ALTERNATE DEFINITION FOR TYPE XINTRODUCTIONThis Appendix gives general information and also suggestions for inclusions to be made elsewhereby the specifier. They are not part of this specification.The definition of type X as given in 4

25、.3 and the alternate definition given in this appendix, areintended only as a test to define the gypsum wallboard as meeting the requirements of type X. Thesetests do not indicate a preferred application nor do they limit the use of the product in other fire ratedassemblies.All gypsum panel products

26、, except lath, shaftliner, and coreboard, use the same test for type Xproducts, therefore the type X designation indicates a consistent level of fire resistance.X1.1 Gypsum wallboard, type X (special fire-resistant)designates gypsum wallboard providing a greater fire resis-tance than regular gypsum

27、wallboard of the same thickness.Type X (special fire-resistant) gypsum wallboard, when testedin accordance with Test Methods E 119, shall provide thefollowing minimum fire resistance for the assemblies de-scribed:X1.1.1 One hour for a 16.0 mm thickness applied to apartition in a single layer applica

28、tion on each side of 90 mmdeep non-loadbearing galvanized steel studs complying withSpecification C 645, spaced 600 mm on center. The 16.0 mmthick gypsum wallboard 1200 mm wide shall be attached using25 mm long drywall screws spaced 200 mm on center along theedges and ends, and 300 mm along intermed

29、iate studs. Alljoints shall be oriented parallel to and located over studs andstaggered on opposite sides of the assembly, andX1.1.2 Two hours for a 13.0 mm thickness applied to apartition in a double layer application on each side of 65 mmdeep non-loadbearing galvanized steel studs complying withSp

30、ecification C 645, spaced 600 mm on center. The 1200 mmwide base layer shall be attached using 25 mm long drywallscrews spaced 300 mm on center along board edges, ends, andalong intermediate studs. Joints shall be oriented parallel to andlocated over studs and staggered on opposite sides of theassem

31、bly. The 1200 mm wide face layer shall be attached using40 mm long drywall screws spaced 300 mm along board edges,ends, and along intermediate studs. Joints shall be orientedparallel to and located over studs, offset 600 mm from the baselayer joints, and staggered on opposite sides of the assembly.A
