FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Lubricants
and Related Products Sectional Committee had been approved by the Petroleum, Coal and Related Products
Division Council.
Lithium Complex Greases for industrial purposes are being increasingly used all over the world for high
temperature multipurpose applications where conventional lithium based greases fail to provide satisfactory
levels of performance.
In India manufacture of multipurpose lithium complex greases commenced a few years ago and today these
greases are being extensively used in steel plants, heavy engineering industries and several otherspecialized
applications.
Considering that 2000 to 3000 MTPA of lithium complex greases are being produced and also considering that
a very large variation in the properties of these greases is possible, a need has been felt for formulation of a
National Standard for Lithium Complex Greases which can be used for industrial applications. Two grades
namely, Grade A and Grade B have been covered in the standard which corresponds to the NLGI grades 2and
3 respectively.
For the purpose of deciding whether a.particular requirement of this standard iscomplied with, the final value,
observed or calculated, expressing the result of test or analysis, shall be rounded off in accordance with
IS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained inthe
rounded off value should be the same as that of the specified value in this standard.
