---Added China's additional requirements for the "marking" of step-type snow throwers and mount-type snow throwers (see 4.1) to adapt to my country's technology condition;

---Replaced ISO 8437-2:2019 (see Chapter 5) with the normatively cited GB/T 43326.2-2023, the difference between the two documents the degree of consistency is modified to adapt to my country's technical conditions;

---Added China's information on "engine speed", "protection devices, guards, snow discharge troughs, deflectors and casings" and "electromagnetic resistance" of step-by-step snow blowers:

Additional requirements for interference, noise, and vibration (see 5.1) to adapt to my country's technical conditions;

--- Added normative references to GB/T 21398-2008 (see 5.1, 6:1) to adapt to my country's technical conditions;

---Replaced ISO 8437-3:2019 (see Chapter 6) with the normatively cited GB/T 43326.3-2023, the difference between the two documents the degree of consistency is modified to adapt to my country's technical conditions;

---Added China's information on "engine speed", "protection devices, guards, snow discharge troughs, deflectors and casings" and "electromagnetic resistance" of mount-type snow throwers:

Additional requirements for interference, noise, and vibration (see 6.1) to adapt to my country's technical conditions;

---Replaced ISO 3744 (see A:2 and A:6) with the normatively quoted GB/T 3767 to adapt to my country's technical conditions;

---Replaced ISO 11201 (see A:3 and A:6) with the normatively cited GB/T 17248.2 to adapt to my country's technical conditions;

---Replaced ISO 5008 (see B:3:2:2) with normatively cited GB/T 10910 to adapt to my country's technical conditions:

The following editorial changes have been made to this document:

---In order to coordinate with existing standards, the name of the document is changed to "Safety Requirements and Test Methods for Snow Throwers Part 4: National and Local District's Additional Requirements":

Introduction

Due to the particularity of the use environment and working objects of snow blowers, their products need to be highly adaptable and safe: my country's snow blower Production and usage are increasing year by year, so there is an urgent need to formulate safety standards for snow throwers to protect the interests of consumers and ensure their use:

the safety of the person:

GB/T 43326 is a Category C standard specified in GB/T 15706, that is, for step-type snow throwers and mount-type snow throwers powered by internal combustion engines:

Snow machines stipulate detailed safety requirements and test methods: GB/T 43326 is related to the following enterprises, institutions, individuals and related snow throwers:

Interested organizations and groups:

---Snow blower manufacturing company;

---Health and safety agencies (regulatory agencies, accident prevention agencies, market surveillance agencies), etc:;

---Snow blower consumers and users;

---Service providers, such as machine maintenance:

GB/T 43326 is intended to be composed of four parts: These four parts cooperate with each other to form the necessary and complete safety technical requirements for snow throwers:

Sum test method:

---Part 1: Terminology and general tests: The purpose is to provide relevant stakeholders with the technology of step-by-step snow throwers and mount-on snow throwers:

language and general test methods:

---Part 2: Step-by-step snow blower: The purpose is to provide relevant stakeholders with specific safety requirements and tests for step-by-step snow blowers:

method:

---Part 3: Mount-type snow blower: The purpose is to provide relevant stakeholders with specific safety requirements and testing for mounted snow throwers:

method:

---Part 4: Additional requirements for countries and regions: The purpose is to provide relevant stakeholders with relevant information on different countries and regions:

Additional requirements for GB/T 43326.1-2023, GB/T 43326.2-2023, and GB/T 43326.3-2023:

Snow blower safety requirements and test methods Part 4: Additional requirements for countries and regions

1 Scope

This document specifies additional national and regional requirements for internal combustion engine-driven step- and ride-on snow blowers: This document is intended to be related to GB/T 43326.1-2023, GB/T 43326.2-2023 and GB/T 43326.3-2023 are used together to meet the requirements of step-by-step and mounted all requirements and verification methods for snow blowers:

GB/T 43326 (all parts) is used to deal with major hazards related to normal use of snow blowers and the use reasonably expected by the manufacturer:
