USSR SPECIFICATION SYMBOIS
FOR CONSISTENT LUBRICANTS COST 3127-46
Petroleum Industry B-24
1. This standard sets up specification symbols for consistent lubricants
that are made by thickening mineral oils with soap or solid hydrocarbons and
are used for lubricating and protecting the surface of various mechanisms against
corrosion.
2, Specification symbols designate the field or range and the technique or
conditions for applying consistent lubricants.
3, There are two classes of consistent lubricants by field of application:
Class 1. Universal lubricants; for groups of mechanisms in any field
of application.
,Glass 2. Special lubricants; for particular mechanisms in a certain
fie'3 of application.
4. Class 1 lubricants, the universal lubricants, are conventionally speci-
fied by a letter "U." Additional letters indicate lubricant types according to
their inherent and specific properties.
For denoting universal lubricants possessing more than one forniubri~
and characteristic property, one more letter is to be added to "U";
cants possessing two such characteristic properties, twc letters, and so on con-
secutively, in conformance with the following directive t~tr enumerating different
types of lubricants.

5, Class 2 lubricants, the special lubricants, are conventionally speci-
fied by one letter denoting the field of their application (types) and the ma-
chine lubricated or the conditions of the application.
6. Specification symbols for fields of application are established as
follows:
