Eurocodes are a set of harmonized European standards for the structural design of buildings and civil engineering structures. There are 10 of them made up of 58 parts.
(Referred from European Commission > Joint Research Centre > Eurocodes)
National Annexes (NAs) are documents produced by individual countries adopting Eurocodes that specifies parameters such as climate and legislation to account for local differences. They are used in conjunction with the Eurocodes. For example, the prefix for the NAs produced by the UK for the Eurocodes adopted is NA to BS EN.
There are two common misconceptions when it comes to using Eurocodes and National Annexes. See "Common Misconceptions on Eurocodes and National Annexes" below.
1. I need a Eurocode adopted by Singapore, e.g. SS EN 1991-2 (2010) but I could not find it. Can I use the soft copy of BS EN 1991-2:2003 from British Standards Online instead?
It depends on whether Singapore follows the December 2004 and April 2010 amendments that the British made. Do not let the date 2003 mislead you into thinking the standard was last updated in 2003. You are recommended to view the full standard document to confirm.
The Library is unable to advise if Singapore follows any of the corrigenda for any of the British standard.
In the British standard itself, the start and finish of text introduced or altered by amendment is indicated in the text by tags. E.g.
i. What is indicated within those tags might not apply to Singapore.
ii. The rest of the British standard is exactly the same as the Singapore standard and the original European standard.
2. I need the National Annex to SS EN 1991-2 (2010) but I could not find it. Can I use the National Annex to BS EN 1991-2:2003, since the soft copy is available in British Standards Online?
No, because national annexes differ from country to country.
Eurocodes came into effect on 1 April 2013. The table below lists the Eurocodes adopted by Singapore, either in full or in parts. To find Eurocodes, see Major Standards.
