1.1本试验方法涵盖了确定混凝土和粘土屋顶砖的机械抗拔力的程序，该程序与应用于屋顶的透气屋顶砖系统的抗风性有关。 1.2本程序涵盖用于将瓷砖应用于屋顶的机械固定连接系统、粘合剂固定连接系统和砂浆固定连接系统或连接系统的组合。 1.3以英寸-磅为单位的数值应视为标准值。括号中的值仅供参考。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 屋顶瓦与屋顶板或支撑结构的连接方法是混凝土和粘土屋顶瓦抵抗风作用的一个因素。在屋顶瓷砖的应用中，使用了几种连接系统，甚至是系统的组合。 当通过制造商批准并符合制造商说明的任何连接系统应用于屋顶时，瓷砖的机械抗拔力是瓷砖抗风作用的主要因素。本试验方法确定了与风引起的上拔力阻力相关的机械上拔阻力。自然风条件在强度、持续时间和湍流方面有所不同；这些条件超出了本试验方法模拟的范围。

1.1 This test method covers a procedure to determine the mechanical uplift resistance of concrete and clay roof tiles, which relates to the wind resistance of an air-permeable roof tile system as applied to a roof. 1.2 The procedure covers mechanically-fastened attachment systems, adhesive-set attachment systems, and mortar-set attachment systems, or combinations of attachment systems, that are used to apply tile to a roof. 1.3 The values stated in inch pound units are to be regarded as the standard. The values in parentheses are given for reference only. This standard does not purport to address all of the safety concerns, if any, 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. ====== Significance And Use ====== The method of attachment of roof tiles to the roof deck, or support structure, is one factor in the resistance of concrete and clay roof tiles to the action of wind. Several systems of attachment, and even combinations of systems, are used in the application of tile to a roof. The mechanical uplift resistance of the tile, when applied to the roof by any attachment system approved by, and in accordance with, the manufacturer’instructions, is a primary factor in the tile’resistance to the action of wind. This test method determines the mechanical uplift resistance that is related to resistance to the uplift forces acting as a result of wind. Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions are beyond the means of this test method to simulate.
