The
41、y arenot part of this specification.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 a testto define the glass mat gypsum panel as meeting the requirements of type X products. These tests do not indicate a preferredapplication
42、 nor do they limit the use of the product in other fire rated assemblies.All gypsum panel products for which type 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.
