| Zusammenfassung | Due to the miniaturization of electronic components and circuits, as a result of the everadvancing innovative optimization process, manufacturers of flameproof enclosures have the necessity to adapt their flameproof enclosures for smaller internal free volumes. The standard IEC 60079-1 for the type of protection Flameproof Enclosure "d" defines several internal free volume groups that go along with constructive requirements for the different types of joints. Nevertheless, the use of flanged joints for group IIC devices is very limited. Under the occurrence of acetylene containing atmospheres, they are only permitted if the internal free volume is ≤ 500 cm³ However, the requirements are not suitable for enclosures with small internal free volumes. This paper shows, after a first testing process, the minimum requirements for flameproof flanged joints of a small-internal free volume enclosure with a specific internal geometry. Here tests for non-transmission of an internal ignition and reference pressure tests with an enclosure with approximately 0.09 cm³ internal free volume are presented. In the end, a deeper understanding of the flame transmission in flanged joints of Group IIC in flameproof enclosed equipment will be achieved. |
