1、 The meaning of ATEX

ATEX stands for "Atmospheres EXplosibles" in French, meaning "explosive environment". The ATEX directive consists of two EU directives related to equipment used in potentially explosive environments.

ATEX Manufacturers Directive 2014/34/EU: primarily applicable to manufacturers of electrical and mechanical equipment

2、 When was the ATEX directive first adopted?

The ATEX directive was incorporated into the laws of EU member states in March 1996 and became mandatory on July 1, 2003. All products intended for potentially explosive environments that are placed on the market and put into use must comply with the ATEX manufacturer's directives (excluding products excluded from the directives).
3、 What is the definition of "explosive environment" in ATEX?

according to2014/34/EUThe explosive environment defined by the instruction is a mixture of flammable substances

(1) A mixture of flammable substances in the form of gas, steam, mist, or dust

(2) Mixing with air

(3) Under atmospheric conditions

(4) After ignition occurs in the mixture, combustion spreads to all unburned mixtures.

4、 What does ATEX include?

ATEX includes electrical ignition hazards and mechanical ignition hazards. Potential sources of ignition hazards include sparks, arc temperature, sound energy, light radiation, electromagnetic waves, static electricity, stray currents, overheating caused by friction or impact, vibration, pollution, external influences, etc. The equipment is classified as Class I equipment (mining equipment: M1 and M2) and Class II equipment (non mining equipment: Class 1, Class 2, and Class 3)

(1) Class I equipment: equipment used for underground parts of mines and some equipment used for surface facilities of these mines, which can cause explosion hazards due to biogas or flammable dust

(2) Class II equipment: equipment used in other places where danger can occur due to explosive environments. Divided into:

IIA (propane), IIB (ethylene), IIC (hydrogen), II (all gases)

 5、 Marking requirements on ATEX equipment

Including: manufacturer's name and address, CE mark and certification number of the notified unit (i.e. certification body) responsible for the product, ATEX explosion-proof special mark, equipment category and classification, explosive environment type (G gas or D dust), series and type name, manufacturing year and serial number, gas group, temperature level and protection type, ambient temperature, certificate number, other information

 6、 What products are not included in the ATEX directive?

Excluding: household products, medical devices, equipment and protective systems solely caused by explosive substances or unstable chemicals, marine vessels and mobile offshore installations, including personal protective equipment in Directive 89/686/EEC, military equipment, and transportation vehicles through air, road, rail, and water transport networks.
7、 Where can I apply for ATEX certification in China?

Shenzhen Zhongnuo Testing Technology Co., Ltd. has established stable cooperative relationships with many well-known explosion-proof certification agencies at home and abroad, with a professional engineering team and high-quality services. Domestic manufacturers of explosion-proof electrical equipment who need to apply for ATEX certification can handle relevant certification testing at Zhongnuo Testing, which can save a lot of time and cost compared to directly comparing with foreign agencies.
