GB/T 17650.1 - 2021 specifies the method for the determination of the total amount of haloic acid gas during the combustion of cable or optical cable materials. The standard specifies the test principle, through a specific device to make the material combustion and collect the generated gas. Specify the specifications and performance requirements of the required instruments, such as combustion furnaces, gas absorption devices, etc. Specify the selection, preparation and combustion test procedures of the sample, including combustion temperature, time control, gas absorption and detection steps. With this standard, the total amount of haloic acid gas released by the combustion of cable or optical cable materials can be accurately determined, providing a key basis for evaluating its hazards in fires, ensuring public safety and guiding Product Research & Development.
