本试验用来验证待测物在包装状态，模拟在仓储栈板或运输时包装物的堆放，纸箱所能承受的耐压强度水平。考察产品在承受一定时间的垂直方向挤压压力下对产品的保护性能。试验的严苛程度取决于压力值、加载速度和堆码时间。

压缩试验的种类：

a.静态压缩模拟集装箱堆放栈板时，在一定之时间内，承受固定之压力，观察外箱的变形量是否会影响内部产品的外观及电性。

b.动态压缩，固定的压缩速率，即每一单位时间内，施加固定之压力，观察外包装之变形量是否超出限定之要求，借以得知包材可承受之压力并记录此时的负载。

Stacking pressure test

This test is used to verify the packaging status of the object to be tested, and simulate the compressive strength level that the carton can withstand when the packaging is stacked on the storage pallet or transported. To investigate the protective performance of the product under vertical extrusion pressure for a certain period of time. The severity of the test depends on the pressure value, loading speed and stacking time.

Type of compression test:

a. Static compression simulates that when containers are stacking pallets, they should bear a fixed pressure within a certain period of time, and observe whether the deformation of the outer box will affect the appearance and electrical properties of the internal products.

b. Dynamic compression, fixed compression rate, that is, apply a fixed pressure within each unit of time to observe whether the deformation of the outer package exceeds the limit requirements, so as to know the pressure that the package can withstand and record the load at this time.
