Standard Title
Test Method for Bridge Impact Testing
Overview for ASTM D5265:
Rationale for ASTM D5265:
ASTM D5265 – Test Method for Bridge Impact Testing. A bridged impact is a typical hazard a longer package may experience when shipped with other packages of mixed dimensions. The ability of the packaging to protect the inner component can be verified by simulating this impact under controlled lab conditions. This test method can be ideal when comparing different materials used in design.
According to astm.org,Â
“Significance and Use
4.1Â Materials shipped in elongated packages are liable to damage as a result of impact near their midpoint when only the ends are supported. This type of damage can occur during the shipment of packaging of mixed dimensions. It is particularly prevalent during conveyer line transport and sortation. This test method provides a means of determining resistance to such damage.
Scope
1.1Â This test method is intended to determine the capability of a long package with a narrow cross-section to resist impact near its center when the package is supported only at its ends. This test method allows the user to select from two test options: Option A employs the use of a free-fall drop tester (see Exhibit B), and Option B employs the use of simulated mechanical impact testing equipment (S.M.I.T.E.; see Exhibit A). The two optional procedures are designed to impart the same amount of kinetic energy at impact; therefore, each procedure yields equal damage-producing potential.
1.2Â The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3Â This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.”
This particular ASTM Testing method allows for a choice of using a free-fall drop tester OR a simulated piece of mechanical impact testing equipment.
If a free-fall drop tester is chosen for this testing method, the package is placed on the bottom portion of the actual drop tester machine. The support blocks are placed parallel to each other. The impactor piece is then positioned on the drop table itself. There is a specific height requirement placed on the drop tester above the package being tested. The last part of the test involves the impactor being dropped on the package’s cross-section in order to produce a specific velocity for the dropped package.
The second option uses the simulated mechanical impact testing equipment apparatus. This is where the package is to be tested on the table. The support blocks of the package are to be positioned parallel to each other. The impactor part of the machine is positioned so that it will strike the package with a long edge.
Key Points:
- Utilize this test method to ensure quality control
- Validates material selection during box design
- Verifies packaging materials ability to withstand impact
