Abstract The present status of standardisation in "intrinsic safety" approvals is examined in this survey prepared for the U.S. Bureau of Mines, and the supporting data are evaluated. Theoretical considerations on capacitive-resistive circuits, historical review and comparison of standards and rules on intrinsic safety, comparison of minimum igniting curves (inductive, capacitive and resistive circuits), steady-state computer programme for the prediction of hazardous branches in a circuit, experimental system (cadmium disc test apparatus). The survey showed that there are great differences between the test methods, test apparatus, and consequently between the intrinsic safety curves recommended by different countries and organisations.
