German term

Kugelmessmethode

German to English Tech/Engineering Aerospace / Aviation / Space aircraft hydraulics
The term "Kugelmessmethode" appears in the context of a requirement description for aircraft hydraulics.

Anforderungen an die Sonderstutzen
Fertigungs- und QS-Maßnahmen
Fertigung im unteren Gewinde-Toleranzbereich
*Kugelmeßmethode* zur Beurteilung der Dichtflächen
Sichtprüfung auf Grat- und Riefen¬freiheit

I am not familiar with this term or method and could not find meaningful results via google search.

Any pointers appreciated! Thank you.

@ Stefanie Könnten wir erfahren, welche Lösung für diese Frage gefunden wurde, sobald die heutige Wahl entschieden ist?
Steve Kerry Oct 26, 2012:
Perhaps the ball is part of the fitting? Many hydraulic fittings incorporate a ball valve. What they may actually be testing is the sealing surface of the ball which forms part of this valve.
e.g. http://www.krob.eu/products.aspx?p=1 In this case, the "ball measurement method" would still be ok, or "ball inspection/testing method" could be used. If in doubt, I'd go with literal every time, but hopefully more context will clarify matters.
Johannes Gleim Oct 25, 2012:
Bevor ich es wage sowas wie "ball method" vorzuschlagen, möchte ich gerne fragen, ob es nicht weitere Informationen zu der Meßmethode gibt. Vielleicht an anderer Stelle im Text. Gegebenenfalls auch unter Bewertung der Prüfergebnisse. Oder hat die Kugel etwas mit der Stutzen- oder Flanschform zu tun?

Good luck!

... if they are actually testing the O-rings or other rubber-type seals. IRHD = International Rubber Hardness Degrees

Peer comment(s):

neutral Steve Kerry : Certainly a possibility, but to me Dichtfläche implies a (usually metallic) surface, rather than a seal, which I would call a Dichtung.

I do also think of metal surfaces when I read Dichtfläche, but to be honest - a Stutzen usually doesn't have a Dichtfläche, it's the flange at the end of the Stutzen. Anyhow, you may very well be right about me being wrong ;-)

ball measurement method

I haven't been able to find this either, but I don't think it relates to hardness testing, which would probably be done at the material selection stage. They would be far more likely to insert a ball into a hydraulic connection stub to either a) check the seal around the circumference or b) (more likely) to determine the possible ovality of the sealing surface of a tubular fitting by measuring the depth to which a standard ball could be inserted. Difficult to say without more context.

The ball impact test is developed as a package-level measure of the board

I am pretty sure that this is just another expression for Kugelschlagprüfung oder Fallhärteprüfung
