The work of preparing

12、 International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liais

13、on with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of te

14、chnical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is dr

BS ISO 27956:2009INTERNATIONAL STANDARD ISO 27956:2009(E) ISO 2009 All rights reserved 1Road vehicles Securing of cargo in delivery vans Requirements and test methods 1 Scope This International Standard applies to vehicle-relevant equipment for the securing of cargo in delivery vans

17、 with a gross vehicle mass up to 7,5 t. This International Standard specifies minimum requirements and test methods for securing cargo in a reliable and roadworthy way, in order to protect occupants against injuries caused by shifting cargo. This International Standard deals with N1 vehicles and N2

18、vehicles up to 7,5 t in accordance with ECE classification1). For vehicles primarily designed for the transportation of cargo and derived from a passenger vehicle (M1), only the requirements concerning the partitioning system of this International Standard apply. NOTE Extreme loads (e.g. vehicle imp

19、acts) that can occur during an accident are outside the scope of this International Standard. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 delivery van vehicle for the transport of cargo, of which the occupant compartment and loading space

20、 form one unit 2.2 lashing point attachment part on the vehicle or an integrated device, to which lashing devices (2.3) can be connected in a form-fit manner and designed to transfer the lashing forces to the vehicle structure NOTE An integrated device can be, for example, a ring, a loop, a tie-down

21、, a hook, an eye, a lug, a hook-in edge, a thread connection, or rails. 2.3 lashing device device that is designed to be attached to the lashing points (2.2) in order to secure the cargo on the vehicle and that consists of a tensioning device, a tensioning element and connections, if required NOTE 1

22、 A tensioning device can be, for example, a belt or a strap. NOTE 2 A tensioning element can be, for example, a wrench, a ratchet, or a spanner. NOTE 3 Connections can be, for example, a hook or an eyelet. 1) See Reference 1. BS ISO 27956:2009ISO 27956:2009(E) 2 ISO 2009 All rights reserved2.4 parti

24、tical longitudinal sections, symmetrical to the left and right of the relevant R-points, with a width of 544 mm per seat and extending over the entire height of the occupant compartment NOTE 1 In the case of a bench, the protection zones between the R-points can overlap. NOTE 2 See ISO 6549 for furt

25、her information on R-points. 2.6 roadworthy design concept aiming at excluding harm to occupants of a road vehicle travelling on public roads under normal conditions of operation, such as full braking, emergency braking, braking in a curve, fast lane changing and driving in a curve NOTE The concept

26、of “harm” includes injuries and fatality. 3 Requirements 3.1 General requirements In order to prevent cargo from penetrating into the occupant compartment, delivery vans shall be equipped with adequate devices to protect the occupants against the cargo. Therefore, protection devices consisting of a

27、partitioning system (see 2.4) and lashing points (see 2.2) shall be provided. 3.2 Partitioning system The partitioning system (see 2.4) shall fully separate the occupant compartment from the loading space, in terms of width and height. In the case of a loading space above the occupant compartment, t

28、he partitioning system may be limited in height to the horizontal separation between the occupant compartment and that loading space. However, in the case of a vehicle having a driver seat only and no passenger seat, the partitioning system does not need to cover the entire width of the vehicle, pro

29、vided that the drivers protection zone (see 2.5) is covered and, in addition, the driver seating position is sufficiently protected against laterally shifting cargo. If there is a gap between the partitioning system and the vehicle body this shall not be more than 40 mm (see Figure 2) without removi

30、ng the covering (or trim), if any. A larger value is permissible in the case of corrugations in the side walls, as well as in order to ensure proper deployment of curtain airbags, if fitted. If the partitioning system consists of a grid or cargo net, a rigid test device (e.g. rod), having a front su

31、rface of (50 10) mm moved in longitudinal direction (parallel to the x-axis of the vehicle), shall not be able to pass such nets or grids in any orientation (rotation around the x-axis). The strength of the entire partitioning system shall be tested in accordance with 4.1.2. The protection zone(s) (

32、see 2.5) of the partitioning system shall withstand testing in accordance with 4.1.3. Each point within the protection zones shall meet the requirements of a test using the type 2 plunger piston (see 4.1.3). If windows or a door are located in the protection zone, such elements shall also withstand

33、this test. The window material may fracture, as long as the deformation criteria given below are met. BS ISO 27956:2009ISO 27956:2009(E) ISO 2009 All rights reserved 3Permanent deformations of the partitioning system up to 300 mm (see Figure 1) are permissible when tested in accordance with 4.1.2 or

34、 4.1.3, as long as such deformations do not cause sharp edges or other deformations which might result directly or indirectly in injuries to the occupants.
