Under normal circumstances, the width of the buffer zone or other rules should be determined by considering the type of plant protection machinery that sprays the pesticide and its spray drift. Shift or potential spray drift. The purpose of this document is to determine a test procedure for evaluating the potential spray drift of horizontal boom sprayers through a special test bench, so that Make a quick and easy evaluation of the spray equipment. This test procedure can be used as a field measurement of spray drift (GB/T 24681) or a laboratory measurement of spray nozzle spray drift (GB/T 32241) An alternative method to obtain the spray drift assessment value. The application of this document can provide consulting services for farmers, sprayer manufacturers, product development and certification and classification schemes. Plant protection machinery horizontal boom sprayer Potential spray drift test bench measurement method1 ScopeThis document specifies a measurement method for measuring spray deposits on horizontal boom sprayers using a test bench. Deposit measurement as potential spray Drift provides a value. These measurements can be used to compare different settings of the same sprayer. This document applies to suspended, towed and self-propelled horizontal sprayers for field crops, orchard/vineyard weed control and gardens Horizontal boom sprayer used for art crop application. This document applies to booms that use the same spray device. If it is used for the classification of sprayer spray drift, this document is limited to nozzles Comparison of type, spray pressure and boom height. Note. Further investigations and tests are underway, considering other parameters used to classify the target (e.g. airflow assist system, forward speed, nozzle spacing, and direction).2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document. ISO 5681 Plant Protection Machinery Vocabulary (Equipmentforcropprotection-Vocabulary)3 Terms and definitionsThe following terms and definitions defined in ISO 5681 apply to this document. 3.1 Sprayersetup The combination of nozzle and boom parameters on a given sprayer and sprayer adjustment. Note. For example, when setting parameters, the nozzle type and model, nozzle spacing, orientation, nozzle height, forward speed, spray pressure and spray deposition auxiliary measures should be considered (Such as adding airflow assistance or occlusion). 3.2 Potential spray drift The percentage of the initial spray volume that is still suspended in the air after the sprayer passes, that is, during the spraying process, it is easy to drift out due to the action of the airflow The proportion of spray liquid in the application area. 3.3 Reference spray deposition value referencespraydeposit; RSD Assuming that the spray under the boom is uniformly distributed, the expected spray deposition in the spraying area is calculated based on the measured forward speed and the spray head flow rate. The amount of product. Note. For example, if the application rate is 100L/hm2, the corresponding reference spray deposition value is 1μL/cm2. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 40346-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 40346-2021_English as soon as possible, and keep you informed of the progress.
