Overview
EN ISO 8437-4:2021/A1:2026 - "Snow throwers – Safety requirements and test procedures – Part 4: Additional national and regional requirements – Amendment 1 (ISO 8437-4:2019/Amd 1:2026)" - is an essential amendment developed by CEN addressing safety and compliance for combustion engine powered snow throwers. This standard outlines the additional safety requirements and test procedures that are applicable at both national and regional levels, supplementing the general provisions in EN ISO 8437-1, 8437-2, and 8437-3.
The document ensures that manufacturers, importers, and regulatory authorities are equipped with specific guidelines to improve operational safety, mitigate noise and vibration emissions, and confirm conformity with European directives related to machinery. These additional requirements are critical for both pedestrian-controlled and ride-on snow throwers.
Key Topics
Additional Regional Requirements
This standard amendment focuses on extra national and regional requirements that build upon baseline international standards, ensuring greater harmonization across jurisdictions.Safety Requirements for Engine Speed
Snow throwers must be designed so that engine speed cannot exceed the manufacturer’s specified limit via any controls or simple adjustments, addressing safety and operational integrity for both pedestrian-controlled and ride-on machines.Noise and Vibration
- Noise Measurement: Testing and declaration of noise emission values must align with Directive 2000/14/EC and ISO 4871.
- Sound Power Level: The standard mandates the use of Directive 2000/14/EC Annex III Part A for determining sound power levels.
- Marking and Information: Clear requirements for how noise emission values are communicated and labeled on the machinery.
Conformity with EU Directives
The amendment provides a means for manufacturers to demonstrate presumption of conformity with essential health and safety requirements under Directive 2006/42/EC (Machinery Directive). This links the standard directly to regulatory compliance and product approval processes.
Applications
Manufacturing Compliance:
Manufacturers of pedestrian-controlled and ride-on snow throwers can use this standard to ensure their products meet safety, noise, and marking requirements specific to national or regional markets. This facilitates access to the European market and alignment with evolving regulatory expectations.Product Testing and Certification:
Organizations tasked with testing and certifying snow throwers can reference the procedures and requirements set out in EN ISO 8437-4:2021/A1:2026 to assess compliance, especially regarding engine control, sound levels, vibration limits, and information labeling.Regulatory Reference:
Governments and regulatory bodies reference these harmonized requirements to uphold safety and conformity in the market, guiding enforcement and public procurement.Risk Reduction:
Application of this standard helps reduce the risks associated with snow thrower operation, from uncontrolled engine speeds to excessive noise and vibrations, ultimately protecting users and bystanders.
Related Standards
To achieve full compliance and coverage, EN ISO 8437-4:2021/A1:2026 should be used together with other key standards, including:
- EN ISO 8437-1:2019 - Terminology and common tests for snow throwers
- EN ISO 8437-2:2021 - Pedestrian-controlled snow throwers
- EN ISO 8437-3:2021 - Ride-on snow throwers
- EN ISO 3744:2010 & EN ISO 4871:2009 - Methods for determining and reporting machinery noise
- EN ISO 12100:2010 - General principles for design and risk reduction
- Directive 2000/14/EC - Noise emission in the environment by equipment for use outdoors
- Directive 2006/42/EC - Machinery Directive for essential safety requirements
Proper integration and reference to these standards ensure comprehensive compliance for snow thrower design, manufacturing, and market entry within the European Economic Area.
