"Extending" Life
Major maintenance and other activities to ensure that an asset is not retired (or renewed) before it has reached the end of its intended design life (or service life) and goes beyond the normal life threshold.

Does painting allow an asset to "reach" its normal/design life or does it "extend "its life (the underlying component).

The lives of some assets cannot be extended beyond a certain point, either due to legislative timetables or other factors. For example: the life cannot be extended on a smoke detector or a fire extinguisher.


Actions
Activities to help extend the life of an asset include the following:
Mechanisms to monitor that life is being extended:

Candidate Assets
Listed below are some of the key factors to determine whether the life of an asset has been extended or can be extended:
  • The end of life of the asset must be clearly defined through observed life tables (OLTs).
  • Wide dispersion on the survivor curve.
  • Obsolescence is not a factor
  • Bounded assets can only reach life and not be extended due to statutory requirements.
  • Age-based replacement policy
