This European Specification 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 – with two stages 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.

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.


ENV 1187 Test 1

The Test 1 equipment consists of:

  • A basket – Made from 3mm diameter mild steel wire forming a mesh of approximately 50 × 50mm. This is an open basket at the top and bottom and has four projecting feet 10mm long, one at each corner. The outer dimensions of the basket is 300 × 300 × 200mm deep. The mass of the basket is 650 ±50 grams
  • Wood wool – Consists of fibres approximately 2mm wide × 0.2mm to 0.3mm thick and is manufactured from softwood
  • Balance – Used to weigh the wood wool and it has a nominal capacity of at least 2 kilos and an accuracy of ±1 gram
  • Timer – Minimum accuracy of ±5 seconds over 24 hours.

ENV 1187 Test 2

This Test 2 equipment consists of:

  • Air channels equipped with fans and a lid – This air channel is made of 1.0mm thick steel plates. The wall channel section placed between the lower and the upper air channels is made of steel plates and non-combustible fibre reinforced calcium silicate boards with a thickness of 11 ±2 mm and a density of 680 ±50 kg/m3
  • Crib ignition stand – The crib ignition stand is protected from air currents and consists of a support of the wood crib and a line burner with five vertically oriented burner tubes. The line burner is mounted centrally on the support with the axes of the burner tubes and the lowest edge of the crib in the same plane
  • Wood crib – 8 pieces (in which 6 pieces are nailed to the remaining 2 pieces at a distance of 8 mm between each of them) of 10 × 10 × 100mm pine wood containing no knots make the source of fire
  • Constant temperature drying oven of 105 ±5°C
  • Desiccator
  • Balance
  • Timer
  • Air velocity measuring devices
  • Flow meter
