Repeat Test due to Defect

We had a bought out part that failed during a test. The failed part was removed and replaced and now the Contractor has to do some pre test works to get ready for the repeated test. We are the Subcontractor. The actual test isn’t that long but the pre works are considerably longer. The Contractor works are not specified in our Works Information as we have no involvement in this, can the cost for the pre test works be passed on or just the cost of the repeated test?
