Transition from DS to TS
• Effective immediately or transition period?• What about existing CoCs to DS?
- Will they be permitted to remain to DS?- Will they be permitted to be revised to DS?- Will they be required to upgrade to TS?
• What about new CoCs in process during transition?- Will they be permitted to be issued to DS?
• IECEx transition can identify any issues with TS

Identifying an Equipment assembly
TS defines Equipment assembly as:pre-manufactured combination of Ex Equipment, together with other parts as necessary, that are electrically or mechanically interconnected that are pre-assembled prior to being placed into service at the end-user site, and that can be disassembled and then re-assembled at the end-user site

Identifying an Eqpt. assembly (cont.)
TS Scope exclusions include:• Equipment entirely covered by other types of
protection• IEC 60079-13, IEC TR 60079-16• Installation & area classification at end-user site• Group I applications
