Introduction

For the following reasons, plant protection sprayer cleaning becomes more and more important.

--- In order to avoid contamination of the environment and the operator;

--- Pesticide that may occur because of an accidental discharge causing crop injury, triggering fears of increased pesticide residues, or Caused by pesticides mixing several mutually exclusive.

In addition, the relevant industrial sector may need to provide development guidelines washing system to assess the level of technological development and future technology base.

GB/T 24684.1 and GB/T 24684.2 provisions of the relevant test methods and internal and external cleaning sprayer, to provide users Evaluation of internal and external cleaning system as well as the overall performance of a method to determine the future technical performance basis. This series of standards for the spray organs Key components provides a separate chapter (see GB/T 24684.3).

This section evaluation of cleaning a particular part of the system provides test methods in detail the results obtained may be improved and perfected cleaning systems Provide evidence. This section seeks to provide one kind of standard test procedures in order to simulate normal operating conditions of the liquid sprayer contamination. root According to the test target, you can use two different test methods for any one or two ways. A test designed to develop or adjust the sprayer will External contamination is minimized by the sprayer; B test to compare different systems used to clean the sprayer, and for the future that might be raised to Required to examine the performance of the cleaning device.

GB/T 24684.2-2009/ISO 22368-2:2004 Plant protection machinery Test methods for the evaluation of cleaning systems Part 2. External cleaning of sprayers WARNING. Users should be familiar with this part of the routine laboratory practice. This section related to the use of all possible security not addressed Wide issues. Users should make their own provisions appropriate safety and health practices and to ensure compliance with relevant national safety and environmental provisions.

1 Scope

This section GB/T 24684 specifies the evaluation of the cleaning system installed on the plant protection sprayer for cleaning the outer surfaces of the sprayer deposition Two test methods for system performance. The trial is designed to provide information on pollution sprayer to sprayer designer, and with an external cleared Wash the press concerning various accessories or adjusting means is compared (test A), and provides a method (Test B) as measured in the cleaning system performance.

This section applies to plant protection and spraying liquid fertilizer suspended, towed and self-propelled agricultural sprayers.

2 Terms and definitions

The following terms and definitions apply to this section.

Mounted on a sprayer for cleaning the outer surface of the part of the sprayer.
