The aim of ATEX Directive is to prevent the damage to proerty and to protect the life of people.
As of July 2003, organizations in the EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere.
There are two ATEX directives (one for the manufacturer and one for the user of the equipment):
•The equipment directive 2014/34/EU, equipment and protective systems intended for use in potentially explosive atmospheres;
• The ATEX 137 workplace directive 99/92/EC, Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.
The objective of the IECEx Scheme
The objective of the IECEx Scheme (International Trade of Electrical Equipment used in Explosive Atmospheres) is to facilitate international trade in electrical equipment intended for use in potentially explosive atmospheres by eliminating the need for multiple national certification. The IECEx Scheme provides a means for manufacturers to obtain Certificates of Conformity that will be accepted at national level in all participating countries. A Certificate of Conformity may be obtained from any certification body accepted into the scheme. The objective of the IECEx Scheme is world-wide acceptance of one standard, one certificate, and one mark.
The Ex scheme applies to manufacturers of:
• Electrical apparatus for explosive gas atmospheres
• Electrical apparatus for the detecting and measurement of flammable gases
• Electrical products such as switches, outlets and outlet boxes, circuit breakers, electric motors, and lighting used in hazardous environments
The obvious benefits of the IECEx scheme are:
• Reduced testing and certification costs to manufacturer
• Reduced time to market
• International confidence in the product assessment process • One international database listing
• Maintaining international confidence in equipment and services covered by iecex certification
