Full title and description

St ISO 4254-1-2013 Amd1-2021 — Agricultural machinery — Safety — Part 1: General requirements — Amendment 1. This document is the first amendment to ISO 4254-1:2013 and updates/clarifies selected safety requirements, editorial points and verifications that apply to the general safety provisions for agricultural machinery.

Abstract

ISO 4254-1:2013 sets out safety requirements and means of verification for the design and construction of self‑propelled (ride‑on), mounted, semi‑mounted and trailed agricultural machines to address typical hazards, hazardous situations and events occurring during intended use and reasonably foreseeable misuse. Amendment 1 (2021) provides technical corrections, clarifications and limited additions to the 2013 edition to ensure the standard remains aligned with current safety practice; users should consult the amendment text for precise changes.

Scope

The amendment applies to ISO 4254-1:2013 and addresses the general safety requirements for agricultural machinery — including self‑propelled ride‑on machines and mounted, semi‑mounted and trailed implements — by updating, clarifying or correcting clauses of the 2013 edition. The base part (ISO 4254-1:2013) covers hazards typical for most agricultural machines and specifies the type of information on safe working practices and residual risks that manufacturers must provide. Users should refer to the full amendment document for precise clause-level changes.

Key topics and requirements

• Clarifications and corrections to general safety requirements from ISO 4254-1:2013 (textual and technical amendments).
• Requirements and verification methods for guarding and protection of hazardous machine parts and power transmissions.
• Operator controls, start/stop provisions and emergency stopping information where applicable.
• Information for use — marking, warnings and instructions to address residual risks and safe operating practices.
• Risk assessment and mitigation expectations aligned with general machinery safety principles.
• Updates to definitions, references and normative cross‑references as needed to remove ambiguities in the 2013 text.

Typical use and users

Primary users are manufacturers and designers of agricultural machinery, product safety and compliance engineers, test laboratories, notified bodies and certification organizations, regulatory authorities that reference ISO standards for national/regional rules, and standards developers preparing national adoptions or translations. The amendment is used alongside ISO 4254-1:2013 when assessing conformity or preparing technical documentation and user information.

Related standards

ISO 4254-1 is part of the ISO 4254 series on agricultural machinery safety (other parts cover particular machine types and hazards). Related and commonly referenced standards include ISO 12100 (general principles for risk assessment and risk reduction for machinery) and other part‑specific ISO 4254 documents. National adoptions (EN/ISO or designated national “identical” publications) and sector‑specific guidance documents may also reference this amendment.
