21、dard has been prepared to be a harmonized standard to provide one means of complying with the essential safety requirements of the Directive relating to cableway installations designed to carry persons. During the preparation of this standard, it was assumed that a negotiation would take place betwe
22、en the purchaser and the manufacturer concerning the intended purpose of the rope. Tables of breaking forces are not given in this Part because of the numerous rope constructions and levels of breaking force that are possible from the various combinations of wire shapes and tensile strength grades.
23、1 Scope This Part of this European Standard specifies the particular materials, manufacturing and testing requirements for locked coil carrying ropes for cableway installations designed to carry persons. The particular hazards covered by this Part are identified in Clause 4. 2 Normative references T

EN 12385-9:2002 (E) 5 5 Safety requirements and/or measures 5.1 General In addition to the requirements given in 5.2 to 5.7, the requirements shall also conform to those given in Part 1. The manufacturer shall also comply with prEN 12408. 5.2 Materials 5.2.1 Wire Wires before ropemak
29、ing shall conform to prEN 10264-3. 5.2.2 Lubricant The lubricant(s) shall comply with ISO 4346. NOTEThe properties of the lubricant should take account of any carrying rope brake (see introduction). 5.3 Rope manufacture 5.3.1 Wire joints If joints are necessary, the minimum distance between joints s
30、hall be at least 200 rope diameter (d). The position of any joints shall be documented. 5.3.2 Lubrication Ropes shall be lubricated at each closing operation. 5.3.3 Construction The rope shall have an outer layer of full lock shaped wires. NOTEFor practical manufacturing reasons the actual number of
31、 wires in the outer layer may vary but should not do so by more than one wire from that specified by the manufacturer. 5.3.4Waviness Ropes shall be measured for waviness in accordance with the method specified in annex A. The amount of waviness over a length equivalent to three rope lay lengths shal
32、l not be more than 0,005 d + 0,15 mm. 5.4 Diameter 5.4.1 Tolerances When measured in accordance with 6.6 the diameter shall be within 2 % of the nominal diameter with the rope under load on the closing machine. 5.4.2 Differences between diameter measurements The difference between any two of the fou
33、r measurements taken in accordance with 6.6 and expressed as a percentage of nominal diameter shall not exceed 4 %. EN 12385-9:2002 (E) 6 5.5 Breaking force Only the minimum breaking force shall be specified as the breaking force. The specified minimum value for a given rope size, construction and c
34、ombination of wire tensile strength grades shall be determined by the rope manufacturer. Unless stated otherwise by the manufacturer, the spinning loss factor used in the determination of minimum breaking force shall be 0,875. The manufacturer shall carry out a breaking force test in accordance with
35、 Method 1 as described in 6.4.1 of EN 12385-1:2002 on a sample of rope from each production length. 5.6 Length mass The manufacturer shall specify the nominal length mass. When measured in accordance with 6.7 the length mass shall be in accordance with the specified value, subject to a tolerance of
36、4 %. 5.7 Designation and classification Rope designation and classification shall conform to EN 12385-2. 6 Verification of safety requirements and/or measures 1.1 General Verification of safety requirements and/or measures shall be in accordance with that given in clause 6 of EN 12385- 1 and the add
37、itional verification given in 6.2 to 6.7 below. 6.2 Lubricant Compliance with the lubricant requirements shall be through a visual verification of the inspection documents supplied with the lubricant. 6.3 Lubrication Compliance with the lubrication requirements shall be through a visual verification
38、. 6.4 Construction Compliance with the construction requirements shall be through a visual verification. 6.5 Waviness The method of test for determination of waviness shall be in accordance with annex A. 6.6 Diameter The diameter shall be measured in accordance with 6.3.1 of EN 12385-1 except that t
39、he rope shall be under load on the closing machine. EN 12385-9:2002 (E) 7 6.7 Length mass The measured length mass shall be determined by one of the following methods: a)the gross mass of rope, reel and ancillary items shall be measured. The mass of reel and ancillary items shall be subtracted from
40、this value to give the rope mass. The rope mass shall be divided by the measured rope length on the closing machine; or, b)a sample of rope shall be weighed and the value of the mass shall be divided by the measured length of the rope sample; or c)by calculation. 7 Information for use In addition to
41、 conforming to clause 7 of Part 1, the Certificate (see 7.2.2 of Part 1) shall also state the measured diameter and the measured breaking force. The Certificate shall also state the position of any wire joints in the outer layer. NOTEIf the results of any post-spin testing (e.g. in respect of diamet
42、er, tensile strength, reverse bend, torsion or zinc coating) are required to be given, these can be included on the certificate. EN 12385-9:2002 (E) 8 Annex A (normative) Method of test for determination of waviness Tools required: Straight edge with a straightness of 0,05 mm and a length extending
43、over at least three rope lay lengths. Feeler type gauge (or other equivalent instrument) having increments of at least 0,05 mm and an accuracy of 0,01 mm. Method: At the starting and finishing end of the rope in the closing machine, set the straight edge against the tensioned rope in such a way that
44、 the rope weight will have no influence on the results. Without pressure on the straight edge, determine where the edge makes contact with the rope and secure the edge to the rope at two or more of these positions without affecting the straightness of the straight edge. With a feeler type gauge meas
45、ure the clearance (gap) between each strand and the straight edge over 3 rope lay lengths and record the results. Determination of waviness value: The rope waviness shall be the maximum recorded value of the clearance (gaps). EN 12385-9:2002 (E) 9 Annex B (informative) Information which should be pr
46、ovided with an enquiry or order At least the following information should be provided with an enquiry or order: a) Reference to this standard, i.e. EN 12385-9; b) Quantity and length; c) Nominal diameter; d) Rope construction; e) Wire finish, NOTE The finish of the wires is normally bright unless sp
47、ecified otherwise by the purchaser; f) Lay direction; g) Any particular lubrication requirements; h) Any particular marking requirements; i) Any particular packaging requirements; j) Minimum breaking force required; k) Nominal length mass and whether it is required to be measured or calculated.
