EN 10204 3.1 vs 3.2 is a document question to resolve before ordering aluminum material. Start with the requirement in your purchasing or project records. Ask the supplier to confirm the proposed document type, the people involved in validation and the results that will accompany the delivery.
A short entry such as “material certificate included” leaves these questions open. This guide gives buyers four practical order checks, with a fictional example showing how to close a mismatch before stock reaches the cutting workflow.

EN 10204 3.1 vs 3.2: who validates the document?
Penflex Engineering Bulletin 121 explains the EN 10204:2004 document types. Both 3.1 and 3.2 state order compliance and include specific inspection results. Type 3.1 is validated by the manufacturer’s authorized inspection representative, independent of manufacturing. Type 3.2 adds either the purchaser’s authorized inspection representative or an inspector designated by official regulations. For 3.1, the product specification, applicable regulations and rules, or order define the tests and test unit.
Use the applicable standard and your actual order requirement for a formal document review. The bulletin supplies a terminology reference; this article does not assess a supplied certificate or determine your project’s obligations.
Check 1: find the requirement before comparing offers
Locate the clause that controls your purchase. Record its document number and revision, the item it covers and the person responsible for interpreting it. Keep the exact requirement available when requesting quotations.
If the requirement says 3.2, write 3.2 in the inquiry. If it says 3.1, write 3.1. If it simply says “certificate,” ask your responsible reviewer to clarify the intended document before treating an offer as complete.
Separate this question from the material specification. An aluminum grade, a temper, a product size and an inspection document type are separate entries in the purchasing record. Leaving one field clear does not resolve the others.
Also identify the supply scope. Are you buying full stock lengths, cut blanks or a finished assembly? Keep the document request attached to the actual line item, so the seller can explain what evidence will accompany that supply.
Check 2: resolve an incomplete offer while changes are manageable
Consider a fictional order for 24 aluminum blanks under drawing Q31, revision C. The buyer’s controlled purchasing note calls for a 3.2 inspection certificate. A quotation says only “3.1 certificate available.” The quantity, drawing and offer are invented for this example.
Mark the document difference in the comparison sheet. Ask the supplier whether the requested scope can be provided, with the validation arrangement and document timing stated. Keep the quotation unresolved until the responsible buyer has a usable answer.
| Fictional offer entry | Buyer’s clarification |
|---|---|
| “Certificate included” | Which document type and item does this cover? |
| 3.1 offered; 3.2 requested | Confirm the requested scope or identify the unresolved deviation. |
| Document after shipment | Agree when the buyer will receive the evidence needed for release. |
| Multiple material lots | Explain how each supplied group will connect to its documents. |
Do not replace the requested wording with the seller’s wording merely to make the two columns match. Preserve the original requirement and the proposed response. If an alternative is approved, keep the named approval and revised order together.
A request for a document change should remain a supplier question until the proposed process is explained. Adding a different number to a PDF title does not answer who will validate it or what the underlying evidence covers.

Check 3: agree the results and keep the material connection readable
Give the supplier the applicable material and order references. Ask which results will appear in the proposed document and how they relate to the supplied item. Have the responsible reviewer resolve any difference between the requested evidence and the offered evidence.
Keep a simple index beside the order: line item, supplied material identity, document reference and review status. Use the actual supplier’s identifiers. Do not invent a heat or batch number to fill an empty cell.
If the delivery contains several identified groups, keep their connections separate. A document covering one group should not be silently assigned to another because the stock looks similar. An unclear label belongs in the discrepancy record until it is explained.
For cut blanks, ask how identification will be retained through cutting and packing. The practical aim is for the receiving team to connect the delivered pieces with the agreed evidence without reconstructing the order from scattered emails.
The aluminum material certificate guide covers the wider document-reading task. Use the cutting traceability guide when planning how the stock record follows the parts through production.
Check 4: plan when and how the documents arrive
State the review point in the order. If your workflow requires evidence before material release, agree a handover that gives the reviewer time to use it. Record the contact responsible for answering a document query.
Retain the received document in its original form, along with any supplier clarification. A buyer’s note can explain the review status; it should not overwrite the issuer’s document or make an unresolved response look approved.
When a revised document arrives, retain the connection to the earlier version and the reason for the change. Tell the receiving and production teams which review is current. A revision matters only when the people releasing material can find it.
If the shipment arrives before a document issue is resolved, follow your established release process. Record the open question and its owner. This article does not prescribe a universal acceptance decision for every material order.

Ask a question the supplier can answer completely
Please confirm the inspection document type for order [reference and revision], line [item]. Identify the proposed validation arrangement, the results covered and the connection to the supplied material. State when the document will be available and highlight any difference from our requirement before order confirmation.
Attach the relevant requirement instead of asking the supplier to infer it from a shorthand email. Keep the response beside the quotation, then carry the agreed wording into the confirmed order.
When requesting aluminum cutting equipment, explain how your incoming-material records will connect to the cutting and packing workflow. Discuss your stock and cut-part identification needs with JiurunCut. Include a representative part drawing and the document handover you want to maintain.
