Standards and Guidelines
Boilers
Direct Heating
Gas Controls
  • International Electrotechnical Commission Technical Committee 72. IEC/TC 72 was initially established to fill the needs for international safety standards for automatic electrical controls for use in household appliances and similar equipment. The scope was recently expanded to include industrial applications. The USNC TAG was established to harmonize U.S. safety philosophies and practices within IEC/TC 72 with those of the European Union and Asia Pacific regions.
  • International Organization for Standardization, ISO/TC 161. ISO/TC 161 was established to develop a set of International Standards in the field of control and protective devices for gas and oil burners and appliances using as a bases existing local or regional standards.
