GB/T 22906.9-2008 "Testing of cores - Part 9: Determination of flat crush resistance" specifies the method for determining the flat crush resistance of paper cores, applicable to various types of paper cores. According to the standard, after sampling and conditioning under specified temperature and humidity, a compression testing machine is used to apply uniform pressure to the specimen until it collapses. The maximum pressure value is recorded to calculate the flat crush resistance. The standard defines the loading speed, specimen dimensions, and result representation, providing a basis for evaluating the compressive performance of paper cores.
