German to English Tech/Engineering Engineering (general) Meeting Minutes

"- Hinsichtlich des Produktes ABC wurde von Herrn X das Problem aufgeworfen, dass in Dänemark aus unterschiedlichen ***Prüfzentren*** unterschiedliche Ergebnisse hervorgegangen sind und dies Probleme auf dem Markt mit sich bringt."

From the minutes of a meeting about a company that makes technical products (plasters, cleaners etc.). Hence my classifying it as a Tech/Engineering question and not a Bus/Financial one.

For some reason, no dictionary seems to have heard of Prüfzentrum. I find this truly bizarre, as the word is in frequent enough use. I often see it in medical contexts, where it tends to mean something like "trial site". But here a cleaning product is being referred to, so this involves testing a technical/chemical product rather than a medical drug.

There are one or two "obvious" solutions, but I don't trust obvious solutions (although sometimes the obvious solution is actually the correct one!). "Test centre" seems to be used more in academic contexts than medical or technical ones. "Testing centre" is perhaps OK and does seem to get a goodly number of hits. But I would like to be absolutely certain, and it's about time the KOG did what the dictionaries are failing to do and provide a proper translation for this word! TIA for your help.
