Calibration

Measure correctly and keep your customers happy!

If you use measuring equipment in your work, you surely know how important it is that it provides accurate readings and that you and your customers can trust the results shown by, for example, the testing equipment.
When you calibrate testing equipment, you get clear, objective confirmation of how accurately the equipment actually measures. Calibration is about quality assurance and reliability. In technical contexts, decisions are almost always based on test results in one form or another. Correct decisions therefore require reliable test results. Decisions made on incorrect grounds can, for example, lead to faulty designs. Without accurate measurements (traceable calibrations with stated measurement uncertainty), the company risks lower quality, reduced competitiveness, and ultimately poor profitability.

If you want suitable and reliable testing equipment, you can ensure this by having it calibrated regularly through our accredited facility (SS EN ISO/IEC 17025). ZRS Testing Systems AB can provide traceability and report measurement uncertainty.

All measurements are subject to certain measurement errors. These factors may be due to:

• the measurement accuracy of the sensors used
• selection of measurement area
• reading error
• environmental stability, such as temperature fluctuations, vibrations, and dirt
• the design and uniformity of the test bar
• the speed of the tensile test

Calibrate regularly—that way, you'll avoid problems!

If you want to ensure the accuracy of your measurements, one step in the quality chain is to regularly calibrate your measuring instruments, thereby maintaining control over their impact on the measurement. The ISO 7500 standard for force calibration and the ISO 9513 standard for strain calibration recommend that calibration be performed at 12-month intervals. Many sources of error can be eliminated by using proper measurement methods as well as the correct type of instruments and transducers. You must also be aware of the instrument’s measurement error; otherwise, it may ultimately contribute to quality defects in the products or services to be delivered.

ZRS Testing Systems AB is an accredited calibration laboratory in accordance with the ISO 17025 standard. This means that we have written procedures that describe how calibration work is to be performed and how our customers are to be treated. This ensures that we follow the same procedures every time. SWEDAC regularly reviews our procedures to verify that they are effective and that our work is performed correctly in accordance with established standards. This means that SWEDAC inspectors visit us regularly and accompany and monitor us during on-site calibrations at customer locations.

SWEDAC’s audit is an important part of ensuring that we are doing things right. There are also other important factors to consider, such as the fact that the equipment we use when calibrating your machine is highly accurate and of the highest quality. The equipment is traceably calibrated to international standards, and we use special adapters that ensure the best linearity and, consequently, the highest measurement accuracy. ZRS calibration technicians receive ongoing training in performing calibrations and service. They also regularly participate in interlaboratory comparisons to ensure their competence. The sooner you detect errors in your production, the less expensive it can be to correct them. You should know whether the product meets the required quality standards as early as the manufacturing phase.

ZRS Testing Systems AB’s calibration services provide greater peace of mind for you and your internal and external customers. Through our accreditation, we have demonstrated our expertise both in Sweden and internationally.
