BS EN 13411-4:2011EN 13411-4:2011 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to
26、 which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When provisions of this type C standard are different from those which are stated in type B standards, the provisions of this type C standard take precedence over the provisions of the other stan
27、dards, for machines that have been designed and built according to the provisions of this type C standard. The methods of socketing described in this standard are based on established procedures and following them is considered to result in a rope termination having an efficiency of 100 % based on t
28、he minimum breaking force of the rope. It is assumed that the socket is: suitable for heating without changing the characteristics of the socket material when the socketing medium is molten metal; strong enough for the rope; and suitable for the purpose for which it is intended. BS EN 13411-4:2011EN
29、 13411-4:2011 (E) 6 1 Scope This European Standard specifies the minimum requirements for the molten metal and resin socketing of steel wire ropes within the scopes of EN 12385-4:2002+A1:2008; EN 12385-5:2002; EN 12385-6:2004; EN 12385-7:2002; EN 12385-8:2002; EN 12385-9:2002 and EN 12385-10:2003+A1
30、:2008. The European Standard is applicable only to those requirements that ensure that the socketing is strong enough to withstand a force of at least 100 % of the minimum breaking force of the rope (i.e. socket termination efficiency factor KT= 1,0). NOTE Rope terminations made by socketing in acco
31、rdance with this European Standard can be used for determining the breaking force of wire ropes in accordance with EN 12385-1:2002+A1:2008, Annex A. Socketing by the methods and materials described in this standard are for use within the temperature limits given in normative Annex E. This European S
32、tandard deals with all significant hazards, hazardous situations and events relevant to metal and resin socket terminations, when they are used as intended and under conditions of misuse which are reasonably foreseeable (see Clause 4). 2 Normative references The following referenced documents are in

46、to eliminate or reduce risk. In particular, the hazard caused by accidental release of a load due to failure of the socketed portion of a socketed rope termination puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. In order to provide the neces
47、sary strength of the socketed portion of a socketed termination, this European Standard gives requirements for the method of socketing to ensure specified levels of performance are met. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific
48、and significant for socketed termination assemblies.
