gypsum board, except gypsum la&, providing a greater fire-resistance than regular gypsum board of the same thickness Type X (special fire-resistant) gypsum board, when tested in accordance with Test Methods E 119, shall provide the following minimum fire resistance ratings for the assemblies described: / I I ! i ~ 1o n e hour for a H-in [ l - m ] thickness applied to a partition in a single-layer application on each side of 3%-in [ - m ] deep non-loadbearing galvanized steel studs complying w i h Specificat~onC 645, spaced 24 in (610 m.ml on center The %in (15.9-mm] thick gypsum board 48 in [

oriented parallel to and located over studs and staggered on opposite sides of the assembly, and X1.1.2 TWOhours for a M-in [12.7-mm] thickness applied to a partition in a double-layer application on each side of [64-mm1 deep non-ioadbearhg galvanized steel studs complying with Specification C 645, spaced 24 in [610 mm] on center The 48-in [ 2 - m ] wide base layer shall be anached using 1-in ( -
