Calibration

Relevant Information of the DAkkS

The calibration laboratory is accredited by the Deutsche Akkreditierungsstelle GmbH (DAkkS)

in accordance with DIN EN ISO / IEC 17025 and has the competence to carry out calibrations for measurand temperature, dew point temperature, relative humidity, temperature and climatic test cabinets, including on-site calibrations.

Regulations of Deutschen Akkreditierungsstelle (DAkkS) on metrological traceability

Under the DAkkS’s new regulatory framework, the previous rules are being phased out gradually. The current regulation governing the accreditation of calibration laboratories in accordance with DIN EN ISO/IEC 17025:2018 is R-17025-K. This regulation specifies the requirements of ISO/IEC 17025 regarding metrological traceability (6.5).

Calibration certificates from accredited calibration laboratories without the accreditation symbol (Factory calibration) are not recognised as proof of traceability.

Our clear recommendation is:
• If you require a calibration certificate as proof of traceability, please avoid unnecessary effort and opt for proof of traceability based on a DAkkS calibration certificate. This is undoubtedly recognised internationally and offers the greatest possible assurance. This is attributable to multilateral agreements on the mutual recognition of accreditation systems, which the European umbrella organisation European Cooperation for Accreditation (EA) has concluded with the International Laboratory Accreditation Cooperation (ILAC).

DAkkS calibration certificates are audit-proof and provide you with legal protection in the event of a product liability claim.

• For you, technical information about the item being calibrated is the priority. Can you rule out the need for a traceability certificate? If so, our more cost-effective factory calibration certificates are an alternative for you. We guarantee that our factory calibrations are carried out with the same level of expertise as our DAkkS calibrations. We do not offer second-class calibrations.

CTS GmbH recommends DAkkS calibration certificates.
Outside the scope of accreditation, we also offer factory calibrations (WKD).

Frequently asked questions

Within the system of the German Calibration Service (DKD), calibration laboratories of industrial firms, research institutes, technical authorities and inspection/testing institutions carry out calibration work. These laboratories are accredited and supervised by the accreditation body of the Deutsche Akkreditierungsstelle GmbH (DAkkS).

Calibration is the determination of the interrelationships between the stated values of a measuring instrument (measuring device/material measure/material measure/value of a reference material) and those values determined by exact standards. The calibration certificate contains the measured value including the specification of the respective measurement uncertainty. If necessary it can be stated if a tolerance limit is observed or not.

DKD calibrations are carried out for measuring instruments, reference materials and material measures for the measurement categories and ranges specified within the framework of the accreditation. DKD calibration certificates issued are proof of measurement traceability to national or international standards as required in the family of standards DIN EN ISO 9000 and DIN EN ISO/IEC 17025.

This is a procedure used by an authorized body (the Deutsche Akkreditierungsstelle GmbH (DAkkS)) to issue formal acknowledgment of the competence of a body or a person to fulfill certain tasks.

Calibrations carried out by DKD laboratories allow the user to trust the reliability of measurement results. They increase customer confidence and competitiveness on national and international markets. They also serve as a technical measurement basis for the control of measurement and test equipment within the framework of quality management.

Standard (VIM): "Material measure, measuring instrument, reference material or measuring system intended to define, realize, conserve or reproduce one unit or one or more values."

A standard which has been approved by national decision of a country as the basis for the determination of values of all other standards of the respective measurement (SI unit).

A standard, generally of highest available accuracy (at a given place or at an organization), from which measurements carried out (there) can be derived.

It is the procedure of tracing measurement results by an unbroken chain of calibrations to the national standard and thus to the respective SI units.

A number of activities, always including a visit to the laboratory in addition to a review of documentation (carried out at regular intervals by the Deutsche Akkreditierungsstelle GmbH (DAkkS)), in order to ensure that the accredited laboratories work according to the accreditation criteria. The interval between initial assessment and (complete) reassessment is 5 years.

Fulfilment of determined requirements by a product, a process or a service. The statement of conformity may only relate to measuring technology, compliance in the context of measurements performed can be found and witch are identified, e.g. by specifying the exact section of a uniquely standard or a policy. The statement of conformity must be based on measurement for the calibration laboratory is accredited.

An experimental procedure in which a specific value of a physical quantity is determined as a multiple of a unit (or of a reference standard).

A physical quantity recorded by measurement (e. g. density, length, mass, current, temperature).

Parameter assigned to the measurement result, characterizing the dispersion of values (reasonably) capable of being assigned to a measured.

Please refer to www.dakks.de for more detailed information.

Accreditation of DKD laboratories is based on the rules and procedures of the German Calibration Service (DKD) as defined in DIN EN ISO/IEC 17025. Due to amendments in the standard (version 08/2005), all laboratories will undergo assessment for compliance to the amended version of the standard by 15th May 2007 within the framework of monitoring visits.
