IEC 60068-2-64 Vibration Package Integrity Testing

IEC 60068-2-64 Vibration Testing

IEC 60068-2-64 evaluates how specimens resist dynamic loads subjected to vibration testing without degradation of its integrity. As an ISTA and ISO 17025 certified lab, we realize the importance of IEC 60068-2-64 vibration testing. Meeting the IEC random vibration testing requirements can be difficult. We understand the challenges and guide companies through the process. 

Keystone Package Testing takes a consultative approach throughout the entire test program. Our proven process helps avoid product launch delays. We have a reputation of helping customers achieve their package certifications. When packages do not meet the requirements, Keystone assists with finding solutions.

Summary of IEC 60068-2-64 Random Vibration Testing

The IEC 60068-2-64 package testing standard addresses the structural integrity of packages during the transportation life cycle. The transit testing standard demonstrates the adequacy of equipment to resist dynamic loads under random vibration. Units that meet the test requirement have no or acceptable degradation of function or structural integrity.

Broadband random vibration may be used to identify a number of issues. These issues include accumulated stress effects and the resulting mechanical weakness. Another issue could be the degradation in the unit’s specified performance.

IEC 60068-2-64 transit testing is applicable to specimens that may be subjected to the vibration of a stochastic nature. This vibration can result from transportation or operational environments. For example, in aircraft, space vehicles, and land vehicles.

The methods and techniques in this integrity standard are based on digital control of random vibration. It permits the introduction of variations to suit individual cases if these are prescribed by the relevant specification.

Compared with most other IEC and package integrity standards, this test is not based on deterministic but on statistical techniques. Broad-band random vibration testing is therefore described in terms of probability and statistical averages.

It is emphasized that random testing always demands a certain degree of engineering judgment, and both supplier and purchaser should be fully aware of this fact. The writer of the relevant specification is expected to select the testing procedure and the values of severity appropriate to the specimen and its use.

Scope of IEC 60068-2-64 Package Integrity Compliance

The IEC 60068 test method is based primarily on the use of an electrodynamic or a servo-hydraulic vibration generator with an associated computer-based control system used as a vibration testing system.

This compliance test standard is primarily intended for unpackaged specimens. It is also intended for items in their transportation container when the latter may be considered as part of the specimen itself. However, if the item is packaged, then the item itself is referred to as a product. In this case, the item and its packaging together are referred to as a test specimen.

Some specimens can be subjected to the vibration of a combination of random and other forces. These can result from transportation or real-life environments. Examples include aircraft, space vehicles, and items in their transportation container. In these cases, testing with pure random may not be sufficient

IEC 60068-2-64 compliance testing follows a specific test sequence. This sequence is as follows:

  • Initial vibration response investigation, if prescribed;
  • Low-level excitation for equalization before proceeding to the full level test in one continuous mode;
  • Random vibration testing;
  • Final vibration response investigation, if prescribed.

The test item is to be excited in each of the preferred testing axes. The order of the testing along these axes is not important unless prescribed by the relevant specification. If the specimen is sensitive to gravity, then vibration may only be applied in its normal service position and shall be prescribed by the relevant specification. An example includes a mercury tilt switch.
