Archivability check
The archivability of the processed film is evaluated by measuring the residual thiosulphate in the emulsion layers. The Structurix Thio-Test provides the means for performing the control of fixing and washing as described in EN 584-2 and ISO 11699-2.
The Structurix Thio-Test kit consists of:
• the Thio-Test Color Stepwedge with four steps, which relate to the archivability expressed in number of years
• one dropper bottle of Thio-Test reagent, of 35 ml (about 1,000 drops)
The Structurix Thio-Test also correlates perfectly with other international standards (ISO/ ANSI) for determining the archival quality of industrial X-ray film. It is a quick and simple method to determine the “life expectancy” of processed films and warns of poorly fixed and/or washed films.
