How can a buyer link a parts test report to the batch delivered to a remote project site?

A buyer links the report by proving one closed chain: purchase order line → part number and suffix → batch or lot code on the delivered goods → sample identifier in the test report → delivery note at the remote site. Do not accept a report merely because it shows the same part number.

1. Direct answer: build a traceability chain before acceptance

At receipt, separate two questions. One is part identity: does the part match the machine and position? The other is batch evidence: does the test result belong to the exact batch that arrived?

A report can be linked only when all five points agree:

• The part number and suffix on the report match the order line and the delivered part label.
• The batch or lot code on the report matches the batch code on the packing list or delivery note.
• The report sample identifier can be traced by the supplier to that batch in a batch record, sampling record or test request.
• The delivery record at the remote site records the same batch code, quantity and date.
• Any supersession from an old part number to the current part number is documented, so the report is not for an obsolete item.

If any point is missing, do not treat the report as batch evidence. Ask the supplier for a written traceability link instead of guessing from photos.

2. Why an unlinked report cannot settle a batch question

A test report for the same part number may come from another production lot, another material heat, another plant, another date or another customer's remaining stock. That means it cannot answer whether the batch in front of you passed the sampled test.

The report proves something about a sample, not about every delivered part. It only becomes useful for the delivered batch when the sample identifier is tied to the same batch or lot code, and the receiving record shows that batch code arrived at the site.

A photo of a label or a supplier statement such as 'same part, same quality' is not enough unless the traceability record supports it. Fitment, batch quality, authenticity and test acceptance are separate claims. A part can be visually correct for installation but still lack batch-level test linkage.

3. Useful checks before asking for missing evidence

Check the order and delivery record

Compare the purchase order line, part number, suffix, quantity and received batch code with the packing list and delivery note. If the batch code is missing at the site, photograph the label or stencil before moving parts into storage.

Check part identity separately

Use the machine model and serial number, old part number if available, nameplate, component or housing photos and installation position. Do not use a test report alone to confirm fitment.

Check the report sample identifier

Look for a sample ID, batch or lot code, test date, specification or method, result, condition and release signatory. Then ask the supplier: 'Please confirm this sample ID belongs to the batch code on delivery note ___ for PO ___ and part ___ .'

Check supersession and catalogue revision

If the part number has changed, request the documented supersession from old part number to current part number. The report should align with the applicable catalogue revision for the part actually ordered.

4. Missing evidence to request from the supplier

Request these items in writing:

• A traceability record or batch record linking purchase order, part number, batch/lot code, sample identifier and delivery note.
• A certificate of conformance or batch release note for the same batch code.
• If a third-party laboratory issued the report, the lab report number, sample ID and sampling method, plus who sampled the parts.
• A receiving record at the remote site showing the same batch code, quantity, date and condition.

If the supplier provides a generic test report for the same part number but no batch-to-sample link, mark that report as unlinked and keep the material in quarantine until the question is resolved.

5. Procurement next step

Prepare a single written query using the inspected evidence, not a broad request. For example, ask:

'For PO ____, part number ____, batch/lot ____ delivered to site ____ on ____, please provide the test report whose sample identifier matches this batch, and the batch record or release note linking the sample ID to the delivery note.'

Do not mix fitment, authenticity, sample results and batch release into one assumption. Ask the supplier to answer the sample-to-batch question first.

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

6. Parts Matching Support

Parts Matching Support: Before sending a parts information or procurement clarification, gather the machine model and serial number, old part number, component or housing photos, and any labels or records showing the batch or lot code. That helps keep part identity separate from batch evidence.
