EN ISO 5817, Welding — Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) — Quality levels for imperfections (ISO 5817:2003) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 rescue coupler special coupling that enables the hauling and propelling of a failed train unit or train set by another vehicle that is equipped with different coupling design 3.2 rescue vehicle type of vehicle used to rescue a failed train unit or train set 3.3 automatic coupler latch-type automatic coupler allowing the mechanical, pneumatic and in some cases electrical connection between two train units or train sets without manual assistance, also known as "Scharfenberg system type 10" automatic coupler 3.4 draw hook part of a conventional and mechanical manual coupling, also known as UIC draw hook 3.5 main reservoir pipe pipe containing air pressure at a value which is sufficient to supply subsystems including the brake system [EN 14478:2005]
1) UIC 520 will be replaced by a European Standard on draw gear and buffers which is in preparation (prEN 15551 for buffers and prEN 15566 for draw gears). SIST EN 15020:2007+A1:2010

The rescue coupler shall be compatible with:  the Scharfenberg® system type 10 automatic coupler2) having the dimensions specified in Annex A and
 the draw hook having the dimensions shown in Figure C.1. The main dimensions and characteristics of the rescue coupler shall be as given in Annex B. The mass of the complete rescue coupler in its operational condition shall not exceed 50 kg. The rescue coupler shall be able to withstand the following loads without permanent deformation:  maximum tensile load = 300 kN;  maximum compressive load = 250 kN. NOTE There are no fatigue requirements for the rescue coupler. The rescue coupler shall be equipped with handles or components which serve as such for transport and lifting. Material certificates and weld-classes used shall meet current requirements. Welded parts shall be in accordance with prEN 15085 and EN ISO 5817. 4.2 Rescue vehicle characteristics The rescue vehicle characteristics to be taken into account are defined as follows:  connections for electric cables and air pipes on head stocks of locomotives (see Figure C.3);  draw hook (see Figure C.1). Due to different markings located on both sides of the hook it is compulsory to consider a 2059+ mm hook width;  pneumatic coupling for brake pipe and main air reservoir pipe (see Annex D). The rescue coupler pneumatic pipes and their connections shall be provided for a 10 bar pressure.

The coupler shall be secured to the draw hook with a fixing device in such a way that it cannot freely move or come off the draw hook during the rescue operation. Once the rescue coupler is mounted on the draw hook of the rescue vehicle:  the installed rescue coupler shall have at least ± 6° vertical movement from the horizontal during operation;  it shall be possible for the coupler to be adjusted vertically on the draw hook without the need for special tools;  coupling and uncoupling operation shall not require any human presence between the rescue vehicle and the failed train unit or train set whilst either is being moved;  the rescue coupler and the pneumatic hoses shall not limit the maximum lateral movement of the draw hook. 4.4 Coupling conditions 4.4.1 Mechanical coupling The mechanical coupling between the automatic coupler on the failed train set and the rescue coupler on the rescue vehicle shall be automatic. It shall be possible to couple a train set to a rescue vehicle in a 150 m radius curve. For vehicles fitted with automatic couplers, the car builder shall demonstrate:  automatic coupling with a rescue coupler
 uncoupling performance in 150 m radius curve conditions. The rescue coupler shall be designed to ensure that coupling is possible when the height mismatch between the centre lines of the automatic coupler and the draw hook is up to 75 mm. Use of guide horn is not compulsory if this requirement is fulfilled by the vertical
