The CE standard EN 813 is a European standard that specifies the requirements for sit harnesses used in fall arrest, work positioning, and rope access work. Here’s a breakdown of its key points:
Overview of EN 813
EN 813 focuses specifically on sit harnesses—harnesses designed to support the user around the waist and thighs, providing stability while allowing the wearer to move and work hands-free.
Key Requirements
- Design and Structure:
- Sit harnesses under EN 813 should have a low attachment point at the front of the waist. This is typically a D-ring or other secure attachment designed for a lanyard or rope.
- The harness should allow for comfort and freedom of movement, especially for prolonged use in seated positions (e.g., for rope access work).
- Performance Testing:
- Sit harnesses must pass dynamic and static load tests to ensure they can withstand forces encountered during falls or sudden loading.
- Tests evaluate strength, durability, and security of the attachment points and harness material.
- Materials and Durability:
- All materials must be durable, resistant to abrasion, and able to withstand environmental factors like UV exposure and moisture.
- The harness webbing, stitching, and hardware (buckles, rings) need to be made from materials that won’t degrade easily over time.
- Comfort and Ergonomics:
- Given the sit harness’s focus on comfort, it should distribute weight evenly to prevent pressure points during long periods of suspension.
- Some designs may incorporate padding or ergonomic shapes to improve comfort.
- Labeling and Marking:
- Each harness should be marked with the CE symbol, standard reference (EN 813), the manufacturer’s details, and batch/serial number.
- The label must also indicate maximum load capacity and any specific use instructions or warnings.
- Application:
- Sit harnesses under EN 813 are mainly for rope access, work positioning, and certain types of rescue work but not for fall arrest as the sole harness.
- They’re often combined with a chest harness or other components to create a full-body harness for fall arrest applications (meeting EN 361).
Why EN 813 Compliance Matters
EN 813 compliance ensures that the sit harness is safe and reliable for professional use. It’s essential for workers in construction, window cleaning, and rescue operations where they need to be suspended for extended periods. This standard provides confidence in the harness’s durability, comfort, and performance under working conditions.
