Why is calibration important?

Test equipment monitoring is specified as an essential element of quality assurance for standard calibration in accordance with the DIN EN ISO 9000-9004 series of standards. Test equipment monitoring must assure that all test equipment used for assuring product quality measures “correctly”.

In order to ensure that this is the case, test equipment must be calibrated on a regular basis, and must be retraceable to national standards. Obtained measured values must be documented as well. Retracing of calibration results to national standards has been confirmed for the user in the past by means of a "factory certificate" provided as a standard feature.

However, international recognition of certificates of this type has become more and more uncertain due to rapidly growing numbers of, in some cases unqualified, calibration service providers. For this reason, ISO9000 inspectors are not only demanding calibration certificates from EA accredited or associated calibration service (European Cooperation for Accreditation) in European countries outside of Germany.

International memberships

DAkkS is a member of the international accreditation organisations European co-operation for Accreditation (EA), International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC).

DAkkS international network activities
DAkkS represents German interests at the General Assemblies and committees of EA, ILAC und IAF and assumes important positions in these international accreditation organisations. It fulfils this function in coordination with the accreditation advisory board.

In addition, DAkkS also supports the "peer evaluation process" of the EA and is active in the development of new documents and standards on an international level. In this vein, DAkkS makes an important contribution to the acceptance of the German conformity assessment system.

Mutual recognition of accreditations

A key objective of the international accreditation network is the mutual recognition of the services and results of accredited bodies in order to prevent technical obstacles and multiple accreditations.

This is made possible by multilateral agreements and treaties (MRA or MLA) between the national accreditation bodies and the international accreditation organisations. It creates both national and international recognition that e.g. each laboratory accredited by DAkkS is able to conduct certain testing or test types or calibrations in a competent manner.

DAkkS is a signatory to the following agreements:

  • EA Multilateral Agreement (MLA)
    The European Cooperation for Accreditation is the unifying organisation for European accreditation bodies.
  • ILAC Mutual Recognition Arrangement (MRA)
    The International Laboratory Accreditation Cooperation (ILAC) is the global association for the cooperation of accreditation bodies for calibration and testing laboratories.
  • IAF Multilateral Recognition Arrangement (MLA)
    The International Accreditation Forum, Inc. (IAF) is the global network of accreditation bodies that provide accreditations for products, management systems and persons.

Our Calibration Center is accredited per DIN EN ISO / IEC 17025 as a DAkkS Calibration Lab under No. D-K-20313.

This assures that all requirements regarding service provider expertise are adhered to.
Personnel assigned to DAkkS laboratories are subjected to examination for adequate capabilities and skills, and are continuously monitored.
Beyond this, technical standards such as measuring uncertainty are known, and can be published as well.
