1.1 这些试验方法为评估安装在木材和木质材料中的紧固件的拔出和横向阻力提供了基本程序。钉子包括在本标准中作为钉子。 1.2 试验还为确定安装在木材和木质材料中的不同类型和尺寸的紧固件的可比性能提供了依据。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 一种木材或木基产品的抗拔钉子、订书钉或螺钉的能力是衡量其通过此类紧固件固定或被固定到相邻物体的能力的一种指标。影响这种抗拔力的因素包括木材的物理和机械性能；紧固件的尺寸、形状和表面状况；退出速度；在驾驶时间和退出时间之间，木材或紧固件发生物理变化； 紧固件相对于纤维轴的方向；以及预钻孔铅孔的发生和性质。 5.2 通过使用尺寸和类型一致的钉子、订书钉和螺钉，可以确定一种木材或木制品的抗拔力，并且可以比较两种或两种以上木材或木制品的此类值。类似地，不同尺寸或类型的钉子、订书钉或螺钉的比较性能可以通过使用特定木材的标准程序来确定- 基于产品，消除了木材或木质产品作为变量。由于试验方法的差异可能会对结果产生相当大的影响，因此，如果试验值与其他试验结果相关，则必须指定并遵守标准程序。

1.1 These test methods provide a basic procedure for evaluating the withdrawal and lateral resistance of fasteners installed in wood and wood-based materials. Spikes are included as nails in this standard. 1.2 The tests also provide a basis for determining comparable performance of different types and sizes of fasteners installed in wood and wood-based materials. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The resistance of a species of wood or a wood-based product to withdrawal of nails, staples, or screws is a measure of its ability to hold or be held to an adjoining object by means of such fasteners. Factors that affect this withdrawal resistance include the physical and mechanical properties of the wood; the size, shape, and surface condition of the fasteners; the speed of withdrawal; physical changes to wood or fasteners between time of driving and time of withdrawal; orientation of the fastener relative to the fiber axis; and the occurrence and nature of pre-bored lead holes. 5.2 By using consistent sizes and types of nails, staples, and screws, withdrawal resistance of a wood species or wood product can be determined, and such values for two or more wood species or wood products can be compared. Similarly, comparative performances of different sizes or types of nails, staples, or screws can be determined by using a standard procedure with a particular wood or wood-based product, which eliminates the wood or the wood-based product as a variable. Since differences in test methods can have considerable influence on results, it is important that a standard procedure be specified and adhered to if test values are to be related to other test results.
