Strong Emphasis on Quality Assurance System

The Reliability Testing Section of the Quality Assurance Dept. in Kyoto Techno Center conducts type testing for all new and re-designed products.

Evaluation test

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*1 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*2), and we conduct an official test instead of a simplified test.

Company standards Number of standards
Standards on the functions 42
Standards on the performance 33
Standards on the reliability 48
Standards on the mechanism 9
Total 132

*1. 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.
*2. VCCI (Voluntary Control Council for Interference by information technology equipment) :
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
