Testing system to ensure product safety

Oriental Motor products comply with all major safety standards and laws in Europe, North America, Asia and other parts of the world. To ensure the safety of our products, we have established a product safety laboratory and an EMC test center at our Tsukuba Plant to test and evaluate compliance with safety standards and laws.
The product safety testing laboratory is independent from the business divisions and is governed by the international standard ISO/IEC 17025 Laboratory Management System, and is compliant with the European EN standards by the VDE (German Institute of Electrical Engineers), and by UL (Underwriters Laboratories) for American UL and Canadian CSA standards. At the same time, it is registered as an IECEE CTF Stage 2 laboratory, which conducts testing for IEC standards, the international standard for electrical equipment.
Rigorous and objective testing is conducted in-house, and the results are immediately fed back into product development and design. Through this product safety testing system, Oriental Motor offers safe products that can be used with confidence all over the world.

Testing system to ensure product reliability

The Reliability Test Building at the Tsukuba Plant has a variety of equipment for environmental testing, with dedicated engineers conducting the tests.
After testing is completed, a careful investigation and analysis is also performed to ensure that the product has the intended strength. The Design Division uses the results of this research and analysis to improve and refine the product.
Repeated design evaluations carried out in this manner enhance product reliability and provide customers with products that they can use with confidence.
