Overview

EN ISO 8437-4:2021/prA1 (ISO 8437-4:2019/DAM 1:2022) is an amendment that provides additional national and regional safety requirements and test procedures for combustion‑engine powered snow throwers. It is intended to be used together with:

• ISO 8437-1 (common terminology and tests), and
• ISO 8437-2 (pedestrian‑controlled snow throwers) or ISO 8437-3 (ride‑on snow throwers),
  to achieve the full set of safety requirements and means of verification for machines within scope.

This draft amendment was prepared by ISO/TC 23/SC 13 (Secretariat: ANSI) and is circulated under ISO/CEN parallel processing.

Key topics and requirements

• Scope clarification: Specifies that the amendment applies to combustion engine powered pedestrian‑controlled and ride‑on snow throwers when used with the relevant parts of ISO 8437.
• Engine speed control: New requirements (subclauses 4.2.2.5 and 4.2.2.6) require design features that prevent sustaining engine speeds above the manufacturer’s specified maximum by any control or by simple adjustments.
• Noise measurement and declaration:
  • Sound power level determination is aligned with Directive 2000/14/EC Annex III Part A (Basic Noise Emission Standard).
  • Noise emission declarations shall follow ISO 4871 and Directive 2000/14/EC.
  • Test documentation must include a reference to the noise test code used.
• Conformity with EU Machinery Directive: Annex ZA maps the standard to essential requirements of Directive 2006/42/EC, indicating how authors of machine documentation and manufacturers can demonstrate conformity (where the standard is cited in the Official Journal).

Practical applications

Who uses this standard:

• Manufacturers and OEMs designing pedestrian and ride‑on snow throwers to meet safety and regulatory requirements.
• Compliance engineers and product safety managers ensuring design controls (engine governors, interlocks) prevent overspeed conditions.
• Test laboratories performing noise, vibration and safety tests referenced by ISO 8437 series and Directive 2000/14/EC.
• Regulatory bodies and procurement teams evaluating machines for conformity with the EU Machinery Directive and national regulations.
• Service and maintenance teams using standardized test and declaration procedures to verify ongoing compliance.

Practical value:

• Reduces regulatory risk by aligning product design and test methods with EU directives.
• Standardizes noise measurement and declaration for clearer marketplace claims.
• Provides prescriptive design expectations (e.g., overspeed prevention) that improve operator safety.

Related standards

Key normative references listed in Annex ZA include:

• ISO 8437-1 / -2 / -3 (snow thrower series)
• ISO 3744, ISO 4871 (acoustics and noise declaration)
• ISO 12100 (risk assessment)
• ISO 11201 (emission sound pressure levels) These referenced standards support testing, noise measurement and conformity assessment for snow throwers.

Keywords: snow throwers safety, ISO 8437-4, engine speed control, noise emission, test procedures, Directive 2000/14/EC, Machinery Directive 2006/42/EC, pedestrian‑controlled, ride‑on, conformity.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
