kSIST FprEN 882:2026 is a draft standard for sodium aluminate used in the treatment of water intended for human consumption. It specifies how the product is identified, what purity limits apply, how it is tested, and what information is needed for delivery, labelling, storage and safe handling. It is written for manufacturers, suppliers, laboratories and water-treatment users who need a common product specification.
What does kSIST FprEN 882:2026 specify?
kSIST FprEN 882:2026 applies to sodium aluminate used for treating water intended for human consumption. It describes the product, sets purity criteria, points to the analytical methods to use, and gives guidance on use in water treatment.
The document is organized into seven clauses and two annexes. Clause 4 identifies and describes the material, Clause 5 sets purity criteria, Clause 6 covers test methods, and Clause 7 covers labelling, transport and storage. Annex A gives general information on sodium aluminate use, and Annex B gives safety rules.
| Annex | What it covers |
|---|---|
| Annex A | General information on sodium aluminate, including origin, manufacture, quality, use, dose, application and removal of excess product |
| Annex B | General rules relating to safety, including safe handling and emergency procedures |
The introduction also notes that conformity with the document does not by itself mean the product is accepted in every EU or EFTA Member State. In practice, users still need to check the national rules that apply where the product will be used.
What are the key requirements of kSIST FprEN 882:2026?
kSIST FprEN 882:2026 is mainly a product specification. The most important requirements are the identification of the chemical, the purity limits, the test methods, and the controls for delivery, labelling and storage.
Product identification and form
Clause 4 identifies sodium aluminate by chemical names, its common name, formula information, and registry numbers. It also says the product is supplied as solids or solutions. For a buyer or laboratory, this helps make sure the product ordered, received and tested is the correct chemical and not another aluminium compound.
Clause 4 also describes the physical form: solids may be powder or granules, while solutions may be colourless to yellow liquid. The document gives physical property data such as density, solubility, viscosity and melting or crystallization behavior. These details matter because they affect pumping, dilution, storage and handling on site.
Purity criteria and impurity control
Clause 5 sets minimum purity requirements for sodium aluminate used in water treatment. The active matter content in the commercial product, expressed as aluminium, must stay within the tolerance stated against the manufacturer's declared value. That matters for dose control, because the treatment effect depends on the actual aluminium content.
Clause 5 also limits impurities and main by-products. Table 2 sets limits for iron and insoluble matter in solid product. Table 3 sets limits for key chemical parameters, including arsenic, cadmium, chromium, mercury, nickel, lead, antimony and selenium, and groups products into three parameter types. In practice, this is the part users check when they need to match a product grade to raw water quality and treated-water objectives.
The annex adds a practical warning: the selected grade can affect trace metals in the treated water, so the product grade should be chosen with the raw water, dose, process conditions and local water-quality targets in mind.
Test methods
Clause 6 is simple but important: sampling and analysis must use the relevant methods in EN 1302. That means the product is not tested with an arbitrary in-house method if conformity is being checked. For quality control and acceptance testing, users need the EN 1302 methods for aluminium-based coagulants.
Delivery, labelling, transport and storage
Clause 7 controls how the product is delivered and stored. Solids should be delivered in suitable packages or lined bulk trucks, and liquid product should be delivered in corrosion-resistant tankers. Delivery equipment must not have been used previously for another product unless it has been cleaned and prepared. This helps prevent contamination that could affect purity or safety.
Clause 7 also points to EU labelling requirements and transport rules. The document associates the product with corrosive hazard labelling and gives transport entries for solid and solution forms. For logistics teams, this is the section that drives packaging, shipping documents, warehouse handling and hazard communication.
Storage guidance is practical as well. Solution tanks should be made of corrosion-resistant material, and external tanks may need protection against freezing or excessive viscosity increase. The product must also be kept away from incompatible substances such as acids and several metals and metal salts. This matters because sodium aluminate is strongly alkaline and can react aggressively with some materials.
Use and safety
Annex A describes sodium aluminate as a coagulant and flocculant. It explains how it is typically diluted before use, gives guidance on usual dosing, describes how it is applied, and lists expected secondary effects such as increased pH and alkalinity. It also explains how excess product should be removed during treatment so that aluminium levels are reduced in the finished water.
Annex B sets the safety approach. The supplier must provide current safety instructions, and the annex gives procedures for accidental contact, spillage and fire. In practical terms, it tells operators how to respond quickly if the product is spilled, inhaled, ingested or splashed.
Who uses kSIST FprEN 882:2026?
kSIST FprEN 882:2026 is used by people who specify, supply, receive, test and apply sodium aluminate in drinking-water treatment. Typical users include:
- water utility and treatment-plant operators, for dosing and process control
- procurement and quality managers, for product specification and supplier checks
- manufacturers and suppliers, for product declaration, labelling and transport
- laboratory staff, for sampling and analysis against EN 1302
- transport and warehouse teams, for packaging, incompatibility control and storage conditions
The standard is especially relevant where sodium aluminate is used as a coagulant or flocculant and where the operator must manage pH, alkalinity and trace-metal carryover.
What changed in kSIST FprEN 882:2026 from the previous edition?
kSIST FprEN 882:2026 supersedes EN 882:2016. The change stated in the document is an update of the information related to the Drinking Water Directive.
Which standards are used with kSIST FprEN 882:2026?
kSIST FprEN 882:2026 names EN 1302 as its normative reference. EN 1302 provides the sampling and analytical methods used for this product family.
The bibliography also points to Directive (EU) 2020/2184 and Regulation (EC) No 1272/2008. The directive is used as the drinking-water policy reference in the annexed trace-metal discussion, and the regulation supports the labelling approach for classification and packaging.
What does the kSIST FprEN 882:2026 document contain?
kSIST FprEN 882:2026 contains identification data, physical-property data, purity requirements, analytical references, transport and storage guidance, and safety information. It also includes a viscosity table and annexed tables showing the effect of product grade on trace metals in treated water.
The document gives practical guidance on dilution, dosing, application by metering pump, and removal of excess aluminium during treatment. It also gives emergency actions for accidents, spillages and fire, which makes it useful not only for purchasing and specification work but also for plant operation and operator training.
