19、age 4 EN 12640:2000 BSI 02-2001 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 maximum total mass above 3,5 t and intended for general use. The standard does not apply to: vehic

20、les designed and constructed exclusively for the transportation of bulk materials; vehicles designed and constructed exclusively for the transportation of specific cargo with particular securing requirements. 2 Terms and definitions For the purpose of this standard the following terms and definition

21、s 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 device designed to be attached to the lashing points in order to secure the cargo on the vehicle. T

22、he 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.g. hook, eyelet) 2.3 angle of inclination angle between a vertical line through the lashing point and the direction of appli

23、cation of the lashing force (see Figure 1) 2.4 Angle of rotation smallest angle between a plane through the lashing point parallel to the vehicles longitudinal centre plane and a vertical plane through the direction of application of the lashing force (see Figure 1) 3 Identification To comply with t

24、his 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 for a permissible tensile load of e.g. 20 kN:lashing point EN 12640-20.Page 5 EN 12640:2000 BSI 02-2001 4 Requ

25、irements 4.1 Design requirements 4.1.1 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 loading platform and in the vertical front end wall. In their position of rest they shall not project above th

26、e horizontal level of the loading platform nor beyond the vertical surface of the front end wall into the loading space. NOTE: The recesses in the loading platform required to accommodate the lashing points should be as small as possible. 4.1.2 Lashing points shall be designed to accommodate lashing

27、 forces applied from any direction within the conical area determined as follows (see Figure 1): angle of inclination from 0 to 60; angle of rotation ( ) from 0 to 180 for lashing points with a transverse distance from the side wall and the lashing points 50 mm; angle of rotation ( ) from 0 to 360 f

28、or lashing points within a transverse distance from the side wall and the lashing points 50 mm but 250 mm. 4.1.3 If the lashing point has a round inside profile then the useable inside diameter shall be 40 mm. If it is oval then the clearance in the most unfavourable angle position shall have a widt

29、h of 25 mm and a length of 40 mm. The material cross section of the ring or of an oval link shall fit into a circle with a diameter of 18 mm (see Figure 2). Rings which can move around their complete perimeter when lashed shall not be permitted. 4.1.4 The lashing points shall be designed so as not t

30、o compromise the splash protection and the customs security of the cargo area. 4.2 Number and layout of the lashing points 4.2.1 Lashing points on the floor 4.2.1.1 The number of lashing points shall be determined by the highest result of the following: length of the loading platform (see 4.2.1.2);

31、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 exceeding 2 200 mm there shall be at least 4 lashing points, at least 2 on each side. For vehicles with an effective cargo loading length gre

32、ater than 2 200 mm there shall be at least 6 lashing points, at least 3 on each side.Page 6 EN 12640:2000 BSI 02-2001 4.2.1.3 The lashing points are to be arranged in such a way that: with the exception of the area above the rear axle, the distance between two adjacent lashing points on one side sha

33、ll be not more than 1 200 mm. In the area above the rear axle the distance between two adjacent lashing points shall be as close to 1 200 mm as practicable but in any case shall not be more than 1 500 mm; the distance from front or rear end wall shall not be greater than 500 mm; the distance from th

34、e 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 authorised total mass greater than 12 tonnes, the number of lashing points X shall be calculated by use of the formula (1): 20 1,5 P X (1) In this

35、case P is the inertial force in kN resulting from the maximum payload. b) for vehicles with a maximum total mass exceeding 7,5 tonnes, but not greater than 12 tonnes, the number of lashing points X shall be calculated by using the formula (2): 10 1,5 P X (2) c) for vehicles with a maximum total mass

36、 exceeding 3,5 tonnes, but not greater than 7,5 tonnes, the number of lashing points X shall be calculated by using the formula (3): 8 1,5 P X (3) 4.2.2 Lashing points in the front wall The front wall of a vehicle shall be equipped with at least 2 lashing points mounted symmetrically on either side

37、of the vehicle centre line. The lashing points shall be located such that: a) the vertical distance of the two lashing points measured from the surface of the loading platform is 1 000 mm 200 mm (see Figure 1); b) the distance measured in transverse direction from the side of the front wall should b

38、e as small as possible and in any case not greater than 250 mm.Page 7 EN 12640:2000 BSI 02-2001 4.3 Strength of the lashing points 4.3.1 Each lashing point on the loading platform shall be designed for a permissible tensile load as specified in Table 1.

Upon completion

40、 of the test there shall be no permanent deformation which could impair the function of the lashing point. The strength of the lashing points may also be determined by calculation, provided that the equivalence of the calculation to the reference test method can be demonstrated. 5 Testing 5.1 One la

In the test, the lashing point shall be connected to a suitable lashing hook in accordance with the manufacture

42、rs instructions. 5.2 The direction of application of the test force shall lie within the ranges of angles defined in 4.1.2. One test shall be performed in each of the three most unfavourable directions of application. 5.3 The test force shall be applied for at least 3 min. 5.4 To apply the test forc
