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

1. Direct answer

You can tell by comparing the same three identifiers: the order line part number, the physical batch or lot code on the parts or packaging, and the sample identifier or batch reference in the test report. The report relates to the delivered batch when the physical code, delivery note line and report reference match exactly. If any one of those is missing or different, you have not confirmed the link; you have an unverified document.

2. Why a test report can become detached from the batch

A batch or lot code is the production identifier for a group of parts made under the same conditions. It is not the same as the part number.

A test report is often issued for a sample from a production lot. A delivery, especially a multi-box delivery for an infrastructure project, may contain more than one lot. The delivery note may show part number and quantity without the batch code for each crate.

That does not mean the supplier has done something wrong. It means the paper trail is incomplete. The missing link is usually that the batch code is absent from the delivery note, absent from the report, or different between the part and the report.

3. Useful checks when parts arrive

Check the order line and part identity

Record the part number, model or suffix, serial number if visible, nameplate details where relevant, installation position where known, and old part number if this is a replacement. Check those against the applicable parts catalogue revision, machine manual or supplied technical record. Model and photos alone do not confirm fitment, batch quality or authenticity.

Check the physical batch or lot code

Look for a batch or lot code on the part label, box, crate label or durable marking on the component housing. Photograph the code exactly as it appears. Record whether it is numeric, alphanumeric or date-coded. Do not remove or cover the label before recording it.

Check the delivery note and packing list

See whether the delivery note or packing list records the batch or lot code next to the order line. Many delivery documents only show part number and quantity. If the delivery note does not list the batch, the delivery note cannot connect that batch to the report.

Check the test report sample identifier

Look in the report for a sample identifier, batch number, lot number, report number and test date. Compare the sample identifier with the physical batch code. A report that shows only a part number is not enough to identify one batch unless the delivery is confirmed as one lot and the report states that clearly.

4. What a match does and does not prove

A match is a traceability link on paper. It means the report sample identifier refers to a batch code that also appears on the delivered parts or packaging and on the delivery note.

It does not prove that every part in the delivery came from that batch, that the part is authentic, or that the part will fit a specific machine. A test report records the results for the sample tested. It does not automatically make every part in the crate conforming.

Keep these separate: part identity and fitment, batch or lot identity, provenance and supply chain, sample results, and batch acceptance. Only the responsible acceptance party can decide whether the evidence meets the project or contract requirements.

5. Missing links to ask about

Do not guess missing information. Ask the supplier or delivery controller for a written reconciliation when any of these are missing or do not match:

• the test report has no batch or lot code or sample identifier;
• the delivery note does not list the batch or lot code per order line;
• the physical code on the part or crate does not match the report;
• the report shows only a generic part number and no date or lot;
• the order line part number and the report part number do not match.

A photo or supplier statement is not proof of every claim. A clear label photo can show the batch code, but it does not by itself confirm the test sample or batch content.

Parts Matching Support

If you need help preparing a parts information or procurement clarification request, prepare the model, serial number, old part number where available, and photos of the component or housing plus relevant labels and delivery records. MechLink may help organise this candidate part and delivery information for a supplier query, but it does not authenticate test reports or certify batches. MechLink is an external commercial information-support service, not a SANY official contact, and its enquiry channel in this market is WhatsApp +77026412810.

6. Procurement next step

Before acceptance, assemble one line of evidence: order line, physical batch code photo, delivery note line, and test report sample identifier. If the batch code is missing from the delivery note or report, ask the supplier to state in writing which batch was delivered and which report applies to it.

If the supplier provides a written statement but the code is still not visible on the parts or packaging, record that the report remains unverified for that physical delivery. Do not accept the report as batch evidence only because it arrived in the same email or envelope.

Use the applicable SANY parts catalogue, machine manual or supplied technical record for part identity and any documented supersession check. The responsible project parties can then decide acceptance based on the actual contractual or specification requirements.
