DIN 2304 – The standard for adhesive bonding in industry and craft

Adhesives are reproducible quality products. Bonding errors in industrial bonding are largely caused by application errors. The standard DIN 2304 “Adhesive bonding technology - Quality requirements for adhesive bonding processes” / ISO 21368 “Adhesives - Guidelines for the manufacture of bonded structures and reporting methods suitable for the risk assessment of such structures” provides users from all areas of industry and trade with a system for mastering adhesive bonding processes across all process steps.

While EN 17460 / DIN 6701 applies to all bondings, adhesive classes and material combinations in the rail vehicle sector, DIN 2304 / ISO 21368 applies to all force-transmitting bondings in all other sectors where adhesive bonding technology is used, such as the automotive industry, boat and shipbuilding, the electrical appliances and electronics industry and the construction industry.

Both standards place greater responsibility on the user and define the binding state of the art in product safety law for the professional implementation of adhesive bonding processes. They define both the requirements for the quality execution of adhesive bonds and the organizational, contractual and manufacturing principles for the production of adhesive bonds.

The “DIN 2304 Evaluation Plan” reflects the requirements of the DIN 2304-1 standard and is the basis for auditing.

Issue, publication and use of certificates and certification marks

With successful completion of the certification process, the company receives a printed certificate. Furthermore, an entry is made in the so-called “DIN 2304 online register”. This is where all valid DIN 2304 certificates are stored in a central database that can be accessed via the Internet. Only the entry of the certificate in the DIN 2304 online register www.din2304.de is recognized as proof of certification and the scope of certification. This must be taken into account, for example, when checking supplier certificates.

Furthermore, all certificate holders also receive the right to use the certification mark within the scope of our sign statutes.
