WHAT IS IK STANDARD EN/IEC 62262?
IK Standard EN/IEC 62262 defines the impact resistance of electrical equipment. It measures how well the equipment can withstand mechanical shocks from external forces. This rating system helps determine the durability of devices when exposed to specific levels of physical stress, ensuring they can handle various conditions. The IK rating is crucial for assessing the toughness and reliability of electrical devices (Some references are Industrial Monitors,EV Chargers, Outdoor Monitors) in different environments, protecting them from damage caused by accidental impacts.

HOW TO Perform AN IK TEST
To conduct an IK test, an impact element—typically a pendulum or a free-falling object—is dropped onto the material or surface being tested. The impact element has a precisely defined weight and shape, tailored to simulate specific conditions that the material might encounter in real-world situations. The height from which the element is dropped is carefully selected to control the amount of energy delivered upon impact. This energy level is crucial because it directly influences the force exerted on the material.

Impact Energy
The requirements for impact-resistant glasses increase significantly from IK class IK07, where the energy gain per level rises by over 100%. This exponential growth in impact resistance demands extremely durable materials and precise integration methods. In high-end classes like IK10 and IK11, the impact energy ranges from 20 to 50 joules, making every detail crucial for performance. Ensuring optimal impact resistance involves carefully integrating the glass into the structure. Our methods are proven and cost-effective, ensuring maximum durability without breaking the bank. We provide reliable solutions to meet these stringent requirements, ensuring your glasses can withstand the toughest conditions.

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.
