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

1. Short answer

A test report can be considered linked to the delivered batch only when four records point to the same thing: the order line, the physical part identity, the batch or lot code on the parts or packaging, and the sample identifier on the report. If any one of those is missing or conflicts, treat the report as not yet linked to that delivery.

2. Why this is a batch-trace question, not a quality question

A test report is evidence about the sample named on the report. It is not automatically evidence about every part in a later delivery. For a multi-box delivery, boxes may contain different production dates, different batch codes or substituted part numbers. That is not proof of wrongdoing; it is a normal traceability gap.

Keep five ideas separate:

• Part identity: which part number, suffix, serial number or supersession applies.
• Fitment: whether that part is suitable for the machine.
• Delivery line: which items were actually supplied.
• Batch/lot code: which production batch the parts came from.
• Sample result: which batch or sample was tested and what the report says.

A supplier statement or a photo of a label is useful but is not the same as a completed document link.

3. Start with the order and delivery line

First compare the purchase order line with the delivery list or packing list.

Record:

• SANY part number and suffix.
• Old part number, if the machine or previous record uses one.
• Quantity per batch or box.
• Any batch, lot, date or heat code on the delivery list.
• Any remark such as batch trace attached or report applies to line 2 only.

Do not assume one test report covers the whole order. Ask which delivery line or which box it belongs to.

4. Check the physical part and packaging identity

Next look at the actual parts, labels, nameplate or housing.

Relevant physical evidence includes:

• Part number and suffix.
• Serial number, if the part is serialised.
• Production date, batch or lot code.
• Old part number on the label or casting.
• Installation position, such as left or right, front or rear, if relevant.

Take clear photos of the labels and the complete part or housing. A photo of the part is helpful for a supplier query, but it does not by itself confirm the test report applies.

5. Read the test report as sample evidence, not delivery proof

Open the report and find the sample identifier fields.

Compare them with the delivery list and physical labels:

• Sample part number and suffix.
• Sample batch or lot code.
• Sample serial number, if any.
• Production date or date of manufacture.
• Test date or report date, where present.
• Supplier or manufacturer name on the report.
• Any stated standard, specification or reference number.

If the report has a different batch code from the parts in the box, it is not linked to that delivery. If the report has no batch code and only a part number, it may only show that a part of that type was tested at some point. It does not prove the delivered batch was tested.

Do not add a sampling threshold or assume a certain percentage of parts from a batch were tested. The report shows what was sampled as stated by the issuer, nothing more.

6. Missing links in a multi-box delivery

For an infrastructure project delivery with several boxes, expect a line-by-line trace.

A missing link may look like:

• The delivery list shows two batches, but only one report is supplied.
• The report states batch B-2025-07-11, but the box label states B-2025-06-28.
• The report has no sample identifier matching the delivery list.
• The delivery list simply says test report supplied without naming the box or line.
• The part number on the report matches, but the old part number or suffix does not.

These are not accusations. They are ordinary document gaps. Ask the supplier to reconcile them in writing.

7. Procurement next step

Send a short supplier query with one line per box or delivery line:

• Delivery line number.
• Part number and suffix.
• Batch or lot code from the box.
• The report number, sample ID or batch code claimed to apply.
• Any conflicting label or missing field.

Ask the supplier to confirm the exact sample identifier to delivery-line link. If the supplier cannot link them, do not use the report as acceptance evidence for that batch.

MechLink, an external commercial parts-information service, may help you organise candidate part numbers, label photos, delivery-line notes and report references into a clear supplier query. It does not authenticate reports, certify batches or replace the supplier's written reconciliation.

Parts Matching Support: if you need parts information or procurement clarification, prepare the machine model, serial number, old part number, component or housing photos, and any labels or records.

No external catalogue, website or manufacturer database was inspected for this answer. The checks described use the buyer's own purchase order, delivery list, physical part or packaging labels, and the supplier-issued test report supplied with the delivery. The acceptance decision remains with the responsible parties using the applicable contract, project specification and manufacturer requirements.
