Benefit from our many years of experience in calibrating testing systems at Germany's biggest testing laboratory.
Our calibration service and laboratory have been accredited by the German Calibration Service (DKD) since 1994 and DAkkS-accredited since 2013. This shows that we clearly satisfy the requirements for testing and calibration laboratories as defined by DIN EN ISO/IEC 17025—your guarantee for accurate, independent, and efficient calibration services.
ZwickRoell in North America is accredited to A2LA for calibrations as outlined in our certificate below.
We are experts in many calibration methods, covering numerous standards. Our comprehensive materials testing machines and instruments calibration portfolio enables us to calibrate a wide variety of measurands. This includes accredited measurands such as force, length, mechanical work and hardness, plus many additional measurands so that we have the right solutions readily available for your machines and requirements.
Static or dynamic materials testing machines, pendulum impact tests, hardness testers or other testing machines—we can provide professional, traceable calibration for all. In addition to our own ZwickRoell materials testing machines and instruments, we can also calibrate testing machines made by other manufacturers.

What sets us apart
The range for calibration depends on the type of load cell on the materials testing machine, the machine electronics, and the display resolution. For ZwickRoell materials testing machines with high precision(HP) series load cells, the range is starts at 0.2% of nominal force; for other types the range starts at 0.4%. In this way we cover the full measurement range and ensure maximum result accuracy. The standards require a calibration range of 20 – 100% of the nominal load and five calibration stages. A ZwickRoell calibration certificate consists of 11 calibration stages.
As part of our calibration service, we offer inspections carried out using checklists to reduce the risk of malfunctions or machine downtime and guarantee productivity. This means you save money on repair costs and spare parts in the long term. During these inspections, which only we as manufacturers can perform, our service technicians inspect your testing machines and are able to carry out minor repairs and adjustments on the spot. This inspection is especially important, since the normative directives DIN EN ISO 7500-1 specify the need for inspection prior to calibration.
