Additional Information

The Use of Multiple Adaptors in a Single Entry for Ex Equipment

The IEC 60079-1 standard allows the use of threaded adaptors and reducers for direct entry into Flameproof type ‘d’ enclosures. In future, the female connection threads of the adaptors and/or reducers will be limited to metric or NPT only. When using thread adaptors and reducers or reducer bushings, only one is permitted for any single cable entry of Flameproof type ‘d’ (Ex d) equipment.

Sheath Material Mechanical Properties

When specifying, selecting, evaluating or assessing cables, the type of material used for the sheathing should always be taken into account. Some of the standards mentioned above have very specific requirements for the tensile strength of cable sheathing, and in some cases these may be less than that required by IEC 60079-14.
