The "IP PM-CS-2003 Pressure Cup Method for Determining Density of Grease and Fat" standard provides a test method for the determination of Density of grease, using the Density Pressure Cup Method. This method evaluates the physical properties of grease by measuring the Density of grease at a specific temperature and pressure. The Density Pressure Cup Method uses a sealing vessel to determine the mass to volume ratio of grease under a certain pressure to obtain its Density value. The standard specifies in detail the test procedures, equipment requirements, operating conditions and method of calculating results to ensure the accuracy and repeatability of test results. This method is widely used in the quality control, production testing and product standardization of oil products, especially for evaluating the Density characteristics of oil products such as vegetable oils and animal oils.
