How to Check Whether a Test Report Relates to the Batch of Parts Being Delivered

Direct answer: You cannot confirm linkage from the test report alone. Compare the order line, part number, batch or lot code, report sample identifier and delivery list. If there is a break between any of those documents, the report remains unverified for that delivery. Ask the supplier to close the gap with a physical label, packing record or written trace statement before you rely on the report.

1. Why a test report alone is not enough

A report describes a sample, not every box

A test report often records results for a sample submitted or selected at some point. It does not automatically prove that the parts inside your boxes came from the same production or packaging batch. You need a trace link from the delivered item to the sample identifier used in the report.

Separate identity, fitment, provenance and test evidence

Do not let a test report substitute for part identification. A part can be the correct model but still have no documented link to the report. Conversely, a report can be genuine but belong to a different batch. Keep these questions separate:

• Is the part the correct SANY model/suffix?
• Does it fit the serial number or installation position?
• Did it come from the stated order line?
• Does the test report's sample identifier match the delivered batch?

Model, suffix or a visual match alone never confirms fitment, batch quality or authenticity.

A photo or supplier statement is limited

A photo of a label or a statement that the 'batch is tested' is not proof of every claim. It may support a query but does not by itself authenticate the batch or replace the document chain.

2. The document chain to check

Order line and part number

Start with the purchase order line. It should show the part number, model/suffix, quantity and any agreed condition. Compare that to the supplier's delivery note.

Batch or lot code

A batch or lot code is a manufacturer or supplier code that identifies a defined production or packaging batch. Look for it on the part label, housing or carton. The code may include letters, numbers or date-related fields. Record it exactly, including spaces or dashes.

Report sample identifier

The test report should contain a sample identifier or sample reference. This may be shown as a sample ID, lot number, heat number, batch number or trace code. Do not assume these terms are interchangeable unless the report or contract defines them that way.

Delivery list or packing list

The delivery list or packing list is the document that says what boxes were shipped, with quantities and often box or pallet markings. Check that the batch code on the delivered boxes appears, or is explained, in the delivery list.

Matching sequence

The useful sequence is:

delivered box marking → part label or housing marking → batch/lot code → report sample identifier → order line and quantity.

If each step is documented and consistent, you have a much stronger basis to say the report relates to that delivery.

3. Multi-box delivery on an infrastructure project

Check whether one report covers many boxes

On a project, you may receive many boxes across pallets or trucks. One test report may cover a defined batch, but you must confirm that all boxes claimed under that report carry the same batch/lot code and that the delivery list includes that code.

Look for mixed batches

If the delivery has more than one batch code, one report may not cover all boxes. Do not assume the supplier is at fault; mixed batches can happen intentionally if surplus or separately packaged stock is combined. Ask for the report that corresponds to each batch or a written reconciliation.

Common missing links

Common breaks include:

• The report shows a supplier internal reference, but the box label shows a different customer code.
• The batch code is only on the pallet label, not on the part or carton.
• The delivery list gives a quantity but no batch or lot field.
• The report is for the same part number but a different batch date or supplier lot.

These are not automatic accusations. They are verification gaps.

4. Missing evidence and what to request

If the batch code is absent or illegible

Ask the supplier to point to the exact location of the marking and provide a trace document, not a guess. A clear photo can help, but someone still needs to confirm the marking belongs to that delivered box.

If the report sample identifier does not match

Ask whether the report uses an internal sample ID that maps to the delivery batch code. Request the written mapping or a revised report. Do not accept a verbal explanation alone if acceptance depends on it.

If the delivery list is silent on batch information

Request a delivery list or addendum that records each box, quantity and batch/lot code. For a multi-box project delivery, this is often the weakest but most important link.

Do not ask for guesses

Do not ask a supplier to 'confirm it is from the same batch' without showing the supporting record. Ask for the specific record that connects the sample identifier to the delivered marking.

5. Procurement next step

Condition of acceptance

The responsible parties—buyer, project engineer, quality representative or storekeeper—must decide acceptance using the contract and applicable SANY manuals or parts catalogue requirements. Use the checks above to decide what evidence is still missing before signing or approving payment.

If evidence is incomplete

A practical response is:

1. Hold the batch as quarantined if required by project rules.
2. Send a supplier query with the purchase order line, part number, batch/lot code, report number and photos of the label or carton.
3. Request one of these: a clear photo of the marking, a delivery list showing the batch code, or a written document mapping the report sample ID to the delivered batch.
4. Do not approve the batch as report-linked until the chain is complete.

Parts Matching Support

If you need help preparing a supplier query, MechLink may help organise candidate part and delivery information, such as model/suffix, serial number, nameplate, old part number, component or housing photos, installation position, applicable catalogue revision, documented supersession, and relevant labels or records. This does not mean MechLink authenticates reports or certifies batches. It is an external commercial information-support service, not a testing body or SANY official contact.
