The ASTM D1475-2020 standard specifies a method for determining the density of liquid Coatings, inks and related products. Density is an important property for material identification and quality control. This method is particularly suitable for high viscosity fluids or components with high volatility. By accurately measuring density, the mass of Coatings and whether there are problems, such as mis-charging, can be detected. The standard provides a high-precision density Measuring method to ensure an accurate assessment of hiding power and is suitable for work with different accuracy requirements.
