What is IK standard EN/IEC 62262?
Standard EN 62262 specifies the resistance or impact strength of a piece of electrical equipment against external mechanical stress when exposed to special shocks.

How to do an IK test
In the IK test, an impact element is dropped from a well-defined height with a defined weight and shape onto the test site.

IMPORTANT
The EN 62262 standard only specifies the level of impact energy, with the procedure and conditions for the test procedures detailed in standard EN60068-2-75. The following table is NOT in standard EN 62262, but in standard EN60068-2-75.

Exponentially increasing requirement
From IK class IK07, the energy gain per level increases by more than 100%. The exponential increase in impact resistance makes the demands on glasses particularly high and places maximum demands on the material and the integration method. Especially in the extremely robust area of IK10 and IK11, where the impact energy ranges from 20 to 50 joules, every detail counts. The correct integration of the glass for optimal impact resistance is an important prerequisite. We offer you proven integration methods at minimal cost.

Which IK code to choose
Basically, as little as possible but as much as necessary, but often the problems are more complex than the mere fulfilment of a norm.
The key question is what else do you want to achieve?
- Ensure competitive advantage in invitations for tender
- Increase resilience
- Improve product lifespan
- Improve brand image
- Present technology dominance
We will gladly assist you in resolving these issues and quickly and competently provide you with a cost-benefit analysis.
IK impact energy increase
What is a joule?
A Joule is a physical unit of energy. In the IK test, you calculate the impact energy by multiplying the height of fall with the weight of the impact element and the number 10.
Impact energy (W) = fall height (h) * weight (m) * 10
Calculation example: 1.00 m drop height * 1.00 kg mass impact element * 10 = 10 joules impact energy 0.50 m drop height * 2.00 kg mass impact element * 10 = 10 joules impact energy
This calculation is not 100% correct, but is a good and fast approximation.
