BS EN 13411-8:2011EN 13411-8:2011 (E) 5 1 Scope This European Standard specifies the minimum requirements for swage terminals and the securing of such terminals by a swaging process to carbon steel rope conforming to EN 12385-4 and EN 12385-5, spiral strand rope conforming to EN 12385-10 and s

23、tainless steel stranded rope. This European Standard is not applicable to spiral rope incorporating full lock wires see EN 12385-10 , nor ropes with coverings and /or fillings (see 3.6.3 of EN 12385-2:2002+A1:2008). This European Standard is applicable to swaged terminations that have a terminal eff

24、iciency factor, KT, of at least 0,9 and are used as part of a wire rope accessory such as a sling, or wire rope assembly that performs a raising, lowering, hauling or supporting function on lifting machinery. This European Standard is applicable to terminals of the following types that are made of c

25、arbon or stainless steel: open swage socket; closed swage socket; swage terminal with thread; swage terminal end stop. This European Standard deals with all significant hazards, hazardous situations and events relevant to swaged terminations, when used as intended and under conditions of misuse whic

26、h are reasonably foreseeable (see Clause 4). This European Standard applies to swaged terminations which are manufactured after the date of its publication. This European Standard is not applicable to swaged terminations used for anchoring ropes to winch drums. 2 Normative references The following r

40、 far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of swaged termination that require action to eliminate or reduce the risk. In particular, the hazard caused by accidental release of load due to failure of the swaged termination puts at

41、 risk, either directly or indirectly, the safety or health of those persons within the danger zone. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for swaged termination assemblies.

In addition, the swaging system shall be designed acc

45、ording to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with in this document. 5.2 Swaging system 5.2.1 General The swaging system designer shall carry out type testing in accordance with 5.2.2. The swaged termination shall be manufactured in accordance

46、 with the swaging system designer(s) instructions. The instructions shall at least cover those items given in 5.2.3 and be supported with a written declaration that the system has passed the type testing requirements of 5.2.2. 5.2.2 Type testing 5.2.2.1 Sampling The following shall apply for each cl

Where the swage terminal design follows a mathematical progression throughout a given size range, rope diameters shall be selected for testing to represent the upper and lower quartiles o

48、f that range. Where the swage terminal design does not follow a mathematical progression through a size range, each rope diameter within that range for which the system is designed shall be selected for testing. For each rope diameter selected in accordance with the above, the rope grade and minimum
