German term or phrase: Bestimmungsgrenze
I know this term and the other two I posted have been posted in Proz before, but I am having trouble separating the three, because the translations I find tend to overlap! I am proofreading another translator's work and in researching the terms, I initially thought:

"Bestimmungsgrenze" - decision threshold (translator: determination limit)

I find the name of a standard [DIN 32645 „Nachweis-, Erfassungs- und Bestimmungsgrenze unter Wiederholbedingungen"] translated everywhere on the internet as "Chemical analysis - Decision limit, detection limit and determination limit under repeatability conditions - Terms, methods, evaluation."

I also find "limit of quantification" for "Bestimmungsgrenze".

I can see that the translator went and changed the terms earlier in the text after finding the translation of the DIN document. But I am not at all sure which term I can use consistently throughout the document, especially given that the translation of the DIN document is used like this everywhere - where do I go with consistency, except if I add a note explaining that the DIN document appears like that on the internet? I cannot change the title of this standard, because people must be able to search for it on the internet, but I am not sure that the translation of the standard is the best choice of terminology...

determination limit
Explanation:
determination limit / limit of quantification

Determination limit
After the question of the capability of detection of an assay with respect to qualitative analysis has been clarified, the next question immediately arises: “How far can the existing calibration be utilised for quantitative analysis?” ISO 8466-1:1990 (“Calibration and evaluation of analytical methods and estimation of performance characteristics - Part 1: Statistical evaluation of the linear calibration function”) describes how the standard deviation of a method can be calculated from the residual standard error of the regression. This ISO was derived from DIN 38402-51:1986. The capability of quantifying a certain analyte can be characterised further by its minimum quantifiable concentration, called Determination Limit or Limit of Quantification (LOQ).

Reference: What Römpp says:

Reference information:
Bestimmungsgrenze
(Abkürzung BG; gelegentlich auch als Quantifizierungsgrenze bezeichnet). In der quantitativen chemischen Analytik versteht man unter der Bestimmungsgrenze diejenige Konzentration eines Analyten in einem Untersuchungsobjekt, die mit einer vorgegebenen tolerierbaren, relativen Ergebnisunsicherheit bestimmt werden kann. Liefert ein Untersuchungsobjekt ein Messsignal, dem bei der Auswertung eine Konzentration unterhalb der Bestimmungsgrenze zugeordnet werden müsste, dann wird das Ergebnis mit „nicht bestimmbar“ (Abkürzung: n. b.) angegeben. Erst oberhalb der Bestimmungsgrenze ist die Signalstreuung akzeptabel gering, sodass man eine Konzentration als Ergebnis mitteilen darf.
