1.1 本试验方法包括单壁波纹、双壁波纹和实心纤维板箱的规则开槽或特殊开槽类型的内部和外部尺寸的测定。 1.2 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。 1.3 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。 1.4 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====== 4.1 尺寸是盒子一般结构中的重要财产，研究工作、日常控制和验收测试都需要精确的测量方法，以确保符合规范。为了使包装有效地携带和保护其内容物，盒子和内部组件的尺寸必须正确且一致。 尺寸正确、制作精良的盒子可以更容易地手动安装或使用自动设备安装。“方形”盒子（长方体）将更好地堆叠，以接受负载，并提高存储和运输过程中的稳定性。 4.1.1 当盒子里的东西要装满或几乎装满盒子时，盒子的内部尺寸是至关重要的，因为盒子的侧面和顶部几乎没有未使用的空间。胶带法的内部尺寸是盒子设计中最常引用的尺寸值（参见 9.1 和TAPPI T827）。当考虑到评分余量时，可以根据分数到分数的测量结果来估计盒子的内部尺寸（请参见 附录X2 ). 实际内部尺寸可以直接使用箱规法进行测量（请参见 9.2 ). 任何一种方法都可以用于测量内部箱体的尺寸。 4.1.2 当试图根据运输和储存限制来优化运输平台面积和总堆叠高度的使用时，外部尺寸可能是关键的设计标准。在制作常见的示意图框时，外部尺寸也是关键的设计元素。 5. 盒子的外部尺寸可以通过胶带法直接使用外部尺寸进行测量（请参见 附录X1 ). 4.2 测量大量盒子- 该方法确定批次（即生产运行）是否在实践中所示的每个尺寸（长度、宽度和深度）的指定公差范围内 D5118/D5118米 ). 至少测量了五个样本。每个尺寸的测试结果是所有试样上该尺寸的单独测量值（见 9.3 ). 4.3 测量单个盒子- 确定一个特定框是否在每个尺寸的指定公差范围内。每个尺寸的测试结果是该尺寸所有测量值的平均值（参见 9.4 ).

1.1 This test method covers the determination of the interior and exterior dimensions of regular slotted or special slotted styles of single-wall corrugated, double-wall corrugated and solid fiberboard boxes. 1.2 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. 1.3 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. 1.4 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 ====== 4.1 Dimensions are important properties in the general construction of a box, and accurate methods of measurement are required for research work, routine control, and acceptance testing for conformance to specifications. For packages to carry and protect their contents effectively and efficiently, boxes and interior components must be properly and consistently sized. Correctly dimensioned and well-made boxes can be more easily set up by hand or be erected using automatic equipment. “Square” boxes (rectangular parallelepipeds) will stack better to accept load and improve stability during storage and shipment. 4.1.1 Interior dimensions of boxes are critical when the contents of the box are intended to fill or nearly fill the box with little unused side and head space. The inside dimension by tape method are the size values most often cited in box design (see 9.1 , and TAPPI T827). The interior size of a box can be estimated from the score to score measurements when the scoring allowance is taken into account (see Appendix X2 ). The actual inside dimensions can be measured directly using the box gauge method (see 9.2 ). Either method can be used to measure interior box dimensions. 4.1.2 Exterior dimensions may be the critical design criteria when attempting to optimize use of the shipping platform area and overall stack height based on transportation and storage limitations. Exterior dimensions are also key design elements when making common footprint boxes. 5 The exterior dimensions of a box can be measured directly using the exterior dimensions by tape method (see Appendix X1 ). 4.2 Measuring a Lot Quantity of Boxes— This method determines if a lot (that is, production run) is within specified tolerance for each dimension (length, width, and depth as are shown in Practice D5118/D5118M ). A minimum of five specimens are measured. The test result for each dimension is the individual measurements of that dimension on all specimens (see 9.3 ). 4.3 Measuring Single Boxes— Determines if one particular box is within specified tolerance for each dimension. The test result for each dimension is the average of all measurements of that dimension (see 9.4 ).
