IEC 62337:2006 defines specific phases and milestones in the commissioning of electrical, instrumentation and control systems in the process industry. By way of example, it describes activities following the "completion-of-erection" milestone of the project and prior to the "acceptance-of-the-plant" phase by the owner. Such activities need to be adapted for each type of process/plant concerned. This bilingual version (2013-05) corresponds to the monolingual English version, published in 2006-11. It cancels and replaces IEC/PAS 62337 published in 2002. This first edition constitutes a technical revision.
