What is the EN ISO 8437-2:2021 Test Standard?

EN ISO 8437-2:2021 is an international standard specifying safety requirements and testing procedures for pedestrian-controlled snow throwers powered by internal combustion engines. The main content of the EN ISO 8437-2:2021 standard includes:  

Scope of EN ISO 8437-2:2021  

EN ISO 8437-2:2021 applies to pedestrian-controlled snow throwers powered by internal combustion engines and is used in conjunction with ISO 8437-1 and ISO 8437-4 to meet all requirements and verification methods for such equipment.  

Exclusions from EN ISO 8437-2:2021  

This standard does not apply to:  

- Electric and battery-powered snow throwers;  

- Hand-held snow throwers;  

- Snow throwers and equipment used for airports or highways;  

- Machines intended for use in potentially explosive environments.  

Hazards Not Covered by EN ISO 8437-2:2021  

The standard does not address hazards related to:  

- Battery circuits exceeding 42V;  

- Starter motors connected to the mains power supply;  

- Grounding circuits for magnetos;  

- The working environment;  

- Electromagnetic compatibility (EMC).  

Machines Not Covered by EN ISO 8437-2:2021  

The standard does not apply to machines manufactured prior to its publication date.  

Significant Hazards, Hazardous Situations, and Events Covered by EN ISO 8437-2:2021  

The ISO 8437 series addresses significant hazards, hazardous situations, and events associated with snow throwers that can be reasonably foreseen by manufacturers during intended use and under reasonably foreseeable conditions.  

CE certification Process under EN ISO 8437-2:2021  

The CE certification process for snow throwers under this standard generally involves the following steps:  

1. Submission of CE Application: Manufacturers submit an application for CE certification to a notified body.  

2. Preparation of Test Samples and Technical Documentation: Manufacturers prepare the required test samples and technical files according to certification requirements.  

3. Testing and Rectification of Samples: Samples are tested in laboratories designated by the certification body. If test results do not meet the standard, rectifications are required.  

4. Review and Rectification of Technical Documentation: Submitted technical documentation is reviewed by the notified body, and any nonconformities must be rectified.  

5. Issuance of CE Certificate: Once sample testing and technical documentation review meet the requirements, the notified body issues a CE certificate.  

6. Affixing the CE Mark for Market Circulation: After obtaining the CE certificate, products can be affixed with the CE mark and sold within the EU market.  

Notes on the CE Certification Process  

The above steps outline the basic process for CE certification under EN ISO 8437-2:2021. It is important to note that specific procedures and requirements may vary depending on the certification body and product characteristics. Manufacturers should follow the specific guidance provided by their certification body during the actual process.
