2、erstellen Supersedes November 1979 edition. In keeping with current practice in standards published by the International Organization for Standardization (/SO), a comma has been used throughout as the decimal marker. 1 Scope and field of application This standard establishes a system of designating

3、lubri- cants and of marking lubricating containers and equipment, and lubricating points,the aim being to prevent damage due to the wrong lubricant being used for a particular appli- cation. If containers used for shipping lubricants are also to be marked, the same symbols should be used. See DIN 86

4、59 Part 1 for identification of lubricating points on machine tools. 2 Designation and marking 2.1 General Lubricants are designated by a code consisting of letters and numbers enclosed in a geometrical symbol (to identify the class of lubricant). Where such code is used for marking purposes, the ba
