BS970, PD970, BS EN10027?

Hopefully one of our UK contributors can provide the best information but from the US side of the Atlantic I believe the position to be as follows:
The En series 36C etc were originally developed during WW 2 and were "officially" superceded by the BS 970 designations (832M13 etc) in 1970.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.

Carburize/rmetzger,

BS 970 has been generally replaced with BS EN standards. Most parts of BS 970 have been withdrawn/superceded with the exception of BS 970-1 which has been partially replaced. The following may help:-

BS 970-1 Replaced by BS EN 10084, BS EN 10085, BS EN 10087, BS EN 10095, BS EN 10250 & PD 970:2001.

BS 970-1 Replaced by BS EN 10089

BS 970-3 Replaced by BS eN 10277-1, BS EN 10277-2, BS EN 10277-3, BS EN 10277-4, BS EN 10277-5 and BS EN 10278.

BS 970-4 Replaced by BS EN 10090.

Did the PD970 standard come in between the BS970 and the new BS En standards (I'm finding references of if superseding the BS970) or is it a separate entity of some kind? Also, what is the current material designation standard to use for European steel? Do the designations of the BS 970 still hold (832M13) under the BS EN designation(if that's what is to be used) or has a new system been adopted (if so - any links to where a cross reference may lie?). Thanks for all the info
