IEC 60079-19:20 10对设计用于爆炸性环境的设备的修理、大修、回收和改造给出了主要是技术性质的说明；它不适用于维护，除非维修和大修不能与维护分开，也不就重新安装设备时可能需要更新的电缆进入系统提供建议。与上一版相比，重大技术变化如下: -列入具体的第一组要求； -纳入离岸要求。

IEC 60079-19:2010 gives instructions, principally of a technical nature, on the repair, overhaul, reclamation and modification of equipment designed for use in explosive atmospheres; it is not applicable to maintenance, other than when repair and overhaul cannot be disassociated from maintenance, neither does it give advice on cable entry systems which may require a renewal when the equipment is re-installed. The significant technical changes with respect to the previous edition are:
- inclusion of specific Group I requirements;
- inclusion of offshore requirements.
