The Drop Test shows the product’s resistance to severe and sudden stresses. To determine the resistance of drums under extreme environmental stress, drums containing a mixture of water and antifreeze are cooled to a temperature of -18 degrees Celsius for 72 hours. The height of the test is determined based on the density of the kept substance. The drums will then be released at two launch angles so that they are under the most stress when they hit the ground. The table related to the density of the kept substance, and the height of the test is given below:
The hydrostatic pressure test is performed on drums that are used to package and transport liquids. This test measures the material’s resistance to internal pressures such as the vapor pressure of volatile liquids and the hydrostatic pressure of liquids inside drums. These pressures can lead to deformation, cracking, and bursting of drums. The test table based on the degree of danger of the stored liquid is as follows:
The materials stored in the drums must not leak during transportation. To ensure that the packing drums do not leak, the lids and valves of the drums must be completely closed, and immersed in a chamber filled with water, and a pressurizing system along with a pressure gauge must be installed on the drums. The amount of applied pressure and its application time according to the degree of danger of the materials stored in the drums are given in the following table:
The storage test is performed to determine the resistance of drums filled with materials during storage. In conducting this test, strict conditions are applied to ensure the safety of the products. Three under-test drums are filled with the liquid that has the highest allowed density, and each of them is under the pressure of the weight of the two drums above it, which are filled with the same liquid. This application of pressure will continue for 28 days at a temperature of 40 degrees Celsius. After completing the test, the three drums under test should not have a significant change in shape.
Chemicals with different degrees of danger can be packed and transported in polyethylene drums. According to the list of transportable chemicals published in the UN standard, there are many specific chemicals with unknown destructive effects on polyethylene that many customers need to pack and transport. To investigate the destructive effect of such materials on the useful life of polyethylene drums, chemical resistance tests are carried out on them. These tests are carried out according to the test method and chemical agents replicated from the requested stored materials and according to the ISO23667:2007 standard.
