Test scope and existing reports
State the required routine tests and identify which type or special test reports apply to the offered design. Confirm whether existing reports are acceptable or new tests are required.
QUALITY / TESTING / TRACEABILITY
Quality evidence, not just quality claims.
Incoming materials, winding, casting, drying, oil filling, assembly and final testing are controlled as documented production gates before shipment.
INCOMING MATERIALS
Control starts before production.
Steel, copper, insulation, resin, oil and purchased components are checked against project documents and approved supplier requirements. Material records remain traceable to the transformer serial number.
TESTING
Routine, type and special tests.
Define the routine, type and special tests required for the specified transformer design and governing standard. Agree the applicable reports, acceptance criteria and any additional testing before ordering.
DOCUMENTATION
Documents follow the unit.
Test reports, inspection records, nameplate data, packing lists and project documentation are prepared against the approved scope, then linked to the shipment record.
BEFORE ORDERING
Agree the inspection scope before ordering.
Confirm the test location, laboratory scope and any third-party involvement for the specified model and destination market.
Review certificates and laboratory scopeWitness and hold points
Specify buyer or third-party attendance, notice periods, hold points and release authority in the inspection and test plan before manufacturing.
Reports and traceability
Ask for the applicable standard and edition, test conditions, acceptance criteria, measured results and the unit serial number or tested design reference.
