3.1 and 3.2 approval

Certificate 3.1 and certificate 3.2 are documents of the same series, although they have minor differences. Find out what distinguishes both certificates and what they have in common.


What is a 3.1 acceptance certificate?


The 3.1 inspection certificate is a declaration of the manufacturer (producer), in which he confirms that the products delivered to the customer comply with the requirements specified in the order. The document is issued together with the results of the tests that were carried out during the specific inspection. The method of performing the tests depends on the applicable official regulations, technical regulations or is described in detail in the product specification. The document can be signed by an authorized representative of the manufacturer’s control, who is independent from the entire production department. European Standard 10204 allows the test results from the acceptance control of raw or pre-processed input materials to be attached to the certificate.


3.2 acceptance certificate and inspector’s inspection


The 3.2 certificate is a statement in which, in addition to confirming that the products comply with the customer’s order, the test results from the inspection carried out by the ordering party’s representative or the inspector of the Office of Technical Inspection (UDT) are attached. These people are responsible for confirming that the entire production process of the ordered batch of goods in which they participate is in accordance with the requirements specified in the order.. The 3.2 certificate is a control document which guarantees that the products delivered to the customer comply with the requirements specified in the order and the test results are attached to them.

Specific quality control

During the specific quality control, the guidelines set out in the product specification are followed, strictly adhering to the agreed delivery conditions or on the basis of official and technical regulations. The inspection documents confirm that the delivered products comply with the agreements and terms of delivery provided by the customer when placing the order.

Acceptance certificate 3.1 and 3.2 according to EN 10204


Who is authorized to confirm the acceptance certificate?


According to the European standard 10204, certificate 3.1 may be issued by the manufacturer (manufacturer). The required documents are handed over to the client along with the test results. The manufacturer also states that the delivered products are in accordance with the order. On the other hand, the 3.2 certificate may be issued by an authorized representative of the manufacturer who, at the same time, cannot be associated with the production department in any way. In accordance with EN 10204, certificate 3.2 may also be issued by a control inspector or the contracting authority’s control representative.


Is it allowed to copy documents?


The authorized representative is obliged to provide the relevant documents in the original or in the form of a photocopy. EN 10204 allows original documents to be copied when two conditions are met. The first is the application of the traceability procedure. They are related to the product labeling (identification) system in such a way that it is possible to identify each batch of the product. The second condition is that the original document is made available upon request.


Is the issue of certificates payable?


A common question is: is there a fee for issuing additional certification? Short answer: yes, both documents are payable. It is worth adding, however, that declaration 3.2 is more expensive. This is due to the fact that the quality control is carried out by an inspector, e.g. UDT, an independent representative of the manufacturer or a representative of the contracting authority. One of these people is present throughout the entire production process. This is to state that the order is being carried out in accordance with the customer’s requirements. The broker (authorized representative) provides the complete set of documents (copy or original) to the client.

The EN PN 10204 standard prohibits the document issued to the customer from containing any changes. In most cases, also explanations of the product traceability procedures should be provided
