The standard "IP 530-2006 Density Pressure Cup Method for Determination of Grease Density" specifies the specific method for determining the Density of oils and fats using the Density Pressure Cup Method. This method is suitable for the determination of Density of various oils (including vegetable oils, animal oils, etc.) and is one of the common techniques for measuring the mass and purity of oils and fats. The standard describes in detail the equipment required for the test, the operation steps, the data processing and the way the results are expressed. Through the Density Pressure Cup Method, the Density of oils and fats can be accurately measured at a certain temperature, so as to infer their physical properties and composition. The standard is of great significance for ensuring the conformity and quality control of oil products and is widely used in food, cosmetics, petrochemicals and other fields.
