question about din en 12530
someone that has this standard,
please, does this describe the threshold approach angle as degree or as measurement from center (or bottom) of wheel? (not to tell me what value(s) specifed, just does this exist in this standard?)
i wish to avoid spending $71usd if this standard is the wrong one...maybe its 22884?
thanks,
alex |
