Dear friends,
Allow me to join in the discussion, please.
I think the topic of standards should not be seen limited.The European standards are not only Eurocodes, contrary Eurocodes are very little part of the huge quantity of the European standards.
While reading the posts I noticed that the topic is new for most members of the forum, so I'll give you a few simple explanations.
The European standards are two major groups - unharmonized and harmonized. The difference between these two types is essential, the harmonized standards are related to products that can be exported - chemical admixtures, precast concrete products, steel and others.
You should know one imortant fact about the harmonized standards - they are binding on all member countries of EUROPEAN UNION, There has to be the same requirements for products, no matter in what country of the Union you are located.
Other standards - such as EN 206-1 are not harmonized, as requirements to the concrete cannot be the same within the European Union, mainly due to differences in climatic conditions and peculiarities in the national construction practice. For example, Greece, Spain on one side and Norway on the other.
Much of the standards have national annexes, but it must be clear one thing about them - the annexes are valid only for the teritory of the given country and it can not contradict the basic standard.
I hope with the above I was useful to participants.
Regards.
