ISO 14487:1997 - "Pulps - Standard water for physical testing" defines requirements for standard water used to prepare pulp suspensions for physical tests where drainability and related properties are sensitive to electrolyte content. Applicable to all kinds of pulp, this International Standard ensures reproducible, comparable test results (for example in laboratory beating and sheet preparation) by specifying how to prepare, test, store and report on water used in pulp testing.
ISO 14487 is essential for laboratories and organizations that perform pulp and paper physical testing where electrolyte concentration affects outcomes. Typical users include:
Using standard water per ISO 14487 promotes consistent results across laboratories, reduces variability caused by dissolved salts, and supports meaningful comparisons in product specification, process control, and research.
ISO 14487 was prepared by ISO/TC 6 (Paper, board and pulps), SC 5 (Test methods and quality specifications for pulp). For integrated test programs, reference ISO pulp and paper test method standards maintained by the same technical committee to ensure complementary procedures and consistent reporting.
