Delivery records

Review the inspection file, package identification, transport protection and handling information before dispatch.

Delivery file
Required inspection and packing records

Material loss data and finished-core test results are separate records. The order defines the inspection scope, test conditions and documents supplied.

Apply these checkpoints to the agreed transformer core manufacturing and supply scope. For cut lamination orders, define piece dimensions, identification and inspection records before release.

RFQTechnical review

Define the inspection scope

State the drawing revision, acceptance criteria, required records and any witness point in the enquiry.
