GB/T 40302-2021 《Plastics—Determination of burning behaviour of thin flexible vertical specimens in contact with a small-flame ignition source》 Related products

GB/T 40302-2021 is used to determine the combustion performance of plastic vertical soft and thin samples when they are in contact with a small flame source. The standard clarifies the testing principle, specifies the technical parameters of small flame source devices, such as combustion devices, and clarifies the size and shape requirements of the sample preparation. Standardize the test process, including the contact position and time of the flame and the sample, observe and record the combustion phenomenon of the sample, such as whether it ignites and the spread of the flame. Through this standard, the combustion characteristics of plastic soft and thin products in the event of a small flame can be effectively evaluated, providing a reliable test basis for plastic production and application industries, and helping to improve product safety.
