Strong emphasis on quality assurance system
Kyoto Techno Center has the Reliability Testing Section of the Quality Assurance Dept. to conduct a type test of all products released from
M-System. We conduct a type test to verify the quality on not only new products but also products of which we changed the design.
Our Quality Assurance Dept. conducts a prototype evaluation before releasing a new product. We validate the products based on the various regulations / standards and the company standards mainly classified into four categories. In addition, we conduct an EMC (*5) test as a part of the evaluation test.
Our anechoic chamber used for the EMC test is certified and registered by the official body (VCCI (*6) ), and we conduct an official test instead of a simplified test.

Anechoic chamber certified and registered by the official body
(VCCI (*6) )
A large shielded room of 6 m x 6 m where multiple tests can be conducted simultaneously
The EMC test required for M-System to acquire the CE marking has the following test items and all of them are conducted by our own facility at Kyoto Techno Center (Kizugawa-City, Kyoto).

(*5) EMC (Electro Magnetic Compatibility): Tests to check the effect by applying an electromagnetic noise to a device and to measure the electromagnetic wave and conductive common mode noise emitted from the device.
(*6) VCCI (Voluntary Control Council for Interference by information technology equipment): Formerly known as Voluntary Control Council for Information Technology Equipment. An industry organization in Japan that discusses the regulations on the radio waves emitted from the information technology equipment
