GB/T 19724-2020 Forestry machinery—Portable chain-saws and brush-cutters—Exhaust system-caused fire risk
Abstract
This standard specifies the technical requirements and test methods for the emission systems in portable chainsaws and brushcutters that are prone to fire hazards.
The technical requirements include:
——The maximum temperature of the exhaust gas and the surface of the emission system;
——The maximum pore size of the screen-type spark arrester;
——Restrictions on deposits;
——Requirements for durability and reliability.
The test methods include:
——Test methods for the temperature of the exhaust gas and the surface of the emission system;
——Methods for determining the pore size of the screen-type spark arrester.
Note: Except for the screen-type spark arrester, this standard does not specify methods for measuring the limit size of carbon particles in emissions.
