Japan Explosion Proof (JPEx) Certification

Understanding Japan Explosion Proof certification

The Japan Explosion Proof (JPEx) certification is required for electrical equipment intended for use in hazardous locations to launch in the Japanese market.

Japan Explosion Proof (JPEx) certification is a mandatory requirement for electrical equipment intended for use in explosive atmospheres in Japan. This certification aligns with international standards for electrical equipment intended to be used in hazardous locations, such as the International Electrotechnical Commission System for Certification to Standards (IECEx) and the European Union’s ATEX directive for devices intended for use in explosive atmospheres. (ATEX comes from the description of the hazardous materials, “devices intended for use in explosive atmospheres,” or as written in French: “appareils destinés à être utilisés en ATmosphères EXplosives.”) The certification process involves rigorous testing and evaluation to meet the specific safety requirements set by Japanese regulations.

Why JPEx certification is essential

Market access

JPEx certification is a prerequisite for selling explosion-proof equipment in Japan. Without it, manufacturers cannot legally market their products in hazardous locations within the country.

Enhancing safety

The certification communicates that equipment meet safety standards to operate in environments with explosive gases, dust or fibers, thereby helping to reduce the risk of accidents and enhance workplace safety.

Obtaining JPEx certification demonstrates a commitment to safety and quality, giving manufacturers a competitive edge in the market.
