SS EN 206-1 : 2009
National Foreword This Singapore Standard was prepared by the Technical Committee on Building Structure and Substructure under the purview of the Building and Construction Standards Committee. This standard is the result of the review of SS 289 : Parts 1 to 4 : 2000 – ‘Specification for concrete’. SS EN 206-1 together with SS 544 – ‘Concrete – Complementary Singapore Standard to SS EN 206-1 – Part 1 : Method of specifying and guidance for the specifier and Part 2 : Specification for constituent materials and concrete’ replaces the SS 289 series of standards. This Singapore Standard is identical to EN 206-1 ‘Concrete – Part 1 : Specification, performance, production and conformity’ and is adopted with permission of CEN, rue de Stassart 36, B-1050 Brussels. This SS EN incorporates the CEN Amendments 1 (July 2004) and 2 (June 2005). The start and finish of text introduced or altered by CEN amendment is indicated in the text by tags, eg, text altered by CEN amendment A1 is indicated by A1>
