Update on standards

A2S products meet and exceed the requirements of many global standards, including UL, cUL, IECEx, ATEX, FM, VdS, DNV, INMETRO, CU TR and MED certifications.

ATEX regulations

ATEX (ATmosphères EXplosives) regulations apply in France and in all countries of the European Union. They are the result of two European directives on equipment and on worker safety. They set "essential requirements" for manufacturers of electrical equipment used in explosive atmospheres and impose strict product marking.

To comply with these regulations, suppliers of products intended to be installed in hazardous areas must issue a declaration of conformity for each order.

The international system

IECEx is an international system that certifies the conformity of equipment used in explosive atmospheres. It follows standards issued by the International Electrotechnical Commission and provides manufacturers with a certification of conformity. This is based on evaluation tests and monitoring of the manufacturer's quality assurance. This system has been adopted or is being adopted by countries around the world.

Other standards include the American and Canadian UL and CSA standards, the EurAsian Conformity Mark, used in Russia, Kazakhstan, Belarus and Armenia, INMETRO, in force in Brazil, and PCEC for China.
