IK Rating

TL/DR: An IK Rating measures the impact resistance of an enclosure or device on a scale from IK00 (no protection) to IK10 (high impact resistance), as per the IEC 62262 standard. It helps determine durability in harsh environments.

What is an IK Rating?

IK Rating refers to a standardized classification system that defines the level of protection an enclosure offers against mechanical impact. It is established under the IEC 62262 (formerly EN 50102) standard, which assigns a numerical rating to indicate the device’s resistance to impact energy measured in joules.

Understanding the IK Rating Scale

The IK rating scale ranges from IK00 to IK10, with each level corresponding to a specific impact energy. The higher the rating, the better the protection:

IK Rating Impact Energy (Joules) Equivalent Drop Impact
IK00 No protection No impact resistance
IK01 0.15 J 200g from 7.5 cm
IK02 0.20 J 200g from 10 cm
IK03 0.35 J 200g from 17.5 cm
IK04 0.50 J 200g from 25 cm
IK05 0.70 J 200g from 35 cm
IK06 1.00 J 500g from 20 cm
IK07 2.00 J 500g from 40 cm
IK08 5.00 J 1.7 kg from 29.5 cm
IK09 10.00 J 5 kg from 20 cm
IK10 20.00 J 5 kg from 40 cm

Why is IK Rating Important?

The IK Rating helps manufacturers and consumers determine the durability of enclosures for electrical and electronic devices, particularly in high-risk environments. It is critical for:

  • Outdoor & industrial equipment (e.g., security cameras, lighting fixtures)
  • Public infrastructure (e.g., ATMs, ticket machines, public transport screens)
  • Harsh environments (e.g., factories, construction sites)
  • Vandal-resistant applications (e.g., street lighting, access control systems)

IK Rating vs. IP Rating: What’s the Difference?

  • IK Rating: Measures protection against mechanical impact.
  • IP Rating: Measures protection against dust and water ingress.

A product can have both an IK rating and an IP rating to indicate its full level of protection.

Conclusion

If you’re selecting a device or enclosure for rugged conditions, choosing a higher IK rating ensures better durability and impact resistance. Always check the rating to match the level of protection needed for your specific environment.
