This standard applies to instruments and electrical parts (including PLC, BAS, DCS, panel-mounted and field instruments) that need to be expanded/rebuilt in new factories and established factories. This standard does not include detailed inspections of other power distribution systems, except those associated with the circuit being inspected (such as the power supply of a motor starter or a four-wire transmitter).
