STMC stands for the Standardized Test Methods Committee. The International Imaging Technology Council (Int'l ITC) administers the STMC program, assures its proper usage and polices against misuse of the STMC program and logos. For more than a decade, the STMC symbol has been the remanufacturing industry's indicia of quality. The test methods are used to evaluate toner printer cartridge performance. STMC uses certain ASTM test methods to evaluate a finished cartridge in comparison to another cartridge, typically an OEM cartridge.
