FMSI ® - Friction Materials Standards Institute



In 1948 the Friction Materials Standards Institute was founded as a trade association of automotive aftermarket friction manufacturers. Since that time it has performed a very valuable service for the automotive aftermarket – the creation of a standardized part numbering system for brakes and clutch facings.


Primary Mission:
Maintain and enhance this standardized part numbering system for all on highway vehicles in use in North America.  Not only do the manufacturing members have the right to use this system, but their customers also have that right. From manufacturer through retailer / installer one part number is used as the standard and as a common language – the FMSI® Number.

Secondary Mission:
Disseminate to its members such scientific, engineering, technological, statistical and other relevant information as it may obtain in the public domain pertaining to brake linings, clutch facings, and the industry.
In most industries each company must perform this service by themselves at substantial cost. Then they must coordinate that part number with their customers at additional expense to both. Because the members support and cooperate in this effort, the entire industry has benefitted at a relatively low cost. Membership in FMSI® is open to any manufacturer of friction and related products covered by the trademarked FMSI® and FMS® part numbers. Other participants in this industry may be eligible for licensee membership.

Intellectual Property of FMSI®
In addition, FMSI® has also trademarked several of the part numbers that make up its standardized part numbering system.


All dues paying members of the Institute are authorized to use, within specified limits, these marks in connection with the order, purchase, offer or sale of friction materials identified by part number and drawing promulgated by the Institute. All use of these trademarks, whether actual or constructive, by anyone not paying dues to the Institute constitutes trademark infringement, unfair trade practice, and unjust enrichment. The Friction Materials Standards Institute will vigorously enforce its rights against any unauthorized use of its trademarks and copyrights.

Util has been a member of FMSI® since 1978, working closely with the organization to understand the automotive brake aftermarket and promote the spread of accurate, detailed information.
