ISO 13355 Vertical Random Vibration Testing

ISO 13355 evaluates random vibration testing on the transportation of packages. As an ISTA and ISO 17025 certified lab, we realize the importance of ISO 13355 regulatory package testing. Meeting the vertical random vibration standard test requirements can be difficult. We understand the challenges and guide companies through the process.

When packages do not meet the ISO 13355 package integrity and sustainability requirements, Keystone Compliance assists with finding solutions. Our proven process helps avoid product launch delays. Keystone provides the peace of mind that all of your needs will be met. Lastly, we take a consultative approach throughout the entire test program.

Summary of ISO 13355 Transport Package Vibration Testing

The ISO 13355 standard provides test methods for assessing the performance of a package in terms of strength. It also assesses the integrity of a package in terms of the protection it offers to its contents when subjected to vertical vibration.

Scope of ISO 13355 Random Vibration Testing

Note that the ISO 13355 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 ISO regulatory compliance 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 centre of gravity is placed as near as practicable to the centre of the table. The test is then 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 ISO 13355 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. 

The test specimen is usually 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, ensure that the normal method of closure is still employed.

Significance of ISO 13355 Vertical Testing on Transport Packages

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 Compliance is available, a vibration test is more preferable than any fixed or swept frequency vibration test. These are similar to those given in ISO 2247 and ISO 8318.

The test report will reference information such as, but not limited to:

  • 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 in correct interpretation of the packaged product.
  • Any deviations from the test method specified in this international standard.

Expert ISO 13355 Vertical Vibration Lab Package Testing

In addition to ISO 13355 vertical vibration testing, Keystone has a full scope of expertise including vibration, high impact shock, and cold chain. Our team strives to give our customers more time and energy on product development instead of testing. We can accommodate flexible and rigid packages of all sizes, including large pallets.
