How can I tell whether a test report actually relates to the batch of parts being delivered?

You cannot confirm this from the test report alone. You need to trace three separate links: the order line and part identity, the batch or lot code on the delivered parts and packaging, and the sample identifier and scope in the report. If any link is missing or contradictory, the report should be treated as unverified for that delivered batch, not as automatic batch acceptance.

1. Start with the part identity, not only the model number

A report can be genuine but still belong to a different version of a part. Check the full model and suffix, serial number where applicable, old part number if a supersession is being used, and nameplate or housing marking. A photo of a similar part is not enough.

Model and suffix

For example, a SANY part may have the same base model but different suffix for application or revision. The delivery note, part label and order line should match the exact suffix.

Nameplate and old part number

If the new part replaces an old number, record both. The old number helps confirm that the substitute is the intended supersession. Do not rely on the report alone to prove fitment.

Photos and position

Component or housing photos and installation position can help identify what was delivered, but they only support a supplier query. They do not prove batch quality or authenticity.

2. Trace the batch or lot code through the delivery

A batch or lot code is the producer's or packer's identifier for a specific production batch. The report may state a batch number, heat number, serial range or production date.

Compare at least these records

• Purchase order line: part number, quantity, any batch or lot reference.
• Delivery note: part number, quantity, batch or lot code, delivery date.
• Physical parts or packaging label: batch or lot code, production date, supplier or plant code.
• Test report: sample identifier, batch or lot code, part number, test date or report date.

Watch for mixed delivery

A multi-box delivery for an infrastructure project can contain more than one production batch. If the delivery list shows two batch codes, one report for one batch does not cover the other batch unless the report clearly lists both or there is a separate report.

Missing link

If the batch code on the report does not appear on the parts, packaging, or delivery note, there is no documented link. You should request the missing record rather than assume the report is representative. Do not invent acceptance sampling rules or accuse the supplier; just record the missing link.

3. Check the report sample identifier and scope

A test report should say what was sampled or tested, not only that a product type was approved.

What can be confirmed

You can confirm that the report's part number, batch or lot code, and sample identifier match the documents and markings of the delivered batch. You can also note what parameters the report claims were tested and whether the document is legible and complete.

What cannot be confirmed from the report alone

You cannot confirm that the sample was actually taken from the boxes in front of you, that the report is authentic, or that every item in the batch has the same properties. The report is evidence only if the identifier chain is intact and the document is checked against the applicable requirement.

Keep identity and batch evidence separate

Part identity tells you what the part is. Batch traceability tells you which production batch it belongs to. Report scope tells you what was tested or declared. A correct part number does not make a report relevant to the batch. A matching batch code does not prove fitment.

4. What missing evidence to request

If the chain is incomplete, request in writing:

• The delivery note or packing list that shows the same batch or lot code as the report.
• A clear photo of the part label, nameplate, and packaging label showing model/suffix and batch or lot code.
• The test report page or certificate that shows the exact sample identifier and batch reference.
• If a supersession is involved, the applicable parts catalogue or manufacturer document showing old and new part numbers and the revision.

Ask the supplier to point to the specific field on each document. Do not accept a general statement such as 'the report covers this delivery' unless the identifiers align.

5. Procurement decision

Only the responsible party can decide acceptance. If the identifiers align, you have a documented basis to proceed with any further inspection or acceptance step required by the project. If they do not align, hold the batch as unverified and request the missing records. A photo or supplier statement is not proof of every claim.

MechLink, an external commercial parts-information support service, may help organise candidate part and delivery information for a supplier query. It does not authenticate reports or certify batches. Use it to prepare a clean request: order line, part number, batch code, photos, and the report page that is in question.

Parts Matching Support

If you need parts information or procurement clarification, prepare model + serial number + old part number + component/housing photos and relevant labels or records.
