7、on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Un
8、ion, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”).

29、tial 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 e
30、nsure 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
31、 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 stand
32、ard 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 i

40、ue 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
41、 by risk assessment as being specific and significant for wire rope grips.

The grade of the rope shall be the highest for which the grips are designed. Where grips are intended for use with single layer
48、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. DIN EN 13411-5:200

The angle subtended by the eye shall not exceed 30. The minimum length of free rope between the outer grips for assemblies having grip-secured eye terminations at each end shall be at least 30d, where d is the nominal rope diameter. The test machines used in the tests specified in 6.2.2 and 6.2.3 shall conform to EN ISO 7500-1. Any change of design, specif
