1.1 本试验方法应用于测量木材基板或复合材料在粗糙处理过程中可能发生的相对角部抗冲击性和其他损伤。该测试方法适用于所有木材基板，如胶合板、定向刨花板、硬质纤维板、刨花板和中密度纤维板以及其他复合板产品。 1.2 该试验方法包括确定和评估面板在预定恒载和冲击角的情况下从不同高度跌落的影响，以模拟等效的现场应用。 1.3 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 该测试方法确定了可用于测量相对拐角冲击阻力的拐角冲击损伤。

1.1 This test method shall be used to measure the relative corner impact resistance and other damage that may occur during the rough handling of wood-base panels or composite materials. This test method is suitable for all wood-base panels such as plywood, oriented strand board, hardboard, particleboard and medium density fiberboard as well as other composite panel products. 1.2 This test method covers determination and evaluation of the effects of panels being dropped from various heights with a predetermined amount of dead load and angle of impact to simulate an equivalent field application. 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 This test method determines the corner impact damage that could be used to measure the relative corner impact resistance.
