The final piece needed to provide a universal benchmark for comparing the accuracy of ESPI measuring machines was certification under the ISO 10360 protocol. This is now a reality. We are proud to announce a maximum permissible error (MPEe₀) of:

​2 µm + L / 300

*Applicable to all our Scanflash TC G2 models with TP200

What is the ISO 10360 standard?

For those not yet familiar with this standard, ISO 10360 defines the testing and verification methods for the accuracy of coordinate measuring machines (CMMs). It provides an objective way to assess and compare the metrological performance of machines based on internationally recognized standardized procedures.

In practical terms, this standard ensures that the measurements performed by our machines are reliable, repeatable, and traceable under real operating conditions.

Why does this certification matter?

Our machines are known for their exceptional speed. This performance can sometimes raise questions: is it really possible to combine speed with metrological precision?

The ISO 10360 certification provides the answer to that question.

It is an objective and measurable proof of the accuracy of our machines, validated according to a rigorous international protocol. It demonstrates that even at high speeds, our systems fully comply with the most demanding performance standards.

With this certification, you are guaranteed that your ESPI machine:

• meets international standards for accuracy,
• delivers reliable and comparable results, regardless of the production pace,
• meets the requirements of industries where tolerances are measured in microns.

It is an additional mark of confidence, confirming the strength of our metrological approach.

MPEe₀, a key indicator of accuracy​

The ISO 10360 standard defines several performance criteria, including MPEe₀ (Maximum Permissible Error).

This indicator represents the maximum permissible error when measuring lengths, evaluated from tests performed with reference standards. In practical terms, it expresses the maximum deviation from a known value that the machine may show during linear measurements under controlled conditions.

The MPEe₀ is expressed as a fixed constant (in µm) combined with a value proportional to the measured length (L). This combination reflects both the machine’s intrinsic accuracy and its stability over increasing dimensions, ensuring reliable measurements across the entire working volume.

It’s also one of the first values metrologists look at when comparing different machines. Its standardized and easy-to-read format allows for an immediate assessment of the overall accuracy level and helps position the machine within demanding industrial contexts.
