ZwickRoell stands for reliable test results

To keep up with fast-paced technological advances, developers and engineers are continuously trying to push the boundaries of physics to develop new and improved materials. At the same time, globalization is leading to international supply chains and spatial separation of research and production sites. Consequently, it is imperative for quality assurance and R&D departments that test results be accurate, repeatable, reproducible and traceable – in one word, they have to be reliable.

Reliable test results are a fundamental and hot topic in materials testing. With each materials and components test we ask the same questions:

Is the value obtained truly accurate?
Are the results repeatable?
Are these results comparable to other measurements?
Is it possible to determine who, when, how, and what happened?
And finally, does the measuring equipment meet the required standards and specifications?

ZwickRoell and our machine and software solutions stand for accuracy, repeatability and reproducibility, as well as seamless result traceability of determined results.

Accuracy

Our machines are accurate and the determined measurement results are always very close to the reference value.

Repeatability

Repeated tests under the same conditions produce the same achieved results.

Reproducibility

Tests performed on various ZwickRoell machines/solutions produce reproducible results.

Traceability

Continuous documentation of calibrations and tests provides transparent and traceable results.

Engineering "Made by ZwickRoell" – quality from a single source

To us quality means: we meet all of your requirements. Without if or but. Regardless of complexity. We are able to achieve this with our flexible and well-designed machines, and with our "Made by ZwickRoell” quality standard.

We develop and manufacture all materials testing machines ourselves at ourproduction facilities. This includes mechanic, electronic and software components as well as the wide range of accessories. By doing this we are able to perfectly match our components to each other and meet our quality standards. This also allows us to provide the highest level of support.

We are at home all over the world: As one of the world's leading suppliers of materials testing systems, we are represented by subsidiaries and sales partners on all continents. This provides our customers with excellent local service and personal consulting in over 56 countries with a calibration network that is certified worldwide.

We support you throughout the entire life cycle of your testing systems with customized services. For our materials testing machines we guarantee the availability of spare parts for at least 10 years after a product has been discontinued. In short: when you choose us, you choose absolute investment security.

Safety for the complete testing system

Integrated safety in accordance with the EC Machinery Directive

The highest degree of safety for user and testing system is guaranteed. All EC Machinery Directive safety requirements are guaranteed. Compliance is documented with an EC Declaration of Conformity. State-of-the-art safety technology and proven industrial components that comply with the highest safety and industrial standards (IEC 60947) are used.

Safety for the complete testing system

The highest level of safety is achieved with a two-channel safety circuit, which includes the crosshead travel limit switch, drive Off switch, motor break function and the operation mode switch. Relevant accessories are also tied into the safety circuit. The CE-compliant safety device with electrical interlocking and mechanical guard locking prevents interference with the machine during the test.

Ready for the Next Generation

Modular design means that the testing system can be reequipped or upgraded whenever required. Moreover, testControl II machine electronics are compatible with future-generation ZwickRoell software. Even after a product has been discontinued, spare parts remain available for a minimum of 10 years.

User Safety

Intelligent safety functions, industrial safety technology, selectable operating modes and compliance with the new EC Machinery Directive all come together to ensure maximum safety for the user.

Data Security

ZwickRoell's testing software guarantees maximum security for user data and test results. Tamper-proof test results are ensured through, among other things, the following testing software functions:

Comprehensive user management feature, which can reduce user input options to a minimum;
Traceability of all test- and system-relevant data;
Precise repeatable test conditions with the system configuration builder;
Targeted test configuration through the intelligent wizard.

Specimen Safety

Active sensor monitoring, force limitation during setup mode plus intelligent force increase detection and force zero control in ZwickRoell’s testing software safeguard the specimen against unacceptable overloads.

System Safety

The intelligent sensor identification system in combination with the system configuration builder prevent damage to the testing system if limit values are exceeded. In addition, the new system monitor enables total supervision of key system status indications and offers preventive advice.

System Monitoring

testControl II system monitoring provides the user/laboratory manager with detailed information on the current status and level of utilization of the testing equipment. This enables further increases in testing equipment availability and greatly simplifies maintenance planning and spares/replacement procurement.

Innovation Through Research

Since 2014, the Stiftverbund (German Sponsors Association) has recognized research companies for the responsibility they assume for their country and society with the seal "Innovation through Research."

The Stiftverbund is one of the largest private research funders in Germany. In addition to its commitment to the next generation of academics, excellent institutes of higher education and advanced research, it also responsible for examining and evaluating German research and innovation systems. How much does the economy invest in research and development in Germany? What impact does this have on the future of this country? These questions are the focus of the R&D survey which takes place annually on behalf of the Federal Ministry of Education and Research.
