GB/T 5671-2014General purpose lithium lubricating grease for automobile (English PDF)

Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced GB/T 5671-1995 General Purpose Lithium Base Grease for

Automobile.

Compared with GB/T 5671-1995, this Standard has the major changes as follows.

--- Delete "electric generator" in the application scope;

--- Add the low temperature torque index; and delete the similar viscosity index;

--- In the impurity items; change the number of particles with diameter10µm above

from the original no greater than 5000 pieces/cm3 into no greater than 2000

pieces/cm3; change the number of particles with diameter 25µm above from the

original no greater than 3000 pieces/cm3 into no greater than 1000 pieces/cm3;

change the number of particles with diameter 75µm above from the original no

greater than 500 pieces/cm3 into no greater than 200 pieces/cm3;

--- Express the anticorrosive property according to the result expressing mode

stipulated in the newly revised GB/T 5018, changing from the original "no more

than Grade-1" into "qualified";

--- Add the No.3 consistency grades and technical indicators for the No.3 general

purpose lithium lubricating grease for automobile;

--- Add Chapter 3 Classification and Marking;

--- Add Chapter 5 Inspection Rules.

This Standard is not equivalent to the Japanese Industrial Standard JIS K2220-2003

Class-1 Lubricating Grease for Automobile Wheel Bearing in the aspect of consistency

degree.

This Standard was proposed by National Technical Committee for Standardization of

Petroleum Products and Lubricants (SAC TC/280).

The historical editions replaced by this Standard are as follows.

General Purpose Lithium

Lubricating Grease for Automobile

1 Scope

This Standard specifies the classification and mark, requirements and test methods,

inspection rules, marking, package, transportation and storage of the general purpose

lithium lubricating grease for automobile.

This Standard is applicable to the lubricating grease made by adding antioxidant and

antirust additives into the fatty acid lithium soap thick mineral base oil.

Products conforming to this Standard are applicable to the lubrication of friction parts

such as automobile hub bearings, chassis and water pumps operating at the working

temperature ranging from -30°C~120°C.
