7925G-EX Certifications

The Cisco Unified Wireless IP Phone 7925G-EX has both Atmoshpheres Explosibles (ATEX) Zone 2/Class 22 and Canadian
Standards Association (CSA) Class1/Division II certifications in order to allow it to be used in hazardous and explosive
environments.
Atmospheres Explosibles (ATEX) Zone 2/Class 22 Certification
Organizations in the European Union must follow the ATEX directives to protect employees from explosion risk in areas with
an explosive atmosphere.
ATEX 95 equipment directive 94/9/EC
•
Equipment and protective systems intended for use in potentially explosive atmospheres.
ATEX 137 workplace directive 99/92/EC
•
Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive
atmospheres.
Areas classified into zones (0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust) must be protected from effective sources of
ignition. Equipment and protective systems intended to be used in zoned areas must meet the requirements of the directive.
Zone 0 and 20 require Category 1 marked equipment, zone 1 and 21 required Category 2 marked equipment and zone 2 and 22
required Category 3 marked equipment. Zone 0 and 20 are the zones with the highest risk of an explosive atmosphere being
present.
Certification ensures that the equipment is fit for its intended purpose and that adequate information is supplied with it to ensure
that it can be used safely.
Canadian Standards Association (CSA) Class I/Division II Certification
Laws and regulations in most municipalities, states, and provinces in North America require certain products to be tested to a
specific standard or group of standards when they are to be deemed intrinsically safe when used in an explosive environment.
In North America, hazardous locations have traditionally been defined by the following combination of Class and Division:
