Overview

ISO 8437-4:2019/FDAmd 1:2022 is an important international standard providing additional national and regional safety requirements and test procedures specifically for combustion engine powered snow throwers. This includes both pedestrian-controlled and ride-on models. The standard is part of the wider ISO 8437 series dedicated to snow thrower safety, complementing parts 1 through 3.

Prepared by ISO Technical Committee ISO/TC 23/SC 13 in collaboration with CEN/TC 144, the document ensures compliance with key safety directives such as the European Machinery Directive 2006/42/EC. The amendment reflects evolving regional requirements, enhancing operational safety and regulatory compliance in snow thrower manufacturing and use.

Key Topics

• Engine Speed Control
  Snow throwers must be designed so that the engine speed cannot exceed the manufacturer’s maximum operating speed by any simple adjustment or control. This prevents unsafe engine operation and potential hazards during use.

• Fixed Guards and Fastening Systems
  All fixed guards must be secured with fastening systems that require tools to open or remove. These fasteners must remain attached to the guard or snow thrower when removed to prevent loss. Guards should not remain partially fastened; proper securing is mandatory to ensure operator safety.

• Noise Emission Testing
  The standard references EN ISO 3744:1995 for determination of sound power levels, aligning with the Outdoor Noise Directive 2000/14/EC. This ensures noise measurements are consistent and conform to established environmental noise regulations.

• Conformity to Machinery Directive 2006/42/EC
  The standard includes provisions for presumption of conformity with essential health and safety requirements under this directive, covering areas such as control systems, fixed guards, noise, vibration, radiation, and machine marking.

Applications

ISO 8437-4:2019/Amd 1 is used by:

• Manufacturers of combustion engine snow throwers to integrate national safety requirements in design and testing processes.
• Regulatory authorities ensuring compliance with regional safety and environmental regulations.
• Testing laboratories performing conformity assessments on snow throwers, including engine speed controls, guarding, and noise emissions.
• Safety auditors verifying that snow throwers meet mandatory fastening and guarding standards to reduce operator risks.

This standard facilitates safer product development, reduces liability risks, and aids in regulatory approvals across multiple jurisdictions.

Related Standards

ISO 8437-4:2019/FDAmd 1 should be used alongside other parts of the ISO 8437 series and relevant related standards, including:

• ISO 8437-1:2019 – Terminology and common tests for snow throwers
• ISO 8437-2:2019 – Safety requirements and test procedures for pedestrian-controlled snow throwers
• ISO 8437-3:2019 – Safety requirements and test procedures for ride-on snow throwers
• EN ISO 3744:1995/2010 – Acoustics – Determination of sound power levels
• ISO 4871:1996 – Noise declaration and verification
• ISO 12100:2010 – Safety of machinery – Risk assessment and risk reduction principles
• ISO 16063:2015 – Calibration of vibration and shock transducers
• Directive 2006/42/EC – European Machinery Directive for essential health and safety requirements

By following the amendment, manufacturers and users ensure products meet the latest international safety standards and regional legal requirements, supporting global market access and user safety.

Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
