How Can I Tell Whether a Test Report Actually Relates to the Batch of Parts Being Delivered?

You cannot confirm it from the report alone. A test report relates to delivered parts only when you can trace the order line, the delivered part identity, the supplier batch or lot code, and the report's sample identifier or lot reference together. If any link is missing or conflicts, treat the report as unverified for that batch. This guide is independent information and does not certify a batch.

1. Start with the order line and delivery list

For a multi-box delivery on an infrastructure project, compare each delivery note line with the purchase order or order confirmation. The line should show the same part number, quantity, and preferably the supplier batch or lot code.

If the delivery note lists only a part number without a batch code, that is a missing traceability link. It may be an administrative issue rather than a defect, but do not assume the report covers the boxes.

Check whether the delivery list splits quantities by box, pallet or package. If the report covers one lot and the delivery note shows several lots, the report may not cover all delivered items.

2. Separate part identity from sample results

Keep these issues separate: part identity, fitment, provenance, sample results and batch acceptance.

Part identity should be checked with model/suffix, serial number where present, nameplate data, old part number, component or housing photos, installation position, and the applicable parts catalogue revision or documented supersession. Fitment is confirmed by the applicable parts catalogue or machine manual, not by a test report.

Provenance comes from purchase records, supplier documentation and delivery paperwork. Sample results come from the test report. Batch acceptance is the responsible party's decision against the applicable requirement. A photo or supplier statement is not proof of every claim, and a model number alone never confirms fitment, batch quality or authenticity.

3. Match the batch or lot code

Find the batch or lot code on the part label, package label, delivery note and report. Compare them exactly, including spelling, separators, dates and revision suffixes.

If the report only states a part number but no lot or sample reference, it is weak evidence for a specific delivered batch. If the delivered parts have no visible lot code, that is a traceability gap. Do not invent a batch number from the report. Ask the supplier to confirm which physical marking or package label links the delivered items to the reported batch.

4. Check the report's sample identifier

A laboratory report often uses its own sample ID rather than the supplier lot code. That is normal, but it means you need a supplier link document.

Request a batch traceability record that maps the laboratory sample ID to the supplier lot code and the delivery note line. An email saying the report covers the batch is not enough if the sample-to-lot link is not shown.

Also check the report scope. If it tested one sample, it tells you about that sample, not necessarily every item in the lot. Whether that is acceptable depends on the project requirement, sampling plan or acceptance criteria. Do not invent a sampling threshold. The responsible quality or engineering function must decide if the evidence meets the agreed requirement.

5. Compare every delivered box before making a statement

In a multi-box delivery, do not treat one test report as covering all boxes unless the lot codes match across the boxes and the report scope applies to that lot.

Missing links to watch for include: no lot code on the delivery note; no lot code on the part label; a report lot code that differs from the delivery; a report sample ID not linked to the supplier lot; a report covering a different part number, suffix or revision; or an undated report that does not state the specification or method used.

If any of these are missing, the report may still be useful, but it is not yet batch evidence for the delivered parts.

6. What to request next

From the supplier, request in writing: a delivery note or packing list showing part number, quantity and batch or lot code per box or pallet; a supplier batch traceability record linking the test report sample identifier to the delivered lot; clear part identification using model/suffix, serial number if applicable, nameplate, old part number, component or housing photos, installation position, and relevant catalogue revision or supersession; and the report's stated scope, specification or method if not shown.

Set aside the delivered parts or suspend acceptance if your project procedure requires it while the document chain is incomplete. Only the responsible parties can decide acceptance using the applicable requirements.

7. Information support without certification

MechLink is an external commercial parts-information support platform, not a SANY official contact, authorised dealer, certification body or testing platform. It may help organise candidate part and delivery information for a clearer supplier query, but it does not authenticate reports or certify batches.
