4 Requirements
4.1 General
The following minimum requirements regarding the rigidity of tarpaulins and their attachments shall be met.
4.2 Materials
The quality of the materials used for tarpaulins shall be such that the resulting product will conform to the requirements defined in Table 1 and ensure uniformity of the performance.
4.3 Construction of tarpaulin
If the tarpaulin is composed of several pieces, the connections of the pieces shall be such that the same requirements (see Table 1) are met as for the material.
4.4 Divided tarpaulins
Vertically divided tarpaulins shall only be used if their conjunction matches the requirements of Table 1. Openings are only valid if the conjunction corresponds to the application specific requirement
of the transport carrier and the mission critical tightness against external influences is guaranteed. See Figure 1.
4.5 Fixation of tarpaulins
To fulfil customs regulation, with the exception of the area around the stanchions, the distance between eyelets shall be no greater than 200 mm (horizontally and vertically). In the region of the stanchions, the distance may increase but shall be no more than 300 mm. The loops both vertical and horizontal shall always be arranged in line. Zigzag attachments (sling-clasp) shall not be acceptable.
The tarpaulin shall be secured with a suitable rope between the swap body brackets and the eyelets of the tarpaulin. Additional anchorings of the tarpaulin (for example: tension triangles) are valid.
The following ropes are permissible:
— hemp or sisal ropes not less than 8 mm in diameter which shall be covered with an additional transparent plastic sheath;
— steel wire ropes not less than 3 mm in diameter.
Steel wire ropes with additional transparent plastic sheath may be used.
For other cases of application, the attachments have to be performed in this way that they match the application specific requirements.BS EN 12641-1 pdf download.
