Page 3 EN 12640 : 2000 1 Scope This Standard specifies the minimum requirements and test methods for lashing points fitted to commercial vehicles and trailers with flatbed body construction of max
16、imum total mass above 3,5 t and intended for general use. The standard does not apply to - Vehicles designed and constructed exclusively for the transportation of bulk materials; - Vehicles designed and constructed exclusively for the transportation of specific cargo with particular securing require
17、ments. 2 Terms and definitions For the purpose of this standard the following terms and definitions apply : 2.1 Lashing point Securing device on a vehicle to which a lashing may be directly attached. A lashing point can be e.g. an oval link, a hook, a ring, a lashing shoulder. 2.2 Lashing equipment
18、Device designed to be attached to the lashing points in order to secure the cargo on the vehicle. The lashing equipment consists of tensioning elements (e.g. belt, chain, cable), tensioning device (e.g. wrench, ratchet, spanner, tension jack) and connections, if required (e.9. hook, eyelet). 2.3 Ang
19、le of inclination The angle between a vertical line through the lashing point and the direction of application of the lashing force (see figure 1). 2.4 Angle of rotation a The smallest angle between a plane through the lashing point parallel to the vehicles longitudinal centre plane and a vertical p
20、lane through the direction of application of the lashing force (see figure 1). 3 identification To comply with this Standard the lashing points shall be identified by reference to the number of this Standard and the permissible tensile load according to 4.3. EXAMPLE Identification of a lashing point
21、 for a permissible tensile load of e.g. 20 kN: Lashing point EN 12640 -20. Page 4 EN 12640: 2000 4 Requirements 4.1 Design requirements 4.1. I Lashing points shall be designed so that they transmit the forces they receive into the structural elements of the vehicle. They shall be fixed in the loadin
22、g platform and in the vertical front end wall. In their position of rest they shall not project above the horizontal level of the loading platform nor beyond the vertical surface of the front end wall into the loading space. NO TE The recesses in the loading platform required to accommodate the lash
23、ing points should be as small as possible. 4.1.2 the conical area determined as follows (see figure 1): Lashing points shall be designed to accommodate lashing forces applied from any direction within - angle of inclination from O“ to 60“ - angle of rotation (a) from O“ to 180“ for lashing points wi
24、th a transverse distance from the side wall and the lashing points I 50 mm; - angle of rotation (a) from O“ to 360“ for lashing points within a transverse distance from the side wall and the lashing points t 50 mm but 5 250 mm. 4.1.3 If the lashing point has a round inside profile then the useable i
25、nside diameter shall be 2 40 mm. If it is oval then the clearance in the most unfavourable angle position shall have a width of 2 25 mm and a length of 2 40 mm. The material cross section of the ring or of an oval link shall fit into a circle with a diameter of I 18 mm (see figure 2). Rings which ca
26、n move around their complete perimeter when lashed shall not be permitted. 4.1.4 security of the cargo area. The lashing points shall be designed so as not to compromise the splash protection and the customs 4.2 4.2. I 4.2.1.1 The number of lashing points shall be determined by the highest result of
27、 the following: Number and layout of the lashing points Lashing points on the floor - length of the loading platform (see 4.2.1 2) - maximum distance between lashing points (see 4.2.1.3) - permissible tensile load (see 4.2.1.4). 4.2 1.2 For vehicles with an effective cargo loading length not exceedi
28、ng 2200 mm there shall be at least 4 lashing points - at least 2 on each side. For vehicles with an effective cargo loading length greater than 2200 mm there shall be at least 6 lashing points - at least 3 on each side. Page 5 EN 12640 : 2000 421.3 The lashing points are to be arranged in such a way
29、 that - with the exception of the area above the rear axle the distance between two adjacent lashing points on one side shall be not more than 1200 mm. In the area above the rear axle the distance between two adjacent lashing points shall be as close to 1200 mm as practicable but in any case shall n
30、ot be more than 1500 mm; - the distance from front or rear end wall shall not be greater than 500 mm; - the distance from the side walls of the loading area should be as small as possible and in any case shall not be greater than 250 mm. 4.2.1.4 a) For vehicles with a maximum authoriced total mass g
