Overview

ISO 5682-3:2017 is an international standard developed by the International Organization for Standardization (ISO), focusing on equipment for crop protection, specifically the spraying equipment used in agriculture. This standard defines the test method to assess the performance of volume/area adjustment systems in spray systems, essential for ensuring accurate application of pesticides or fertilizers over crops.

This standard applies broadly to automated or mechanically controlled spraying systems but excludes manually-operated knapsack sprayers and aircraft sprayers. By providing a reliable test method, ISO 5682-3:2017 helps manufacturers, testing laboratories, and end-users evaluate and verify the precision of spray volume regulation to promote efficient and safe crop protection practices.

Key Topics

• Scope and Applicability
  ISO 5682-3:2017 focuses on testing the regulation of spray volume per hectare, which is pivotal for uniform crop treatment. The scope excludes manual and aerial spraying equipment.

• Testing Conditions
  The standard outlines detailed testing conditions:

  • Use of water as the test liquid at the spray boom level
  • Simulation of forward speed and pump frequency when the sprayer is stationary
  • Specific nominal forward speeds (e.g., 4, 6, 8, 16, 24 km/h) and pump rotations depending on equipment type
  • Measurement and data recording protocols for stable system operation

• Test Procedures
  ISO 5682-3:2017 sets test steps including:

  • Opening and closing boom sections to evaluate system responsiveness
  • Varying speeds and pump frequencies to assess system adaptation
  • Multiple repetitions to ensure data reliability
  • Calculation of volume per hectare variation and deviation from nominal setpoints

• Performance Metrics
  Performance evaluation is based on:

  • Coefficient of variation (expressed as a percentage) of volume applied per hectare
  • Maximum positive and negative deviations from mean volume
  • Time periods when spray volume deviates beyond ±10% from stable reference values

• Reporting
  A structured test report format is recommended, including detailed logs of timing, volume measures, and calculated performance parameters for transparency and traceability.

Applications

ISO 5682-3:2017 serves practical functions in various aspects of agricultural spraying technology:

• Sprayer Manufacturers
  Use the standard to validate and optimize volume/area adjustment systems during design and production stages, ensuring compliance with industry expectations for precision.

• Agricultural Equipment Testing Laboratories
  Implement ISO 5682-3:2017 methods to objectively assess sprayer performance against standardized criteria, delivering trusted certification and quality assurance.

• Farm Operators and Agronomists
  Ensure that spraying equipment delivers accurate volumes per hectare under different operating conditions, maximizing crop protection efficacy while minimizing chemical waste and environmental impact.

• Regulatory Bodies and Extension Services
  Utilize the standard as a benchmark for equipment performance compliance to meet local agricultural regulations and support best practices in crop spraying.

Related Standards

ISO 5682-3:2017 is part of the broader ISO 5682 series related to crop protection spraying equipment. Users should consider these complementary standards for a comprehensive understanding of sprayer technology:

• ISO 5682-1:2017 - Test methods for spray nozzles, focusing on spray pattern and flow rate characterization.

• ISO 5682-2:2017 - Methods to evaluate the horizontal transversal distribution of sprayed liquid, crucial for assessing boom coverage uniformity.

• ISO 5681 - Provides vocabulary and definitions pertinent to plant protection products and spraying equipment, ensuring consistent terminology.

Together, these standards support the design, testing, and operation of crop protection equipment to promote uniform application, efficiency, and environmental safety.

---

By adhering to ISO 5682-3:2017, agricultural stakeholders can confidently verify the performance of spraying volume regulation systems, helping achieve optimal pest and disease control in modern crop production. This contributes to sustainable agriculture through precise, controlled use of protection chemicals.
