18、N 1497:2007 (E) 4 Introduction A rescue harness conforming to this European Standard can be such that it is either intended to be used only for rescue or it may be incorporated into the design of other types of harnesses for personal fall protection, e.g. a full body harness. A rescue harness is int
19、ended to be worn during normal working activities. EN 1497:2007 (E) 5 1 Scope This European Standard specifies requirements, test methods, marking and information supplied by the manufacturer for rescue harnesses. Rescue harnesses conforming to this European Standard are used as components of rescue
20、 systems, which are personal fall protection systems. Rescue harnesses are not intended to be used as body holding devices in fall arrest systems. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、 body or exert pressure on the body during a rescue NOTE Other straps are called secondary straps. 3.3 attachment point specific connecting point for the attachment to other components, consisting of one or more attachment elements 3.4 rescue system personal fall protection system by which a person
27、can rescue himself/herself or others, in such a way that a fall is prevented 3.5 personal fall protection system assembly of components for protection against falls from a height at work, including at least a body holding device connected to a reliable anchor NOTE Excludes systems for professional a
28、nd private sports activities. 3.6 maximum rated load (for the rescue harness) maximum mass of the person, including tools and equipment, as specified by the manufacturer for the rescue harness EN 1497:2007 (E) 7 NOTE Maximum rated load is expressed in kilograms. 4 Requirements 4.1 Ergonomics 4.1.1 W
29、hen tested and examined in accordance with 5.1, the rescue harness shall be designed so that in the conditions of use for which it is intended: it should offer an acceptable degree of comfort; rescuee is not endangered and safety is not impaired due to a displacement of the straps. 4.1.2 The width o
30、f the primary straps shall be at least 40 mm. 4.2 Materials and construction 4.2.1 General The elements of the harness shall have no sharp edges or burrs that may cause injury to the user. Materials that may come into contact with the skin of a user shall not be known to cause irritating or sensitiz
31、ation effects during normal use of the rescue harness. 4.2.2 Webbings and yarns Webbings and yarns shall be made of 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
32、 shall be physically compatible with the webbing and their quality shall be comparable to that of the webbing. They shall, however, be of a contrasting shade in order to facilitate visual inspection. 4.2.3 Construction 4.2.3.1 General The rescue harness shall be provided with means of adjustment to
33、ensure that it can be correctly fitted to the wearer. The rescue harness may be incorporated within a garment. It shall be possible to inspect visually each element and component of the rescue harness. 4.2.3.2 Attachment The rescue harness shall have at least one attachment point, which is located a
34、bove the users centre of gravity. NOTE Attachment points can be located at the front and/or at the back of the rescue harness. The eye of each attachment element shall be designed so that a rod of a diameter of 25 mm can pass through it. 4.2.3.3 Connectors Connectors shall conform to EN 362. EN 1497
35、:2007 (E) 8 4.3 Dynamic strength When tested in accordance with 5.2 with a torso dummy with a mass equivalent to the maximum rated load, but at least 100 kg, the torso dummy shall be held and no primary strap or attachment element of the rescue harness shall break or rupture. No element of the rescu
36、e harness shall become detached. If the rescue harness has more than one attachment point, the test shall be carried out at each attachment point. 4.4 Static strength When tested in accordance with 5.3, with a test force equivalent to 10 times the maximum rated load, but at least 15 kN applied for 3
37、 min, no primary strap or attachment element of the rescue harness shall break or rupture. No element of the rescue harness shall become detached. If the rescue harness has more than one attachment point, the test shall be carried out at each attachment point. 4.5 Corrosion resistance Metal parts of
38、 rescue harnesses shall be tested in accordance with 5.4. After the test, they shall show no evidence of corrosion that would affect their function (white scaling or tarnishing is acceptable if the function is not impaired). NOTE Conformity with this requirement does not imply suitability for use in
39、 a marine environment. 4.6 Marking and information Marking of the rescue harness shall be in accordance with Clause 6. Information shall be supplied with the rescue harness in accordance with Clause 7. 5 Test methods 5.1 Examination of design Confirm by reference to appropriate documentation, e.g. d
40、ocument of compliance or test report on allergenic substances, and by visual and/or tactile examination of the rescue harness that it meets the requirements of 4.2. Verify the width of each primary strap by measuring it with a steel rule. Verify the opening of the eye of each attachment element by p
41、assing a rod with a diameter of (25 + 10) mm through the eye. Carry out a suspension test with two persons of differing height and weight within the range of 160 cm to 190 cm and within the range of 60 kg to 95 kg, wearing lightweight clothing, and of suitable size for the rescue harness being teste
42、d. The size difference between the two persons shall be at least 15 cm and 20 kg. Following the information supplied by the manufacturer, fit the rescue harnesses to the test persons. Suspend them for a maximum of 4 min clear off the ground by connecting a suitable lanyard or rope to the attachment
43、point of the rescue harness. Movement of the test persons while in suspension is required. Check by visual inspection and interviews with the test persons whether the test persons feel an acceptable level of comfort for at least 3,5 min and that all requirements of 4.1.1 are met.

45、 an impact force of (9 1,5) kN in the first impact force test in that standard. Terminate the rope in loops produced by tying bowline knots (see Figure 3) and ensure the length of the termination loop is a maximum of 200 mm. Adjust the length so that, under a load of (100 + 10) kg, the length of the
46、 test lanyard including the termination loops to be formed at the two ends is (2000 + 1000) mm (see Figure 2).
