Storage Guidelines (from IB 523-0768039 Appendix C)
Following storage conditions:
- Temperature between 60F and 75F
- Humidity between 30% and 50%
- Storage in original shipping containers whenever possible. If this is not possible, then stored in the original bag (or equivalent ESD protective bag), on a shelf covered with a 3/4 inch compressible, conductive foam pad.
- In an area free of dust, dirt, lint or chemical fumes
- Instruments with CRT displays must be stored at least two feet away from highly magnetic devices (magnetrons).
Definitions and Conditions
Shelf life refers to the period of time that an LRU can remain in storage and be expected to perform to specifications when required. The shelf life recommendations assume a controlled environment with regard to humidity, contaminants, and temperature cycling/extremes. Collins recommends the following guidelines. Storage in the original packaging is also recommended.
- Humidity less than 60%
- Temperature 20�+/-10�C
- Contaminants noncorrosive
- Contaminants no excess particulates
Observing the shelf life schedule and environmental controls ensures a high probability that the unit will be operational when required for use. After the recommended time has elapsed, the unit should be recertified per the Component Maintenance Manual (CMM).
Failure to retest the unit at the end of the period decreases the probability that the unit will function according to specifications when required for service.
