3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Explosion-proof type typeofprotection
Specific measures taken to protect electrical equipment from causing ignition of a surrounding explosive atmosphere taken.
3.2
Explosive atmosphere potentialyexplosiveatmosphere
Explosive atmospheres may occur.
3.3
Explosive gas atmospheres explosivegasatmosphere
Under atmospheric conditions, the mixture of air and combustible material gas, vapor or mist formed, the mixture is ignited, the combustion will spread
Environmental entire unburned mixture.
3.4
Flameproof enclosure flameproofenclosure
One kind of type of protection for electrical equipment. Penetrate the shell can withstand any joints or structural gap to the interior of the housing shell can
Combustible mixture in an internal explosion without damage, and does not cause the outer one of a variety of gases or vapors to ignite an explosive atmosphere formed.
3.5
Flameproof joint flameproofjoint
Flameproof enclosure surface corresponding to the different parts fit together (or shell connections) and the flame or the products of combustion from the outside may thus
Reached the interior of the shell portion outside the housing.
