Harmonised standards
Harmonised standards
(OP)
Are the EN standards the only harmonised standards, what about DIN standards, AD merkblatter, British standard,... My question is can we consider that all standards coming from an European country are harmonised standards or not?
Thanks in advance

AD-Merkblatt is a German vessel Code , not a standard.
RE: Harmonised standards
A harmonised standard is therefore a standard with an EN prefix that has been adopted in all the member states. This can be just EN or ISO EN or ISO BS EN or BS EN or DIN EN.
There is a time lag between a standard being published by CEN and all the member states ratifying the EN standard within their own structure.
What should happen when a harmonised standard is published is that each member state should withdraw their own similar standard before introducing the new harmonised standard. This is why BS5500 (Pressure Vessel Design Code) became PD5500 (Published Document) in the UK when EN 13445 was ratified in the UK.
Hope this helps.
