TAPPI T 804 om-20用于测量瓦楞或实心纤维集装箱的抗冲击能力 外部压力。该方法可以以多种方式应用。对于质量研究，通常需要测试 空容器。对于涉及内填料（角柱等）的抗压性研究，可在内填料就位的情况下进行试验。如果要研究整个包装的整体性能，则可使用装有其内容物的容器和所有内包装进行试验。在许多包装中，内容物和内包装共同承载一部分货物。可将容器放置在机器中，以便在以下方向上测试抗压性: 与容器使用相关，包括顶部- 到底部、端到端或侧到侧。

TAPPI T 804 om-20 is used for measuring the ability of corrugated or solid fiber shipping containers to resist external compressive forces.The method may be applied in a number of ways. For quality studies, it is usually desirable to test the empty container. For the study of compression resistance where inner packing (corner posts, etc.) is involved, tests may be made with the interior packing in place. If overall performance of the entire pack is to be studied, the test may be conducted with the container loaded with its contents and all inner packing. In many packs the contents and inner packing share in carrying a portion of the load.The container may be positioned in the machine so as to test the compressive resistance in a direction that is relevant to the container's use including top-to-bottom, end-to-end, or side-to-side.
