Testing that Reaches the World

Crush testing simulates real-world scenarios where batteries may be subjected to mechanical stress.  The Clark’s test engineering team provides crush testing services to help to prevent failures that could lead to fires or explosions.

Many industries require compliance with UN 38.3 crush testing standards. Our testing services ensure that your batteries meet these essential safety requirements of UN 38.3 along with IEC 62133.

Mechanical crush testing helps to understand how batteries will respond to stress conditions applied by crush testing allowing for design improvements, enhancing overall product reliability.

Clark Crush Testing Services

1. Test Setup: We prepare battery samples according to various industry standards and product specifications, ensuring accurate and consistent testing conditions.
2. Crush Test Execution: Batteries are subjected to specified forces to simulate crushing impacts. We monitor performance and observe any signs of failure, such as thermal runaway or leakage.
3. Data Analysis: Post-testing, we conduct a detailed analysis of the results, providing insights into battery behavior under stress and identifying areas for improvement.
4. Compliance Reporting: We generate comprehensive reports that detail the testing process and results, ensuring you have the documentation needed for regulatory compliance.

Industry Standards for Crush Testing

• UN 38.3 standard for testing lithium-ion batteries that are transported. The crush test involves gradually crushing a battery between two flat surfaces until one of the following conditions is met:
  • The applied force reaches 13 kN +/- 0.78 kN
  • The voltage drops by 100 mV or more
  • The cell is deformed by 50 % or more of its original thickness
• IEC 61960 - This standard applies to secondary lithium batteries and cells used in portable devices, consumer electronics, and medical devices.
• UL 1642 and UL 2054 - These standards from Underwriters Laboratories (UL) cover the safety of lithium-ion cells and multi-cell battery packs, respectively.
• IEEE 1625 and IEEE 1725 - These standards from the Institute of Electrical and Electronics Engineers (IEEE) apply to rechargeable batteries used in portable computing and cellular telephony, respectively.
• IEC 62133-2 - This standard was adopted by the European Union in 2021, and all new portable lithium-ion batteries in the EU must comply with it.
• ANSI/UL 62133-2 and CSA C22. 2 No. 62133-2:20 - These standards have been adopted by the US and Canada, with transition timelines for enforcement varying between NRTL
