B.S. 85192010
  • New Code of Practice for the selection of
    fire-resistant cables and systems for life safety
    and fire fighting applications
  • Provides guidance and recommendations and links
    to Approved Document B (Part B) of the building
    regulations, B.S. 9999, B.S. 7846 cable standard
    and tests defined in B.S. 8491 and BSEN
    502002006
  • Recommends cable survival times and installed
    cable system requirements
  • Does not take precedence over B.S. 5839 for alarm
    systems and B.S. 5266 for emergency lighting

3
Background to B.S.85192010
  • Modern building technology involves Fire Safety
    Engineering
  • Active Fire Safety systems such as sprinklers and
    smoke
  • evacuation systems are required to operate both
    in evacuation and fire fighting phases.
  • In this context it was considered that the Cable
    performance requirements contained in BS 7846
    were inadequate for certain applications.
  • Smoke ventilation systems
  • Electrically operated fire doors and curtains
  • Pressurization fans
  • Sprinklers and wet-riser pumps

4
B.S.85192010
  • Complex Buildings have a Fire Safety Engineering
    Infrastructure
  • Greater emphasis on Circuit Integrity
  • Cables must have a suitable performance level
  • New Tests have been introduced

5
B. S. 85192010
  • Defines new Fire Performance (Circuit Integrity)
    requirements for Power cables
  • Does not cover
  • Cables lt 20mm in Diameter
  • Wiring systems installed in Conduit
  • Wiring systems for Alarm and Sounder circuits (BS
    5839)
  • Also defined are requirements for cable fixings
    and joints, diverse cable routes, and cable
    support systems

6
Cable Classes -Ratings
  • B S 8519 defines two types of application
  • Life Safety systems Systems that must remain
    operational to alert, evacuate, and protect
    people
  • Category 1- 30 minutes
  • Category 2- 60 minutes
  • Fire Fighting systems - Active systems for
    protecting and assisting fire-fighters
  • Category 3- 120 minutes
  • 3 Categories of cable performance are defined

7
Fire survival times Category 1
  • For means of escape 30 minutes fire survival
    time, cables shall
  • For Power cables gt20mm meet B.S. 8491 for 30
    minutes
  • For Control cables meet BSEN 50200 test for 30
    minutes

8
Fire survival times Category 2
  • For means of escape 60 minutes fire survival time
    cables shall
  • For Power cables gt20mm meet B.S.8491 for 60
    minutes.
  • For Control cables meet BSEN 50200 test for 60
    minutes and for 120 minutes with water spray as
    per BS 8434-2

9
Fire survival times Category 3
  • For Fire Fighting 120 minutes fire survival time
    cables shall
  • For Power cables gt20mm meet B.S. 8491 for 120
    minutes
  • For Control cables meet BSEN 50200 test for 120
    minutes and the 120 min survival period when
    tested In accordance with Annexe B of BS 8519
    (115 minutes fire and impact at 930C followed by
    5 minutes of fire, water and impact)

10
B.S. 8519 cable classifications
11
The Fire Tests BSEN 50200
  • BSEN 50200 water Spray
  • Test is integrated But
  • Impact is indirect
  • Water is applied via a sprinkler head not a
    pressure hose

12
The Fire Tests- BS 8491
  • Based on the BS 7846 test but is Integrated.
  • Constant temperature attack at 842C
  • Direct mechanical impact 10 N
  • Pressure Water jet (6.3mm hose,12.5l/m) during
    final 5 minutes of test - to simulate fire hose

13
Drakas Offering
Firetufpowerplus utilises additional fire
barriers and new Halogen Free, Low Smoke material
technology, compared to B.S.7846 F2 cable FTP.
It has conventional wire armour design, and
complies with B.S.7846, and B.S.8491 to the 120
minute rating (category 3) FTP120 has been
independently tested by LPCB and has a full
approval from BASEC
14
Approved Document B Protected Power Circuits
  • Critical electrical Circuits must function
  • Cables must be sufficiently robust
  • Cable routes, physical protection and cable
    supports and joints, if used, shall not reduce
    functionality in the event of fire.

15
FTP 120 Applications
16
FTP120 now LU Approved
  • Draka is now the only manufacturer with LU
    approval for BS 8519 applications
  • LU are now promoting BS 8519 as the optimum level
    of safety, and this level of safety is being
    specified into ALL LU designs
