Tech/Engineering - Metrology
German term or phrase: Testleck
Context:

"Die Dichtheitsprüfung verlangt ein hohes Maß an Genauigkeit und Reproduzierbarkeit, weshalb Dichtheitsprüfgeräte regelmäßig geprüft werden müssen. Um diese Qualitätssicherung wirtschaftlich durchführen zu können, ist eine Überprüfung der Geräte vor Ort unabdingbar. Mit Testlecks von HeMaTech werden die zyklischen Prüfungen der Geräte zum Kinderspiel. Unsere Testlecks lassen sich im Handumdrehen zusammen mit einem Prüflings einsetzen, bieten Ihnen serienmäßig verschiedene Anschlussmöglichkeiten und besitzen eine sehr hohe Genauigkeit. Zudem zeichnen das robuste und rostfreie Metallgehäuse sowie der am Eingang verbaute Filter zum Schutz vor Verschmutzungen eine hohe Langlebigkeit unseres Produkts aus."

"Der Arbeitsdruck des Massenspektrometers liegt bei < 10−4 mbar. In kommerziellen Lecksuchgeräten ist das Massenspektrometer immer auch mit einem Vakuumsystem kombiniert, das mindestens aus einer mechanischen Vorpumpe, einer Hochvakuumpumpe, Druckmessgeräten sowie einer Reihe von druckabhängig gesteuerten Ventilen besteht. Stand der Technik ist ebenfalls ein integriertes Testleck, mit dem das Lecksuchgerät kalibriert werden kann."

test leak / calibration leak / calibrated test leak
Explanation:
"Leak tests" would be the "Dichtheitsprüfungen" as such, but this is not what's meant here.

See, for example,

https://www.pfeiffer-vacuum.com/en/know-how/leak-detection/l...
"The leak detector must be calibrated in order to determine leakage rates. This is done using a commercial test leak, which generates a known and reproducible test gas rate under defined conditions. Commercial test leaks are available in the form of a permeation leak or a capillary leak with or without a test gas reservoir. Leak detectors are usually equipped with permeation leaks with a helium reservoir. For calibration, an appropriate working cycle is often built in that automatically performs the calibration."

agree  Björn Vrooman: Agree, though only under the condition you remove "test"; it's a calibrated leak. Ofc, it's used for testing (and no to test leak). ENS UK: https://www.ionscience.com/products/calibrated-leaks-2 US: https://www.uson.com/leak-testers/leak-masters

  -> Yes, "calibrated leak" would definitely be the most appropriate translation.
agree  Sangeeta Joshi: Though I too prefer the term calibrated leak.
