Gorenje, in its laboratory for transport tests, possesses all the necessary testing for examining developed packaging under real transport loads. Such a transport test represents a suitability trial of packaging units, which can be used to assess the durability of the packaging based on its resistance and protection it provides to the product. For this purpose, the laboratory conducts the following tests:
• Incline impact test according to EN 2244-ISO 2244 standard,
• Vibration test according to EN 22247 - ISO 2247 standard,
• Vertical pressure test according to EN 22234-ISO2234 standard,
• Lateral pressure test according to EN 22874 - ISO 2874 standard,
• Free fall test according to EN 22248 - ISO 2248 standard.
Incline impact test
The incline impact test simulates collisions that can occur during transport (braking, accelerating, collision, etc.) and are also dependent on the type of transport. The test is conducted on a testing device for the incline impact test. During the test, a cart with an upright sample is released (with a predetermined path length) down an incline at an angle of 10 ±1° and collides with a fixed wall, which is positioned at a 90° angle to the plane of descent.
Vibration test
The test is used to assess the durability of packaging in terms of its strength or the protection it provides to the product. The test is carried out on a vibration table, where we simulate vibrations during product transport. It can be conducted as an individual test to study the effects of vibrations, or as part of a testing program to determine the resistance of packaging within a distribution system that includes the hazards of vibrations.
Vertical pressure test
The vertical pressure test is designed to evaluate durability and test the resistance of packaging to vertical loads. The test simulates forces on the product that occur in warehouses due to stacking packages vertically. The test is conducted on a device for testing vertical and lateral pressure. For testing purposes, a sample is vertically inserted between two plates of the compression device (one is fixed, and the other is movable). In this test, the compression of the product is simulated with vertical holders under a predetermined force or until crushing occurs.
Lateral pressure test
The lateral pressure test is designed to assess the durability and test the resistance of packaging to lateral loads. The test simulates forces that arise during the handling of products when loading/unloading them. The test is conducted on a device for testing vertical and lateral pressure. For testing purposes, a sample is horizontally inserted between two plates of the compression device (one is fixed, and the other is movable). In this test, the compression of the product is simulated with lateral holders under a predetermined force or until crushing occurs.
Free fall test
It is carried out on a "free fall" test device. This test simulates manual loading of packaged products. The test sample is lifted and held in a predetermined position at a height. The drop height is the actual distance between the lowest point on the packaging at the time of release and the closest point on the impact surface. The height of the free fall is determined based on the mode of transport (road/rail or sea) and is adjusted according to the weight of the sample. The test also varies slightly depending on the weight of the sample. Accelerations depend on the mass of the sample, the shape of the sample, the height of the free fall, the shape of the fall (edge, surface), the material of the packaging, the construction of the packaging/device, and the center of gravity of the sample.
