Full title and description

ISO 22866:2005 — Equipment for crop protection — Methods for field measurement of spray drift. This International Standard defines principles and field procedures for measuring droplet drift from equipment used to apply plant protection products (notably tractor-mounted, trailed and self-propelled boom sprayers, and air-assisted sprayers for tree and bush crops).

Abstract

ISO 22866:2005 establishes principles for the measurement of droplet drift from all types of crop‑protection application equipment. It specifies field measurement arrangements, standard measurement distances and measurement/reporting practices so results from different experiments can be compared for risk assessment and classification purposes. The standard's principles are also applicable to hand‑held equipment and aircraft, although detailed protocols for those systems are not included.

Scope

Specifies methods for making field measurements of spray drift during application of plant protection products so that quantities of off‑target drift can be determined at defined distances from a treated area. Detailed specifications focus on boom sprayers for arable crops and sprayers used in tree and bush crops (including broadcast air‑assisted systems). The standard is intended to support risk assessment and comparability between field trials; it does not provide detailed protocols for every spray system type (for example, hand‑held units or aerial application are covered only at the principle level).

Key topics and requirements

• Principles for measuring droplet drift and establishing field test layouts (downwind sampling lines, buffer/transect positions).
• Definition of standard measurement distances from the treated area to enable comparability between trials.
• Requirements for deposition samplers and collectors, sample handling and laboratory analysis (to quantify deposited spray mass/volume).
• Specification of meteorological measurement and acceptance conditions (wind speed, stability) for valid field trials.
• Guidance on test repetitions, data reporting and presentation to support risk assessment and comparative classification.

Typical use and users

This standard is used by: manufacturers and test laboratories conducting field evaluations of sprayers and nozzles; research organisations studying spray drift and deposition; regulatory agencies and risk assessors evaluating off‑target exposure; and environmental consultants preparing drift assessment reports. It is applied when standardized, comparable field data on drift are required for product assessment, equipment development or regulatory submission.

Related standards

ISO 22866 is part of a family of ISO documents on crop protection equipment and spray measurement. Related standards include ISO 22856 (laboratory wind‑tunnel methods for spray drift potential), ISO 24253 (spray deposition tests for field crops — measurement in horizontal plane and in crop), ISO 22522 (field measurement of spray distribution in tree and bush crops) and other ISO/TC 23/SC 6 test‑method standards addressing drift classification and nozzle/sprayer testing. These related documents provide complementary laboratory methods, deposition tests and classification schemes.

FAQ

Q: What is this standard?

A: ISO 22866:2005 is an International Standard that defines field methods and principles for measuring spray‑droplet drift from crop protection application equipment to allow comparable, repeatable drift assessments.

Q: What does it cover?

A: It covers field‑based measurement procedures for drift quantification (layout, samplers, distances, meteorological conditions and reporting) with detailed focus on tractor‑mounted, trailed and self‑propelled boom sprayers and on sprayers used in bush and tree crops; it sets out standard measurement distances and reporting practices to support risk assessment.

Q: Who typically uses it?

A: Test laboratories, sprayer and nozzle manufacturers, researchers in spray technology and environmental exposure, regulatory authorities and consultants performing drift risk assessments or comparative testing.

Q: Is it current or superseded?

A: The 2005 edition is the published edition; it has been subject to periodic review and was confirmed in ISO's review cycles. Users should check national adoption notices or ISO updates for the latest confirmation or revision activity before relying on the standard for regulatory purposes.

Q: Is it part of a series?

A: Yes — ISO 22866 belongs to the set of ISO standards developed by ISO/TC 23/SC 6 on equipment for crop protection and spray measurement; complementary parts address laboratory wind‑tunnel methods, spray deposition tests, drift classification and other test methods (for example ISO 22856, ISO 24253, ISO 22522).

Q: What are the key keywords?

A: Spray drift, droplet drift, deposition, boom sprayer, field test methods, plant protection equipment, drift measurement, off‑target contamination.
