Principles of European StandardsHarmonisation of individual
countries specifications and test Harmonisation of individual
countries specifications and test methods to eliminate barriers to
trade!
27 (soon to be 28) countries currently represented and bound to
implement the ENs (12 in 1989!)
BS EN h t th it /l l BS ENs have greater authority/legal
