This part of ISO 10349 specifies a general test method for the determination of pH of solutions of photographic-grade chemicals to within \u00b1 0,1 pH units.<\/p>\n
This method is not intended to monitor the pH of formulated solutions used directly in photographic processing, e.g. developers.<\/p>\n
