ISO9001 and IRIS certifications for Mitsubishi Electric’s Transmission & Distribution Systems Center temporarily suspended

Japan, Tokyo: Mitsubishi Electric Corporation has announced temporary suspension of ISO 9001 and IRIS certifications.

The suspension has been issued by LRQA Limited for the company’s Transmission & Distribution Systems Center.

Effective of 6 May, the suspension is issued in connection with the certain quality-related conduct for transformers rated 22k V 2 MVA or above at the Centers’ Ako Factory, as announced on 21 April 21. Mitsubishi Electric is currently taking corrective actions to enable the certifications to be promptly reinstated. The ISO 9001 certification (ISO:2015/JIS Q 9001:2015; registration number ISO 9001 – 0065200, ISO:2015/JIS Q 9001:2015; registration number ISO 9001 – 0067278) is an international standard for quality management systems. The IRIS certification (IRIS Certification™ rules:2017 and based on ISO/TS 22163:2017; registration number YKA4005338) is an international standard for the railway industry.

In the earlier notice, the company has announced internal investigations being conducted by the external Investigative Committee established by the company on 2 July 2021, revealed to the company on 1 April 2022 that several inspections of transformers rated 22 kV 2 MVA or above manufactured at Mitsubishi Electric’s Transmission & Distribution Systems Center in Ako, Hyogo Prefecture, did not fully comply with customer-requested testing standards that required compliance with the Japan Electrotechnical Committee (JEC), International Electrotechnical Commission (IEC), or Institute of Electrical and Electronics Engineers (IEEE) standards.

The Investigative Committee also confirmed cases where improper statements were entered in inspection reports. In addition, several designs were found to differ from internal-design guidelines or agreements with customers. Mitsubishi Electric halted shipments of the products in question as soon as the issues were disclosed to company management. Currently, only those products confirmed to have been inspected properly are being shipped. Customers using the products in question have been notified of the situation.

“The root cause of these incidents as well as new measures to prevent any recurrence will be announced as soon as the Investigative Committee issues its final report. Meanwhile, Mitsubishi Electric is continuing to cooperate with the committee to help it complete its investigations as soon as possible,” says in the company’s notice.
