What is BS EN 12873‑4 about?
BS EN 12873‑4 is the fourth in a series of documents that focus on the influence of migration from materials on water intended for human consumption.
BS EN 12873‑4 describes a test method for laboratory evaluation of possible adverse effects of water treatment membrane elements and modules on drinking water quality. BS EN 12873‑4 is applicable to microfiltration, ultrafiltration, nanofiltration, reverse osmosis and electrodialysis modules for use in the treatment of public water supplies and of water inside buildings.
Note: Such devices can vary in design and operation and hence some modification of the procedures can be required. Evaluation of the efficiency of the membrane filter in removing contaminants from the treated water is not included.
Who is BS EN 12873‑4 for?
BS EN 12873‑4 on Influence of materials on water intended for human consumption is useful for:
- Water supply department
- Water treatment plants
- Hydrologists
- Research and analytical laboratories
Why should you use BS EN 12873‑4?
After having produced drinking water of high quality, it is of vital interest to distribute the water without compromising its quality neither by recontamination nor by microbial regrowth.
BS EN 12873‑4 describes a migration testing procedure that allows water labs and water treatment plants to obtain information not only on the number of chemical compounds but also on the number of growth-supporting compounds leaching into the water.
BS EN 12873‑4 guides you on a test method that is applicable to various other water treatments helping you determine the water treatment modules effect on drinking water quality.
