The document discusses the DIN 51825 German grease classification system. It consists of 5 designations that provide information about the grease type, NLGI grade, upper operating temperature, water resistance, and lower operating temperature. For example, K1G-20 indicates an EP type grease with NLGI grade 1, operating temperatures from 0-90°C and -20°C, and water resistance up to 90°C. Table 2 further explains the third designation letter for upper operating temperature and water resistance ratings.
