1 This International Standard gives recommen-dations concerning the storage conditions, storage facilities, handling and inspection for all processed safety photographic films (hereafter referred to as photographic film) in roll, strip, aperture-card or sneet form, regardless of size.
2 This International Standard applies only to safety photographic film (see ISO 543). Nitrate base films are hazardous and unstable and are not covered by this International Standard ）［6］［7］.
3 The storage of photographic paper and photo-graphic piates requires different considerations and these are not covered in this International Standard but are covered in ISO 6051 and ISO 3897, respectively.
4 This International Standard applies to archival and medium-term storage of photographic film as defined in clause 3.
5 This International Standard applies to photo-graphic film records intended as storage copies, which should not be in frequent use. This Inter-national Standard does not apply to "work" or "use" copies (see annex A).
6 This International Standard, while intended for materials that are well processed, should also be of considerable value in prolonging the useful life of photographic film whose processing conditions are unknown, or that have been toned, retouched or have markings with materials of uncertain or unknown stability. It is not intended to predict or assign a useful lifetime to photographic film stored in accordance with the specifications of this International Standard.
