This part of IEC 60079 provides guidance for the application of electrical resistance traceheating systems in areas where explosive atmospheres may be present, with the exclusion ofthose classified as requiring EPL Ga/Da (traditional relationship to Zone 0 and Zone 20respectively). This standard also provides guidance for explosive atmospheres incorporatingthe Division method of area classification that may be applied by some users of this standard.NOTE Information on the Division method is given in NFPA 70 and CSA C22.1.It provides recommendations for the design, installation, maintenance and repair of traceheating systems including associated control and monitoring equipment. It does not coverdevices that operate by induction heating, skin effect heating or direct pipeline heating, northose intended for stress relieving.
