Flammability testing device RTA-1187-4

for roofing materials

Compliance ENV 1187 Test 4, BS 476 Part 3, EN 13501-5 The ENV 1187 Roofing Test 4 Device is designed to determine the performance of roofing materials with two stages incorporating burning brands, wind and supplementary radiant heat. ENV 1187 describes four test methods: • ENV 1187 Test 1 - With burning brands. • ENV 1187 Test 2 - With burning brands and wind. • ENV 1187 Test 3 - with burning brands, wind and supplementary radiant heat. • ENV 1187 Test 4 - With two stages incorporating burning brands, wind and supplementary radiant heat. And, the tests listed above are independent and not substitutable with each other. • Test 1, 2, 3 assess the flame spread across the external surface of the roof. • Test 1, 3, 4 assess the penetration of the flame and the generation of burning molten droplets. • Test 2, 3 are not applicable to geometrically irregular roofing materials or roof-mounted equipment such as ventilation units and roof lights. ENV 1187 Roofing Test 4 Includes 2 stage tests: Stage 1 – Preliminary ignition test with burning brands. The burning brand is applied for 1min starting at the center of the upper surface of the specimen, without exposure to radiant heat. Stage 2 - Penetration test with burning brands, wind and supplementary radiant heat. The upper surface of the specimen is exposed to the 12.5kw/m2 radiant heat, and after 5 mins from the start of the test, the burning brand is applied to the surface of the specimen by moving once up and once down the center of the specimen at a rate of 0.29m/10s. The specimen remains exposed to the radiant panels for 1 hour in total.
