BS EN 1496-2017 pdf free download.Personal fall protection equipment — Rescue lifting devices
4 Requirements
4.1 General
4.1.1 A rescue lifting device that is incorporated into other personal fall protection equipment (e.g.retractable type fall arrester) shall meet all the requirements of this European Standard when in the rescue mode.
4.1.2 If the rescue lifting device is permanently fitted or intended to be fitted to a tripod or similar anchor device in accordance with EN 795, the whole unit, i.e. the rescue lifting device and the anchor device combined, shall meet the requirements of this European Standard.
4.2 Ergonomics
When tested in accordance with 5.4 with a mass equivalent to the maximum rated load, but at least 100 kg, the operating force for lifting the test mass shall not exceed 250 N.
4.3 Materials and construction
4.3.1 General
Materials used in the rescue lifting device that may come into contact with the skin of a user shall not be known to cause irritating or sensitization effects during intended use.
When checked in accordance with 5.3, the rescue lifting device shall have no sharp edges and burrs that may cause injury to the user.
4.3.2 Lines
Lines shall be made from textile rope or webbing or from steel wire rope.
NOTE To prevent rotation of the rescuee, swivels can be incorporated in the line.
4.3.3 Ropes and webbings
Fibre ropes shall be of a braided construction or a kernmantel construction. They shall conform to EN 1891:1998, 4.1 and 4.5. If they are of a kernmantel construction, they shall also conform to EN 1891:1998, 4.4.
Wire ropes shall conform to ISO 2232.
Webbings and yarns shall be made of virgin filament or multifilament synthetic fibres, suitable for the use intended. The breaking tenacity of the synthetic fibre shall be known to be at least 0,6 N/tex.
Threads used for sewing shall be physically compatible with the rope or webbing and their quality shall be comparable to those of the rope or webbing. They shall, however, be of a contrasting shade in order to facilitate visual inspection.
4.3.4 Connectors
Connectors incorporated in rescue lifting devices shall meet the requirements of EN 362:2004, except 4.6.
4.4 Function for class A rescue lifting devices
When tested in accordance with 5.8.1, the lifting feature shall still function without failure and the test mass shall be arrested within a vertical distance of 100 mm.
4.5 Dynamic performance and function for class B rescue lifting devices
When tested in accordance with 5.5 with a test mass equivalent to the maximum rated load, but at least 100 kg, the test mass shall be held and the braking force F max shall not exceed 6 kN.
When tested in accordance with 5.8.2, the lifting and lowering feature shall still function without failure and the test mass shall be arrested within a vertical distance of 100 mm.
4.6 Static strength
When tested in accordance with 5.6 with a test force equivalent to 10 times the maximum rated load,but at least 12 kN, the rescue lifting device shall withstand the test force applied for 3 min without tearing or rupture.
4.7 Corrosion resistance
After the test in accordance with 5.7, metal parts shall show no evidence of corrosion that would affect the function of the rescue lifting device (white scaling or tarnishing is acceptable if the function is not impaired).
NOTE Conformity with this requirement does not imply suitability for use in a marine environment.
4.8 Marking and information
Marking of the rescue lifting device shall be in accordance with Clause 6.
Information shall be supplied with the rescue lifting device in accordance with Clause 7.
5 Test methods
5.1 Sampling
At least two test samples shall be provided for the tests.
5.2 Test masses
Three test masses are required:
— test mass A: equivalent to the maximum rated load, but at least 100 kg;
— test mass B: equivalent to 1,5 times the maximum rated load, but at least 150 kg;
— test mass C: 30 kg.BS EN 1496 pdf download.
