Overview
EN 12911:2013 is the CEN (European) product standard for manganese greensand used in the treatment of water intended for human consumption. The standard defines identification, physical and chemical characteristics, required performance parameters, and the corresponding test methods for manganese greensand. It also provides guidance on labelling, transportation, storage and practical use information relevant to drinking-water treatment systems. EN 12911:2013 supersedes EN 12911:2006 and was approved by CEN in 2013.
Key topics and technical requirements
The standard specifies what suppliers, laboratories and users must test and declare. Key technical topics include:
- Product identity
- Chemical nature: manganese oxide coated zeolite (glauconite). Synonyms: manganese greensand, manganese zeolite, ferro-sand, greensand.
- CAS references provided for glauconite and manganese oxide.
- Physical requirements
- Appearance: dry, free‑flowing, black, manganese dioxide-coated granules.
- Particle size distribution: effective size (d10) 0.30–0.35 mm ± 0.03 mm; uniformity coefficient U < 1.6; minimum size (d1) ≥ 0.25 mm; maximum particle size ≤ 1.25 mm. Alternative sizing by mass fractions with oversize/undersize limits 5%.
- Bulk density (loose):≥ 1 300 kg/m³.
- Chemical and performance parameters
- Manganese oxides (as Mn):0.2–0.8% (mass fraction).
- Mass loss at 150 °C: max 6%; Ignition loss at 650 °C: max 8%.
- Oxidation capacity (regenerated form):≥ 0.7 g Mn per litre of packed product.
- Test and quality control
- Sampling and analytical methods referenced (notably EN 12902 for particle and density tests and ISO/AOAC methods for manganese determination).
- Safety, labelling and storage
- Clauses cover means of delivery, EU labelling requirements, transport marking and recommended storage conditions and incompatibilities.
Applications and users
EN 12911:2013 is intended for organizations involved in drinking-water treatment and supply, including:
- Water utilities and municipal treatment plants
- Filter media manufacturers and suppliers
- Consulting and design engineers specifying filtration media
- Laboratories performing conformity testing and quality control
- Regulatory authorities and procurement officers assessing product suitability
Practical use: the standard helps specify, test and verify manganese greensand performance and conformity when selecting granular media for treatment systems handling water intended for human consumption.
