ITRI Certification (TS Certification Taiwan) for Explosion Protected Products
The Occupational Safety and Health Administration in Taiwan has entrusted the Industrial Technology Research Institute (ITRI) as the official agency for type verification of explosion-proof electrical equipment since 2012. To protect consumers, explosion-proof electrical equipment must pass ITRI certification before installation and usage in Taiwan since 2013. Beginning from 2016, explosion-proof products can be imported to Taiwan for sale and installation only after ITRI registration.
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 with regard to its accordance with Taiwan’s regulations and standards.
The ITRI (Industrial Technology Research Institute) type approval certificate (also known as TS Mark Certification Taiwan) can only be applied for by the manufacturer, who also must mark the TS label on the product later.
Foreign companies can apply for ITRI certification without appointing a domestic agent.
ITRI-Certification Process:
Tests and inspections are part of the ITRI certification approval process in Taiwan, during the final stage of which the TS Mark Taiwan must be added to the product.
The ITRI type approval certificate (TS Certificate Taiwan) 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 (TS Certification process) without inspection or testing. Existing certifications and test reports (IECEx, ATEX, etc.) can be used as the basis for TS 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 TS Mark Product Certification for Taiwan 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 with the Taiwan TS Label:
Foreign manufacturers who have successfully applied for ITRI certification are obliged to use the Type Verification Approval Label (on the left; also known as TS Mark) on the product label as well as the certified registration-number. Domestic manufacturers in Taiwan on the other hand use the Safety label on their products (on the right). The marking shows that the product is conform with Taiwan’s regulations and standards.
