British Standard. However attention is drawn to the fact that during BSl as a member of CEN is obliged to publish EN 10027-1:2016 as athe development of this European Standard the UK mittee voted against its approval as a European Standard.
The UK mittee suggested that amendments be made to Tablephysical properties between hot-finished and cold-formed structural 1 of EN 10027-1:2016 to address the differences in mechanical andfor these products within Eurocode 3 - Design of Steel Structures hollow sections. Currently despite there being different design rulesand Eurocode 4 - Design of Composite and Steel Structures bothsame steel names. The UK proposal was for this to be changed hot-finished and cold-formed hollow sections have exactly theto enable a clear differentiation between the two products and hence eliminate any danger that an incorrect product might besupplied or used in a structure. However as the changes requestedusers of structural hollow sections to apply suitable checks to ensure by the UK mittee were not adopted the mittee advisesthat they have been supplied with the correct products which are properly CE marked and certified in accordance with the EuropeanCommission Construction Products Regulation.
The UK participation in its preparation was entrusted to TechnicalCommittee ISE/100 Steel General Issues.
A list of organizations represented on this mittee can beobtained on request to its secretary.
