Introduction to IECEX certification

The IECEx certification system for explosion-proof electrical products refers to the certification of electrical equipment specifically used in industrial sectors such as petroleum, chemical, coal mining, light textile, grain processing, and military industries where explosive gases, vapors, dust, or fibers may accumulate.

Explosion proof electrical products, also known as Ex products, refer to electrical equipment specifically used in industrial sectors such as petroleum, chemical, coal mining, light textile, grain processing, and military industries where explosive gases, vapors, dust, or fibers may accumulate. Early management measures mainly focused on type inspection or type approval of explosion-proof electrical products. In the late 1980s, some industrial countries, For example, Western European countries have successively implemented explosion-proof certification systems for explosion-proof electrical products.

Ex products must obtain explosion-proof certification before they can be used in explosive hazardous areas. The certification system is essential to ensure the safe use of Ex products, but on the other hand, due to the need for repeated explosion-proof inspections and certifications for Ex products entering different countries or regions, it poses many obstacles to the international trade of Ex products. In order to eliminate unnecessary duplicate inspections and certifications of Ex products internationally and promote international trade, an international certification organization for explosion-proof electrical products was established within the scope of the International Electrotechnical Commission in 1992. After several years of preparation, the International Electrotechnical Commission's Explosion proof Electrical Product Certification Organization, abbreviated as IECEx Certification System, was officially established in 1996.

IECEX system member states

So far, there are 24 formal member countries, including Australia, Canada, China, Denmark, Finland, France, Germany, Hungary, Italy, Japan, South Korea, the Netherlands, Norway, New Zealand, Singapore, Romania, Serbia and Montenegro (formerly Yugoslavia), Russia, Slovenia, South Africa, Sweden, Switzerland, the United Kingdom, and the United States. The institution representing China in participating in this international organization is the National Certification and Accreditation Administration (CNCA)

What are the benefits of obtaining an IECEX international certification certificate

(1) The enterprise's products have obtained the IECEx international certification certificate, which proves that the enterprise's production of certified products meets the requirements of relevant IEC standards, and the manufacturer's quality plan meets the requirements of the international explosion-proof certification organization, and the products are produced under the supervision of ExCB.

(2) For products that have obtained the IECEx international certification certificate, enterprises can publish information or copies of the IECEx international certification certificate in advertisements, promotional materials, and product samples. They can also mark the certificate number on the product. If the IECEx certification mark is released, the IECEx certification mark can also be marked on the certified product. Improve the credibility and visibility of enterprises and products, and increase market competitiveness.

(3) If products that have obtained the IECEx international certification are exported, countries that have already received the IECEx international certification, such as Australia and New Zealand, do not need to apply for explosion-proof certification in that country. For member countries that still have differences in standard countries, they can apply for national explosion-proof certification for their products from their certification bodies (ExCB) with the obtained IECEx international certification certificate, inspection report (ExTR), and factory quality system inspection report (QAR), and obtain the certification certificate through a "fast track" to save time and cost. If exporting to non IECEx member countries, it may also receive preferential treatment such as recognition certificates or simplified certification procedures.
