Overview

EN ISO 8437-3:2021/prA1 is an amendment to Part 3 of the ISO 8437 series addressing safety requirements and test procedures for ride-on snow throwers. Adopted in parallel by CEN (SIST EN ISO 8437-3:2021/oprA1:2022), this draft amendment clarifies scope, operator-presence control behavior and protective housing requirements for combustion-engine powered ride-on machines. The amendment was prepared by ISO/TC 23, SC 13 and circulated as ISO 8437-3:2019/DAM 1:2022.

Key Topics

• Scope clarification: The amendment explicitly applies to combustion-engine powered ride-on snow throwers and indicates that compliance may require combined application of ISO 8437-1 and ISO 8437-4 to meet the full set of requirements.
• Operator-presence control (OPC): When OPC is achieved by a foot pedal, a generally forward or downward motion on the foot-actuated control shall produce clutch engagement. In addition, a right-foot OPC must be positioned outboard of the service brake pedal.
• Collector/impeller housing: The amendment replaces wording in subclause 4.3.1 to require that the housing extension (limit A) prevents line-of-sight between the exposed circumference of the collector/impeller and the defined operator position.
• Terminology update: The document standardizes spelling by replacing the word "tire" with "tyre" throughout the text to align with regional terminology used in the published document.
• Draft status and process: This document was circulated as a draft amendment for comment and approval and may be subject to change until formally published.

Applications

This amendment is practical and relevant for:

• Manufacturers designing combustion-engine ride-on snow throwers who need to ensure machine layouts comply with clarified OPC placement and housing shielding requirements.
• Test laboratories performing safety and compliance testing against ISO 8437 series requirements and the new amendment clauses.
• Compliance officers and certifiers coordinating national adoption (CEN/SIST) and ensuring documentation references the correct amended clauses.
• Safety engineers implementing operator protection systems and ergonomic placement of foot-actuated controls.

Related Standards

• ISO 8437-1 - referenced for complementary requirements across the series.
• ISO 8437-4 - used together with Part 3 to achieve full requirements for ride-on snow throwers.
• ISO 8437 (series) - consult the series list on the ISO website for other parts and cross-references.

For manufacturers and stakeholders, this amendment refines key safety interfaces-OPC behavior, housing shielding and consistent terminology-to improve operator protection and regulatory clarity when testing and certifying ride-on snow throwers.
