Scope

1   Scope 1.1    This International Standard describes methods for evaluating the effectiveness of chemical conver­sion treatments intended to increase the resistance of wet-processed silver images to oxidation. The treatment may be applied as part of the original pro­cessing, or it may be a post-processing treatment. This International Standard does not recommend general or specific treatments for silver images. Likewise, treatment temperature, times and replenishment rates are out­side the scope of this International Standard. Factors to be considered in a stabilizing treatment are discussed in informative annex B. Two test methods are described: the "dichromate bleach test" and the "hydro­gen peroxide incubation test" (see [7] in the bibliography). The significance of each is discussed in informative annex C.
