包装 满装的运输包装和单元货物 静载荷法堆积试验

[中文适用范围]： 本国际标准规定了使用静载荷对完整的、装满的运输包装或单元负载进行堆码测试的三种方法。 无论采用哪种方法，该测试均可用于评估包装或单位负载的性能，包括其强度或在堆叠时对其内容物提供的保护。 它可以作为单个测试来研究堆叠的影响（变形、蠕变、塌陷或失效），也可以作为一系列测试的一部分来执行，这些测试旨在测量包装或单位负载承受配电系统的能力，包括堆放危险。 该测试还可用于研究特定装载条件下的性能，例如，当堆叠中的底部包装放置在露天托盘上时；或者当叠加负载的轮廓偏心时，例如当它支撑在放置在集装箱上的单层托盘的支架上时。 出于此类目的，进行测试的三种方法中的一种可能比其他方法更合适。 注：ISO 12048 中给出了使用压缩测试仪进行堆叠测试的方法。 注：1) ISO 12048，包装 — 完整、填充的运输包装 — 使用压缩测试仪进行压缩和堆叠测试。 [外文原描述]： This International Standard specifies three methods for carrying out a stacking test on a complete, filled transport package, or on a unit load, using a static load. Whichever method is employed, the test may be used to assess the performance of a package or a unit load, in terms of its strength or the protection that it offers to its contents when it is subjected to stacking. It may be performed either as a single test to investigate the effects (deformation, creep, collapse or failure) of stacking or as part of a sequence of tests designed to measure the ability of a package or a unit load to withstand a distribution system that includes a stacking hazard. The test may also be used to investigate performance under particular conditions of loading, as, for example, when the bottom package in a stack rests on an open-decked pallet; or when the profile of the superimposed load is eccentric, as when it is supported on the bearers of a single-decked pallet which rests on a container. For such purposes, one of the three methods of carrying out the test may be more suitable than the others. NOTE A method for carrying out a stacking test using a compression tester is given in ISO 120481).
