It does not have the same authority as an EN. It is used when there is insufficient agreement for an EN. Time Gives zoning, mass and volume flow rates, aerodynamic area of exhaust and inlet and minimum number of exhausts. Not very user friendly layout. Best spill plume calculation is difficult to use.

Product Details This European Standard, a part of the BS EN series, specifies pressure differential systems designed to hold back smoke at a leaky physical barrier in a building, such as a door either open or closed or other similarly restricted openings.
It covers methods for calculating the parameters of pressure differential smoke control systems as part of the design procedure. BS EN gives test procedures for the systems used, as well as describing relevant, and critical, features of the installation and commissioning procedures needed to implement the calculated design in a building.
It covers systems intended to protect means of escape such as stairwells, corridors and lobbies, as well as systems intended to provide a protected firefighting bridgehead for the Fire Services. The systems incorporate smoke control components and kits comprising these and possibly other components.
This standard gives requirements and methods for the evaluation of conformity for such kits. Replaces BS and specifies pressure differential systems designed to hold back smoke at a leaky physical barrier in a building, such as a door either open or closed , or other similar openings. It describes relevant and critical features of installation and commissioning procedures needed to implement the calculated design in a building.
It also covers systems intended to protect means of escape, such as stairwells, corridors and lobbies and systems intended to provide a fire fighting bridgehead for the Fire Services.
BS EN 12101-6:2005
It is intended for a variety of building types and applications, including single-storey buildings, mezzanine floors, warehouses with palletized or racked storage, shopping malls, atria and complex buildings, car parks, places of entertainment and public assembly and un-compartmented space within multi-storey buildings. This Technical Report does not include any functional recommendations for design parameters where the primary purpose of the SHEVS is to assist fire-fighting. NOTE Such functional recommendations need to be agreed with the fire service responsible for the building in question. The calculation procedures set out in the annexes of this Technical Report can be used to design the SHEVS to meet whatever recommendations have been agreed. This Technical Report does not cover the following: - smoke clearance, where smoke is exhausted from a building after the fire has been suppressed; - cross-ventilation, where wind-induced or fan-induced air currents sweep smoke through and out of the building, usually as part of fire-fighting operational procedures; - ventilation of stairwells, which usually represents a special application of smoke clearance and which does not necessarily protect the continued use of the stairwell; - fully-involved fires.
What is BS EN 12101?
Firstly, a tiny bit of back-story to fill in any gaps: What are smoke control systems? Fire is hot, dangerous to people and damaging to buildings and assets. That role falls to smoke, which is also hot but is full of toxic chemicals, travels extremely quickly and can completely obscure escape routes or fire fighter access in minutes. A smoke control system will guide, block and channel smoke away from said escape routes and allow for simpler and quicker fire fighter access by venting the smoke in accordance with the designed ventilation strategy.
