There are different Quality Class Standards in the industry. Most commonly followed is class 1 & 2.
Class 1 is for General Electronic Products and for testing and verification of Designs.
Class 2 is for Dedicated Service Electronic Products such as communication equipment,sophisticated business machines, instruments where high performance and extended life is required and for which uninterrupted service is desired.
Class 3 products are used in certain types of medical, aeronautics, and military applications for which uninterrupted and high reliability service is required.
