Calibration Merry Go Round - Torque Wrenches and Testers

[dgriffith]

Wow, learning alot here. Problem is we have up to 600 ft-lb and they are at 5 different locations. I believe I'm going to have to bite the bullet and calibrate every quarter. Does anyone know of any labs that do in-house calibrations on torque wrenches?

Not sure what you mean here. In-house usually means the owning organization also calibrates their own tools.
An external vendor could come to your 'doorstep' at some interval to do them in situ (on location).
Six-hundred lbf.-ft. is no problem. Having them in 5 locations--does that mean in the same building, same campus, same city? Five torque testers is 10 grand, plus calibration every year. What is the cost of fastener failure, though?

Noooooo

5 locations = 5 torque analyzers. If you have done the torque process analysis by "family", then this is sufficient and you can do the "check before use" or something, weekly/monthly until you have data to support making it less frequent. The analyzers can be done by having a lab-in-a-van come to you...

We own tools, employees own tools. We do our in-house calibrations but are on the look-out for a lab in a van so to speak. Torque Testers go to an outside lab.
5 different locaitons \ cities and buildings.

For clarification: You are looking to have the torque testers done by the lab-in-a-van?
