Development Details for NLGI's New
HPM Grease Specification
By Joe Kaperick and Chuck Coe
HISTORY AND GOALS
The National Lubricating Grease
Institute (NLGI) currently licenses
lubricating grease through its Certification Mark program, which includes
the well-known GC-LB Performance
Classification. The GC-LB specifications were developed beginning in
1966 and finally published in 1989
as ASTM D4950. This certification
program has provided an internationally recognized grease specification
for grease and bearing manufacturers,
users and consumers since that time.
Today, over 300 products are licensed
by 85 companies. Although originally
conceived as an automotive chassis
and wheel bearing specification for

aftermarket-service greases, GC-LB
today is still recognized as a mark of
quality for grease specifiers.
In 2015, NLGI began efforts to
upgrade the GC-LB specification due to
advancements in materials, technologies
and applications, as well as precision
issues with several of the D4950 tests.
In July 2019, the decision was made to
develop a new set of specifications with
higher performance and broader utility
to the industry. These new specifications
evolved into what today is known as
NLGI's High-Performance Multiuse
(HPM) Grease Specifications. An
additional goal was to define greases
that meet core HPM specification and
subcategories with tests and limits for
enhanced performance in the areas
outlined in Figure 1.
FREQUENTLY ASKED QUESTIONS
Will HPM require a certain thickener type or base oil type or additive
chemistry?
The answer is no. There is no aspect
of a grease formulation's chemistry that
is part of the new HPM grease specifications. Since the new specifications
are focused on the performance aspect
of the greases, there is no restriction
put on the raw materials, including
thickener type, base oil, additives or
manufacturing processes used to create
a product certified as an HPM grease.
