread narrowed once each frame carried its own record, a grading scheme whose two middle bands separated nothing a buyer could detect and were merged, and a custody audit of the reference sheets every frame is checked against.
