About MMM method

About metal magnetic memory method

The metal magnetic memory method has been developed practically and theoretically for more than 35 years. The method and the appropriate inspection instruments are used at more than 1200 enterprises of Russia. The method became widespread in 46 countries of the world. The International Standard ISO 24497-1:2007(E), 24497-2:2007(E), 24497-3:2007(E) on the metal magnetic memory method is approved in 2007 as a result of positive voting among 18 IIW member countries and more than 10 ISO Committee countries.
