Thank you XL83NL for your quick response. You think the actual static test coefficient is not mentioned formally, but already calculated into the proof load.
This could very well be the case in several manuals. But still then there are quit a lot where no static test coefficient is stated and...
The MD says in section 4.4.1 d. that the static test coefficient what is used must be mentioned in the manual. In existing manuals it hardly seems to be mentioned anywhere. I think it is mandatory for CE certification. Or am I missing something? Who knows more about this?
