How to Avoid Bonded Joints Failure – DIN 2304-1 Explained

Last update on Jun 30, 2017

Quality Requirements for Adhesive Bonding Technology

Due to the multiple, well known advantages of adhesive bonding together with the numerus successful examples from industrial to handicraft applications adhesive bonding is considered as an innovative and reliable joining technology.

The adhesives offered by adhesive manufacturers for industrial use are typically high-quality products manufactured in compliance with standards in so-called managed processes. Providing a correct use of the adhesives a zero fault production of bonded parts is realizable. This has been proven by many successful applications in different industries as well as in handicraft.

Unfortunately, in some cases - but still all too often - bonded joints do fail during the usage phase. Only in very rare cases, a defect in the adhesive itself has been identified as root cause. In most cases (>90%) an incorrect use of the adhesive, mainly derived from a lack of bonding knowledge was identified as root cause.

This calls for a need of a regulatory standard for defining quality requirements for adhesive bonding processes. Let's understand how DIN 2304-1 is serving the purpose.
