Cement put into storage will not be disturbed until it is

issued. Restacking or shifting (to avoid warehouse

pack) exposes the cement to air circulation which

increases the absorption of moisture.

a. Security. Timepieces should be stored in a

room which has adequate security facilities. This room

should be located away from the shock and vibration of

machinery, air conditioned, and free of dust.

b. Temperature.

The controlled temperature

should be maintained near 70 . (+5 .), with an RH

of not more than 50 percent.

c. Unpacking.

When received from the

observatory, the timepieces should be unpacked,

wound, uncorked or unlocked, started, and set to

Greenwich Central Time and given a 10-day run with

daily winding and rating prior to storage. After the 10-

day run, the timepieces should be allowed to run 48

hours more, then stopped and corked or locked, and

stored.
