ASTM D5277 Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester
Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester
Overview for ASTM D5277:
ASTM D5277 is a test method used to evaluate effects of impacts on a unitized load or package caused during rail switching or pallet marshalling by use of an inclined impact tester.
ASTM D5277 is used to determine the impact resistance of plastic materials when subjected to a falling weight under specified conditions. This test is known as the incline impact test and is used to evaluate the ability of plastic materials to resist impact under various conditions.
The method involves dropping a weight at a specified height onto a sample of the plastic material that is placed at an inclined angle. The weight and angle of inclination are determined based on the type of material and the intended application. The impact energy is calculated based on the weight, height, and angle of inclination.
The results of the test provide information about the ability of the plastic material to withstand impact, which is an important consideration in many applications such as packaging, transportation, and construction. The test is also useful in evaluating the quality and durability of the plastic material. Anyone involved in designing, producing, testing, or using materials or products that are covered by ASTM D5277 (Standard Test Method for Performing Programmed Horizontal Impacts Using an Instrumented Impact Testing Machine) can benefit from this standard. This includes researchers, engineers, technicians, manufacturers, regulators, and consumers in various industries such as automotive, aerospace, construction, electronics, medical devices, and sports equipment.
Overall, the ASTM D5277 incline impact test is a standard method that provides a consistent and reliable way of evaluating the impact resistance of plastic materials.

Rationale for ASTM D5277:
This test method covers a procedure where we would essentially reproduce and compare the shock damage your package product may experience during its shipping journey. Most of the time shock damage can happen involving the shipments going along a rail or involving pallets. A common action during a product’s shipment includes rail switching, where the package may change from one rail to the other depending on its transit route. In this case we would use an incline impact tester to see how the sample packaged product fairs during that shock impact. The machine itself is suitable for simulating and enacting the types of shock pulses experienced by rail switching of rail cars. Standard rail cars may cause shock damage. In rare cases, though, the train cars may have a cushion, which essentially will allow for less shock damage on the packaged product. Impacts are a common occurrence when shipping palletized loads and using this method to evaluate the package’s ability to protect the inner contents is vital. This method is ideal for containers or palletized loads that experience impacts during rail switching or pallet marshalling and is also part of ASTM D4169 – Performance Testing of Shipping Containers and Systems test procedure.
The values that are used and founded in this procedure are in inch-pound units and are to be regarded as standard. The values that are listed and given in paratheses are technically speaking mathematical conversions to SI units that are supplied for information purposes only. It should also be known in part to this standard that it itself does not purport to address all the safety concerns one may face about its use. It is the responsibility of the lab or the essential user to discuss all safety, health, and environmental concerns where applicable. Any special practices and necessities must be decided ahead of time to prevent any limitations of usage or harm.
The method’s use is to evaluate the capability of a container or shipping system to withstand sudden shocks and crushing forces, such as the ones that come from rail switching or pallets marshalling. The level of safety discretion must at least be there due to the use of heavy equipment.
