ISO 4254-12:2012/Amd 1:2017

Overview

ISO 4254-12:2012/Amd 1:2017 is an important amendment to the international standard focusing on the safety requirements for agricultural machinery, specifically rotary disc and drum mowers, as well as flail mowers. Published by the International Organization for Standardization (ISO), this amendment updates the original 2012 Part 12 standard to ensure enhanced safety protocols and align with recent advancements in mower technology.

This amendment is critical for manufacturers, operators, and safety inspectors involved in the design, manufacturing, and use of rotary disc, drum, and flail mowing equipment. It emphasizes updated safety controls, placement of operational commands, and references to blade specifications.

Key Topics

• Updated Blade Specifications
  The amendment replaces the prior reference ISO 5718:2002 with the revised ISO 5718:2013. This refers to the specifications for blades used in rotary disc mowers, ensuring that blade safety and performance standards meet current technological advancements.

• Control Command Placement
  One of the main changes involves the positioning of control commands for mower adjustments. Commands must now be located on the top or sides, either at the front or rear of the mower, within a maximum horizontal distance of 550 mm from the machine’s external limits. This optimizes accessibility and operator safety.

• Applicability to Mounted Mowers
  For mounted mower configurations, the amendment instructs compliance with the positioning and safety standards specified in ISO 4254-1:2008, enhancing consistency across agricultural machinery types.

• Safety Compliance and Conformance
  The document underscores the importance of adhering to ISO/IEC directives and international collaboration for conformity assessment, making it a key reference for global safety compliance in agricultural machinery industries.

Applications

• Agricultural Equipment Manufacturing
  Manufacturers use this standard and its amendment as a guide for designing rotary disc, drum, and flail mowers that meet international safety requirements, reducing risk to operators and improving market acceptance.

• Operator Safety Training
  Safety officers and training supervisors leverage the requirements to educate operators about the correct use and adjustment of control commands to prevent injury during mower operation.

• Regulatory Compliance
  National and international regulatory bodies adopt ISO 4254-12:2012/Amd 1:2017 to establish or update legislation pertaining to agricultural mower safety, ensuring machinery placed on the market complies with the latest safety norms.

• Product Development and Innovation
  Engineers and product developers incorporate the updated blade standards and control placement recommendations into new mower models, fostering safer and more user-friendly agricultural tools.

Related Standards

• ISO 4254 Series
  Part 1 and other parts of ISO 4254 cover general safety requirements for agricultural machinery and provide complementary guidance for the safe design and use of other types of agricultural equipment.

• ISO 5718:2013
  This standard specifies the requirements for blades used in rotary disc mowers and is now the referenced blade specification for the amended Part 12.

• ISO/IEC Directives
  These guidelines shape the development, updating, and approval processes for ISO standards, ensuring the amendment is aligned with global standardization rules.
