9、ization 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 establish
10、ed 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.

15、ing reasons: to avoid the contamination of the environment and the operator; the accidental release of agrochemicals that may cause crop damage, raise residue fears or lead to mixing of incompatible crop protection products.In addition, it is likely that the relevant bodies of the industry will need
16、 guidance in developing systems for cleaning the sprayer for emptying the sprayer as far as possible, to enable the evaluation of the state of the art and to establish a basis for future specifications.The main purpose of ISO 16236 is to define the standardized procedure to determine the drainable v
17、olume which can be emptied in the field after carrying out the cleaning procedure as recommended by the sprayer manufacturer. This drainable volume can be relevant when letting out the rinsing liquid (drainable volume) of the tank by using its outlet. Furthermore, other outlets should be included (e
18、.g. suction filter, pressure filter, filling connection). In this sense, this International Standard completes ISO 13440 and ISO 22368-1 to -3. ISO 2013 All rights reserved vBS ISO 16236:2013BS ISO 16236:2013Crop protection equipment Test method for the determination of drainable volume and its conc
19、entration1 ScopeThis International Standard specifies the test method for the determination of the volume and the concentration of the drainable volume of sprayers, in connection to the emptying of the diluted residue of the spray tank by using its outlet and other outlets allowing draining (e.g. su
20、ction filter, filling connection) at the end of the cleaning procedure.It applies to agricultural sprayers used for crop protection and liquid fertiliser applications for both brand new sprayers and sprayers already in use.2 Terms and definitionsFor the purposes of this document, the following terms
21、 and definitions apply.2.1drainable volumeamount of liquid collectable from the spray tank outlet and/or other outlets, intended for emptying the sprayer at the end of the cleaning procedure2.2rinsing systemsystem that is fitted onto sprayers and used for the internal cleaning of the complete spraye
22、r including the tank3 Test conditionsTemperature of the test liquid: 5 C to 30 C.Air temperature: 5 C to 30 C.Relative humidity of air: 30 %.4 Test4.1 Test liquidThe preferred test liquid is water with an approximate concentration of 0,000 1 % of fluorescein sodium (extra pure).Other traced liquids
23、may be used, if the same level of measuring performance can be demonstrated.4.2 Test procedure4.2.1 The test shall be carried out with the sprayer kept in a stationary and horizontal position. The internal surfaces of the complete sprayer shall be carefully cleaned at the start of the test.4.2.2 Fil
24、l up the tank with water to at least 10 % of the nominal tank volume and introduce approximately 1 mg of the tracer per litre of water into the tank through the tank opening with the agitator(s) running. If the sprayer is equipped with an induction hopper, it should not be used in order to avoid its
25、 contamination. INTERNATIONAL STANDARD ISO 16236:2013(E) ISO 2013 All rights reserved 1BS ISO 16236:2013ISO 16236:2013(E)To ensure the same contamination as in normal practice, use and operate all functions needed during the spraying process as specified in the operators manual. Run the agitator(s)
26、for at least 1 min. Open the outlet valve, collect test liquid enough to ensure the contamination of the outlet device and refill it again to the main tank. To contaminate the complete sprayer (hydraulic circuit and internal parts of the main tank), operate all valves as specified by the operators m
27、anual and spray an appropriate amount of test liquid. For sprayers without agitation, contaminate the internal part of the tank by shaking or turn off the equipment several times.4.2.3 Take one representative sample of at least 50 ml, from the sprayer tank to check the concentration of the test liqu
28、id. Enter the concentration in Table A.1.4.2.4 Empty the tank as in normal spraying practice (e.g. normal PTO speed, pressure, nozzle size, nozzle number, flow rate) by using all nozzles (e.g. the whole spray boom). Allow the pump to run for 1 min 5 s after the liquid fan from the nozzles has collap
29、sed to ensure that all relevant liquid has been emptied. For shutting off the pump when completely emptying the tank the specification in the instruction handbook apply, if available.4.2.5 Operate the rinsing system of the sprayer according to the operators manual. If no special rinsing instructions
30、 from operators manual are available carry out a rinsing procedure where the rinsing water is used in three portions. Each portion equals to one third of the volume of the clear water tank or 10 % of the nominal volume of the spray tank divided by three. Measure the volume of each portion of rinsing
31、 water with a maximum error of 2 % of its nominal volume. After each step of this procedure, spray the rinsing liquid as in normal spraying practice.If no rinsing system is available, carry out a rinsing procedure where the rinsing water is used in three portions with a clean water volume correspond
32、ing to at least 10 % of the nominal tank volume of the sprayer. For this purpose, the rinsing water is to be filled in by the filling opening.When each rinsing process is coming to the end, ensure that the agitators are switched off before the pump sucks air in and wait till there is not any liquid
33、coming out of the nozzles, so that the drainable volume is minimized.4.2.6 After the rinsing process, stop the pump drive, operate all relevant valves allowing to discharge the liquid still present in the hydraulic circuit and let the drainable volume out of the tank by using its outlet. Open other
34、outlets allowing draining tool-free (e.g. suction filter, pressure filter, further discharge valves positioned along the hydraulic circuit, filling connection) and make sure to collect all the liquids running out in separate clean containers. Measure the collected volumes individually and record the
35、m in Table A.2.4.2.7 Take one representative sample, of at least 50 ml, out of each container.4.2.8 Conduct the test procedure from 4.2.1 to 4.2.7 at least three times.4.2.9 Determine the concentration of the tracer in the samples taken in 4.2.3 and 4.2.7 by using appropriate methods with a maximum
36、error of 0,01 % of the original tank concentration. Record these concentrations in Table A.3.4.2.10 Calculate the total amount of tracer of the collected drainable volumes (using Table A.4) by multiplying the volumes measured in 4.2.6 (Table A.2) and the concentrations determined in 4.2.9 (Table A.3
37、). Calculate also the total amount of tracer from these measurements.4.2.11 Calculate the mean values and the coefficients of variation Cvof measured volumes and concentrations (using Tables A.2 to A.4). Each Cvshould not exceed 15 %. If one or more Cvvalues are higher than 15 %, repeat the test.4.2
