1.1 This test method covers procedures for determining the resistance to deflection and damage of floor and roof sheathing used in site-built construction subjected to concentrated static loads as well as impact loads from nonrigid blunt objects. It is applicable to wood and wood-based panels and boards, but is not intended to cover profiled metal decks, nor precast or cast-in-place slabs. Surface indentation is not evaluated separately from deflection. 1.2 Three applications are covered: roof sheathing, subfloors, and single floors. Roof sheathing is tested in both a dry and a wet condition, while subfloors and single floors are both tested in a dry condition, as well as a condition of having dried out after being wet. These moisture conditions are those commonly experienced with site-built construction. Note 1-Where it is anticipated that sheathing will be subjected only to dry conditions during construction and use, or else to greater moisture exposure than is indicated in 6.3.2, the corresponding exposure conditions may be modified by agreement between the interested parties. For example, shop-built construction may be tested dry only, although the possibility of exposure to high humidity or leaks and flooding during use should be considered.1.3 The values stated in metric (SI) units are to be regarded as the standard. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
