According to FAI Sporting Code Section 7 A

8.3 Airworthiness Standards of Other Hang Gliding Equipment

8.3.1 Pilot Suspension Systems The pilot suspension must include a non-metallic load bearing material of minimum 50mm2 cross-section area (normal material Nylon woven webbing with 1000kg breaking strain). The attachment loop must have a backup, which bypasses any mechanical devices and either the main, or backup must be non-metallic. If an integral (one piece) harness suspension/hook-in system is employed, the backup may have a mechanical link which allows it to loop around the keel and attach to itself independently of the primary system
