Photography. Photographic-grade chemicals. Test methods – Determination of pH
| Published By | Publication Date | Number of Pages |
| BSI | 2002 | 12 |
This part of ISO 10349 specifies a general test method for the determination of pH of solutions of photographic-grade chemicals to within ± 0,1 pH units.
This method is not intended to monitor the pH of formulated solutions used directly in photographic processing, e.g. developers.
