BS 8519:2020 pdf free.Selection and installation of fire-resistant power and control cable systems for life safety, fire-fighting and other critical applications一Code of practice.
BS 8519 This British Standard gives recommendations and guidance on the selection and installation of fire-resistant power and control cable systems which need to maintain their circuit integrity for life safety and fire-fighting. It also gives specific  ecommendations for electrical system design for such applications, and for fire survival times. This British Standard is primarily intended for use in buildings which, due to their size, height, form or use, require the installation of life safety and fire-fighting systems, e.g. sprinkler pumps, wet riser pumps, smoke control systems, fire-fighting and evacuation lifts or other systems as required by the fire engineered strategy.It covers: the source of supply;the distribution voltage [high voltage (HV) or low voltage (LV)]; and
the appropriate location of the main intake rooms, HV switchrooms, LV switchrooms,transformer rooms, generator rooms, risers, fire life safety equipment plant rooms and fire-fighting/evacuation lift motor rooms/shafts.The British Standard can also be used for systems which need to maintain their circuit integrity during a fire because the function they support is critical for business continuity, property protection or environmental protection reasons.This British Standard does not give recommendations for those installations covered in BS 5839-1,BS 5839-8, BS 5839-9 and BS 5266-1, but makes reference to these standards.General The electrical system should be designed, installed and verified by a skilled person suitably competent to comply with BS 7671 and to install switchgear and controlgear conforming to BS EN 60947.The type of electrical distribution system selected during the design phase should be derived from a detailed process of consultation with the relevant authorities having jurisdiction over the project in question, taking account of the overall fire strategy. The design should be agreed at the earliest stage.NOTE Specifially with reference to other critical systems, the appropriate levels offire survival time are agreed in consultation between all interested parties.BS 8519 pdf download.
