Title:Testing Squeak and Itch Compatibility of Materials Pairs
Issuing Committee:Squeak And Itch Compatibility Task Force
Scope: This recommended practice defines test procedures for evaluating and characterizing material pairs, relative to squeak and itch performance. The included procedures are intended to facilitate material pair selection and optimize their performance through the application of coatings, surface texture, etc. The methodology employed utilizes acoustical interactions, frictional properties, and other metrics in simulated vehicle conditions
