Area classificationClassement de zoneExplosionsgefährdeter Bereich

level of protection assigned to a piece of equipment based on its risk of becoming a source of ignition in an explosive gas atmosphere, an explosive dust atmosphere or an explosive atmosphere that may exist in a coal mine

classification system of electrical apparatus, based on its maximum surface temperature, related to the specific explosive atmosphere for which it is intended to be used

classification of a hazardous area based on its location

name of the hazardous area

plain text characterizing the hazardous area

element of a hazardous area classification system indicating the likelihood of the existence of a classified hazard

element of a hazardous area classification system in the USA and Canada indicating the likelihood of the existence of a classified hazard

element of a North American hazardous area classification system indicating the type of atmosphere present at the instrument installation point

classification of dangerous gaseous substances based on their ability to cause an explosion

classification of dangerous dust or fibers based on their ability to cause an explosion

indication of the presence of an hazardous atmosphere where no zone definition exists

lowest temperature of a hot inner wall of a furnace at which ignition occurs in a dust cloud in air contained therein

highest temperature which is attained in service under the most adverse conditions (but within the specified tolerances) by any part of surface of an electrical apparatus, which would be able to produce an ignition of the surrounding explosive atmosphere

type of protection, which is preferred for the use in the hazardous location

code or standard on which the explosion protection measures are to be based
