14、 10 Annex A (informative) Recommended production tests and inspections 11 BSISO799:2004iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried ou
15、t through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO co
16、llaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International
17、Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the element
18、s of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 799 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. This third edition cancels an
19、d replaces the second edition (ISO 799:1986), of which it constitutes a complete revision in order to take into account new designs and manufacturing methods for pilot ladders which have entered the market since 1986. BSISO799:2004 vIntroduction This International Standard is intended to supplement
20、existing IMO requirements for pilot ladders. Since IMO instruments do not include specific requirements for prototype testing of pilot ladders for approval, the tests included in this standard are in excess of the existing IMO requirements. The inclusion of these tests was considered necessary in or
21、der to provide a means of ensuring conformance of pilot ladders with the performance requirements prescribed in IMO instruments and in this International Standard. BSISO799:2004blankINTENRATIONAL TSANDADR IS:997 O4002(E)1Ships and marine technology Pilot ladders 1 Scope This International Standard s
22、pecifies requirements for a ships pilot ladder which is provided to enable a maritime pilot to embark and disembark a ship safely along a vertical portion of the ships hull. It is applicable to merchant ships which embark and disembark maritime pilots with the ship underway. National maritime safety
23、 administrations are urged to accept ladders complying with this International Standard on their ships, as complying fully with the requirements of the 1974 International Convention for the Safety of Life at Sea (SOLAS), as amended. 2 Normative references The following referenced documents are indis

31、 part shall be 5254 or 5652 alloy, or other grade containing not more than 0,06 % copper, in accordance with ISO 209-1. 3.3.5 Metals in contact with each other shall be galvanically compatible, or insulated to prevent galvanic corrosion in a marine environment. 3.4 Mechanical fastening devices Each
32、mechanical fastening device securing a part of a ladder shall have a locking mechanism to prevent the device from loosening. 3.5 Plastic materials Each plastic material shall be of a type that retains at least 30 % of its original tensile strength and at least 80 % of its original impact strength wh
33、en subjected to the one-year outdoor weathering test described in Method A of ISO 877:1994. 3.6 Quality of materials Each part of a ladder shall be free of splinters, burrs, sharp edges, corners, projections, or other defects that could injure a person using the ladder. 3.7 Rope seizing Seizing, if
34、used, shall consist of two- or three-ply marline of minimum breaking strength 800 N, or other suitable material of equivalent strength. 4 Construction 4.1 Each ladder shall have two side ropes on each side. Each step in the ladder shall be supported by each side rope. 4.2 The side ropes shall a) be
35、continuous from the top of the ladder to the bottom, and b) not be painted or otherwise coated or covered. 1) See Iron & Steel Society (ISS) publication Stainless Steels, available from Iron & Steel Society, 186 Thorn Hill Road, Warrendale, PA 15090-7528, USA, or http:/www.iss.org.

36、3 Unless a special arrangement is needed to secure the ladder to an accommodation ladder, powered pilot hoist, or other custom installation, the ends of the side ropes shall be finished as follows. a) The top end of one or both of the side ropes on each side shall terminate just above the top step i
37、n a single eye splice or thimble large enough to accommodate at least two passes of side rope. b) The top end of one side rope on each side of the ladder shall extend at least 3 m beyond the top ladder step, or an extension service rope shall be fitted to each side rope eye splice or thimble by mean
38、s of an eye splice or shackle, as shown in Figure 1. The diameter of an extension service rope shall be at least the diameter of the side ropes. c) The side ropes shall not have fittings or form loops at the bottom of the ladder that can be used to attach additional ladder sections or tripping lines
39、. d) The ends of each side rope which do not terminate in a splice or fitting, shall be served or otherwise treated to prevent fraying.

40、rvice rope arrangements at top of ladder 4.4 Each side rope shall pass through a hole in each step. If the hole is in the form of a slot, the slot shall be in the longer edges of the steps. The centre of each hole shall be at least 50 mm from the end of the step. Alternative arrangements are shown i

BSISO799:20044 Dimensions in millimetres Key 1 grooved, patterned or textured non-skid surface area Figure 2 Typical ladder step showing alternative hole and slot designs for side ropes 4.5 Each pair of side ropes shall be secured together both above and below each step with a mechanical
42、 clamping device or seizing method which holds each step level when the ladder is hanging freely. Alternative arrangements are shown in Figure 3. 4.6 If a mechanical clamping device is used to secure the side ropes and hold the step in place, the device shall not extend above or below the step surfa
43、ces by more than a distance equal to 0,7 W (where W is the width of the step), so that the step is not prevented from rolling if caught between a boat and the hull of the ship. See Figure 3. 4.7 If a seizing method is used to secure steps and side ropes, a step fixture shall be used above and below
44、the step. The step fixture shall be designed to lead and support the side ropes from the step to the point above or below the step where the side ropes are seized together. The step fixture shall be designed so that it stays in place when the ladder is rolled or the step is turned. 4.8 The clear spa
45、ce between the side ropes on one side of the ladder and those on the other side shall be at least 400 mm. This distance shall be uniform throughout the length of the ladder. See Figure 2. 4.9 Each side rope shall be arranged so that, when the ladder is in use along the vertical hull of a ship, the s
46、ide rope cannot come in contact with the ships side. 4.10 The spacing from the top of one step to the top of the next step shall be 330 20 mm, and shall be uniform throughout the length of the ladder. See Figure 3. 4.11 Each step shall be of one-piece construction, of either wood or resilient plasti

48、op face of each step shall have a rectangular surface that is at least 115 mm wide with a surface that is grooved or patterned, or of a textured non-skid type. The step surface shall be designed so that it does not retain water. A textured non-skid surface shall be moulded into the step or adhered d
49、irectly to it. Non-skid adhesive sheeting may not be used. See Figure 2. 4.13 Each step shall be at least 25 mm thick at its thinnest point. In determining this thickness, the depth of grooves in the top face of the step, the diameter of any hole extending from one side of the step to the other, and the thickness of any non-skid treatment shall not be included. See Figure 2. 4.14 Each step shall be arranged so that it can bear on the vertical hull of the ship
