13、rganization 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 technical committees. Each member body interested in a subject for which a technical committee has been estab
14、lished 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 with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat
15、ion. 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 International Standards adopted by the technical committees are circulated to the member bodies for voting
16、. 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 be the subject of patent rights. ISO shall not be held responsible for identifying any or all such p
17、atent rights. ISO 8224-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 18, Irrigation and drainage equipment and systems. This second edition cancels and replaces the first edition (ISO 8224-1:1985), which has been technically rev
18、ised. ISO 8224 consists of the following parts, under the general title Traveller irrigation machines: Part 1: Operational characteristics and laboratory and field test methods Part 2: Softwall hose and couplings Test methods This corrected version of ISO 8824-1:2003 incorporates the following corre
19、ctions. The French title has been corrected. A redundant reference to the three travelling rate settings has been deleted from 6.2.2 b). Cross-references have been corrected. A typographical error in the title of Figure 6 has been corrected. The y-axis legend fo Figure 7 d) has been corrected to ind
20、icate travel speed. The arrows indicating pressure and flow rate in Figure 7 e) now correspond to the appropriate longitudinal variations shown on the graph. The reference to the role of the third pressure gauge in 8.2.4 has been clarified. In 8.4.3.1 d), the explanation of the ratio has been given
21、its true sense. The same has been done in respect of the different ratio mentioned in 8.4.3.2.

23、nd field test methods for, traveller irrigation machines. It includes user-oriented technical information for inclusion in the manufacturers accompanying product literature, laboratory test procedures for evaluating the uniformity of water application on an irrigated strip by a machine operating wit
24、hin a specified range of conditions and for determining the maximum travelling rates the drive mechanism is able to achieve in response to specified operating conditions, and field test procedures for determining the uniformity of water application on a given irrigated strip under local conditions p
25、revailing in the field at time of testing. It is applicable only to traveller irrigation machines and not to other types of irrigation machine such as centre- pivot and moving lateral irrigation machines. 2 Normative references The following referenced documents are indispensable for the application
26、 of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、hree types of traveller irrigation machine, each having a structure that includes a reel, spool or winch and a travelling water distribution system. Type 1 traveller irrigation machines feature a stationary reel with a hydraulic motor that coils and drags a distribution tube and a travelling cart th

Type 2 traveller irrigation machines feature a travelling winch with a hydraulic motor that supports a water distribution system, coils a tow cable and drags a distribution hose commonly referred to as “travel
33、lers” (see 3.3). Type 3 traveller irrigation machines feature a travelling reel that supports a water distribution system with self- propelled wheels and coiling a stationary distribution tube commonly referred to as “self-propelled reel machines” (see 3.4) or they can be engine-driven machines. 3.2
