Proficiency tests and comparative measurements

You can fully trust our experts in the field of metrology to perform proficiency tests and comparative measurements. We can overcome any of your challenges and ensure that your measurement procedures are valid.

Testo Industrial Services is an accredited provider of proficiency testing in the thermodynamic and dimensional environment according to DIN EN ISO/IEC 17043:2010.

Comparative measurements can additionally be carried out in a non-accredited framework according to the current service portfolio of Testo Industrial Services.

Proficiency tests and comparative measurements are usually to be performed as interlaboratory comparisons with several participating laboratories. In addition, Testo Industrial Services also offers the possibility of completing individual bilateral comparisons. Here, the task description and the time of execution are variable, coordination with of our metrology experts is required, please feel free to ask us.

Eignungsprüfungen als Ringvergleich

Proficiency tests as ring comparisons

Testo Industrial Services offers proficiency tests as ring comparisons/ring tests. Within such ring comparisons/ring tests, a specific measurement or test task is carried out by a group of laboratories independently of each other and one after the other. There are ring-shaped and star-shaped forms.

Eignungsprüfungen als bilaterale Vergleiche

Proficiency test as bilateral comparisons

In a bilateral comparison, two laboratories are compared with each other, the pilot laboratory and the requesting laboratory. The advantage here is that the requirements of the laboratory can be customised to a certain extent. In addition, the implementation time is usually shorter compared to a ring comparison.
