What is BS EN 12873-3 - Ion exchange resin testing about?
Ion exchange resins are used for water treatment. BS EN 12873-3 specifies a procedure to determine the migration of substances from ion exchange, in water intended for human consumption.
Resins comprise synthetic organic macromolecular materials. BS EN 12873-3 is applicable to resins of the following types:
- Ion exchange resins: used to modify the composition of water (e.g. softening by removal of calcium ions). They can be in either an anionic or cationic state
- Adsorbent resins: used to lower the concentration of undesirable substances (usually organic pollutants) from water. They are used in a neutral state
- Hybrid adsorbers: Organic polymer based ion exchange resin or adsorbent resin with incorporated inorganic (e.g. iron hydroxide) or second organic phase. Used to lower the concentration of undesirable substances (specific inorganic or organic pollutants) from water. They can be in either an anionic, cationic or neutral state
Who is BS EN 12873-3 - Ion exchange resin testing for?
BS EN 12873-3 on ion exchange resin testing is useful for:
- Water distribution authorities
- Health and safety inspectors
- Regulatory authorities
- Water treatment plants
- Residential, commercial and industrial site inspectors
- Government bodies
Why should you use BS EN 12873-3 - Ion exchange resin testing?
The first step in mitigating a risk is to identify and quantify it. BS EN 12873-3 provides guidelines to monitor the effects of ion exchange on the resin. This way you can monitor the quality of water supplied to users. BS EN 12873-3 helps you to ensure sufficient purity level for reagents.
BS EN 12873-3 also helps you to detect contamination and identify its source by providing guidelines for using procedural blanks and laboratory blanks.
What’s changed since the last update?
BS EN 12873-3-2019 supersedes BS EN 12873-3:2006, which has been withdrawn. BS EN 12873-3-2019 updates include:
- Introduction of a second sampling method
- Specification of a method of control for the test device
