It is a whole object, the mass is at least 50 times the mass of the test sample B. There must be a large enough area to ensure that the test sample falls completely on the impact table C. The horizontal height of any two points on the impact table must not exceed 2mm D. When a static load of 10kg is applied to any area of ​​100mm2 on the impact table, its deformation shall not exceed 0.1mm. After a product is packaged, it may be dropped during the handling process, and the resulting impact will damage the product. Therefore, general production companies will perform a drop test on the packaged items. The height of the drop is mainly determined by the weight of the product, but according to various standards, samples of the same weight may have different heights, so we must be clear about what standard to use before conducting the test.
