Scope
Main technical content: This standard specifies the method of determining the average linear expansion coefficient of carbon fiber in the axial direction using the push rod differential method, including the method principle, samples, test instruments, test procedures, determination of system correction parameters, calculation of test results, and test reports. This standard is applicable to the testing of the average linear expansion coefficient of adhesive-based carbon fiber, polyacrylonitrile-based carbon fiber, and general-grade asphalt-based carbon fiber in the temperature range of 20 to 900℃. Other organic, inorganic fibers or metal wires can also refer to this method. This standard is not applicable to mesophase asphalt-based carbon fiber.
