What constitutes impact elements that comply with standards

Reproducible results

In standard EN 60068-2-75 the impact elements are precisely defined to ensure exact reproducibility and comparability. The standard specifies exactly which material to use, what the shape of the impact elements should look like and how much each test element weighs.

What types of impact elements are there?

Test elements with different properties

There are 3 types of impact elements:

  • Spring hammer
  • Pendulum hammer
  • Vertical hammer

It is not stipulated which impact element used. The spring hammer is due to its compact design and the relatively low mass only able to test IK01 to IK06. The pendulum hammer and the vertical hammer are only used between IK07 and IK10 + due to their high weight.

IMPORTANT

Bullets that only correspond to the correct mass are not standard-compliant impact elements and therefore not permitted for tests according to EN 60068-2-75. There are standards in which steel bullets are specified (e.g. EN60601) but this is explicitly not the case with EN 60068-2-75. The bullet has a different mass diameter ratio as well as a different speed on impact. It cannot be assumed that the same joule number achieves the standard-compliant result if the impact element deviates from the specifications. Especially with bullet diameters that are too small, the impact load is much higher than with correct diameters.

IK10 touchscreen
Impact-resistant rugged touchscreen

IMPACTINATOR® IK10 touchscreens are designed to meet impact resistance with severity level IK10 according to standard EN/IEC 62262. The touchscreen resists 20 joules of impact energy on the IK10 test.

IK10 Monitor Rugged Industrial Monitor
Impact resistant according to EN62262

The impact-resistance of our rugged monitors reliably complies with the IEC 60068-2-75 and IEC 62262 standards with IK10 glass or 20 Joule bullet impact. We offer proven standard solutions as well as special extremely impact-resistant and robust monitors tailored to your application.

IK10 glass Impactinator® Glass
Vandal-proof protective glass

We achieve the reliable IK10 requirement impact resistance with our IMPACTINATOR glass even without a laminated glass construction. For the bullet impact test according to EN/IEC 62262, we achieve values of more than 40 joules for the central impact on 2.8 mm thin glass and exceed the requirements of the EN 60068-2-75 standard by more than 100%.
