SIST EN ISO 19932-2:2025 PDF

Overview

EN ISO 19932-2:2025 / ISO 19932-2:2025 - "Equipment for crop protection - Knapsack sprayers - Part 2: Test methods" specifies standardized test methods to verify requirements of ISO 19932-1:2025 for knapsack sprayers carried on the back or shoulder and intended for use with plant protection products. It applies to lever-operated, compression and engine/electric motor-driven knapsack sprayers using hydraulic pressure atomization with a nominal volume > 6.0 L. It is not applicable to combustion engine-driven air‑blast sprayers covered by ISO 28139:2019+2019A1:2024.

Key topics and technical requirements

The standard defines practical, repeatable test procedures and reporting requirements, including:

• General test conditions and test liquids/equipment needed for reproducible results.
• Functional tests: reliability of spray liquid shut-off devices, spray output measurement, filling and emptying performance.
• Structural and user-safety checks: load-carrying straps and fixation tests, harness absorbency, and stability.
• Containment and emissions tests: leakage tests, pressure tests and measurement of external surface deposit and total residual liquid.
• Performance-specific tests: drop tests, centre of gravity determination, filling rate and contents gauge accuracy.
• Specific procedures by sprayer type: separate methods for lever-operated, compression and engine/motor-driven units.
• Documentation: prescribed test report content and informative annexes (examples of preconditioning, test devices and report templates).

Applications and who uses this standard

EN ISO 19932-2:2025 is used to:

• Verify design and safety claims during product development and type approval.
• Support conformity assessment and certification against ISO 19932-1:2025 and relevant EU machinery regulations (references in Annex ZA).
• Provide standard test protocols for independent test laboratories and manufacturers’ quality control.
• Guide procurement professionals, safety officers and agricultural equipment inspectors in evaluating knapsack sprayer performance and operator exposure risk.

Typical users: manufacturers, test laboratories, conformity assessment bodies, regulatory authorities, agricultural equipment specifiers and health & safety engineers.

Related standards and regulatory context

• ISO 19932-1:2025 - requirements for knapsack sprayers (to be used in conjunction).
• ISO 28139:2019+2019A1:2024 - covers combustion engine-driven air‑blast sprayers (excluded here).
• Relationship to EU Directive 2006/42/EC (Machinery Directive) is noted in Annex ZA - compliance with EN ISO 19932-2 can support conformity with essential safety requirements.
