This standard provides a laboratory test method for determining whether a metallic or nonmetallic con-struction material in contact with either a black-and-white or color processing solution causes an adverseeffect on sensitized photographic materials. Construction materials such as metals, alloys, plastics, elas-tomers, paints, and similar materials may be tested by this method.This standard is not intended for determining the physical properties or the durability of construction mate-rials used in photographic processing equipment.This standard does not necessarily ensure that processed film or prints, or both, will be of "archival" qual-ity. Effects of processing equipment construction materials on long-term stability of photographic materialscan be determined only by suitable accelerated aging studies.
