This part of GB/T 17651.2-2021 focuses on the procedures and requirements for the determination of combustion smoke density of cables or optical cables. It first clarifies the determination principle, specifies the technical specifications of smoke density testing equipment, covering combustion boxes, optical path systems, etc. Detailed description of sample preparation, such as cable or optical cable interception and Installation method. Standardize the test process, including ignition operation, luminous flux Measurement time node setting, and calculate smoke density based on test data. The standard provides unified test specifications for cable and other industries to help evaluate product combustion smoke hazards and ensure fire safety in power, communication and other systems.
