Calibration and recalibration service from the Hoffmann Group

Accredited calibration (DAkkS/BELAC calibration certificate):

Accredited calibration laboratories are linked directly to national standards by means of reference standards. DAkkS (Deutsche Akkreditierungsstelle or German Accreditation Body) and other European accreditation bodies assess, confirm and monitor the professional competence of these bodies as independent institutions. We ensure processes are reviewed on a regular basis and implement our calibration processes properly in terms of measurement, which means you can rely on your measuring results.

In addition to German accredited calibration laboratories, we also cooperate with e.g. Belgian accredited calibration laboratories so we can also issue the certificate of the Belgian accreditation body (BELAC certificate) in exceptional cases.

Thanks to multilateral agreements concluded by the ILAC and the EA and the accreditation bodies of the various countries, the DAkkS calibration certificates and BELAC calibration certificates are internationally recognised, valid and audit-proof. This avoids the need for costly multiple accreditations.

Advantages of accredited calibration:

• Utmost reliability and the highest standard below national standards
• Valid/recognised internationally
• Subject to state regulation
• Can be traced back to national standard directly
• Mandatory for all companies in the automotive industry and its suppliers in accordance with the IATF 16949:2016 standard

Factory (ISO) calibration certificate

Factory calibration is a cost-effective alternative to accredited calibration (e.g. DAkkS). It can be traced back to the factory standard (not to the
national standard as with an accredited certification) and meets the required standards in many areas.

Our calibration partner’s laboratories always work in accordance with DIN, which ensures that the calibration and samples can be traced back whilst meeting the highest standards.

Advantages of factory calibration:

• Attractively priced
• Quick
• Can be traced back to national standard indirectly

An accredited calibration is necessary when the result of the calibration must be traceable to the national standard and be recognised on an international level. Furthermore, since September 2018, IATF 16949 prescribes DAkkS calibration for manufacturing activities in the automotive sector.

It is usually up to the Quality Management department in a company to determine how often a measuring tool should be calibrated. As well as using cycles or frequency of use to determine the time of recalibration, it is advisable to have measuring tools calibrated after incidents, e.g. if they have been dropped.

With more than 780 accreditations worldwide in 28 measurement variables, Trescal has a unique portfolio of accreditations.

All laboratories adhere to the standard in accordance with DIN EN ISO/IEC 17025 without exception. This ensures that the calibrations can be traced back. Since quality is top priority for Trescal, the quality management systems are based on DIN EN ISO 9001 and DIN EN ISO/IEC 17025.

In future the calibration certificates will be made available digitally. You can call up all your calibration certificates in digital form whenever you like in Connected Metrology Free. You only need to register once at the start and you will then have access to your calibration certificates at any time.

The calibration certificates are stored by Hoffmann for at least 10 years.

Due to the increased requirements of the GDPR (General Data Protection Regulation) and customer requirements, we will in future pass on to external service providers only the most important customer data which is required to provide the service. For this reason, all calibration certificates are issued to “Hoffmann Supply Chain GmbH, Poststr. 15, 90471 Nuremberg”.

This calibration certificate will include an information sheet containing the key information such as customer address, calibration certificate number, overall result, image and product data, so that you can view all relevant information at a glance.

We do not charge a processing fee. In exceptional and urgent cases you can also send us a small number of units. In general, however, measuring tools should be grouped for recalibration.

The assignment of a serial number using a data matrix code (adhesive sticker) is free of charge.
Additional customised labelling must still be paid for.

We provide the Hoffmann Group system boxes free of charge. If you already have this system box, you can also use it to send measuring tools. The Hoffmann Group system box is free for you. We do not require any loan fees.

The goods will be collected from you free of charge within 24 hours. The return delivery after calibration has been performed is free of charge from a net order value of 250 euros.
