German term or phrase: GF Methode
The abbreviation 'GF' occurs twice in a German patent about PU binders for casting moulds and cores.

First, in the coldbox process, quartz sand, resin solution and activator are mixed. "Mit diesen Mischungen wurden ... Prüfkörper (+GF +Riegel) geschossen."

Then, the flexural strengths (Biegefestigkeiten) of these specimens were determined by the "GF Methode".

Does anyone know what GF stands for?

gradient flux


Explanation:
In order to understand the processes that control sea-to-air fluxes, we have been devel-oping the Gradient Flux (GF) and Relaxed Eddy Accumulation (REA) techniques forfield measurements of trace gas exchange. However, REA and GF rely on empiricallyderived functions that have been validated over land only; the universality of thesefunctions and their applicability in the marine environment have not yet been fullyevaluated.

Techniques that can be used for the measurement of DMS fluxes and that do not rely upon fast response sensors for DMS are the relaxed eddy accumulation (REA) and gradient flux (GF) techniques. These techniques are relatively simple to apply and allow the measurement of a variety of gases. However, REA and GF require empirical relationships to estimate the flux.

Thank you for the reference you provided. This is obviously a possible definition of GF, but it doesn't seem to fit my context.

Glasfaser


Explanation:
It might fit in with the first example, but I'm not sure about the GF_Methode referred to in the second example.

Thank you for this suggestion. I have come across GF meaning Glasfaser and they are certainly used in polymers, but unfortunately there are none in the formulation in question.

Explanation:
Better ask the client. It seems to me that GF in the 2nd appearance is different from the 1st one. The first GF could for instance also stand for Grundfläche which then again wouldn't work for the 2nd one. The suggested gradient reflux might work for the second GF but I can't see it working for the first.

Erica suggested of course gradient flux, not reflux. I\'m afraid that techtranuks suggestion IMHO doesn\'t fit in at all.

Thank you - I'm not actually declining your answer, in that I agree that this is one that needs to be referred to the client now.

neutral  Erica Magielse: Could be. I searched for GF methode (in Dutch) and got some hits mentioning gradient reflux. I have no idea what it is, though ...

  -> Well, most of the time it has to do with what your links describe: measuring of gases. Thinking about it, I've never heard of it in a context with producing (plastic) samples.
