Common explosion-proof certifications

2025-12-15

International certification (preferred for instruments and meters)
1. IECEx certification (International Electrotechnical Commission Explosion proof Certification), abbreviated as IECEx
  - Applicable to: instruments and meters from over 30 countries worldwide (China, European Union, United States, Australia, etc.), such as pressure transmitters, temperature sensors, analytical instruments, etc.
  - Nature: Voluntary international certification with the highest degree of mutual recognition.
  - Standards: IEC 60079-11 (Intrinsic Safety Type "i"), IEC 60079-28 (Gas Detection Instruments), IEC 61241-0 (General Requirements for Dust Environments).
  - Certification body: Laboratories accredited by the International Electrotechnical Commission (such as NEPSI in China and PTB in Germany).
  - Features: With one certification, it can enter multiple national markets, reducing repeated testing; The certificate includes the Ex logo and explosion-proof parameters (such as Ex ia IIC T6 Gb).
2. ATEX certification (EU Explosion proof Directive), abbreviated as ATEX
  - Applies to: instruments and meters in the 27 EU countries and the EEA (such as process control instruments and gas detectors).
  - Nature: Mandatory certification, a necessary condition for entering the EU market.
  - Standards: ATEX 2014/34/EU directive, EN 60079-11 (intrinsic safety type), EN 61241-10 (dust explosion-proof instruments).
  - Certification bodies: EU notified bodies (such as T Ü V in Germany and LCIE in France).
  - Characteristics: The certificate should indicate the equipment category (such as Class II), explosion-proof type (such as d explosion-proof type), gas group (such as IIC), etc., covering mining (Class I) and factory (Class II) equipment.
Core certification in Asia (mainly in China, Japan, and South Korea)
1. China Explosion proof 3C Certification (Instrument and Meter Special), abbreviated as Explosion proof 3C (Instrument and Meter Category)
  - Scope of application: Explosion proof instruments and meters in the Chinese market (such as pressure transmitters, temperature controllers, analytical instruments).
  - Nature: Compulsory certification (implemented from 2020).
