GB/T 25278-2010 specifies the method for measuring the fluidity of plastics by capillary tubing and slit die Rheometer. The standard introduces the scope of application and working principle of the two Rheometers, and clarifies the determination process, covering the steps of sample preparation, instrument debugging, test condition setting, etc. Detailed instructions on how to obtain key data such as shear rate and shear stress, and calculate plastic flowability parameters accordingly. Provide unified specifications for plastic production, processing enterprises and scientific research institutions to help accurately grasp the flow characteristics of plastics, optimize production processes, and ensure the mass of plastic products.
