ISO 2247 Low-Frequency Vibration Testing

ISO 2247 Vibration Package Tests at Low-Frequency Vibrations

ISO 2247 assesses the performance of packages when subjected to low-frequency vibration. As an ISTA and ISO 17025 certified lab, we realize the importance of package testing. Meeting the ISO 2247 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 provides comprehensive reports shortly after completion of the testing. When packages do not meet the requirements, we assist with finding solutions.

Summary of ISO 2247 Vibration Package Testing

These tests are performed to investigate the effects of low-frequency vibration. ISO 2247 can also be used to measure the ability of a package or unitized load to withstand a distribution system that includes a vibration hazard. These hazards may be at a low frequency or repetitive shock.

The following documents contain provisions that constitute this International Standard.

  • ISO 2206, Packaging – Complete, filled transport packages – Identification of parts when testing
  • ISO 2233, Packaging – Complete, filled transport packages and unit loads – Conditioning for testing
  • ISO 2234, Packaging – Complete, filled transport packages and unit loads – Stacking tests using static load

ISO 2247 Filled Transport Packages and Unit Load Testing Procedures

Conditioning

First, the required conditioning for the test specimen is noted throughout the test processes. The test specimen shall be conditioned per ISO 2233 Conditioning of Packages for Testing.

Procedures

There are two common procedures when dealing with vibration testing at low frequencies. Wherever possible, both tests are conducted in atmospheric conditions identical to those used for conditioning.

These conditions are vital for the materials or application of the test specimen. However, if these conditions are unavailable, the conditioning is carried out as closely as possible.

After, the test specimen is placed on the vibration table with a predetermined orientation. The center of its lowest face or its center of gravity is placed as near as practicable to the center of the table. If the test specimen is not secured to the table, it may be fenced.

If a stacked load is required, the procedure shall comply with ISO 2234 Stacking Tests Using a Static Load.

Next, the test specimen vibrates using either test method A or B.

Method A – The vibration table operates at a selected acceleration level between 0,5 g and 1,0 g.

The test specimen should not be separated from the table. Lastly, the test is performed at a peak-to-peak displacement.

Method B – The vibration table operates at a selected acceleration level such that the test specimen is separated from the table. This causes repetitive shock.

The desired amplitude is then selected. The vibration of the specimen starts at a frequency of 2 Hz and slowly increases. This occurs until the specimen repeatedly separates from the vibration table.

Test Report

The test report includes general information such as the date, time, location, and test engineer. Other more specific information written within the report includes, but is not limited to:

  • A reference to this international ISO 2247 standard
  • A full description of the test specimen and its reinforcing arrangements
  • A description of the contents and if simulated or substituted contents is used
  • Whether a superimposed load is used
    • If so, the mass of the load and the time during which the test specimen is under load
  • The vertical motion of the table, whether linear, linear inclined, circular, elliptical, or other,
  • The vertical and horizontal peak-to-peak displacement
  • The fixed frequency and duration of the test
  • Any deviations from the test method described in this international standard
  • A record of the result, including any observations which assist in the correct judgement of the results

Significance of ISO 2247 Vibration Testing at Low Frequencies

Vibration testing plays a crucial role in various environments, ensuring the reliability and durability of products and systems. ISO 2247 is an industry standard that specifically addresses vibration testing at low frequencies.

By subjecting the structure to controlled vibrations, it is possible to identify potential weaknesses, resonant frequencies, and structural flaws. This information helps engineers and designers improve the structural integrity and performance of buildings, bridges, and other infrastructure.
