Knee protectors for work in the kneeling position according to EN 14404-1

EN 14404-1 specifies the test methods for evaluating knee protectors used as personal protective equipment (PPE) during work in the kneeling position. The standard ensures that such protectors provide adequate protection against impact, pressure, and penetration on the knees during occupational tasks, while maintaining comfort and functionality. The goal is to prevent knee injuries and long-term damage in professions requiring frequent kneeling.

The test methods defined in EN 14404-1 include a series of laboratory evaluations to assess:

• Impact attenuation: The ability to absorb shocks when kneeling on hard surfaces, tested using a falling mass dropped onto the protector.
• Penetration resistance: The ability to prevent objects (e.g., nails, stones) from piercing through the protector under a defined load.
• Force distribution and pressure reduction: Assessment of how well the protector spreads the load over the knee.
• Strap or fixation system performance: Ensuring the protector remains securely in place without impeding mobility.

Tests may vary depending on the type of knee protector (e.g., strap-on, integrated in trousers, or non-fixed pad types). Environmental simulations (like temperature conditioning) may be used to assess performance under different working conditions.
