All work areas including the stock and production lines perform a check of
all materials (typically done the last day of the month or the first of the
month) to determine which materials expire in the next 30 days. From
there, if the material cost is less than $200, and it is not needed within
the next 30 days, it is disposed of in accordance with our environmental
policies. If the material is needed for build or it is greater than the
$200 set point, it is submitted to the cognizant materials engineer for
recertification testing. From there, the cognizant materials engineer has
approximately 30 days to have the material tested and determine if it can
be extended. If it tests satisfactory, the material is relabeled with a
shelf life that is half of the original shelf life. This system typically
works very well. We find that most materials tested for recertification
pass. Very seldom do we retest materials for a second extension. We also
do our best to minimize excessive stock to reduce the potential for expired
materials needing recertified.

Hello Technet:
I'm looking for information regarding what other companies do with expired
consumable materials. In the past, when more resources were available, we
had the luxury of having a fully staffed Materials Lab, consisting of both
Engineers and Technicians. One of their functions was to test materials
that were due to expire, in the hopes of extending the shelf life. This
was
a normal course of business and most materials were successfully extended.
Nowadays resources are limited, and we're looking into reducing the shelf
life extension process. One problem is that some materials have a minimum
purchase requirement, much more than can be used up within the
manufacturer's recommended shelf life. Again, what I'm looking for is
what
others do to 1) limit inventory and 2) what is done with expired material.
Please keep in mind that we have to answer to either the DoD or FAA, so
proper control is important.
Thanks,
Jim Marsico
