At present the ENV specifies three test methods for assessing the performance of roofs under various conditions.  This amendment specifies a fourth test method under a new condition.

Prüfverfahren zur Beanspruchung von Bedachungen durch Feuer von außen

Méthodes d'essai pour l'exposition des toitures à un feu extérieur

¾ Modifier l�article afin de lire :
La présente Norme européenne spécifie quatre méthodes permettant de déterminer les performances des
toitures exposées à un feu extérieur. Les quatre méthodes d�essai évaluent les performances des toitures
dans les conditions suivantes :
Essai 1 : avec brandons enflammés ;
Essai 2 : avec brandons enflammés et vent ;
Essai 3 : avec brandons enflammés, vent et chaleur rayonnante supplémentaire ;
Essai 4 : méthode d�essai en deux étapes avec brandons enflammés, vent et chaleur rayonnante
supplémentaire.
Les essais évaluent la propagation du feu sur la surface extérieure de la toiture, la propagation du feu à
l'intérieur de la toiture (essais 1, 2 et 3), la pénétration du feu (essais 1, 3 et 4) et la production de flammèches
ou de débris enflammés tombant de la face inférieure de la toiture ou de la surface exposée de la toiture
(essais 1, 3 et 4).
Les essais 2 et 3 ne sont pas applicables aux toitures à géométrie irrégulière ou aux accessoires montés sur
la toiture (par exemple : ouvrants de ventilation et lanterneaux d�éclairage).
NOTE Les quatre essais énumérés ci-dessus n�impliquent aucun ordre de classement hiérarchique. Chaque essai
existe à part entière, sans aucune possibilité de remplacement ou d�échange réciproque.

Foreword
This document (ENV 1187:2002/A1:2005) has been prepared by Technical Committee CEN/TC 127
“Fire safety in buildings”, the secretariat of which is held by BSI.
This Amendment to the European Standard ENV 1187:2002 shall be given the status of a national
standard, either by publication of an identical text or by endorsement, at the latest by February 2006,
and conflicting national standards shall be withdrawn at the latest by February 2006.
ENV 1187:2002/A1 has been provided to comply with the EU Commission Decision to amend
Decision 2001/671/EC, establishing a classification system for the external fire performance of roofs
and roof coverings.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to announce this European Standard: Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,
Spain, Sweden, Switzerland and United Kingdom.
1 Scope
→ Amend clause to read:
This European Standard specifies four methods for determining the performance of roofs to external
fire exposure. The four methods assess the performance of roofs under the following conditions:
Test 1 – with burning brands,
Test 2 – with burning brands and wind,
Test 3 – with burning brands, wind and supplementary radiant heat,
Test 4 – two stage test method incorporating burning brands, wind and supplementary radiant
heat.
The tests assess the fire spread across the external surface of the roof, the fire spread within the roof
(Tests 1, 2 and 3), the fire penetration (Tests 1, 3 and 4) and the production of flaming droplets or
debris falling from the underside of the roof or from the exposed surface (Tests 1, 3 and 4).
Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances e.g.
ventilators and roof lights.
NOTE The four tests listed above do not imply any ranking order. Each test stands on its own without the
possibility to substitute or exchange one for another.
3 Terms and definitions
→ Insert the following new sub-clause
3.27
penetration by fire
the appearance on the underside of the specimen of any flaming or glowing other than that of the test
flame (Test 4 only), disregarding any test flame appearing through pre-existing openings in the test
specimen
→ Insert the following new clause:
7 Test 4 – Two stage test method incorporating burning brands, wind and
supplementary radiant heat
7.1 Test equipment
7.1.1 Brands
The free standing test brand shall comprise a simulated town gas flame (55,2 % Hydrogen, 27,4 %
Natural Gas, 17,4 % Nitrogen) (230 ± 10) mm long from a (9,5 ± 0,1) mm diameter orifice which shall
be set prior to application on the test specimen.
7.1.2 Wind
Provision is made in the test to simulate the effect of a wind of 6,7 m/s by applying suction to the
lower side of the roof specimen. Apparatus shall be provided, capable of reducing the pressure on the
underside of the specimen by (15 ± 1) Pa below that on the upper side, for the duration of the test.
The suction under the specimen shall be measured. An inclined tube manometer may be used for this
purpose.
7.1.3 Radiant panel
A (915 ± 5) mm square radiant panel shall be provided, capable of being supported either at an angle
of 45° or horizontal according to the test required, and shall comprise four (300 ± 5) mm square
surface combustion panels with their centres arranged at the corners of a square of (480 ± 5) mm side
(see Figure 14).
The radiation incident on the specimen is established with the radiant panel in the horizontal test
position and the calibration element set at a perpendicular distance of (585 ± 5) mm from the radiant
panels. The radiant panels shall be capable of providing an incident radiant heat flux distribution on
the surface of the calibration element such that the heat flux at the four major axes, as shown in
Figure 15, is (12 ± 1,5) kW/m .
A 25 mm diameter Schmidt Boelter heat flux meter with a range of (0 – 50) kW/m shall be used. The
centre of the heat flux meter receiving radiation from the radiant panels shall be flat, circular and
coated with a durable matt black finish. It shall be water cooled. Radiation shall not pass through any
window before reaching the target. The instrument shall be robust, simple to set up and use, and
stable in calibration.
The calibration of the he
