14、aphy14 BS ISO 9533:2010 ISO 9533:2010(E) iv ISO 2010 All rights reservedForeword 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 out through ISO tech
15、nical 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 collaborates closely
16、 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 Standards. Draft I
17、nternational 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 elements of this document
18、 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9533 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety, ergonomics and general requirements. This second edition cancels and repl
19、aces the first edition (ISO 9533:1989), which has been technically revised. Notably, test methods and criteria have been modified to include the evaluation of self-adjusting sound level alarms and travel warning alarms.

20、erved 1Earth-moving machinery Machine-mounted audible travel alarms and forward horns Test methods and performance criteria 1 Scope This International Standard specifies a static method for determining the sound output performance and alarm activation requirements of audible travel alarms and forwar
21、d horns mounted on earth-moving machinery, as defined in ISO 6165, for operation on work sites and travelling on public roads. It offers objective test methodologies and performance criteria. It is applicable only to those alarms and horns that are installed on the earth-moving machinery. It does no
22、t specify the installation of one or more audible travel alarms or forward horns on particular machines. It addresses neither the laboratory testing of warning alarm functionality nor durability. NOTE Earth-moving machine manufacturers practices, worksite requirements and local, national or regional
23、 regulations could require the fitting of the alarms or horns specified in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the
24、latest edition of the referenced document (including any amendments) applies.

30、level independent of ambient sound levels 3.5 self-adjusting sound level alarm audible travel alarm that automatically adjusts its sound level, throughout a defined range, in order to maintain a sound level differential between the output of the alarm and the ambient sound level measured by the alar

32、ound level meter with an extension cable or equivalent sound measurement system that meets the performance requirements of IEC 61672-1, Type 1. It is recommended that for the purposes of this International Standard all sound pressure level measurements be rounded to the nearest whole number in decib
33、els. 4.2 Acoustical calibrator, or equivalent measurement system, recommended to be used each day of measurement to calibrate the sound level meter prior to testing and for checking sensitivity drift after test completion. The effects of atmospheric pressure, temperature and use of a windscreen shou
34、ld be accounted for within the system calibration as recommended by the manufacturer of the instrumentation. 4.3 Microphone wind screen, designed for sound measurement and recommended by the manufacturer of the sound level meter or equivalent sound measuring system, which shall be used to maintain c
35、onsistency from test to test and add protection to the microphone assembly. 4.4 Anemometer, or other device, for measuring ambient wind speed and direction, accurate to within 10 % at the highest recommended wind speed.

36、ional frequency indicator with an accuracy to within 2 % of the indicated engine rotational frequency. 4.6 Thermometer for measurement of ambient temperature accurate to within 2 C. NOTE Apparatus will also be needed for checking the test environment (see 5.1). 5 Test environment 5.1 Test area The t
37、est area shall consist of a free field above a hard reflecting plane no rougher than non-porous asphalt. The test area bordered by the machine and the microphone shall also consist of a flat, horizontal surface or surface sloping downwards away from the centre of the test area. No reflective objects
38、 such as buildings should be within 30 m of the microphone or the machine being measured. The test technician or test equipment shall be 2 m from the sound-measuring microphone during exterior location measurements. NOTE For further details giving the recommended test area configuration, see ISO 374

NOTE For further details giving recommended climatic conditions, see ISO 6393. 5.4 Wind The average wind speed at the test site shal
41、l be less than 8 m/s. Wind speeds at each measurement location due to machine operation should also be below 8 m/s. For measurement locations where wind speeds are above this value, sound measuring equipment designed for high wind applications should be used. 6 Machine preparation 6.1 Voltage Verify
42、 that the alarm activation voltage to the audible travel alarm(s) or forward horn is within the nominal operating voltage specified by the manufacturer of the travel warning alarm(s) or forward horn. 6.2 Engine and transmission 6.2.1 General Under prevailing conditions, the machine shall be at a sta
43、bilized temperature for all its primary power systems at maximum governor engine speed (high idle). BS ISO 9533:2010 ISO 9533:2010(E) 4 ISO 2010 All rights reserved6.2.2 Cooling system fan speed(s) If the powertrain or hydraulic system or systems of the machine are fitted with an adjustable fan or f
44、ans, they shall operate during the test at maximum achievable fan speed at the engine speed as specified in Clause 7. If equipped with an electric fan or fans, these shall be off when taking sound pressure measurements with the engine off. 6.3 Equipment and attachments For testing, the equipment and
45、 attachment(s) for the most typical machine configuration as specified by the machine manufacturer shall be installed and in the carry position for travelling (see ISO 5006). The attachment position shall also be as specified by the manufacturer. 6.4 Operator station 6.4.1 Heating, ventilation and a
46、ir-conditioning system If the operator station is equipped with a heating, ventilation and air-conditioning (HVAC) system or systems, these shall be set to mid-setting during all tests, defined below. The ventilation ducts shall be open with the air flow directed out but away from the operator. For
47、an Off/Low/High system, at mid-setting the HVAC fan setting(s) will be at “High”. For an Off/Position 1/Position 2/Position 3 system, the mid-setting will be Position 2. For a continuously variable system, the mid-setting is at or above 50 % of the maximum fan speed. If the HVAC system consists of m
48、ultiple systems, e.g. separate upper and lower controls, all systems shall be set to mid-setting. NOTE For further details on fan speed and fan settings, see ISO 6393. 6.4.2 Operator size and location For testing at the location of the operator, an operator should be selected whose physical dimensio
49、ns are as close as possible to a medium operator, and within the limits for a small to a large operator, as defined in ISO 3411. The seat shall be positioned in the mid-position for fore and aft and for vertical height, if adjustment is provided. The seat and head rest, if present, shall be adjusted to accommodate the operator and shall remain consistent during the test series. 6.4.3 Additional considerations Other considerations for the operator station include eliminating non-typical machine noise such
