ISO 22688 "Quality requirements for brazing of metallic materials" is a guide providing complete sets of quality requirements, both in workshops and installation sites, of any sort of brazed construction or product.

In order to ensure the required quality level for brazed products and to optimize manufacturing costs, the entire brazing production process must be controlled starting from the arrival of the materials in the workshop. To take into due consideration all the different factors that can affect quality, the manufacturer must implement a quality assurance system. The ISO 22688 standard defines the requirements that manufacturers must meet in order to operate in accordance with the criteria of good manufacturing practice.

IIS CERT is accredited to ISO IEC 17021 and ISO IEC 17065 by ACCREDIA for the certification of companies in accordance with ISO 22688.

The ISO 22688 standard, "transversal" to the various production contexts, finds its most suitable application in combination with multiple product standards. Among them:

  • EN 14276 -1/2 for pressure equipment for refrigeration systems and heat pumps
  • EN 13445 for pressure equipment - Containers
  • EN 13480 for pressure equipment - Piping.

>> Benefits
In contractual situations: for the definition of brazing requirements; as a guideline for the verification / qualification of suppliers of brazed products>

  • for manufacturers: in defining and maintaining quality requirements for brazing
  • in quality management systems: as a guideline for the management of the brazing “special process”; as an integration of ISO 9001
  • in the context of European directives (PED, Simple Containers).

Companies certified by IIS CERT in accordance with ISO 22688 are included:

  •  in the List of Certified Companies published on our website
  •  in the List of Certified Companies published on the Accredia website (Accreditation body of certification bodies).

>> Related activities
In order to implement a proper management of the brazing process, the manufacturer must have adequate and competent personnel to supervise, inspect, test and control the production in accordance with the prescribed requirements as well as prepare specific activities.
