Technical Standard: EN 14404 – Knee Protection

The European standard EN 14404 sets the specific requirements for knee protectors used in occupational settings. A certificated knee protector, such as one that meets the EN 14404 standard, is crucial for safety because it guarantees the product has been rigorously tested for effectiveness, proper design, and long-term durability against the risks of kneeling and knee impact. Certification ensures the knee pads provide adequate shock absorption, protect against sharp objects, prevent penetration, and distribute pressure to prevent long-term wear and tear, reducing the risk of injuries like arthritis, joint pain, and osteoarthritis for workers.

Categories-Types of Knee Protectors

EN 14404 distinguishes four types, depending on how the protection is used:

• Type 1 – Wearable, independent kneepads strapped to the leg.

• Type 2 – Pads inserted into or attached to trousers.

• Type 3 – Loose pads or mats placed on the ground.

• Type 4 – Kneeling systems (e.g. frames, wheeled supports).

Performance Levels-based on penetration resistance + force distribution

• Level 0 – No penetration resistance; force distribution ≤ 30 N (flat surface).

• Level 1 – Penetration resistance ≥ 100 N; force distribution ≤ 30 N (flat surface).

• Level 1U – Penetration resistance ≥ 100 N; force distribution ≤ 30 N (uneven surface).

• Level 2 – Penetration resistance ≥ 250 N; force distribution ≤ 30 N (uneven surface).

Testing Criteria

The standard prescribes a full set of requirements and test methods (referencing EN 14404-1:2024 for methods).

Knee protectors are tested for:

• Impact Absorption: The ability to absorb the force of impacts.

• Penetration Resistance: Protection against sharp or pointed objects from penetrating the material.

• Pressure Distribution: The ability to spread pressure evenly over the entire knee surface while kneeling.

• Dimensions: Minimum dimensions for the protective zones to ensure sufficient coverage and provide proper fit to the user. Not just the ergonomics of the protector itself, but the straps are also part of the testing procedure.

• Water resistance: Whether the inside of the protector remains dry during repeated pressure cycles.
