Service, maintenance
Definition of terms in accordance with IEC 60079-17:
Maintenance and service: A combination of all tasks carried out to maintain an
object in or return it to a condition which corresponds to the requirements of the
respective specifications and ensures that the required functions can be
performed.
Inspection: Careful examination of the object with the goal of making a reliable
statement on the condition of the object. Inspection is carried out without
disassembly or, if necessary, with partial disassembly, supplemented by
procedures such as taking measurements.
Visual inspection: An inspection which determines visible faults, such as missing
screws, without the use of access equipment or tools.
Close-up inspection: An inspection which, in addition to the faults determined by
visual inspection, also determines faults, such as loose screws, that can only be
found by using access equipment, e.g. steps (if required) and tools. For close
inspections, the housing usually does not need to be opened and the equipment
can usually stay energized.
Detailed inspection: An inspection which, in addition to the aspects determined by
close inspection, determines faults, such as loose connections, that can only be
found by opening housings and/or using tools and testing equipment, if required.
