DIN 4108 external render classifications

[james bertram]

Good morning - I am trying to determine the rainfall (or wdr) classifications used to determine DIN 4108 Group 1-3 external render classifications.

Unfortunately the DIN standard does not seem to be available in an English translation.

Are you able to provide or refer me to where I can find these classifications. The intent being to compare them to Australian rainfall (or wdr) to develop an equivalent exposure reference.

Thank you, James

Dear Mr. Bertram,

As far as i know the classification of different driving rain regions is based on the yearly amount of precipitation and the surrounding area. Maybe you can check it with the englisch version of the DWD climate atlas.

Furthermore the classification is, in accordance to the german standard 4108-3 :2012:

1) yearly sum of precipitation < 600mm/a and a sheltered location
2) 600 mm/a < yearly sum of precipitation < 800mm/a and an exposed location
3) yearly sum of precipitation > 800mm/a and an exposed location (e.g. coast line or the alps)

Hope this helps,

Kind regards,
Tobias Schöner
