Fore word This British Standard has been prepared by Technical Committee AUE/9 It establishes a level of performance for elasticated straps with end attachments and attempts to minimize the risk of inj ury when used It is however acknowledged that these elasticated straps are not designed for use by children and should be clearly labelled to this effect The strength requirement proposed has been deduced by evaluating published anthropometric data and arriving at a compromise between the maximum pull strength and repeated pull strengths It is accepted that elasticated straps are only suited for retaining light loads which have little or no wind resistance and not for any safety critical use A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application C omp liance with a British S tand ard d oe s no t of itse lf confe r immunity from le gal ob ligatio ns S ummary of p age s This

on white using capital and warning markings letters of mm minimum height for the word The products this standard covers are single straps, “Warning”, mm lower case “x” height for the text generally made from braided rubber cord with wire and shall comprise the following: hooks (sometimes known as bungee cords) , or multi “WARNING straps and end attachments (sometimes known as Do not stretch beyond the maximum usable spiders) but may vary in form and material used They may also be supplied as part of another length of 1) system, such as luggage carriers or shopping Keep eyes, face and unprotected areas of the trollies body out of possible rebound path The standard does not apply to straps or assemblies Keep out of reach of children if the overall length is less than 200 mm Do not use to secure heavy or large (wind unextended resistant) loads ” In addition the label shall include the following C onstruction 2.1 information The product shall be free from any accessible burrs, sharp edges or other feature that could cause inj ury in handling 2.2 b) The number and year of this British Standard, If the end attachment is constructed with a locking system then any risk of finger entrapment shall be brought to the attention of the user by inclusion within the instructions, (see clause NOTE 4) The construction of the locking system should be such as to avoid this risk 2.3 a) The UK manufacturer’s, importer’s or distributor’s name or trade mark and address When tested in accordance with Annex A, each elastic strap assembly shall sustain a force of 400 N for If the strap assembly is manufactured in i e BS AU 258: 995 3.2 2) The warnings shall be clearly visible on the product or packaging at the point of sale Instructions for use At the point of sale the instructions for use shall be included with the strap assembly and shall cover at least the following the form of a spider the centre j oining device shall a) The maximum usable length also sustain this force b) Methods of correct attachment, outlining any 2.4 The strap shall stretch to its maximum usable length, as stated by the manufacturer, with the application of a force of less than or equal to 400 N potential risks c) Warnings against potential misuse, as follows ) Not to use worn or frayed straps 2) Not to j oin or knot straps together 3) Not to modify or alter the end attachments
