The difference between BS and BS EN is that a “BS” (British Standard) document is generally confined to the UK and many British territories, whereas a “BS EN” (British Standard European Norm) document applies to many European countries and includes the UK. The British Standard Institution explains that standards aren’t the same as regulations and laws. By following a standard, it doesn’t necessarily mean you’re within the relevant law. Most standards don’t cite the law as the legislation could change within the lifetime of the standard. For a cylinder to achieve this rating it is tested in the manner equivalent to the BS 3621:2007 and the minimum requirements of BS EN 1303:2005. ** 2 Star rating TS007:2012 and TS007:2019 are Technical Specifications that have been produced in the form of a document by the Door & Hardware Federation (DHF) and the Glass and Glazing Federation (GGF). The DHF and GGF worked closely alongside Secured by Design (the Association of Chief Police Officer’s crime prevention initiative) to develop the TS007 Kitemark standard. If a product meets a certain EN number and conforms to the British standards it can then be classed as a BS EN product; BS indicating it meets all relevant British standards and the EN number displaying its rating within each category.

An EN number is the number given to a product to signify the standard to which that particular product has been manufactured. The EN number is an 8-digit code. Each digit represents the rating of a particular feature of the product.The BSI Kitemark can be used to indicate certification by the British Standard Institution, but only where a Kitemark scheme has been set up around a particular standard. It is mainly applicable to safety and quality management standards. There is a common misunderstanding that Kitemarks are necessary to prove compliance with any British standard, but in general, it is neither desirable nor possible that every standard be ‘policed’ in this way.
