GB/T 13477.4-2017 specifies the method for measuring the extrusion of the original Encasement single component sealing material of building sealing materials. The standard specifies the requirements of test equipment, such as extrusion testers. Detailed description of the operation process of extruding the single component sealing material from the Encasement under the specified pressure and time under the maintenance of the original Encasement state. Through the measurement of the extrusion amount, the difficulty of extrusion of the sealing material can be intuitively evaluated. This provides a mass reference for the convenient use of sealing materials in building construction, ensuring that the sealing material can be extruded smoothly during construction, and ensuring the construction efficiency and sealing effect of the sealing project.
