6、 Amendment A1:2008 to EN 13411-7:2006 and contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009
7、, 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 Union, it is deemed a
8、 “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). Annexes A and B are informative. Amendments This standard differs from DIN EN 13411-7:2006-09 as follows: a) Subclause 7.3 a) h
9、as been amended. b) The former Annex ZA has been subdived into Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 95/16/EC” and Annex ZB (informative) “Relationsship between this European Standard and the Essential Requirements of EU Di
10、rective 98/37/EC”. c) Annex ZC (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added.

27、uropean Standard is a type C standard as stated in EN 12100. This European Standard has been prepared to provide a means of conforming with the essential safety requirements of the Machinery Directive and the Lift Directive and associated EFTA regulations. The wedge socket concerned and the extent t
28、o which hazards, hazardous situations and events are covered are indicated in the scope of this standard part of the standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the p
29、rovisions of the other standards for symmetric wedge sockets that have been designed and produced according to the provisions of this type C standard. Purchasers ordering to this standards are advised to specify in their purchasing contract that the supplier operates a quality assurance system appli
30、cable to the relevant part of this standard (e.g. EN ISO 9001) to ensure themselves that products claiming to comply consistently achieve the required level of quality. DIN EN 13411-7:2009-04 EN 13411-7:2006+A1:2008 (E) 5 1 Scope This European Standard specifies the minimum requirements for symmetri
31、cal wedge socket terminations for stranded steel wire ropes conforming to EN 12385-5 for lifts. This European Standard covers those symmetric wedge sockets intended for use at temperatures between -20 C and 100 C. This European Standard only covers those symmetric wedge sockets that have welded sock
32、et bodies. An example of the construction and sizes of a symmetric wedge socket is given in informative Annex A. The informative Annex B gives the recommendations for the safe use and inspection of symmetric wedge socket according to Annex A. This European Standard deals with all significant hazards
33、, hazardous situations and events relevant to symmetric wedge sockets for terminations for steel wire ropes, when used as intended and under conditions of misuse which are reasonable foreseeable by the manufacturer. The hazards covered by this European Standard are identified in Clause 4. This Europ
34、ean Standard applies to symmetric wedge sockets, which are manufactured after the date of its publication. 2 Normative references The following referenced documents are indispensable for the application of this document.

44、zardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of steel wire rope termination that require action to eliminate or reduce the risk. In particular, the hazard caused by accidental release of a load, or
45、release of a load due to failure of a symmetric wedge socket, puts at risk, either directly or indirectly, the safety or health of those persons within the hazard zone. Errors in the fitting of accessories can also lead to premature failure and this European Standard contains dimensional and geometr
46、ical requirements to allow correct fit. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for symmetric wedge sockets.
