It is very wide issue. What exactly do you want to know about this topic?
Thank you all for your answers... (the english ones... )
I'd need to:
clarify what is the 'B' mark (in polish znak boduwlany, isn't it?).
define the difference between safety mark (znak bezpieczeństwa) B and the construction B mark

which certificate does item on the ROZPORZĄDZENIE RADY MINISTRÓW z dnia 9 listopada 1999 r. list need(http://www.ciop.pl/5522.html)
if a construction production isn't in that list, do I need for it TECHNICAL APPROVAL (aprobatą techniczną)?
if so, is znak budowlany to certify compliance with this approval?
what happened before may 1st 2004, and in the meantime between may 2004 and the official approbation of the EN 14351 for windows and pedestrian door CE marking
