BS - British Standard Fire resistance

BS 476-31 British Standard: smoke tightness of doors

Fire tests on building materials and structures. Methods for measuring smoke penetration through doorsets and shutter assemblies. Method of measurement under ambient temperature conditions

Tipo: Test standard

Standard: BS 476-31

Clienti:

With this English regulation, it is possible to carry out tests to evaluate the loss in cubic meters per hour per meter of joint length, with the exception of the lower one. It 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 in this standard the medium temperature loss, the equivalent of Sm-S200, is not evaluated.
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. In both, Appendix C refers to fire doors that can be classified according to EN13501 or BS 476-22. In the latter case, then they will be doors called FD (Fire door) and FD xx S, where xx is the duration in minutes, S is the smoke seal according to BS 476-31.
THE CHEMOLLI FIRE CONTRIBUTION
When it comes to testing, we provide our experience and our KNOW-HOW. Having always done this type of activity, as specialists, we offer you complete advice during all the laboratory experimentation phases, from design to documentation of results. THE METHOD Listening is the most important phase of our interaction: we want you to develop a product that is the sum of your identity and your needs. First of all, we'll try to understand your real needs, the channels and the markets you want to measure yourself on. Then we will show you how the testing and certification process takes place: we need to deal with you, to fully grasp your point of view. Then, we concert a proposal that respects - compatibly with the required performances - your product lines, your production lines and, as far as possible, the potential economies of scale by using products and methodologies already consolidated in your company. EMPATHY Beyond the opportunities, which we will show you, we will then advise you what we would do, in your shoes. We advise with our experience on what, how and where to test. In which laboratory should you test? In the one that best suits your needs! THE PROJECT Once the key is turned, we prepare a project that is exhaustive of all the details. Which materials and components to use, an important part of our dialogue on which we can best advise you. In addition to this, a cost sheet and a forecast of weights, to allow you to check if your goals will be achieved. Using the best practices in the sector, we are convinced of this. ATYPICAL CONSULTANTS: WE TAKE CARE OF THE TESTING ACTIVITY A consultant gives advice, then lets the client put it into practice. We are not like this: we take off tie and put on our work clothes when needed. Once the production of the samples has been launched, we are present during the gluing of the doors, we offer support during processing and hardware installation, we proceed with our technicians to install the samples in the laboratory and we are physically present at the test. We manage the post-test documentation review phase, we illustrate the documentation and remain available for all issues related to results management.
