BS EN 3
Contents |
[edit] Introduction
The British Standards Institution (BSI) is the UK National Standards Body (NSB). It publishes standards and provides a range of books, self-assessment tools, conferences and training services. It also represents UK economic and social interests in European and international standards organisations.
[edit] History
BS EN 3 is a standard for portable fire extinguishers. All fire extinguishers manufactured in the UK (and Europe) must comply with this standard, which was originally published in 1996. When it was released, it replaced BS 5423:1987, which was withdrawn in 1997.
This standard was released in several parts. Some of the earlier parts have been withdrawn and replaced by updates.

[edit] Scope of BS EN 3
BS EN 3 sets the minimum uniform production - including quality levels - of portable fire extinguishers based on BS EN 3-7. It sets out the documentation requirements for details, including identification of key producers/manufacturers, identification of the extinguisher and related documents, CE markings, toxicology information and so on. It also provides details on testing, assessments and controls put in place during production.
Each part of the standard is available to download from the BSI website.
