12、nization 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 establis
13、hed 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 standardization
14、. 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. P
15、ublication 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 pate
16、nt rights. ISO 22368-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 6, Equipment for crop protection.

18、) v Introduction The cleaning of sprayers used in crop protection is becoming increasingly important, especially for the following reasons: to avoid contamination of the environment and the operator; because of the possibility of accidental release of agrochemicals that could cause crop damage, rais
19、e residue fears or lead to the mixing of incompatible crop protection products. Moreover, it is likely that the relevant sections of the industry are in need of guidance in developing cleaning systems, so that the state of the art and a basis for future specifications can be evaluated. ISO 22368-1 a
20、nd ISO 22368-2 specify test methods related to the internal and external cleaning of sprayers, offering the user the means to evaluate the general performance of both inside and outside cleaning systems and a possible basis for defining performance specifications in the future. The standard also off
21、ers individual sections for key sprayer components (see ISO 22368-3). This part of ISO 22368 enables the cleaning system to be evaluated for specific components and provides the means for obtaining detailed results that can be used for its improvement.

23、ethods for the evaluation of cleaning systems Part 1: Internal cleaning of complete sprayers WARNING Users of this part of ISO 22368 should be familiar with normal laboratory practice. This part of ISO 22368 does not address all possible safety problems associated with its use. It is the responsibil
24、ity of the user to establish appropriate safety and health practices and ensure compliance with any national regulatory conditions related to safety and environmental issues. 1 Scope This part of ISO 22368 specifies tests for determining the performance of the rinsing systems fitted onto sprayers us
25、ed in crop protection for the internal cleaning of the complete sprayer, including the tank. It is applicable to mounted, trailed and self-propelled agricultural sprayers used for crop protection and liquid fertilizer applications. It is not applicable to sprayers with direct injection systems. 2 Te
26、st conditions Testing shall be performed under the following conditions. Temperature of test liquid: 5 C to 25 C. Air temperature: 5 C to 25 C. Relative humidity of air: 30 %. Where testing is done outdoors, the influence of climatic/weather conditions should be considered. 3 Tests 3.1 General SAFET
27、Y PRECAUTIONS Because of possible environmental hazards inherent in this method, recognized precautions shall be observed to eliminate accidental release of test liquids outside the test site. All operations should preferably be carried out such that the test liquids and the water used to clean the
28、sprayer can be collected. If this is not the case, care shall be taken that the spread liquids do not cause any environmental damage. Testing shall be performed using a 1 % suspension of copper oxychloride test liquid according to Annex A and the present clause. Other traced liquids may be used if t
29、he same level of measuring performance can be demonstrated. For this purpose, accuracy of measurements for example should be at least 0,01 % of the original tank concentration. The test liquid may be used on several occasions providing checks show that there are few, if any, changes to its original
30、specification.

Fill u
31、p the tank completely with test liquid while the agitator or agitators are running. Ensure that all internal surfaces especially the upper ones and the lid are wetted with the test liquid and use all functions, including pressure agitation, induction bowl and the pressure relief valve. Wait for 10 m
32、in while the agitator(s) is running. Take three representative samples from the sprayer tank to check the concentration of the reference test liquid. Each of these samples shall have a volume of at least 50 ml and shall not deviate by more than 5 % from the concentration of the reference liquid. Emp
33、ty the tank as in normal spraying practice (e.g. normal PTO speed, pressure, nozzle size, nozzle number, flow rate) by using the whole spray boom. Wait until there is not any liquid coming out of the nozzles. 3.2.2 Operate the rinsing system of the sprayer according to the manufacturers instructions
34、. Empty the tank as in normal spraying practice by using the whole spray boom. Wait until there is not any liquid coming out of the nozzles. 3.2.3 Fill the sprayer completely with clean water. Ensure all internal surfaces, especially the upper ones and the lid, are cleaned with the water. Use all fu
35、nctions (pressure agitation, induction bowl, pressure relief valve, etc.). 3.2.4 Start spraying and collect the liquid in a separate tank (A). 3.2.5 Take three representative samples out of Tank A. Each of these samples shall have a volume of at least 50 ml and shall not deviate by more than 5 % fro
36、m the mean concentration of the Tank A liquid. 3.2.6 Determine the concentration of the copper of the samples taken according to 3.2.1 and 3.2.5 by using appropriate methods such as atomic-absorption-spectrometry. Calculate the mean values of the samples. 3.2.7 Calculate the fraction, F, of the mean
37、 concentration of the samples taken according to 3.2.1 and 3.2.5 as a percentage using the following equation: AM RM 100 % C F C = 3.2.8 Record the data in the test report (for an example test report, see Annex B). 3.3 Optional test (to show the cleaning process of the rinsing system) procedure Oper
38、ate the rinsing system of the sprayer according to the manufacturers instructions, but divide the rinsing water in two or more parts. Take samples at the end of each cycle under the nozzle with the longest supply hose at the end of each rinsing process (just before the spray jet is collapsing). Calc
39、ulate the concentration of the samples according to the concentration of the reference test liquid.
