This International Standard defines specific phases and milestones (see Figure 1) 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.
For application in the pharmaceutical or other highly specialized industries, additional
guidelines (for example, Good Automated Manufacturing Practice (GAMP)), definitions and
stipulations should apply in accordance with existing standards, for example, for GMP
Compliance 21 CFR (FDA) and the Standard Operating Procedure of the European Medicines
Agency (SOP/INSP/2003).
