Testing and Certification under the IECEx Certified Equipment Scheme:

IEC (International Electrotechnical Commission) has been operating a global certification system called "IEC System for Certification to Standards relating to Equipment for Use in Explosive Atmospheres"(hereinafter referred to as "IECEx"). (For more details see the IECEx website)

Under the framework of the IECEx, the most widely accepted is "Equipment Certification Scheme covering equipment for use in explosive atmospheres", which provides manufacturers of such Ex-equipment with "IECEx Certificates of Conformity (IECExCoCs)".

Applicable Standards:

TIIS has been accepted by the IECEx as competent to the following standards, and authorized to issue IECEx Test Reports (ExTRs), IECEx Quality Assessment Reports (QARs) and IECExCoCs.
An IECEx certificate may be issued to the current IEC Standard or one edition prior as shown below.

National Differences:

To enable harmonisation on a global scale, the IEC requires the identification of national differences of standards and regulations from IEC Standards.
National Differences of Japan are shown in the following document for your reference.

Application Guide:

Application Guide for IECEx Certificate of Conformity(IECExCoC), Test Report(ExTR) and Quality Assessment Report(QAR) under the framework of Certified Equipment Scheme of the IECEx System to TIIS

Certification Cost:

Cost and time for certification are estimated based on the time required and unit value of each items such as assessment for documents, control of samples, type tests, witness testing/off-site testing (if neceesary), preparation for report, review for certification, processing of CoC and other reports, etc.
