ALTERNATE DEFINITION FOR TYPE XX1.1 The definition of type X as given in 4.2 and 4.3 and the alternate definition given in this appendix, are intended only as atest to define the glass mat gypsum panel as meeting the requirements of type X products. These tests do not indicat
45、e a preferredapplication nor do they limit the use of the product in other fire rated assemblies.X1.2 This appendix gives general information and also suggestions for inclusions to be made elsewhere by the specifier. They arenot part of this specification.X1.3 All gypsum panel products for which typ
46、e X is defined, except shaftliner gypsum panel, use the same test for type Xproducts, therefore the type X definition indicates a consistent level of fire resistance.X1.4 Glass mat gypsum panel, type X (special fire-resistant) designates glass mat gypsum panel providing a greater fire-resistancethan
