DIN EN ISO/IEC 17025-certified calibration standards from Fischer
Since 2003, the Deutsche Akkreditierungsstelle GmbH DAkkS (German Accreditation Body) has certified our calibration laboratory as a "competent calibration laboratory": Helmut Fischer GmbH's calibration laboratory is the first and only company in Germany to be accredited according to DIN EN ISO/IEC 17025 for the mechanical measurand "mass per unit area". This means: Our standards are measured, calibrated and certified with the highest quality, precision, care and proven measurement uncertainty. In addition, the accreditation guarantees the complete traceability of the standards to national standards. You can rely on our certified values at any time and in any place - regardless of the measuring device you use or the method you apply!
At Fischer, you get full measurement expertise from a single source: in addition to our comprehensive portfolio of XRF analysers and services, we have around 500 certified calibration standards permanently in our range. With us, you will find the right solution for almost any measurement task.
Meaning and importance of traceable standards
A measured value is metrologically traceable if it can be related to a recognised standard through an unbroken chain of comparative measurements (calibrations) with known measurement uncertainty. In accordance with ISO 17025 accreditation, this chain must be mapped down to a national standard or an SI unit. All Fischer standards with a DAkkS calibration certificate have a defined, individually determined measurement uncertainty and are directly related to a national standard. This means that the measured values are absolutely reliable and comparable regardless of the method, device and location used. This has a high practical relevance in the context of audits and in assessments for standards.
In-house production and in-house certification
The Fischer calibration laboratory is not only responsible for the certification of standards and normals, but also for their manufacture. In this way, we can ensure and promise that the materials meet the highest standards of quality and homogeneity necessary for a reliable standard and are processed accordingly. With us, you get the calibration standard that is optimally suited to the measuring instrument used, whether it is a hand-held measuring instrument or an XRF spectrometer. In-house production of both the standards and the measuring instruments ensures you will always receive the right standard for your measuring task!
We make it possible: Your sample as a certified standard
Benefit from your customised calibration standard and have your sample certified as a calibration standard by our measurement experts. In addition to in-house produced, certified standards, Helmut Fischer's calibration laboratory also offers ISO/IEC 17025 certification of specific customer material. So you can use your workpieces for process control, quality control or development - thanks to the DAkkS calibration certificate! Contact us and we will be happy to advise you on your individual customised solution.
Not everyone can become a DAkkS laboratory
In order to obtain accreditation according to DIN EN ISO/IEC 17025 of the DAkkS, very strict guidelines must be followed and a corresponding quality management system must be implemented. With each DAkkS calibration certificate, we literally certify compliance with these rules. The requirements include specifications on the competence of the personnel, quality, precision, diligence, quality as well as a proven measurement uncertainty of the measurements and standards. Equally important is the complete documentation of results and processes, as well as the proof of a clear traceability of the standards to national norms.
Experts for your measurement precision
The calibration laboratory team consists of 12 scientists who are specially trained in the various calibration measurements. What all Helmut Fischer employees have in common: quality awareness, care, precision and reliability are top priorities. A separate department within the laboratory ensures the controlled handling of the measuring instruments, measurements, standards and documentation, and ensures that certifications are carried out in accordance with our accreditation.
The right environment matters
In the production of certified calibration standards, it is essential to have constant conditions for calibration measurements. The laboratory therefore has climate-monitored measuring rooms with a constant, controlled and documented temperature and humidity. The FISCHERSCOPE XRF analysers in the laboratory provide optimum performance in the measurement and calibration of standards and working standards.
