43、erms of nominal rope diameter, strand construction, minimum breaking force, direction and type of lay, wire grades, measured rope diameter and measured lay length. EN 12927-3:2004 (E) 7 4.2.2 Hazard scenarios Especially the following events may lead to hazardous situations, which may be avoided or l

44、imited by the requirements of this document: a) slipping apart of the two rope ends connected by a long splice may lead to a failure of the long splice; b) slipping or malfunction of the grip in the splice area can lead to insufficient attachment of the grip. 4.2.3 Safety measures a) The risk of sli

45、pping apart of the spliced rope ends may be reduced by a correct correlation of geometrical characteristics of the two ropes connected by the splice, by selecting the splice geometry in accordance with this standard and by selecting the correct auxiliary (wrapping) material. b) The risk of an insuff

46、icient grip attachment may be reduced by applying the diameters overall to the splice in accordance with this standard. 5 Long splicing requirements 5.1 General A spliced connection is admissible only if during operation the rope safety factor does not exceed 20 at any section of the cableway and is

47、 not less than the values set-up in EN 12930. Splicing shall be performed by a competent person, the splicer, following a written technical procedure. The splicer shall be qualified by knowledge and practical experience and shall be capable of assessing the quality of the splice in relation to the s

48、trength and function of the rope. To avoid affecting the results from any subsequent magnetic rope testing (MRT), the rope splice shall not contain any magnetic material other than the rope itself. If there are two or more splices they shall be durably marked according to their age. 5.2 Splice geometry The overall splice length and the length of the tails shall be at least: Length Tails Safety factor 15 1200 60 Safety factor 15 SF 20 1500
