The work of preparing International Standards is normally carried out through ISO technica
8、l 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 wit
9、h 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 Inter
10、national 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 may

ISO 6394 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety requirements and human factors, in collaboration with Technical Committee ISO/
12、TC 43, Acoustics, Subcommittee SC 1, Noise. This third edition cancels and replaces the second edition (ISO 6394:1998), which has been technically revised. -,-,- ISO 6394:2008(E) iv ISO 2008 All rights reserved Introduction This International Standard is a specific test code for earth-moving machine
13、ry as defined in ISO 6165. It is an extension of ISO 11201, which contains the general requirements of many types of machinery and equipment. Specific procedures are described in this International Standard to enable the time-averaged A-weighted emission sound pressure level in stationary test condi
14、tions to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturers production version are intended to be fitted since this is the configuration most likely to exist when the machine is in actual use. This International Standard enables compliance with noi
15、se limits to be determined, if applicable. It can also be used for evaluation purposes in noise reduction investigations. A complementary test code is given in ISO 6393. This other specific test code is intended to be used to determine the noise emitted by earth-moving machinery in terms of the A-we
16、ighted sound power level with the machine under stationary test conditions. Corresponding measurements of noise emitted to the environment and noise at the operators position under dynamic test conditions are described in ISO 6395 and ISO 6396, respectively. -,-,- INTERNATIONAL STANDARD ISO 6394:200
