Overview

The FprEN ISO 19932-1 standard, titled "Equipment for crop protection - Knapsack sprayers - Part 1: Safety and environmental requirements", provides essential safety and environmental guidelines for the design and manufacture of knapsack sprayers used in agriculture, forestry, and horticulture. Published by the European Committee for Standardization (CEN) and aligned with ISO guidelines, this standard aims to enhance operator safety while minimizing environmental impact during the application of plant protection products.

This standard specifically addresses various types of knapsack sprayers carried on the back or shoulder and focuses on lever-operated, compression, and engine- or motor-driven sprayers with a nominal tank volume exceeding 6 liters. It excludes knapsack combustion engine-driven air-blast sprayers and pre-existing models manufactured before the standard's publication. By implementing FprEN ISO 19932-1, manufacturers ensure compliance with international safety obligations and environmental protection measures.

Key Topics

• Scope and Applicability
  Defines the types of knapsack sprayers covered, including design, construction, and safe operational use related to plant protection product application.

• Safety Requirements
  Specifies essential safety features such as harness design, spray tank integrity, control mechanisms, hoses, filters, spray lances, and nozzles to prevent operator hazards and environmental contamination.

• Environmental Protection
  Establishes guidelines to minimize spray drift and unintended dispersal of chemicals into the environment during operation.

• Specific Requirements by Sprayer Type

  • Lever-operated sprayers: Tank specifications and operating controls.
  • Engine- or motor-driven sprayers: Additional requirements including fuel tanks, exhaust systems, power-driven components, noise, vibration, and electromagnetic considerations.
  • Compression sprayers: Specific harness and tank design criteria.

• Information for Users
  Manufacturers must provide clear instructions covering safe working practices, technical data, markings, and warnings related to residual risks.

• Hazard Identification
  Annexes include detailed lists of significant hazards and correlation with EU directives ensuring alignment with broader legislative frameworks.

Applications

FprEN ISO 19932-1 is critical for agricultural machinery manufacturers, distributors, and end-users tasked with the handling and operation of knapsack sprayers. The benefits include:

• Enhancing Operator Safety: By adhering to ergonomic harness designs and functional control specifications, operators experience reduced physical strain and operational hazards.

• Ensuring Environmental Responsibility: Compliance minimizes chemical drift and environmental contamination, supporting sustainable crop protection practices.

• Regulatory Compliance: Aligns product design with EU Machinery Directive and other international safety and environmental regulations, facilitating smoother market access and legal adherence.

• Improved Product Reliability: Standardized verification methods ensure durable and safe equipment performance under normal and foreseeable misuse conditions.

This standard is particularly relevant in agriculture, forestry, and horticulture industries, where handheld crop protection equipment is extensively used.

Related Standards

FprEN ISO 19932-1 references and complements several international standards that support comprehensive crop protection equipment safety:

• ISO 5681 – Crop protection equipment vocabulary ensuring consistent terminology.
• ISO 12100 – General machinery safety principles including risk assessment and reduction.
• ISO 14982 – Electromagnetic compatibility requirements for agricultural machinery.
• ISO 3767-5 and ISO 3864-1 – Safety signs and graphical symbols for operator controls.
• ISO 5682-1 – Test methods for sprayer nozzles ensuring functional reliability.
• ISO 22868 – Noise test methods for forestry and gardening machinery.

Manufacturers are advised to consult these interconnected standards alongside FprEN ISO 19932-1 to design and certify compliant, safe, and efficient knapsack sprayers.

---

By following the requirements set forth in FprEN ISO 19932-1, stakeholders can ensure that knapsack sprayers used for crop protection meet rigorous international standards, safeguarding human health and the environment while maintaining operational effectiveness.

than 6,0 l.
It does not apply to knapsack combustion engine-driven air-blast sprayers according to ISO 28139.
This part of ISO 19932 deals with all significant hazards, hazardous situations and hazardous events
relevant to knapsack sprayers when they are used as intended and under conditions of misuse which
are reasonably foreseeable by the manufacturer (see Annex A), excepting the hazards arising from:
— static electricity;
— explosion or fire from chemicals for spraying; and
— insufficient structural integrity.
This document does not cover electromagnetic compatibility (EMC) requirements.
