Full title and description

ISO 4254-8:2018 — Agricultural machinery — Safety — Part 8: Solid fertilizer distributors. Specifies safety requirements and verification methods for the design and construction of mounted, semi‑mounted, trailed or self‑propelled solid fertilizer distributors intended for use by a single operator, and the information on safe working practices the manufacturer must provide.

Abstract

ISO 4254-8:2018, to be used together with ISO 4254‑1, addresses the significant hazards, hazardous situations and events relevant to solid fertilizer distributors used as intended and under foreseeable conditions. It excludes certain hazards (for example lighting, seating, travelling functions and rollover) and specific machine types (combined seed/fertilizer drills creating a trench, machines for granulated pesticides, pedestrian‑controlled and knapsack distributors). The document also identifies the type of information on safe working practices (including residual risks) that manufacturers must provide.

Scope

This standard specifies safety requirements and verification for full‑width solid fertilizer distributors, solid fertilizer broadcasters, distributors with oscillating tube and line‑distributors, and solid fertilizer distributors driven by an auxiliary engine, when used by one operator in agriculture. It applies to mounted, semi‑mounted, trailed or self‑propelled machines manufactured on or after the publication date. It is not applicable to machines manufactured before publication, nor to maintenance/repairs carried out by professional service personnel, nor to most environmental hazards (except noise). Where ISO 4254‑8 differs from ISO 4254‑1, the provisions of ISO 4254‑8 take precedence for the machines it covers.

Key topics and requirements

• Safety requirements and verification procedures specific to solid fertilizer distributors (feeding/distributing components, guarding, strength requirements for guards).
• Risk assessment and residual risk reduction following ISO 12100 principles (integration with ISO 4254‑1 as the general part for agricultural machinery safety).
• Specification of manufacturer information for safe use, including warnings and residual risk information.
• Listing of significant hazards relevant to these machines (Annex A) and exclusions of hazards/situations outside the standard’s scope (e.g., rollover, travelling functions, lighting, seating).
• Applicability remarks (excluded machine types such as combined seed/fertilizer drills that deposit in a trench, granulated pesticide distributors, pedestrian and knapsack distributors).

Key technical topics summarized from the standard text and annexes.

Typical use and users

Used by agricultural machinery manufacturers and designers to ensure product safety and regulatory conformity; by testing and certification bodies for type/acceptance testing; by safety engineers and maintenance planners to define safe operating procedures and information for users; and by procurement, regulatory and inspection authorities when assessing machine safety. Designers will apply ISO 4254‑8 together with ISO 4254‑1 and ISO 12100 to develop compliant equipment and user information.

Related standards

ISO 4254-8:2018 is part of the ISO 4254 series (safety of agricultural machinery) and is intended to be used together with ISO 4254‑1 (general safety requirements). ISO 12100 (general principles for design — risk assessment and risk reduction) is the overarching risk‑assessment standard typically referenced. ISO 4254‑8:2018 replaces ISO 4254‑8:2009.
