EN ISO 11612 Heat & Flame
Letter A (EN 15025) This test consists of applying a flame to a fabric sample for 10 seconds. To pass the test, the after flame & smoulder times and formation of holes must be within the tolerances within the standard. The application of a flame can take place in two ways: Code Letter A1 Surface Ignition, ISO15025 A Procedure A (leads to Class A1), the flame is applied horizontally to the face of the fabric No specimen shall permit any part of the lowest boundary of any flame to reach the upper or either vertical edges No specimen shall give hole formation of 5mm or greater in any direction, except for an inter-lining that is used for specific protection other than heat and flame protection. No specimen shall give flaming or molten debris The mean value of after flame time shall be ≤ 2s The mean value of afterglow time shall be ≤ 2s Code Letter A1 Edge Ignition, ISO15025 B Procedure B (leads to Class A2), the flame is applied to the bottom edge of the fabric sample. No specimen shall permit any part of the lowest boundary of any flame to reach the upper or either vertical edges No specimen shall give flaming or molten debris The mean value of after flame time shall be ≤ 2s The mean value of afterglow time shall be ≤ 2s Letter B (ISO 9151) Convective Heat: determination of the heat transmission when exposed to flames. The sample is held above the flame and the rise in temperature on the topside of the sample is measured with a calorimeter. The length of time the sample can remain exposed before its temperature rises by 24 °C is determined. B1: 4 < 10 seconds, B2: 10 < 20 seconds, B3: 21 seconds and longer Letter C (ISO 6942) Exposure to Radiant Heat. In this test, a fabric sample is exposed to radiant heat (infrared rays). The temperature on the reverse (unexposed) side of the sample is registered using a calorimeter. Subsequently, the length of time the sample the sample can remain exposed before its temperature rises by 24°C is measured. The test procedure is the same as ISO 11611, but the classification is different: C1: 7 < 20 seconds, C2: 20 < 50 seconds, C3: 50 < 95 seconds, C4: 95 seconds and longer Letter D and E (ISO 9185) D = Aluminium E = Molten Iron Determining the level of protection against spatters of molten metal. A membrane (with similar properties to human skin) is attached to the reverse of the fabric sample sequentially rising quantities of molten metal (Aluminium or Iron as applicable) are splashed on the sample. The quantity of molten metal which deforms the membrane is determined. The classification for molten aluminium is: D1: 100 < 200 grams, D2: 200 <350 grams, D3: 350 grams and more The classification for molten iron is: E1: 60 < 120 grams, E2: 120 < 200 grams, E3: 200 grams and more Letter F (ISO 12127) This is a new test to establish a value for contact heat. The classification in this respect: F1: 5 < 10 seconds, F2: 10 < 15 seconds, F3: 15 seconds and longerDetails
