MIL-STD-1622B(SH)

5.3.6  Dry, reassemble and package.  Drying, reassembling, and packaging shall be accomplished in a clean area as follows:

(a)Components shall be dried until no moisture is visible using any method that does not result in loss of cleanliness.  Ovens, vacuum ovens, dryers, heat guns, and dry air or nitrogen have been successfully used.  Appropriate precautions shall be taken to prevent damaging components and software from excessive heat.  For components with inaccessible areas, drying to -20o  dew point is acceptable.

(b)During reassembly, use lubricants as specified in 4.7. (c)Components shall be packaged as specified in 5.16.1.

5.4  Flask cleaning.

5.4.1  Applicability.  Steel flasks in the boundaries defined in 1.2 shall be inspected, preserved, and cleaned as specified in NAVSEA S9086-SY-

STM-010/CH-551.  The flask cleaning process specified in Table III may be used in place of those specified in NAVSEA S9086-SY-STM-010/CH-551 for uncoated flasks or phosphate coated flasks used in general or critical applications.

Do not use NOC or TSP on painted flasks as these alkaline cleaners will damage the coating.  Use of the following flask cleaning process requires local engineering approval.

5.4.2  Material and equipment.

(a)A supply of rinse water and associated equipment for rinsing flasks.

(b)For general applications, a supply of NOC or TSP as specified in

4.2, or other low foaming cleaner selected as specified in 4.3.

For critical applications, a supply of NOC or TSP as specified in

4.2.

(c)A supply of air or nitrogen.

(d)Equipment to perform visual inspections and clean the flask.

(e)Equipment to perform the applicable analyses of 5.14.  This

includes clean containers of no less than twice the sample volume

to obtain the required samples.

(f)A dew point indicator equal to the Ondyne Series 1400 Dewpoint

Indicator or the MCM Dewluxe Model hygrometer capable of detecting a dew point of -20oF (420 ppm H2O).
