多孔的噴頭用此分級無法直接應用在瞭解
噴頭的霧滴大小，但是其流量可作為施藥
時評估精準施藥應計算的行走速率參考，
用已知的流量作為計算行走速率及施藥的
基準，亦是將噴頭進行規格訂定及區分的
優點。
六、霧滴飄散試驗建立及測試
利用建立的控制環境測試不同粒徑大
小霧滴可能之飄散距離，測試不同風速
下，噴頭於固定風速風向條件下之飄散距
離。以水試紙

Based on ISO standard 10625 “Equipment for crop protection -- sprayer nozzles -- colour coding for
identification” (with a relative tolerance of
±
5% L/min).
2)
“None:” None of the 9 nozzles investigated in this study can be classified at this size code.
3)
Data only represents flow rate comparison, not size code classification. Note that ISO standard 10625 is not
applicable to nozzles where more than one component influences flow rate.
