European Norm EN 13843: Technical Details

Key Aspects of EN 13843

1. Application:

   • Covers roller skates intended for individuals over 20 kg in weight, typically ranging from recreational users to professional athletes.
   • Includes all types of inline and quad skates.

2. Load and Weight Capacity:

   • Skates are tested under different weight categories to ensure they can withstand maximum user weight without structural deformation or failure.
   • Typical testing categories range from 100 kg to 150 kg, depending on the intended user group.

3. Material Requirements:

   • Skates must be made of durable materials that can resist wear, impact, and fatigue.
   • Corrosion-resistant materials are required for components exposed to moisture, such as wheel bearings and axles.

4. Dynamic Testing:

   • Simulates real-world use, including:
     • Rolling resistance: Ensures smooth and efficient movement.
     • Abrasion resistance: Tests durability of wheels and brake pads.
     • Shock absorption: Assesses how well skates handle vibrations and impacts during use.

5. Wheel and Bearing Standards:

   • Wheels are tested for wear resistance, grip, and rebound properties.
   • Bearings are evaluated for precision, smoothness, and durability under continuous stress.

6. Braking Performance:

   • Roller skates must include a reliable braking mechanism (e.g., heel brakes or toe stops for quad skates).
   • Brakes are tested for effectiveness, longevity, and stability during use.

7. Fastening and Closure Systems:

   • Buckles, straps, laces, and other closure systems must secure the skates firmly to the foot without causing discomfort or coming loose during use.
   • Strength tests ensure the systems do not fail under strain.

8. Impact Resistance:

   • The frame, wheels, and other components are tested to withstand sudden impacts, such as from falls or collisions.

9. Grip and Maneuverability:

   • Skates must provide sufficient grip on smooth and rough surfaces.
   • Tests ensure that the design allows for precise control and maneuverability.

10. Environmental Testing:

    • Skates are subjected to extreme conditions, such as temperature variations and humidity, to evaluate material performance under environmental stress.
