Описание (английский):

Cancels and replaces the first edition (1981). Specifies a test method to determine, on the one hand, the effect of fitting antidrip devices on nozzle flowrates, and, on the other hand, the opening and closing pressures. Applies to antidrip devices of agricultural sprayer nozzles, except for hand-held or hand-operated sprayers.

Abstract

Overview

ISO 6686:1995 is an international standard developed by the International Organization for Standardization (ISO) that specifies test methods for evaluating antidrip devices used in crop protection sprayer nozzles. This second edition replaces the original 1981 version, providing a revised technical approach to assessing how antidrip devices affect nozzle flowrates and measuring their opening and closing pressures. The standard applies to agricultural sprayer nozzles except those that are hand-held or manually operated.

Key Topics

Test Methodology: ISO 6686 defines procedures for measuring the impact of antidrip devices on nozzle performance, focusing on flowrate variations with and without devices fitted.
Opening and Closing Pressures: The standard prescribes how to determine the pressure at which antidrip devices open and close, vital for ensuring proper function during spraying operations.
Sampling and Equipment: It outlines requirements for selecting representative samples of antidrip devices and specifies the necessary measurement instruments such as precision manometers, graduated cylinders, and chronometers.
Test Conditions: Tests are conducted under controlled temperature (10-25°C) with pure water, ensuring accuracy within defined pressure stability (+/- 2.5%) and flowrate measurement error (
