ISO 13355 Vertical Random Vibration Testing
ISO 13355 specifies how to carry out random vibration testing on transport packages. As an ISTA and ISO 17025 certified lab, we realize the importance of random vibration testing. Meeting the ISO 13355 vertical vibration requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone Package Testing partners with customers to achieve package compliance. We are in constant communication throughout the test process. Keystone creates an accurate test plan to eliminate expensive over-testing. Lastly, we take pride in our competitive pricing and we offer volume discounts.

Summary of ISO 13355 Transport Package Vibration Testing
ISO 13355 provides test methods for assessing the performance of a package in terms of strength. It also assesses the package in terms of the protection it offers to its contents when subjected to vertical vibration.
The Random Vibration Test is either used as a single test to investigate vertical vibrations, or as a sequence of tests designed to evaluate specimens in a distribution system with vibrational hazards.
Adhering to ISO 13355 helps manufacturers meet industry expectations, build customer trust, and ultimately deliver products that arrive intact and meet customer satisfaction.
ISO 13355 Random Vibration Laboratory Procedures
Note that the test procedures are carried out in the same atmospheric conditions as used for conditioning. This is critical to the performance of the specimen. In other circumstances, the test is carried out in atmospheric conditions similar to those used in conditioning.
The test specimen is first placed in a predetermined attitude on the vibration table. The center of gravity is placed as near as practicable to the center of the table. ISO 13355 is started at 6 dB below the test level to allow the system to equalize the power spectral density profile. Then, it is adjusted to reach the full test level and continued for the predetermined duration.
Whenever possible, the test is performed with spectra obtained from measured data of the particular transportation conditions. Lastly, it is noted that tests may be interrupted at any time to allow for a visual inspection.
ISO 13355 specimen is generally filled with its intended contents. However, simulated or substituted contents may be used. This is provided that the dimensions and physical properties are as close to those of the intended contents.
Ensure that the test specimen is closed normally, as if ready for distribution. If simulated or substituted contents are used, the normal method of closure is still employed.
A random vibration test is a more realistic method in reproducing environmental vibration during transportation than a sinusoidal vibration test. For this reason, if suitable laboratory facilities such as Keystone Package Testing are available, a vibration test is more preferable to any fixed or swept frequency vibration test. These are similar to those given in ISO 2247 and ISO 8318.
After completing the test, a test report is expedited and will reference information such as:
- Number of test specimens used.
- Date, time, location, and specific test engineer.
- Gross mass of the specimen.
- Relative humidity, temperature, and time of conditioning of the vibration testing lab.
- Test results any observations which may assist with the correct interpretation of the packaged product.
- Any deviations from the ISO 13355 standard test method.
Significance of ISO 13355 Vertical Testing on Transport Packages
Vertical package testing allows for the evaluation of the protective capabilities of packaging materials. It helps determine whether the package can effectively dampen vibrations, absorb shocks, and protect the enclosed product from potential harm.
By identifying shortcomings in packaging design, manufacturers can make informed decisions to improve product protection, thereby reducing the risk of damage or loss.
Additionally, package testing is closely linked to product quality and customer satisfaction. By subjecting packages to ISO 13355 testing, manufacturers can identify and rectify design flaws, inadequate materials, or improper package assembly. This proactive approach contributes to overall product improvement, reducing the chances of customer complaints, returns, or damage claims.
Identifying vulnerabilities early in the design phase also allows manufacturers to make modifications that result in more robust packaging. This, in turn, reduces the likelihood of costly product losses, returns, and liability issues.
