13、rds bodies (ISO member bodies). The work of preparing International Standards is normally carried out 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 organ
14、izations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given i
15、n the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International 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 %
16、 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements 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 17899 was prepared by Technical Committee ISO/TC 8, Ships a
17、nd marine technology, Subcommittee SC 5, Ships bridge layout. BSISO17899:2004 vIntroduction A good standard of wiping needs to be ensured for ships safety but there is currently no performance standard for heavy-duty marine electric window wipers. ISO 8468 calls for heavy-duty wipers to be fitted an
18、d applies to all sea-going ships where bridge duty is regularly maintained. This International Standard specifies the requirements for heavy-duty wipers and goes beyond the guidelines in 4.2.3 of ISO 8468 which are confined to the need for an interval function, fresh water wash, capability to operat
19、e independently, and a clear view in all operating conditions. This International Standard includes criteria for wiper operating speeds, durability, ruggedness and environmental compatibility for the complete wiper system. i.e. control system, motors, mechanisms and the wiper blade itself. ISO 3904
20、has been used as a guideline for this International Standard. Equipment meeting these requirements is currently available commercially. This International Standard provides important benchmarks against which independent classification societies can certify. This International Standard embraces all t
21、he common wiper types used, i.e. straight line, pendulum and pantograph, and includes wiper systems with drive motors mounted either inside or outside the ships bridge. BSISO17899:2004blank 1Ships and marine technology Marine electric window wipers 1 Scope This International Standard specifies requi
22、rements for marine electric window wipers. It covers the required features, performance, constructional materials and electrical equipment for wiper systems for sea-going vessels where bridge duty is regularly maintained. It covers the performance, materials and electrical equipment for wipers requi
23、red to meet the needs of ISO 8468 where such wipers are specified. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、 systems General requirements Methods of testing and required test results 3 Terms and definitions For the purposes of this document, the following terms and definitions apply 3.1 wiper unit comprising a drive motor and mechanism, arms and wiping blades 3.2 wiper system system comprising the wiper a
27、nd its control system 4 Requirement The purpose of a heavy-duty electric window wiper is to ensure clear vision in any weather and sea condition, with the ship operating up to its maximum speed in all climatic conditions. BSISO17899:20042 5 Wiped area This should be maximized by the choice of wiper
28、type, size and specification, see Clause 19. 6 Design and construction Wipers shall include types with drive motors mounted inside the bridge and with drive motors mounted outside the bridge. Clause 19 gives designations for each type. Figure 1 shows a typical arrangement for each type. For an expla
29、nation of key dimensions, refer to Clause 19. Figure 1 Typical wiper drive arrangements 7 Speeds The wiper system shall be capable of wiping the central part of its stroke at a rate of at least 50 wipe cycles per minute, i.e. 100 actual wipes per minute. In the case of straight-line wipers, the line
30、ar speed of the blade shall not be less than 68 m/min. BSISO17899:2004 38 Wipe quality Wiper blades should clear the windscreen without leaving streaks and should not damage the glass. Sufficient pressure should be applied to the wiper blade to ensure that, even in severe weather conditions and/or h
31、igh ship speeds, the blade is kept in contact with the screen over its length and over the whole area of wipe. 9 Materials With the exception of those parts of the wiper system mounted inside the bridge, the metallic parts shall be of corrosion-resistant materials as follows: high strength aluminium
32、 alloy with good corrosion resistance according to at least the standard of ISO 6361, ISO 6362 and ISO 6363; corrosion-resistant steel according to ISO/TR 15510, Cr Ni Mo composition. Alternatively, high quality ozone and ultraviolet-resistant structural plastics may be used. Anti-corrosion material
33、 coatings which crack, chip or scale with age shall not be used. 10 Electrical equipment 10.1 Low voltage safety The safety of low voltage electrical equipment shall be in accordance with IEC 60945:2002, 4.6. 10.2 Electromagnetic compatibility Electromagnetic compatibility shall be in accordance wit
34、h IEC 60945:2002, 4.5.1. 11 Provision for de-icing 11.1 General For vessels designed to operate in low temperatures, de-icing equipment shall be fitted which shall allow operation at 25 C with chill factors. Both the mechanisms of the wiper and the arms and blades need to be kept ice-free. For safet
35、y reasons, if electrical power is used for the heating of removable components, like the arms and blades, then a maximum of 24 V should be used. 11.2 Straight-line wipers The heater output shall be fitted to the main casing which maintains operation of the wiper even in the ships lowest specified op
36、erational temperatures and with high wind chill factors. 11.3 Pendulum and pantograph For pendulum and pantograph wipers, heaters shall be fitted either in the arms or in the driving shafts of the arms or in the casings surrounding the driving shafts and these should maintain operation of the wiper
37、even in the ships lowest specified operational temperatures and with high wind-chill factors. BSISO17899:20044 12 Durability 12.1 As a measure of the durability of the complete system, the wiper system shall remain operational after an accelerated life test. This test shall comprise 3 000 h continuo
38、us operation on a dry window and with no water on the mechanism. Damage to a standard wiper blade within that timescale is highly likely, so the blade can be replaced for this test by a heavy-duty blade or a frictional pad with the same frictional properties as the blade and mounted on the arm of th
39、e wiper in the normal way. 12.2 As a measure of the durability of the wiper blade in conditions of inadvertent use on windows that are or have become dry, there shall be no degradation of wiping quality from running the wiper system on a dry window for 10 periods of 1 h in a total test period of 100
40、 h. During the rest of the test, the window should be wet in a normal simulation of rain/seawater spray. 12.3 The wiper system shall endure so as not to require maintenance nor replacement of any component in one year containing a minimum of 3 000 h total of normal (i.e. wet window) operation. The m
41、aintenance period for the system must be not less than 1 year and shall be stated. 13 Salt mist test The parts of the system mounted outside the bridge, shall meet the requirements of the salt mist test defined in IEC 60945:2002, 8.12. 14 Temperature tests The system shall be capable of running cont
42、inuously for 24 h, otherwise as in IEC 60945: 2002, 8.2, 8.3 and 8.4. 15 Salt water test Any electrical parts of the system shall be sealed against sea water ingress. The system shall be capable of running continuously for 3 000 h at normal ambient temperature whilst the system is exposed to salt wa
43、ter. The IP ratings, in accordance with IEC 60529, shall be as follows: The sealing shall be watertight and airtight to IP 67. Control systems should be sealed to a minimum of IP 30. 16 Resistance to mechanical shock The system shall be capable of withstanding the following shocks without failure: 1
44、0 shocks in both directions on 3 mutually perpendicular axes to a level of 10 g (11 ms 1/2 sine wave) i.e. 60 shocks in total. 17 Vibration The system shall be tested in accordance with IEC 60945:2002, 8.7. 18 Compass safe distance Motors shall be tested in accordance with IEC 60945:2002, 11.2, and
45、the certified distances stated. BSISO17899:2004 519 Designation Wiper systems shall be designated as follows: Type specification is: TT - L - SSS(S) - AAAA- BBBB - VVV - TTN-FF Where TT Type SL = Straight line; PH = Pantograpgh; PM = Pendulum.
