Typical Problems Encounted During Ex m and Ex q Inspection
Published: . Read Time: 2 mins.
Principle -
Ex m - Parts that could ignite an explosive atmosphere by means of sparks or heat are potted so as to prevent ignition of the explosive atmosphere. This is achieved by encapsulating the components in a compound resistant to physical - especially electrical, thermal and
mechanical - and chemical influences.
Ex q - By filling the enclosure with a finely grained powder, an arc within the enclosure is unable, with correct use, to ignite the
explosive atmosphere outside. There must be no risk of ignition by flames, nor by increased temperatures at the surface of the enclosure.
