Pete,
Without the fields, its guesswork! Immediately following the runway designator (field C) should be available runway length (D) and width (E) - but both are optional.
I *guess* that the interesting bits for testing purposes are deposits (F) and braking action (H) - depth (G) doesn't seem to fit the data.
So:
05 runway designator
620 slush/wet/clear
525 good/medium-poor/good
is my stab at it, but the first third of the runway looks odd! Basically, more info on fields required...
Tocsin.
