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

A buyer can link a parts test report to a delivered batch only through a documented chain: purchase order line, part number or documented supersession, supplier batch or lot code, test report sample identifier, and the remote-site delivery record. If any one of those links is missing or inconsistent, the report does not apply to that batch and should not be used to settle acceptance.

This is an independent information guide, not SANY official guidance, dealer advice or a certification platform.

1. Why an unlinked report cannot settle a batch question

A test report describes a sample that was tested at a specific time. It does not automatically describe the parts that arrive at a remote project site. The delivered parts can be from another batch, another production date, another revision, or another source.

Part identity, fitment, provenance, sample results and batch acceptance are separate questions. A part may be the correct model but unsupported for the specific batch. A report may be genuine but belong to a different lot. Keep these separate.

2. The document chain to request and check

Purchase order line and part identity

Start from the purchase order line. It should show the part number ordered, model or suffix where applicable, any old part number, and the applicable catalogue revision. If there is a documented supersession, the order and delivery documents should show the link between the old and new part numbers.

For parts where individual serial numbers matter, record the serial number from the nameplate. For non-serialised parts, the batch or lot code is usually the strongest traceability link. Installation position can be useful when the part is machine-specific, but it is not a substitute for a part number.

Batch or lot code and delivery record

Ask the supplier to state the batch or lot code on the packing list, delivery note or invoice line. The remote site should record that same code at goods receipt, together with quantity, delivery date, and condition of labels and packaging.

A delivery record without a batch code cannot connect a later test report to the received parts.

Test report sample identifier

The test report must identify the sample it tested. Compare the report sample identifier with the supplier batch or lot code and the part number on the delivery record. The report should also state the test method or standard and the result.

If the report only lists a part category, a brand, or a generic description, it is not traceable to the delivered batch.

Photos and labels

Component or housing photos and label photos can support identification and help organise a supplier query. They do not prove that the part was tested, that the report matches the batch, or that the part is authentic. A supplier statement is also not proof by itself; it must be checked against the documents.

3. What an unlinked report can and cannot do

An unlinked report may show that a part of the same part number was tested at some point. It cannot settle a batch question because it does not establish that the delivered units came from the tested lot.

For example, if the delivery note shows one batch code and the report sample identifier shows another batch code, the report is not evidence for the delivered batch unless the supplier provides a documented link between those two identifiers. The same applies when no batch code is recorded at the remote site.

4. Missing evidence and procurement next step

Before accepting the batch, identify which link is missing. The usual missing links are: no batch or lot code on the delivery note, no sample identifier on the test report, or no goods-receipt record at the remote site.

The next procurement step is to send a written query to the supplier requesting a traceability statement or delivery-to-test report mapping. The request should ask for the purchase order line, part number, batch or lot code, delivery note number, test report number and sample identifier to be shown in one place. If the supplier cannot provide that link, quarantine the batch and do not accept the report as batch evidence.

MechLink is an independent commercial information-support service and may help organise candidate part and delivery information for this type of supplier query. It does not authenticate reports, test parts, or certify batches. For readers in Tajikistan, the MechLink WhatsApp for parts information and procurement clarification is +77026412810. That number is a MechLink enquiry channel, not a SANY official contact and does not imply a local office or local stock.

5. Parts Matching Support

If you need to clarify part identity or prepare a supplier traceability request, collect the machine model and suffix, serial number, old part number, component or housing photos, and any label or delivery record photos. These items help MechLink organise the information for a procurement clarification. They do not replace the supplier’s own traceability documents.
