BS970, PD970, BS EN10027?
BS970, PD970, BS EN10027?
(OP)
Can someone please provide some information regarding the current European and British steel standards and what designations are to be used for materials.
I am working with sources in Europe that use both the EN prefix for steels and also seem to be using the BS970 standards for designating chemical makeup (EN36C and 832M13). What is the most current accepted standard and can someone provide a run down of what designations are superseding older ones?
thanks

The En series 36C etc were originally developed during WW 2 and were "officially" superceded by the BS 970 designations (832M13 etc) in 1970.
I believe BS 970 is still current and still used.
On joining the European Community some harmonisation efforts included the production of BS EN 10027 which started life in the early 1990s.
I think - but UK contributors please correct me - that both BS 970 and BS EN 10027 are both valid.
