DISTRIBUTION PACKAGING

Vibration Testing

During transportation, packages will experience vibration due to the fact that all vehicles vibrate during operation.

This vibration is not smooth – it’s rough and rumbling – a mix of various frequencies and amplitudes, and it’s constantly changing.

Utilizing vibration testing techniques to simulate the various shipping methods/vehicles used to transport packaged products worldwide helps us design products, packages, and unit loads capable of being transported without experiencing damage from vibration to the package or, most importantly, to the product itself.

ASTM D4169: Standard Practice for Performance Testing of Shipping Containers and Systems

Standard practice for performance testing of shipping containers and systems. This practice provides a uniform basis of evaluating, in a laboratory, the ability of shipping units to withstand the distribution environment. This is accomplished by subjecting them to a test plan consisting of a sequence of anticipated hazard elements encountered in various distribution cycles. This practice is not intended to supplant material specifications or existing preshipment test procedures.

ASTM D4728: Standard Test Method for Random Vibration Testing of Shipping Containers 

Test methods for random vibration testing of shipping containers. This test method covers the random vibration testing of filled shipping units. Such tests may be used to assess the performance of a container with its interior packing and means of closure in terms of its ruggedness and the protection that it provides the contents when subjected to random vibration inputs.

ASTM D999: Standard Test Methods for Vibration Testing of Shipping Containers

Test methods for vibration testing of shipping containers. These test methods cover vibration tests of filled shipping containers. Such tests may be used to assess the performance of a container, with its interior packing and means of closure, both in terms of its strength and of the protection it provides its contents when it is subjected to vibration such as it experiences in transportation. These procedures are suitable for testing containers of any form, material, kind, design of interior packing, means of closure, and any size and weight. They are not intended for determining the response of products to vibration for product design purposes.

ISO 8318:2000 Packaging – Complete, filled transport packages and unit loads – Sinusoidal vibration tests using a variable frequency

Complete filled transport packaging – Sinusoidal vibration tests using a variable frequency. Performance requirements and tests for means of packaging, packages and unit loads (as required by ISO/TC 122).

ISO 13355:2016 Packaging – Complete, filled transport packages and unit loads – Vertical random vibration test

Complete filled transport packaging – Vertical random vibration test. Specifies a method to carry out a vertical random vibration test on a complete, filled transport package(s) and unit loads using random excitation[1]. This document also provides methods for assessing the performance of a package in terms of its strength or the protection that it offers to its contents when it is subjected to vertical vibration. The test discussed in this document can be performed either as a single test to investigate the effects of vertical vibration, or as a part of a sequence of tests designed to measure the ability of a test specimen to withstand a distribution system that includes a vibration hazard.

ISTA Series 1, 2, 3, & 6

ISTA 1 Series: Non-Simulation Integrity Performance Tests. Challenge the strength and robustness of the product and package combination. Not designed to simulate environmental occurrences. Useful as screening tests, particularly when used as a consistent benchmark over time.

ISTA 2 Series: Partial Simulation Performance Tests. Tests with at least one element of a 3 Series type General Simulation performance test, such as atmospheric conditioning or mode-shaped random vibration, in addition to basic elements of a 1 Series type Non-Simulation Integrity test.

ISTA 3 Series: General Simulation Performance Tests. Designed to provide a laboratory simulation of the damage-producing motions, forces, conditions, and sequences of transport environments. Applicable across broad sets of circumstances, such as a variety of vehicle types and routes, or a varying number of handling exposures. Characteristics will include simple shaped random vibration, different drop heights applied to the sample package, and/or atmospheric conditioning such as tropical wet or winter/frozen.

ISTA 6 Series: Member Performance Tests. Test protocols created by ISTA members to meet their particular purposes and applications. The tests may be completely original, or may be modifications or variations of ISTA Procedures or Projects or other published and accepted tests. ISTA reviews and approves these tests, but primary responsibility rests with the originating members.
