In addition to this marking from the directive, there are additional items derived from the EN/IEC standards. These indicate the protection concept used, the temperature class and other pertinent data. For example, Ex ib IIC T4 shows intrinsic safety has been applied covering a IIC gas group with a maximum temperature of 135ºC. The full marking from these two examples would thus be: II 2 G Ex ib IIC T4 It would also be necessary to show the EC Type Certificate number (e.g., TRL08ATEX00000X) and the CE mark followed by the number of the Notified Body responsible for the Quality Assurance Notification. The ATEX Declaration of Conformity The ATEX Product Directive has quite specific requirements for the content of the EC Declaration of Conformity. Some of this content is different from other CE marking directives (e.g., the EMC Directive, the Low Voltage Directive). Whilst the exact layout of the ATEX Declaration of Conformity is not prescribed within the directive, the mandatory content is prescribed in Annex X as explained in Table 4. Conclusion The process for ATEX certification has similarities to both the U.S. and IEC systems in that they all involve evaluation of a sample of product and follow-up factory inspections. The specific requirements are outlined in EN published standards, many of which are based on IEC standards. Whilst these standards, for the present, differ from U.S. standards, there are many common areas. If attention is paid to the differences, then compliance with ATEX should pose few problems for U.S. manufacturers.
