32、n to be supplied by the manufacturer for descender devices, which include descent lines (hereinafter referred to as lines), intended for rescue and to protect against falls in a rescue system, which is a personal fall protection system. This European Standard does not specify requirements for descen
33、der devices that are used for descending in mountaineering, rope access or work positioning systems. NOTE A descender device which enables the user to rescue himself and which conforms to this European Standard is personal protective equipment (PPE). 2 Normative references The following referenced d

38、lly-operated (type 2) device, including a line, by which persons can, at a limited velocity, rescue themselves or others from a higher to a lower position in such a way that a free fall is prevented NOTE A line could be e.g. wire rope, textile rope, or webbing. 3.1.1.1 automatic descender device (ty
39、pe 1) descender device with a braking system that does not require an intervention by the user once the descent has commenced DIN EN 341:2011-09 EN 341:2011 (E) 5 3.1.1.2 manually-operated descender device (type 2) descender device with a braking system that requires an intervention by the user 3.1.
40、1.3 control device integral element of the descender device normally operated by hand, used to control the velocity of descent down the line 3.1.1.4 panic locking element integral part or function of the control device which stops or slows down the descent and thereby prevents an uncontrolled descen
41、t or a fall if the user panics and operates the descender device beyond its intended control parameters 3.1.2 descent energy energy measured in joules and expressed as W, which results from the product of the descent load, the gravity, the descent height and the number of descents NOTE Descent energ
42、y W = m g h n where W is the descent energy, expressed in joules (J); m is the descent load, expressed in kilograms (kg); g is the gravity 9,81 m/s2; h is the descent height, expressed in metres (m); n is the number of descents. 3.1.3 minimum rated load minimum mass of the person(s), including tools
43、 and equipment, for the descender device, as specified by the manufacturer NOTE Minimum rated load is expressed in kilograms. 3.1.4 maximum rated load maximum mass of the person(s), including tools and equipment, for the descender device, as specified by the manufacturer NOTE Maximum rated load is e
44、xpressed in kilograms. 3.2 Classes Descender devices are classified as follows: a) class A: descent energy W up to 7,5 106 J; b) class B: descent energy W up to 1,5 106 J; c) class C: descent energy W up to 0,5 106 J; DIN EN 341:2011-09 EN 341:2011 (E) 6 d) class D: For only one descent. Descent ene
45、rgy depends on the maximum descent height and the maximum rated load. NOTE In practice, descender devices are subjected to different loads. A descender device for descending, e. g. 100 passengers from a cable car at a height of 100 m, has to meet more severe requirements than a descender device used
46、 by a crane driver to descend by himself from a height of 20 m only once. 4 Requirements 4.1 General 4.1.1 Minimum rated load The minimum rated load shall be specified by the manufacturer. 4.1.2 Maximum rated load The maximum rated load shall be specified by the manufacturer and shall be at least 10
47、0 kg. 4.2 Design, materials and construction 4.2.1 General Materials which may come into contact with the skin of a user shall not be known to, or suspected to, adversely affect user hygiene or health, e.g. cause irritating or sensitization effects, during normal use of the descender device. Descend
48、er devices shall not have sharp or rough edges that may cut, abrade or otherwise damage rope or webbing or cause injury to the user. When descender devices in accordance with this standard have a rescue lifting function, they shall in addition to this European Standard conform to EN 1496:2006, class
49、 A. Connectors shall conform to EN 362. 4.2.2 Lines Lines shall be made from steel or stainless steel wire rope, textile rope or webbing. Lines shall have at least one termination. Line ends that do not have a termination shall have an end stop. The ends of the lines shall be protected against slipping through the descender device unintentionally. Lines including their termination(s) sha
