New and amended reference documents

All the information we provide in NBS is supported by a wide range of reference documents. These can be amended, withdrawn or superseded between NBS Updates. To help you keep up to date, we provide a list of all changes made to reference documents since the last update.

British Standards are referred to throughout NBS. The British Standards Institution (BSI) amend and withdraw Standards and add new ones, which can have a significant impact on specifications or other documents that refer to them. Because of this, we keep a very close watch on which Standards are new or amended to make sure that NBS is always up to date. We compile lists of all Standards affecting NBS that have changed, and you can find an archive of them here.
