1.1 本试验方法测定了蜂窝夹芯材料的静态能量吸收特性（压溃应力和压溃行程）。由于蜂窝芯材料将放置在结构夹层结构中，因此通常在垂直于面板平面（也称为面对面）的方向上确定这些特性，以用于设计目的。 1.2 允许的芯材仅限于蜂窝形式的芯材。 1.3 本试验方法不适用于稳定蜂窝芯材料（蜂窝芯材料的面对面浸在树脂中以抵抗局部压碎）或夹层试样（面对面粘接到蜂窝芯材料）的压碎试验。 1.4 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.4.1 在文本中，英寸-磅单位显示在括号中。 1.5 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。 1.6 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 由于夹层蜂窝芯材料在被压碎时能够承受压缩载荷，因此在能量吸收应用中被广泛使用。正确设计利用夹层蜂窝芯材料的能量吸收装置需要了解蜂窝芯材料的压溃应力和压溃行程特性。 5.2 本试验方法中包含的程序旨在评估静态压缩载荷下夹层蜂窝芯材料的压碎应力和压碎行程特性。根据蜂窝芯材料厚度、芯材料密度、冲击速度等因素，蜂窝芯材料的动态压碎应力可能与静态载荷下测得的不同。 5.3 本试验方法提供了获得夹层蜂窝芯材料结构设计特性、材料规范、研发应用和质量保证的压缩压碎应力和压碎行程的标准方法。 5.4 本试验方法不适用于稳定蜂窝芯材料（蜂窝芯材料的面对面浸在树脂中以抵抗局部压碎）或夹层试样（面板粘合到蜂窝芯材料）的压碎试验。 5.5 因此，应报告影响压缩压碎应力和压碎行程的因素包括:蜂窝芯材料、材料制造方法、芯材料几何形状（标称细胞尺寸）、芯材料密度、样本几何形状、样本制备、样本调节、测试环境、样本对齐、预压程序、预压深度、，加载程序和测试速度。

1.1 This test method determines the static energy absorption properties (compressive crush stress and crush stroke) of honeycomb sandwich core materials. These properties are usually determined for design purposes in a direction normal to the plane of the face sheets (also referred to as the facing plane) as the honeycomb core material would be placed in a structural sandwich construction. 1.2 Permissible core materials are limited to those in honeycomb form. 1.3 This test method is not intended for use in crush testing of stabilized honeycomb core materials (for which the facing plane surfaces of the honeycomb core material are dipped in resin to resist local crushing) or sandwich specimens (for which facings are bonded to the honeycomb core material). 1.4 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4.1 Within the text, the inch-pound units are shown in brackets. 1.5 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. 1.6 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 Sandwich honeycomb core materials are used extensively in energy absorption applications, due to their ability to sustain compressive loading while being crushed. Proper design of energy absorption devices utilizing sandwich honeycomb core materials requires knowledge of the compressive crush stress and crush stroke properties of the honeycomb core material. 5.2 The procedures contained within this test method are intended to assess the crush stress and crush stroke properties of the sandwich honeycomb core material under static compressive loading. The dynamic crush stress of the honeycomb core material may vary from that measured under static loading, depending upon factors such as honeycomb core material thickness, core material density, impact velocity, etc. 5.3 This test method provides a standard method of obtaining the compressive crush stress and crush stroke for sandwich honeycomb core material structural design properties, material specifications, research and development applications, and quality assurance. 5.4 This test method is not intended for use in crush testing of stabilized honeycomb core materials (for which the facing plane surfaces of the honeycomb core material are dipped in resin to resist local crushing) or sandwich specimens (for which face sheets are bonded to the honeycomb core material). 5.5 Factors that influence the compressive crush stress and crush stroke and shall therefore be reported include the following: honeycomb core material, methods of material fabrication, core material geometry (nominal cell size), core material density, specimen geometry, specimen preparation, specimen conditioning, environment of testing, specimen alignment, pre-crush procedure, pre-crush depth, loading procedure, and speed of testing.
