EN 12927-6:2004 (E) 5 1 Scope This part of EN 12927 specifies the safety requirements applicable to discard criteria for steel ropes for passenger transportation by rope. This standard is applicable to the various types of installations and takes into ac
28、count their environment. This part of EN 12927 applies to all types of ropes and end fixing used in cableways for passenger transport. Some requirements concern synthetic ropes. Requirements relating to the protection of workers are not included in this part of EN 12927. This part of EN 12927 is not
29、 applicable to installations for the transportation of goods nor to inclined lifts. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、e repaired (see EN 12927-3 and EN 12927-7). 3.2 reference length the length of rope over which the value of a specified characteristic is measured or assessed e.g. 6 x d (6 x nominal diameter of the rope) 3.3 loss in metallic area (lma) reduction in area expressed as a percentage of the nominal meta
42、llic cross-sectional area of the new rope, taking into account the effects of broken wires and the effect of corrosion and wear 3.4 main body of the rope all the length of rope excluding any sections in end fixing or long splice 3.5 additional tensioning device additional device intended to hold the
43、 tension in a rope in case of failure of the main tensioning device 4 Symbols d nominal diameter of the rope. EN 12927-6:2004 (E) 7 5 General requirements 5.1 Application of this standard The requirements of this document apply to all installations along with those of EN 1709, EN 1908, EN 1909, EN 1
44、2397, EN 12408, EN 12927-1, EN 12927-2, EN 12927-3, EN 12927-4, EN 12927-5, EN 12927-7, EN 12927-8, EN 12929-1, EN 12929-2, EN 12930, EN 13107, EN 13223, EN 13243, prEN 13796-1, prEN 13796-2 and prEN 13796-3. 5.2 Safety principle 5.2.1 General Irrespective of whether the rope is inspected by MRT or
45、visual means, the same wire broken in several places over the stated reference length shall be regarded as a single broken wire. Loose wires and wires repaired by welding, brazing or gluing shall be regarded as broken wires. Ropes shall be discarded if their condition cannot, or can no longer, be as
46、sessed with the current methods of inspection. After an external event (lightening, derailment,.etc.) the discard criteria shall be checked by a competent person before further operation. 5.2.2 Hazard scenarios Especially the following events may lead to hazardous situations which may be avoided or
47、limited by the requirements of this document: a) excessive decrease of the metallic cross sectional area may lead to the breakage of the rope; b) fatigue breaks, corrosion and wear may lead to a failure of end fixing and of tension ropes; c) deterioration/damaging of the structure of the rope can le
48、ad to deropement or to insufficient attachment of the grip; d) slipping apart of two rope ends connected by a long splice may lead to a failure of the long splice. 5.2.3 Safety measures a) The decrease of the metallic cross sectional area shall be limited by repair according to EN 12927-7 or by discarding the rope according to this standard; b) the risk of a failure of end fixing and of tension ropes may be reduced by discarding by timeout (hours or years) according to this standa
