UNSPECIFIED Para:BS 5446-2:2003 Graphical symbols and signs - Safety signs, including fire safety signs. Signs with specific safety meanings (No longer current but cited in Building Regulations guidance)

Looks at safety signs that use geometric shapes and safety colours to provide information for actions to take to prevent, or reduce the risk of accidents, or for warning of hazards.

UNSPECIFIED Para:BS 5839-1:2002 Fire detection and fire alarm systems for buildings. Code of practice for system design, installation, commissioning and maintenance (AMD 15447) (+A2:2008) (No longer current but cited in Building Regulations guidance)

Makes recommendations for the provision of fire detection and fire alarm systems in a wide variety of premises. Covers a range of systems from simple manual (one or two call points) to complex automatic networked systems (comprising detectors, call points, sounders, control panels and indicating panels), pointing out the benefits of each rather than making recommendation of which to be used in specific premises types.

ADB2 2002 Para:12 Internal linings

To restrict the use of materials which ignite easily, which have a high rate of heat release and/ or which reduce the time to flash over, maximum acceptable 'fire propagation' indices are specified, where the national test methods are being followed.
These are determined by reference to the method specified in BS 476-6:1981 or 1989 Method of test for fire propagation of products. Index of performance (I) relates to the overall test performance, whereas sub-index (i1) is derived from the first 3 minutes of test.

ADB2 2002 Para:13 Internal linings

The highest national product performance classification for lining materials is Class 0. This is achieved if a material or the surface of a composite product is either:
a. composed throughout of materials of limited combustibility; or
b. a Class 1 material which has a fire propagation index (I) of not more than 12 and sub-index (i1) of not more than 6.
Note: Class O is not a classification identified in any British Standard test.

ADB2 2002 Para:13.7 External wall construction

The external envelope of a building should not provide a medium for fire spread if it is likely to be a risk to health or safety. The use of combustible materials for cladding framework, or of combustible thermal insulation as an overcladding or in ventilated cavities, may present such a risk in tall buildings, even though the provisions for external surfaces in Diagram 40 may have been satisfied.
In a building with a storey 18m or more above ground level, insulation material used in ventilated cavities in the external wall construction should be of limited combustibility (see Appendix A). This restriction does not apply to masonry cavity wall construction which complies with Diagram 32 in Section 10. Advice on the use of thermal insulation material is given in the BRE Report Fire performance of external thermal insulation for walls of multi-storey buildings (BR 135, 1988).

ADB2 2002 Para:8 Non-combustible materials

Non-combustible materials are defined
in Table A6 either as listed products, or in terms
of performance:

a. (National classes) when tested to BS 476:
Part 4:1970 Non-combustibility test for
materials or Part 11 :1982; or

b. (European classes) when classified as class
A 1 in accordance with BS EN 13501-1 :2002
Fire classification of construction products
and building elements. Classification using
data from reaction to fire tests when tested
to BS EN ISO 1182:2002 Reaction to fire tests
for building products - Non-combustibility
test and BS EN ISO 1716:2002 Reaction to
fire tests for building products. Determination
of the gross calorific value.

Table A6 identifies non-combustible products
and materials, and lists circumstances where
their use is necessary.

ADB2 2002 Para:9 Materials of limited combustibility

Materials of limited combustibility are defined in TableA7:
a. (National classes) by reference to the method specified in BS 476: Part 11 :1982; or
b. (European classes) in terms of performance when classified as class A2-s3, d2 in accordance with BS EN 13501-1 :2002, Fire classification of construction products and building elements, Part 1 Classification using data from reaction to fire tests when tested to BS EN ISO 1182:2002, Reaction to fire tests for building products -Non-combustibility test or BS EN ISO 1716:2002 Reaction to fire tests for building products -Determination of the gross calorific value and BS EN 13823:2002, Reaction to fire tests for building products - Building products excluding floorings exposed to the thermal attack by a single burning item.
Table A7 also includes composite products (such as plasterboard) which are considered acceptable, and where these are exposed as linings they should also meet any appropriate flame spread rating.
