The UK voted against this standard at the CEN Formal Vote stage becauseUK industry considered the standard to be insufficient in providing suitablespecification requirements for grouting materials and procedures, particularly for highway bridges.The UK conducted significant development work and subsequently published ConcreteSociety Technical Report No. 47  Durable Bonded Post Tensioned Concrete Bridges , prepared by a Concrete Society Working Party in collaboration with the ConcreteBridge Development Group (September 1996), to which reference may be made. At the CEN Formal Vote stage, however, the analysis of voting resulted in a positive vote and in accordance with CEN/CENELEC Internal Regulations Part 2 :  Common rules for standards work  EN 445 was accepted as a European Standard.
