Summary of ISO 8318 Vertical Vibration Testing on Filled Transport Packages

ISO 8318 defines two methods for performing sinusoidal vibration tests on complete, filled transport packages or unit loads. Both methods use variable frequencies to evaluate package performance.

Additionally, ISO 8318 assesses how well a unit load protects its contents during vibration exposure. Each method can serve as a standalone test or part of a larger test sequence.

The single test evaluates the effects of vertical vibration. Meanwhile, the test sequence determines whether a unit load can withstand distribution environments that include vibration hazards.

ISO 8318 Random Vibration Testing Procedures

Conditioning

Wherever possible, the test is carried out in atmospheric conditions identical to those used for conditioning. In other circumstances, the test is carried out in atmospheric conditions of those used for conditioning as closely as possible.

Test Procedures

Method 1

First, place the test item on the vibration table in the predetermined orientation. If the test requires a superimposed load, follow the loading procedures in ISO 2234.

Next, expose the packaged product to controlled vertical sinusoidal vibrations. The vibration frequency can vary between 3 Hz and 100 Hz.

Additionally, measure acceleration with an accelerometer attached to the table near the test item. Horizontal frequency components may also occur during testing. However, their acceleration should not exceed 20% of the vertical component value.

Method 2

A resonance search test identifies critical vibration frequencies using one or more complete sweep cycles. The test applies a lower acceleration level, typically between 0.2 g and 0.5 g.

Next, measure and record acceleration responses from both the test item and vibration table. Then, identify the most severe and critical resonances. Typically, the test identifies up to three key resonances.

Finally, perform the endurance test by sweeping through a frequency range within ±10% of the defined resonance frequency. Repeat this process for each additional severe or critical resonance.

Test Report

After ISO 8318 Sine Testing is completed, the data included within the report introduces general and specific information. General details may encompass the date, time, location, and test engineer. More specific data about the testing protocol and package performance may include, but is not limited to:

• A statement to the effect that the results related only to the test item.
• The number of replicate test items tested.
• A full description, including dimensions, structural and material specifications of the test item.
• A description of contents, if simulated or substituted contents were used.
• The duration of the tests.
• The method of restraint.
• The type of apparatus used.
• Any deviations from the test method described in this international standard.

Significance of ISO 8318 Sine Vibration Laboratory Testing

ISO 8318, also known as “Package Testing – Vibration Testing of Filled Transport Packages,” provides a standardized method for evaluating package durability during distribution. The test helps manufacturers assess how packages withstand dynamic transportation stresses.

During transportation, vibrations can cause products and packaging materials to shift, rub, or impact each other. As a result, products may experience damage, breakage, or spoilage. ISO 8318 testing simulates controlled vibration conditions to identify package weaknesses. Manufacturers can then improve designs and enhance product protection.

Additionally, package vibration testing can reduce long-term costs. By identifying issues early, manufacturers can make informed design changes before production. This proactive approach helps reduce product damage, replacements, refunds, and customer complaints.

Furthermore, improved package performance helps prevent supply chain delays. It also reduces costs related to storage, rework, and reshipment.
