EN 13411-5:2003+A1:2008 (E) 5 Introduction This European Standard has been prepared to provide a means of conforming with the essential safety requirements of the Machinery Directive and associated EFTA Regulations. Purchasers ordering to this standard are advised to specify in their purchasing contract that the supplier operates a quality assurance system applicable to the relevant part of this standard (e.g. EN ISO 9001) to ensure themselves that products claimed to comply consistently achieve the required level of quality. 1 Scope This European Standard specifies the minimum requirements for U-bolt wire rope grips manufactured from ferrous materials and the safe behaviour of eye terminations secured by U-bolt wire rope grips for use as intended by the manufacturer. Suitable uses include suspending static loads and single use lifting operations which have been assessed by a competent person taking into account appropriate safety factors. U-bolt wire rope grips are not suitable for use with spiral ropes. This standard does not cover U-bolt wire rope grips as the primary securing devices on mine hoists, crane hoists or eye terminations for slings for general lifting service. Examples of grips together with fitting instructions are given in informative annexes A and B. The hazards covered by this standard are identified in clause 4. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3.2 grip-secured eye termination grip-secured eye termination: eye termination secured by wire rope grips fitted in accordance with the manufacturer’s instructions 4 List of hazards Accidental release of a load, or release of a load due to failure of a wire rope grip puts at risk either directly or indirectly the safety or health of those persons within the danger zone. Temperature hazard is not covered as in use temperature is limited by the wire rope. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for wire rope grips.

20 000 cycles.
The same grip-secured eye termination subjected to the pulsatory test above shall then be tested in accordance with 6.2.2, after which the grips shall not exhibit any visible cracks, deformation or other damage. 6 Verification of safety requirements 6.1 Qualification of personnel All testing and examination shall be carried out by a competent person. 6.2 Type testing 6.2.1 General In order to prove the design, material and method of manufacture, testing shall be carried out on each class of rope for which the grips are designed. The grade of the rope shall be the highest for which the grips are designed.
Where grips are intended for use with single layer ropes with a fibre core and a steel core, testing shall be carried out on both.
At least three assemblies having a grip-secured eye termination at one end shall be tested.
NOTE The number of tests is regarded as two for assemblies having grip-secured eye terminations at both ends. SIST EN 13411-5:2004+A1:2008
