GLOBAL UNDERSTANDING AND EXPERTISE
Appleton electrical products help protect re nery production in India, ensure pipeline  ow in South Africa, and maintain deep sea drilling
operations in the Gulf of Mexico. Our worldwide presence demands mastery of the International Electrotechnical Commission (IEC), ATEX Directive
and the North American (NEC/CEC) rules and a full product line for every application throughout hazardous locations.
IEC, ATEX and NEC/CEC rules each identify the amount of exposure, destructive force and ignition temperature of the gas, vapor or dust.
However, the separate regulations differ in their nomenclature and sub-category tracking. To assist in out tting and application, the following
pages show the ratings and categories of each regulation body and reference points.
