23 (1) In this section, class A-0 division means a division formed by a bulkhead or deck that is constructed (a) of steel or an equivalent material and suitably stiffened, and (b) to prevent the passage of smoke and flame after 60 minutes of exposure to a standard fire test; ( cloisonnement de classe A-0 ) class A-60 division means a division formed by a bulkhead or deck that is (a) constructed of steel or an equivalent material and suitably stiffened, (b) constructed to prevent the passage of smoke and flame after 60 minutes of exposure to a standard fire test, and (c) insulated with non-combustible materials so that, if either side is exposed to a standard fire test, after 60 minutes the average temperature on the unexposed face will not increase by more than 139°C above the initial temperature and the temperature at any point on the unexposed face, including any joint, will not increase by more than 180°C above the initial temperature; ( cloisonnement de classe A-60 ) class B-15 division means a division formed by a bulkhead, ceiling or lining that is (a) constructed and erected entirely from non-combustible materials, (b) constructed to prevent the passage of flame after exposure to a standard fire test for 30 minutes, and (c) insulated so that if either face is exposed to the first 30 minute period of a standard fire test, the average temperature on the unexposed face will not increase at any time during the first 15 minutes of the test by more than 139°C above that initial temperature, and the temperature at any point on the unexposed face, including any joint, will not increase by more than 225°C above the initial temperature after exposure for 15 minutes; ( cloisonnement de classe B-15 ) class H-120 division means a division formed by a bulkhead or deck that is (a) constructed of steel or an equivalent material and suitably stiffened, (b) constructed to prevent the passage of smoke and flame after exposure to a hydrocarbon fire test for 120 minutes, and (c) insulated with non-combustible material so that, if either face is exposed to a hydrocarbon fire test, after 120 minutes the average temperature on the unexposed face will not increase by more than 139°C above the initial temperature, and the temperature at any point on the unexposed face, including any joint, will not increase by more than 180°C above the initial temperature; ( cloisonnement de classe H-120 ) hydrocarbon fire test means a test in which a specimen division, which division resembles as closely as possible the intended construction of the division, includes, where appropriate, at least one joint and has an exposed surface of not less than 4.65 m 2 and a height or a length of not less than 2.44 m, is exposed in a test furnace to temperatures corresponding approximately to a time-temperature relationship defined by a smooth curve drawn through the following temperature points measured above the initial furnace temperature, namely, (a) at the end of the first 3 minutes, 880°C, (b) at the end of the first 5 minutes, 945°C, (c) at the end of the first 10 minutes, 1032°C, (d) at the end of the first 15 minutes, 1071°C, (e) at the end of the first 30 minutes, 1098°C, (f) at the end of the first 60 minutes, 1100°C, and (g) at the end of the first 120 minutes, 1100°C; ( essai de résistance au feu d’hydrocarbures ) low flame spread in respect of a surface, means that the surface restricts the spread of flame; ( à faible indice de propagation des flammes ) standard fire test means a test conducted in accordance with Regulation 3.2 of Chapter II-2 of International Maritime Organization International Conference on Safety of Life at Sea . ( essai standard de résistance au feu ) (2) Subject to subsection (3), on an offshore installation, (a) the wellhead and process areas on a production installation shall be separated from other areas by class H-120 divisions; (b) all control stations shall be separated from other areas by class A-60 divisions; (c) the accommodatio
