Sec. 1230.20  How should microform records be stored?


    (a) Permanent and unscheduled records. Store permanent and 
unscheduled microform records under the extended term storage conditions 
specified in ISO 18911:2000 and ANSI/PIMA IT9.2-1998, except that the 
relative humidity of the storage area must be a constant 35 percent RH, 
plus or minus 5 percent. Do not store non-silver copies of microforms in 
the same storage area as silver gelatin originals or duplicate copies.
    (b) Temporary records. Store temporary microform records under 
conditions that will ensure their preservation for their full retention 
period. Agencies may consult Life Expectance (LE) guidelines in ANSI/
AIIM standards (see Sec. 1230.3 for availability) for measures that can 
be used to meet retention requirements.
