4、tion should be the field of application. This criterion was adopted for lubricants (sec ISO 6743/0). In cer- tain circumstances, this criterion may not be appropriate; in such cases, a classification may be based on the type of product. This criterion was adopted for the fuels, which were classified
5、 firstly by type and secondly by end use (see ISO 8216/0). 3.2 The principle of this classification is based on assigning a prefix letter which characterizes the main classes of Petroleum products. In this classification System, products are designated in a uniform manner. The complete designation c
6、onsists of - the initials ISO; - the class of the Petroleum product or related product, designated by a letter (see the table in clause 4). This prefix letter shall be clearly separated from the other Symbols; - the category, designated by a group of letters (1 to 4), the first letter of which alway

Any following letters taken separately may or may not have a significance of their own but will be defined, in each case, in the International Standard giving the detailed classification of the family or category concerned; - numbers, which may be added to complete the desig
8、nation. Their significance will be defined in the rele- vant International Standard. The code shall be presented in the following general form : ISO - CLASS - CATEGORY - NUMBERS (if any) or in the abbreviated form : CLASS - CATEGORY - NUMBERS (if any). 1 Copyright International Organization for Stan
