(b) For the storage of permanent, long-term temporary, or unscheduled records, use audiovisual storage containers or enclosures made of non-corroding metal, inert plastics, paper products and other safe materials recommended in ISO 18902 and ISO 18911 (both incorporated by reference, see § 1237.3);

(1) Keep all film in cold storage following guidance by the International Organization for Standardization in ISO 18911 (incorporated by reference, see § 1237.3). See also ISO 18920 (incorporated by reference, see § 1237.3).

(a) For picture negatives and motion picture preprints (negatives, masters, and all other copies) of permanent, long-term temporary, or unscheduled records, use polyester base media and process in accordance with industry standards as specified in ISO 18906 (incorporated by reference, see § 1237.3).

(1) Ensure that residual sodium thiosulfate (hypo) on newly processed black-and-white photographic film does not exceed 0.014 grams per square meter.

(2) Process color film in accordance with the manufacturer's recommendations.

(3) If using reversal type processing, require full photographic reversal; i.e., develop, bleach, expose, develop, fix, and wash.

(ii) The sample size must be large enough to yield statistically valid results. To determine the appropriate sample size, use one of the quality sampling methods outlined in ANSI/AIIM TR34 (incorporated by reference, see § 1237.3). Agencies may consult ISO 2859-1:1996 for further guidance (contact NARA's textual research room or NARA's Regulation Comments Desk, see § 1237.3(a), for availability).

(2) Notify NARA, by mail at National Archives and Records Administration; Special Media Records Division (RDS); 8601 Adelphi Road; College Park, MD 20740-6001, or by email at [email protected] (for photographs) or [email protected] (for motion picture film), about the existence of nitrocellulose film materials for a determination of whether they may be destroyed or retained after a copy is made by the agency for transfer to NARA. If NARA appraises nitrate film materials as disposable and the agency wishes to retain them, the agency must follow the standard NFPA 40-2007 (incorporated by reference, see § 1237.3).

(ii) The sample size must be large enough to yield statistically valid results. To determine the appropriate sample size, use one of the quality sampling methods outlined in ANSI/AIIM TR34 (incorporated by reference, see § 1237.3).
