Résumé

1.1 This International Standard specifies dark storage conditions, storage facilities, and handling and inspecting

procedures for processed photographic plates having integral photographic layers and intended for record

purposes.

1.2 This International Standard is applicable to black-and-white, silver-image, gelatin, processed photographic

plates as defined in 3.7.7. It is also applicable to medium-term and extended-term storage conditions as defined in

3.6 and 3.2, respectively.

No specific distinction is made, other than the degree of care, between photographic plates for medium-term or

extended-term storage. Recommendations for plate storage relate to materials, methods, conditions, and forms of

protection applicable specifically to plates defined in 1.1. However, these storage recommendations may also be

applied to lacquered and opaque plates, to black-and-white plates altered by dyes or toners, colour plates and

other historic photographic plates defined in 3.7.2 to 3.7.8.

1.3 It is not intended to predict or assign a useful lifetime to processed photographic plates stored in accordance

with the specifications of this International Standard.

1.4 Recommendations for storage of photographic films are given in ISO 18911 and for storage of processed

photographic reflection print material in ISO 18920.

Although there is some variation in recommended storage conditions among these types of photographic materials,

recommended temperature and relative humidity ranges do overlap. If all three types of photographic materials are

found in one collection or within one storage area, the temperature and relative humidity should be chosen so that

all materials are stored within their recommended ranges.
