Full title and description

Equipment for crop protection — Spraying equipment — Part 3: Test method to assess the performance of volume/area adjustment systems. This international standard specifies a standardized laboratory/test procedure to evaluate how accurately and consistently a sprayer’s volume-per-area (volume/ha or volume/area) adjustment system delivers the intended application rate across its operating range.

Abstract

ISO 5682-3:2017 defines a test method to assess the performance of volume/area adjustment systems for spraying equipment used in crop protection. It gives test conditions, measurement procedures and reporting requirements to quantify accuracy and repeatability of adjustment systems. The document is not applicable to manually operated knapsack sprayers or to aircraft sprayers.

Scope

Specifies a laboratory/field-compatible test method to evaluate volume-per-area adjustment systems fitted to spraying equipment used in crop protection and fertilizer application. The scope covers the procedures to set test conditions, select test points across the adjustment range, measure delivered liquid volumes or flows, calculate applied volume per unit area and determine accuracy and repeatability against nominal settings. The standard explicitly excludes manually-operated knapsack sprayers and aircraft sprayers; it replaces the earlier ISO 5682-3:1996 edition.

Key topics and requirements

• Definition of test conditions and environmental considerations for repeatable measurements.
• Selection of test points across the adjustment range (nominal settings to be assessed).
• Measurement techniques for flow/volume and area travelled to derive volume per unit area.
• Calculations to quantify accuracy (deviation from nominal) and repeatability (statistical dispersion).
• Criteria for pass/fail or reporting tolerances and standardized test-report content.
• Restrictions and applicability notes (not for knapsack or aircraft sprayers).

Typical use and users

Used by sprayer manufacturers and designers to validate and certify adjustment systems, by independent test laboratories and conformity assessment bodies for performance verification, and by regulatory agencies or equipment purchasers assessing product claims. Agricultural engineers, quality‑assurance teams and service organisations performing calibration and performance checks will also use the procedure.

FAQ

Q: What is this standard?

A: ISO 5682-3:2017 is an ISO test-method standard that defines how to assess the performance (accuracy and repeatability) of volume/area adjustment systems on spraying equipment used in crop protection.

Q: What does it cover?

A: It covers test setup, measurement procedures, calculation methods and reporting requirements to determine how closely a sprayer’s setting produces the intended volume per unit area across its operating range. It does not apply to manually carried knapsack sprayers or to aircraft-mounted sprayers.

Q: Who typically uses it?

A: Manufacturers, test laboratories, conformity-assessment bodies, regulatory agencies, agricultural engineers and service/maintenance organizations that calibrate or verify sprayer performance.

Q: Is it current or superseded?

A: ISO 5682-3:2017 supersedes ISO 5682-3:1996. The 2017 edition was subject to ISO’s systematic review process and is recorded as confirmed in the ISO lifecycle (reviewed/confirmed in 2022), so the 2017 edition remains the current valid edition.

Q: Is it part of a series?

A: Yes — ISO 5682 is a multipart series addressing different test methods and requirements for spraying equipment (for example, parts 1, 2 and 4 cover nozzle tests, transverse distribution and tank agitation respectively). Users often apply multiple parts of the series together when performing a comprehensive sprayer evaluation.

Q: What are the key keywords?

A: Spraying equipment, crop protection, volume per area, calibration, test method, adjustment system, sprayer performance, ISO 5682.
