Gasblandingens temperatur umiddelbart før PDP må ikke afvige mere end ±6 K fra den gennemsnitlige driftstemperatur, der måles under prøvningen uden brug af strømningskompensation (EFC).
The gas mixture temperature immediately ahead of the PDP shall be within ±6 K of the average operating temperature observed during the test, when no flow compensation (EFC) is used.
