It is one Part of a combined revision of BS3
9、02:1968, BS236:1968, BS329:1968, BS330:1968, BS365:1968 and BS3530:1968, which are withdrawn. BS302 is now published in six Parts and takes account of both national and international developments since1968. This Part (Part5) specifies requirements for ropes for hauling purposes additional to the gen
10、eral requirements in Part1. Other Parts specify the additional requirements for other particular uses of ropes: Part 2: Specification for ropes for general purposes; Part 3: Specification for zinc coated ropes for ships; Part 4: Specification for ropes for lifts; Part 6: Specification for ropes for
11、mine hoisting. Two further Parts are in preparation, covering larger diameter ropes(64mm to205mm diameter) and higher strength ropes and will be Parts7 and8 respectively. In line with the principles of International Standard ISO2408, published by the International Organization for Standardization (I
12、SO), the constructions are grouped according to the number of outer wires in the strands. The general requirements of BS302-1 and the methods used for calculating breaking loads and approximate masses comply with ISO2408. In respect of individual usages the ropes in Parts2 and3 are fully in accordan
13、ce with ISO2408 and those in section 2 of Part4 are in accordance with ISO4344. In each of these Parts however, certain additional ropes still in common use in the UK have been included. In line with current international practice, the term “zinc coated” has been adopted in this standard in place of
14、 “galvanized”. The terms are synonymous. Purchasers ordering to BS302 are advised to specify in their purchasing contract that the manufacturer operate a quality system in compliance with the appropriate Part of BS5750, or suitable equivalent, to ensure themselves that products claimed to comply wit
15、h BS302 consistently achieve the required level of quality. Wire rope users will find valuable information in the companion publication BS6570 “Code of practice for the selection, care and maintenance of steel wire ropes”. A British Standard does not purport to include all the necessary provisions o
16、f a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 6, an inside
17、back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS302-5:1987 BSI 03-2000 1 1 Scope This Part of BS302 specifies the requirements for round and triangular
18、 strand steel wire ropes for hauling purposes and is for use in conjunction with BS302-1. NOTE 1Information to be supplied by the purchaser on the enquiry and order is given in AppendixF of BS302-1:1987. NOTE 2The titles of the publications referred to in this standard are listed on the inside back
19、cover. 2 Definitions For the purposes of this Part of BS302, the definitions given in BS302-1 apply. 3 Compliance Ropes in accordance with BS302-5 shall comply with this Part and with BS302-1. 4 Wire rope constructions and sizes Constructions and size ranges shall be as given in Table 1. NOTEIn the
20、absence of a precise indication by the purchaser on the enquiry and order, the choice of construction within a group is at the discretion of the supplier. 5 Material 5.1 Wire 5.1.1 General. The wire used for the manufacture of wire ropes in accordance with BS302-5, excluding the wire used in the cor
21、es of triangular strands, shall comply with BS2763 as follows. a) For man-riding haulage installations: sections1 and3. b) For other purposes: sections1 and2. For these ropes the reverse bend test clause in BS2763 shall be applied. 5.1.2 Wire finish. The wire shall be Class Z zinc coated or bright.
22、The zinc coating shall comply with BS2763. 5.1.3 Tensile grades of wire. All wires except king wires, wires comprising the triangular strand core, and wires of the steel main core shall be of1570N/mm 2 1)or1770N/mm 2tensile grade. For round strand ropes the king wires shall all be of one tensile gra
23、de selected from BS2763. For triangular strand ropes the strand core wires shall have a minimum tensile strength of770N/mm 2in cores comprised of solid triangular wires or three round wires, and a minimum tensile strength of1270N/mm 2in cores built up from more than three round wires. NOTEIn order t
24、o achieve a required triangular shape some low carbon steel wires may be added. 5.2 Rope main core 5.2.1 General. The main core of the rope shall be of fibre or steel. 5.2.2 Fibre core. Fibre cores shall comply with3.2 of BS302-1:1987. 5.2.3 Steel core. Where a steel core is used, it shall be an ind
25、ependent wire rope (IWRC) for rope sizes of13mm diameter and above. For sizes smaller than13mm diameter the steel core shall be either an IWRC or a wire strand (WSC). All wires forming a steel main core, except king wires, shall be one tensile grade. 6 Direction of lay Ropes shall be of right-hand o
26、r left-hand Langs lay. NOTE 1It will need to be stated by the purchaser on his enquiry and order if left-hand lay is required, otherwise right-hand lay will be supplied. NOTE 2In the case of haulage ropes in which a long splice is to be made, the aspects of lay length and preforming require to be ta
27、ken into consideration. The lay length is at the discretion of the manufacturer, but there may be cases when the purchaser will require to nominate the lay length specifically for long splicing purposes. 7 Lubrication All cores except those of man-made fibre shall be suitably treated. The rope shall
28、 be fully lubricated during stranding and closing. All lubricants shall comply with3.3 of BS302-1:1987. NOTEThe degree and type of lubrication should be agreed between the purchaser and the supplier. 8 Minimum breaking load The minimum breaking loads shall be as given inTable 2 toTable 5. NOTEFor gu
29、idance, these tables also give approximate masses of ropes, calculated as inC.2 of BS302-1:1987. 1) 1 N/mm 2= 1 MPa.BS302-5:1987 2 BSI 03-2000 Table 1 Wire rope constructions and sizes Rope group Description Size range (diameter) Typical construction mm 6 7 Up to7 outer wires in a strand, one layer
