HPM Grease Licensing Program


A New Standard for the Grease Industry

The High-Performance Multiuse (HPM) Grease Program is a licensing and product certification program for greases used in various lubricating applications. The HPM and associated specifications were developed by NLGI, in conjunction with grease users and grease specifiers, including original equipment manufacturers (OEMs) who were interviewed during the specification setting process.  The result was a High-Performance Multiuse (HPM) grease specification introduced in November 2020. The specification’s limits are “challenging yet achievable” in order to set a new performance standard that grease users and specifiers can utilize for selecting greases to use in their applications.

HPM Grease Spec

Since greases in some applications must perform in certain conditions (e.g. low temperature or exposure to liquids), the HPM grease specification defines different (tags) sub-categories with additional enhanced performance requirements.  In these sub-categories, a grease must meet the performance of the core HPM grease specification plus the additional performance requirements related to:

  • Water resistance (HPM+WR), and/or 
  • High load-carrying capacity (HPM+HL), and/or 
  • Salt water corrosion resistance (HPM+CR), and/or 
  • Low temperature performance (HPM+LT).  

Each tag can be added separately or in combination with other tags.  For example, one grease may meet the core HPM specification while another may meet the core plus all four tags:  HPM+WR+HL+CR+LT

How We Do It

Greases certified in the program are submitted with test data to show that they meet the performance standards related to parameters such as wear resistance, structural stability, oxidation resistance, elastomer compatibility, and corrosion resistance. Since the HPM specification limits define the grease’s performance, the HPM Grease Program is “chemistry neutral”. There are no formulation requirements for the greases to meet these specifications. Innovations in grease formulating are welcomed by the program in order to continuously improve the performance of greases in the market.

NLGI is a nonprofit trade association founded in 1933 by pioneers of the lubricating grease industry. The National Lubricating Grease Institute (NLGI) was established with the goal of providing education, scientific and technical information, expert advice, profitable partnerships and a global forum for ideas and innovation. NLGI’s mission is “to provide resources relevant to the needs of the global grease community.” 

The Center for Quality Assurance (CQA) administers the program on behalf of NLGI. Read more here.
