The DIN 2304 is based on the ISO 9001.
Independently of the fact that the reputation of the ISO 9001 has suffered in the industrial sector, its basic concept remains ingeniously simple:
If the production phase of a finished object – or its eventual defects – cannot be verified without carrying out a non-destructive test, it undoubtedly signifies that a so-called “special process” is involved.
On the basis of the assumption that the adhesive is a high quality product, which if used correctly enables the creation of a “zero error” product, this simply implies the need to exclude all errors during the manufacturing process of the finished product.
Consequently, the ISO 9001 quality management system (QMS) aims – as much as possible – to prevent and exclude every error in application.
For “special processes”, the identification profile is “Error prevention”, achieved by carrying out an effective SGQ process.
This concept has long been adopted in the field of welding, and has now been extended to more recent bonding technologies.
