[labnetwork] Equipment Expected Lifetime

[Colwill, Bryant C.]

Hello All,

Long time stalker, first time talker.
As the title suggests, I'd like to hear some collective thoughts and 
experiences on expected equipment lifetimes.
Obviously very dependent on what it is, what it does, who made it, who 
uses it, etc., etc. but in a very general sense when is the average 
piece of equipment (if there is such a thing) on borrowed time?  I'm 
sure we all have some decades old machines and that replacing them 
solely for modernization's sake would be considered financial 
malfeasance.  However, under a more manufacturing mindset a strategy for 
planned obsolescence is not a bad idea.

To hopefully facilitate some replies/debate/conversation, here's my two 
cents:

Metrology Equipment --> 5-10 years
Processing Equipment --> 12-17 years

Also took a quick age survey of our ~50 pieces of equipment and found 
the following distribution:



If the pie chart graphic isn't visible:  0 tools < 5years, 15 tools 
between 5 and 10 years, 17 tools between 5 and 10 years, 18 tools < 20 years

Be well,
Bryant
