The objective is to establish a standard, which certifies that an individual possesses a defined level of expertise in the field of grease. Certification indicates that NLGI recognizes the individual as a grease expert.
Certification is a useful tool for employers to screen potential employees and for OEMs and end users to ensure that consultants and suppliers are qualified to make grease related recommendations. Certification entitles the individual to use the CLGS® designation, which can provide a professional advantage in obtaining employment, promotions, and new business opportunities. NLGI will post a list of the individuals achieving CLGS® certification on the NLGI website.
• Lubrication Regimes
• Viscosity and Viscosity Index
• Tribology
