The TC119(Printed Electronics) of IEC was established on November 2011, and then JEITA established the “IEC Mirror Committee” based on guidance by the Ministry of Economy on December so as to build the internal consideration system. In addition, “Printed Electronics Standard Committee” was established to support the investigating and promoting.

This new international standard is reflected the contents of JEITA ET-4501 which established on June 2015 strongly. And then, our test method is introduced as one of an example.
