1.1 本规范涵盖五种类型和两种类型的敞开式和一种类型，以及一种类型的有盖木箱，其设计净负荷不超过4000 lb[1814 kg]。敞口板条箱适用于装运不易受外力损坏且仅需要有限保护的物品。 1.2 如果需要环境保护，应考虑使用护罩或有盖板条箱。除III型B型板条箱外，本规范中包含的板条箱用于净负载不超过4000 lb[1814 kg]的国内和海外运输。 使用范围应仅限于符合本规范规定类型和等级的尺寸和重量限制的物品 表1 . 1.3 一般来说，A类板条箱的组件较重，能够承受相当严重的搬运和多次装运（重型），而B类板条箱应仅限于对集装箱造成轻微至中度危险的搬运和装运（轻型）。I、IV和V型板条箱为通用型；II型板条箱用于梯子、管子、挤压件或墙板等不需要堵塞、支撑或缓冲的物品； III型、B型板条箱设计用于通道、角钢或其他结构构件等自支撑材料，其中集装箱仅作为更方便堆叠和搬运的方式。 1.4 如果可接受并允许使用其他施工方法或技术（参见 5.1.13 )，由此产生的包装系统应具有与使用这些指定材料和程序产生的性能相同或更好的性能。实践中规定的适当分配周期 D4169 可用于制定比较程序和标准。 1.5 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可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.6 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。 1.7 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。

1.1 This specification covers five types and two styles of open and one type, and one style of covered wood crates designed for net loads not exceeding 4000 lb [1814 kg]. Open crates are suitable for shipment of items, which are not readily susceptible to damage from outside forces, and which require only limited protection against the elements. 1.2 If environmental protection is necessary, use of a shroud or a covered crate should be considered. With the exception of Type III, Style B crates, the crates included in this specification are for use in domestic and overseas shipment of net loads not over 4000 lb [1814 kg]. Use shall be confined to items falling within the dimensions and weight limitations of the types and grades specified in Table 1 . 1.3 In general, Style A crates have heavier components and are to withstand rather severe handling and multiple shipments (heavy-duty), while Style B crates should be confined to handling and shipping that impose only light to moderate hazards on the container (light-duty). Types I, IV, and V crates are general purpose types; Type II crates are designed for items such as ladders, tubing, extrusions, or wallboard which do not require blocking, bracing, or cushioning; and Type III, Style B crates are designed for such self-supporting material as channels, angles, or other structural members where the container serves only as a means for more convenient stacking and handling. 1.4 If the use of other construction methods or techniques is acceptable and permitted (see 5.1.13 ), the resulting packaging systems shall be of equal or better performance than would result from the use of these specified materials and procedures. The appropriate distribution cycle specified in Practice D4169 can be used to develop comparative procedures and criteria. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.6 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. 1.7 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.
