This International Standard describes test methods and requirements for the design of electrical devices to be used on small craft so that they may be oper-ated in an explosive atmosphere without igniting surrounding flammable gases. It does not require explosion-proof or explosion-protected electrical apparatus as defined in IEC 79-0. Ml
This International Standard does not cover ignition protection procedures for products or components that may operate in hydrogen and air mixtutes. Nor does it cover mechanisms of ignition from external sources, such as static electricity, lightning or other factors not related to the apparatus under test.
