DTU AND REFERENCE STANDARDS

STANDARDS / DTU / QUOTE

ENERGY ABSORBERS The standard NF EN 355 September 2002 sets out the requirements, testing methods, marking, manufacturer information guide and packaging for energy absorbers. Energy absorbers are used as elements or components, either integrated into a lanyard, a belay support or an anti-fall harness, or combined with one of them. The combinations of an energy absorber and a lanyard are sub-systems that constitute one of the fall protection systems covered by EN 363 when they're associated with an anti-fall harness specified in EN 361. The fall protection are specified in EN 353-1, EN 353-2 and EN 360. Principle of standard testing During the test carried out with a 100 kg rigid steel weight or a 100 kg torso mannequin, the Fmax braking stress must not exceed 6 kN and the arresting distance H must be H < 2 Lt + 1.75 m, depending on the total length Lt of the energy absorber with lanyard.

WORK POSITIONING SYSTEMS

NF EN 358 March 2000

NF EN 358 March 2000 applies to belts and lanyards designed for work positioning or restraint. It specifies the requirements, testing methods, marking, and information that the manufacturer must provide.

Principle of standard testing A belt must support a stress of 15 kN applied for 3 minutes without releasing the cylinder.

AUTOMATIC FALL PROTECTION The standard NF EN 360 September 2002 sets out the requirements, testing methods, marking, manufacturer's information guide and packaging for automatic fall protection, which are sub-systems constituting one of the fall protection systems covered by EN 363 when they're associated with an anti-fall harness specified in EN 361. Other types of fall protection are specified in EN 353-1 and EN 353-2. Energy absorbers are specified in EN 355. Principle of standard testing Automatic fall protection with a retractable lanyard made with synthetic fibre rope or strapping must resist a stress of at least 15 kN during tests. Automatic fall protection with a retractable lanyard made with metal cabling must resist a stress of at least 12 kN. During the testing carried out with a 100 kg rigid steel mass, the Fmax braking stress must not exceed 6 kN and the H arresting distance must not exceed 2 m. ANTI-FALL HARNESS The standard NF EN 361 September 2002 sets out the requirements, testing methods, marking, manufacturer's information guide and packaging for anti-fall harnesses. Other types of safety harnesses, specified in other European standards such as EN 358, EN 813 and EN 1497, may be incorporated into the anti-fall harness. Fall protection systems are specified in EN 363. Principle of standard testing During testing on each attachment element with a stress of 15 kN and with a stress of 10 kN, the anti-fall harness must not release the torso mannequin. During testing on each anti-fall attachment element with a torso mannequin weighing 100 kg, the anti-fall harness must resist two successive falls with a free fall distance set to 4 m (first fall with the mannequin falling feet-first, second fall with the mannequin falling head-first) without releasing the mannequin. After each fall, the torso mannequin must be positioned so that its head is upwards and the angle formed by the longitudinal axis of the torso mannequin's back and the vertical must be more than 50°.
