Additional Information

Form of Protection Ex ‘e’

Increased Safety Enclosure Type ‘e’ (e.g. IEC 60079-7): Whilst explosive mixtures may enter the equipment, the enclosure is not designed to withstand an internal explosion. Instead, the likelihood of a fault condition, which could result in ignition of explosive mixtures, is significantly reduced by the following measures. The (non-incendive) components used in the equipment shall not produce arcs or sparks or dangerous temperatures in normal working conditions.

Form of Protection Ex ‘de’

Combined Flameproof Enclosure Type ‘d’ & Increased Safety Enclosure Type ‘e’ (e.g. IEC 60079-1 & IEC 60079-7): Primary Flameproof Type ‘d’ Enclosure with Secondary Increased Safety Type ‘e’ Protection, allowing reduced frequency of periodic maintenance and inspection cycle because of the ‘e’ philosophy strategically employed. In the case of Flameproof Type ‘d’ Enclosures having an Increased Safety Type ‘e’ Terminal Chamber, ‘line barriers’ would normally be utilised between the Type ‘d’ and Type ‘e’ compartments creating an indirect cable entry interface.

Form of Protection Ex ‘i’

Intrinsically Safe Enclosure / System Type ‘i’ (e.g. IEC 60079-11): Intrinsically Safe Equipment (Sub grouped into Ex ‘ia’, Ex ‘ib’, and Ex ‘ic’) incorporates circuits which, due to their low spark energy potential, are not capable of igniting an explosive mixture. Ex ‘ib’ equipment is designed to be safe under one fault condition and can be used in Zone 1 explosive atmospheres. Ex ‘ia’ equipment is designed to be safe under two fault conditions and can be used in Zone 0 explosive atmospheres. Ex ‘ic’ equipment is designed to be safe in normal operation, without any faults, and can be used only in Zone 2 explosive atmospheres. The recent introduction of Ex ‘ic’, according to IEC 60079-11, for Zone 2 applications co-incides with the removal of protection method ‘nL’ from IEC 60079-15.

Form of Protection Ex ‘m’

Encapsulation Type ‘m’ (e.g. IEC 60079-5): Encapsulation of arcing and sparking components or equipment in a fashion which ensures that there is no exposure to explosive mixtures which may be present, and the surface temperature is controlled under normal and fault conditions, thus preventing ignition from occurring.

Form of Protection Ex ‘n’

Enclosures with protection Type ‘n’ (e.g. IEC 60079-15): Permitted only in areas where the likelihood of a flammable atmosphere is remote (i.e. Zone 2 Explosive Atmospheres), EPL Gc, Type ‘n’ Equipment was historically divided into a number of different sub-forms.

Form of Protection Ex ‘o’

Oil Immersion with Enclosure Protection Type ‘o’ (e.g. IEC 60079-18): Although not very common, oil immersed equipment, for example early forms of switchgear or transformers, are normally marked Ex 'o' but if the equipment was certified more recently it may also be marked as being Ex 'ob' or Ex 'oc', which includes the EPL code Gb or Gc in this abbreviated marking. The general principal of the form of protection Ex 'o' remains the same.

ATEX Overview

ATEX is the name given to a set of European Directives relating to explosive atmospheres that takes its name from the French translation ‘Atmosphères Explosibles’, and spells out a set of Essential Health & Safety Requirements (EHSR’s) and conformity assessment procedures which when followed should enable the industry to operate safely avoiding accident or incident.
