With this English standard, it is possible the testing for leakage in cubic metres per hour per metre of joint length, except for the lower one. This is an accessory requirement in many markets such as English, German and the United Arab Emirates.

THE TEST  

The main difference with the European standard is the fact that this standard does not assess medium temperature leakage, the equivalent of Sm-S200.

REQUIREMENTS

Typically, the requirements for fire resistant doors for fire prevention are contained in the documents:

  • “Her Majesty’s Government, The building Regulations 2010, Fire safety, Approved document B – Volume 1: Dwellings”;
  • “Her Majesty’s Government, The building Regulations 2010, Fire safety, Approved document B – Volume 2: Building other than dwellings”.

At the bottom of the page you will find the 2019 versions for use in England. Both Appendix C talks about fire doors which can be classified according to EN13501 or BS 476-22. In the latter case they will then be referred to as FD (Fire doors) and FD xx S, where xx is the duration in minutes, S is the smoke seal according to BS 476-31.
