Overview

ISO 22369-1:2006, titled Crop Protection Equipment – Drift Classification of Spraying Equipment – Part 1: Classes, is an internationally recognized standard developed by ISO Technical Committee ISO/TC 23. It establishes a uniform framework for classifying agricultural spraying equipment based on their spray drift reduction performance. Spray drift refers to the unintentional movement of pesticide sprays away from target crops, which can contaminate nearby sensitive areas such as water bodies or non-target vegetation.

This standard applies broadly to spraying equipment used in diverse agricultural contexts, including arable field crops, bush and tree crops, horticulture, and forestry. It aims to provide a consistent basis for rating spray technologies and guiding users to select low-drift equipment, minimizing environmental impact and enabling optimized buffer zones.

Key Topics

• Drift Reduction Definition: Spray drift reduction is quantified by comparing the spray drift deposition of the candidate spraying equipment against a standardized reference spray system under identical test conditions.

• Classification System: The standard defines six classes (A to F) that correspond to specific ranges of drift reduction performance, measured as a percentage decrease in drift relative to the reference:

  • Class A: 95% to 99% drift reduction
  • Class B: 90% to 95%
  • Class C: 75% to 90%
  • Class D: 50% to 75%
  • Class E: 25% to 50%
  • Class F: Less than 25%

• Applicability: The classification system is relevant for various spraying equipment types and parts, allowing evaluation across different agricultural practices and environments.

• Test Protocols: While Part 1 focuses on drift classes, additional parts of ISO 22369 (e.g., forthcoming wind tunnel testing protocols) provide detailed test methodologies to determine equipment drift reduction.

• Environmental Protection Focus: By promoting selection of low-drift equipment, the standard supports reducing spray contamination of watercourses and sensitive ecosystems.

Applications

• Farmers and Agronomists: Facilitates informed decision-making when selecting spraying equipment to minimize off-target pesticide drift, optimizing crop protection while protecting the environment.

• Regulatory Authorities: Provides a framework for setting guidelines, legislation, or best practice recommendations related to pesticide application and environmental safety.

• Equipment Manufacturers: Enables design and marketing of spraying equipment with validated drift reduction performance classes, fostering innovation in precision agriculture technologies.

• Environmental Auditing: Supports environmental impact assessments by quantifying potential drift emissions from various spraying systems.

• Agricultural Extension Services: Assists in training and advising agricultural communities on responsible pesticide application practices.

Related Standards

• ISO 22369-2 (Planned): Focuses on wind tunnel testing methods for spray drift measurements, complementing the classification framework set out in Part 1.

• ISO/IEC Directives, Part 2: Governs the drafting and publication procedures for ISO standards, ensuring consistency and quality.

• ISO/TC 23 Standards on Agricultural Machinery: Other related ISO standards cover tractors, machinery for forestry, and equipment for crop protection, contributing to integrated sustainable agriculture practices.

Summary

ISO 22369-1:2006 is a critical international standard defining the classification of spraying equipment based on their ability to reduce pesticide spray drift. By applying these drift reduction classes, stakeholders across agriculture-ranging from equipment manufacturers to farmers and regulators-can effectively manage spray drift risks, enhance environmental protection, and support sustainable crop production. The standardized drift classes promote transparency, facilitate regulatory compliance, and encourage the adoption of innovative, low-drift spraying technologies worldwide.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
