This Published Document has been prepared by Technical Committee ISE31.It supersedes PD 970:2001, which is withdrawn.Some errors in PD 970:2001 have been corrected and some steel grades that arein regular use in the UK have been introduced as they did not have equivalentsin the newly published European Standards and the withdrawal of BS 970 inwhich they were listed had resulted in them not being identified within anycurrent document.
