ITRI Certification
ITRI Certification for Explosion Protected Products
According to Taiwan’s “Occupational Safety and Health Act” created by the Ministry of Labor, all explosion-protected (Ex) electrical equipment in all areas must comply with applicable safety standards. A registration of safety information must be carried out for Ex products in Taiwan. As part of this registration, the product is checked if it is in accordance with Taiwan’s regulations and standards.
The ITRI (Industrial Technology Research Institute) type approval certificate is required for certain explosion-proof products. The ITRI certification can only be applied for by the manufacturer.
Foreign companies can apply for ITRI certification without appointing a domestic agent.
Product review:
The following documents are required for the first check:
- Applicant’s information
- Information about existing certification(s)
- Basic product information
The electrical products must be certified according to their Ex type and the corresponding standard:

ITRI-Certification Process:
Tests and inspections are part of the ITRI certification approval process in Taiwan.
The ITRI type approval certificate is mandatory for the following products: Ex luminaires, rotating electrical machines, and switch and control panels/gears.
These products must apply for ITRI certification, regardless of existing Ex certificates.
For certain products, it is possible to carry out the ITRI approval process without inspection or testing. Existing certifications and test reports (IECEx, ATEX, etc.) can be used as the basis for ITRI certification.
The above-mentioned standards according to which the products must be certified apply to different Ex-types. If the products already have a current, valid ATEX- or IECEx-Certificate, additional tests may be avoided. Under certain circumstances, IECEx QAR (Quality Assessment Report) or ATEX QAN (Quality Assurance Notification) or other relevant documents that indicate the conformity of the manufacturing and process quality may be recognized.
The ITRI certificate can have different periods of validity depending on the approval procedure. The longest period of validity is 3 years. These are given to manufacturers who already have IECEx certification and can provide test reports that have been issued by foreign Ex-Certification bodies having mutual agreement on test report acceptance with ITRI.
Marking explosion-proof products:
The markings are shown in the following:
The type approval label (show above on the left) indicates the conformity of the explosion-protected products with the established standards (CNS / IEC), while the safety label (shown on the right above) indicates that the products not only conform to the standards and regulations, but that the registration of safety information was carried out in Taiwan. In practice, this means that all explosion-proof products that are shipped to Taiwan must be provided with a safety label. Only products for which ITRI certification is mandatory must also be provided with a type approval label.
