Testing of raw material
For every lot of CRGO coils received, samples are checked for electrical and physical properties of the material. These samples are tested in accordance with IS 649 for core loss, insulation resistance, stacking factor and bends.
Testing of finished goods:
'Before dispatch, various parameters such as length, width, burr level, stack height, thickness, surface insulation and edge camber are checked. No load losses are tested for assembled cores’
