Page 3 EN 12195-2 : 2000 Introduction This European Standard has been prepared to be a harmonized standard to provide conformity of the safety requirements for web lashings on the European Market and thus to e
17、nable free trade. The extent to which hazards are covered is indicated in the Scope of the Standard. In addition web lashings for securing of loads on vehicles shall conform as appropriate to EN 292 for hazards which are not covered by this Standard. 1 Scope This Part of EN 12195 - specifies safety
18、requirements for web lashing made from man-made fibres with flat woven webbings for multiple use and of lashing combinations with woven webbings for the safe surface transport of goods on road vehicles, e.g. trucks and trailers which are used on roads or located on vessels or on rail Waggons and/or
19、combinations thereof; - includes only tensioning devices to be hand driven with a maximum hand force of 500 N; - specifies methods for testing of web lashing for securing of loads; - deals with the significant hazards which could occur when web lashings are in use as intended and under conditions fo
20、reseen by the manufacturer (see clause 4 and Annex A): - includes composite load restraint assemblies also for the same purpose as above. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

If removable hand cranks are used they shall be secured against accidental detachment. The backlash of the lever end of the
39、tensioning device (in case of winches, the crank) under a tensile force shall not exceed 150 mm when opened. Tensioning devices shall be designed to exclude an unintentional release of the tension in the lashing. With a force corresponding to 0,3 LC applied to the web lashing, it shall be possible t

45、safety to the area of textile webbing in contact with the tensioning device; - the tensioning device shows no sign of permanent deformation, cracks, flaws or other defects likely to affect safety when examined by a competent person. If removable handcranks are used they shall be secured against unin
46、tended detachment when loaded. The tensioning device (ratchets) shall require positive action to release the tension in the web lashing. The tensioning device shall take a minimum of 2 % turns of textile webbing around the slotted pin. 5.3.2.2 Cyclic loading test of tensioning devices and tension re
47、taining devices Tests on cyclic loading shall be carried out on web lashings of LC 2 5 kN. The web lashing shall resist 100 alternations at a frequency not higher than 0,4 Hz between 0,2 LC and 1,0 without settling more than is given in Table 1 (see also 6.6).
