October 2024: New accreditation certificate
Following a successful assessment, our new accreditation certificate with extensive extensions in the field of length measurement technology has arrived. In addition to the accreditation of our newest location in Heidenheim, the extensions also concern our other laboratories throughout Germany and our on-site services.
In addition to the expansion of our location in Heidenheim and the expansion of our measuring ranges, we were also able to integrate the accreditation for prismatic workpieces with coordinate measuring machines into our headquarters in Kirchzarten and into the partial certificate D-K-15070-01-01.
We have briefly summarized the most important innovations here:
- Accreditation of manual measuring equipment, gauges and dial gauges
- Accreditation for prismatic workpieces via coordinate measuring machine (CMM)
- Calibrated measuring volume of
X = 700 mm
Y = 1400 mm
Z = 500 mm
- Calibrated measuring volume of
With the integration of our service center in Villingen-Schwenningen into our headquarters in Kirchzarten, we have also moved the accreditation for prismatic workpieces with coordinate measuring machines (CMM) and integrated it into the certificate D-K-15070-01-01.
- Calibrated measuring volume of
X = 3000 mm
Y = 1200 mm
Z = 900 mm
- Extension of setting rings up to 300 mm at the Kirchzarten site
- Expansion of strip gauges up to 100 m and scales up to 3 m at the Essen site, in accordance with normative procedures VDI/VDE/DGQ/DKD 2618 Sheet 8.2:2023
- Expansion of 2-line micrometers in our laboratories throughout Germany and on site
June 2024: New accreditation extension
Our new accreditation certificate with extension in the field of length measurement technology has arrived: With immediate effect, we are able to calibrate displacement sensors in a measuring range from 0 to 1000 mm with accreditation.
June 2023: New accreditation certificate
After a successful assessment, the time has come again: Our new accreditation certificate with extensions of the mechanical measurands as well as flow measurands has arrived. The extensions concern both our laboratories at our service locations in Germany and our on-site services.
With the new certificate we were able to extend our measurement ranges as well as to reduce measurement uncertainties, but also to have new calibration procedures accredited. Thus we are now able to calibrate your torque sensors up to 5 kNm accredited and this both in the laboratory and on site.
We have briefly summarized the most important innovations here:
Extensions in the measured variables force and torque
- Force
Reduction of measurement uncertainty to 0.05% vMW over the entire range
New procedure: Calibration of sensors according to DIN EN ISO 376:2011
- Torque
Calibration of small torques from 0.01 Nm for torque wrenches and torque screwdrivers according to DIN EN ISO 6789 -2:2017
Calibration of torque transducers up to 5,000 Nm according to DIN 51309:2022 in the laboratory and on site
- Small flow rates from 0.1 ml/min
- Large flows up to 340 m³/h with water
May 2023: New accreditation certificate
Our new accreditation certificate is here. The extensions concern thermodynamic, mechanical, electrical, analytical measurands and flow measurands. Here, we are not only expanding our laboratory in Kirchzarten, but are also bringing our locations and our on-site scopes up to date.
With the new accreditation scope, we are the first calibration laboratory in Germany to be accredited for various flue gases. In addition, we are also keeping an eye on the mobility shift towards electromobility and are expanding our measurement ranges in the electrical laboratory and reducing our measurement uncertainties.
We have briefly summarized the most important innovations here:
- Calibration of current transformers up to 4000 A DC with a measurement uncertainty starting from 20 ppm
- Extension of DC power measurement up to 1 MW
- Extension of AC power measurement up to 120 kW
- Reduction of the measurement uncertainty in the high frequency range with the reflection factor
- Comprehensive DAkkS calibration of ESD generators up to 30 kW and 120 A
- High voltage calibrations up to 10 kV at your site
We are the first calibration laboratory in Germany to be accredited for flue gas calibrations.
- Calibration of measuring instruments for combustion plants
- Reference gases: O2, CO, CO2, NO, NO2, SO2, H2S, CH4
Extensions in the measurands pressure, torque and acceleration
- Positive overpressure as well as absolute pressure with our primary standard from 0 to 400 bar starting at 25 ppm
- Acceleration up to 20 kHz and reduction of measurement uncertainty
- Small torques from 0.2 Nm
- Temperature calibration for block calibrations down to -100 °C including reduction of measurement uncertainties.
- Reduction of measurement uncertainties for calibration of loggers in temperature or climatic chambers
- Measuring range extension for calibration of thermocouples up to 1200 °C
Calibration of flowmeters for flowing gases with real gas (Ar, He, CH¬4, N2, CO2) in the laboratory and on site
February 2023: Harmonization of the accreditation certificate
With the receipt of the new certificate and the associated harmonization of the accreditation numbers, we have also adapted our DAkkS certificate paper.
In the future, you will find the DAkkS logo with the accreditation number D-K-15070-01-00 and the header text "Calibration and testing laboratory for electrical, mechanical, dimensional, thermodynamic, analytical and flow measurement quantities" on the DAkkS calibration certificates.
With harmonization you will also find all services of our individual service centers as well as on-site and mobile calibration laboratories within one certificate.
The only exception is our service center in Villingen-Schwenningen.
