SIST EN 13754:2009 is the Slovenian adoption of EN 13754:2009, published by SIST for bentonite used in the treatment of water intended for human consumption. It specifies the product characteristics, the requirements for physical and chemical quality, the test methods to check them, and handling information for suppliers, users, and water-treatment operators.

What does SIST EN 13754:2009 specify?

SIST EN 13754:2009 applies to bentonite used for treatment of water intended for human consumption. The standard focuses on how the material is identified, what physical and chemical properties it must meet, how it is tested, and how it is labelled, transported, and stored.

The document is organized into clauses on scope, normative references, terms and definitions, description, physical properties, chemical properties, test methods, and labelling/transport/storage. It also includes an informative annex with general background information.

What are the key requirements of SIST EN 13754:2009?

SIST EN 13754:2009 gives a practical product standard for bentonite, not a process standard. The main requirements tell a buyer or laboratory what to check when receiving, specifying, or testing the material.

Identification and commercial form

Clause 4 identifies the product as bentonite, also known by names such as montmorillonite, and gives its chemical formula, CAS Registry Number, and EINECS Reference. It also states that the product is supplied in powder form and that grades may differ in purity and sodium ion concentration. In practice, this helps users specify the right material and match supplier data to the standard.

Physical properties

Clause 5 describes the expected appearance, particle size distribution, and packed bulk density. The material is described as a white to light brown or green powder, and most of it must be finer than the stated particle size limit. The packed bulk density must fall within the given range. For purchasing and quality control, this means the material can be checked for consistency, handling behavior, and suitability for dosing equipment.

Chemical properties and purity

Clause 6 sets minimum purity requirements and lists the main inorganic components and loss on drying at 105 °C in Table 1. It also notes that other impurities or by-products may be present depending on raw material and process, and that these should be notified when relevant. In practice, this matters because bentonite used in drinking-water treatment must not introduce unwanted contaminants or unexpected process residues.

Test methods

Clause 7 links each property to a test method. Sampling is done using the relevant procedures in EN 12902. Particle size distribution and packed bulk density are determined in accordance with EN 12902, while SiO2 is determined by EN 12902 and Al2O3, CaO, Na2O, and MgO by EN 12485. Mass loss at 105 °C is measured by the water-content method in EN 12902. This gives laboratories a clear test route and helps users compare supplier claims with standard methods.

Labelling, transport, and storage

Clause 8 requires delivery in bags, big bags, or bulk, with clean delivery means to protect purity. It also gives marking requirements, including the product name, trade name and grade, net mass, supplier or manufacturer details, and a conformity statement to EN 13754. The storage guidance says the product is stable but hygroscopic and should be kept dry and away from volatile or odorous materials.

What terms does SIST EN 13754:2009 define?

SIST EN 13754:2009 relies on the terms, definitions, and symbols from EN 12901:1999, and it uses a few key product terms of its own.

• Bentonite - the clay material covered by the standard for water treatment use.
• Montmorillonite - the common mineral name used for bentonite in the document.
• Particle size distribution - the share of material in different size classes, used to control how fine the powder is.
• Bulk density packed - the density of the product when packed, which affects storage and dosing.
• CAS Registry Number - the chemical registry identifier used to identify the substance.
• EINECS Reference - the European inventory reference for the substance.
• Hygroscopic - able to take up moisture from the air, which matters for storage.

Who uses SIST EN 13754:2009?

SIST EN 13754:2009 is used by water-treatment suppliers, plant operators, laboratories, specifiers, and quality managers. It is relevant where bentonite is selected, received, tested, labelled, stored, or documented for use in treating water intended for human consumption.

What changed in SIST EN 13754:2009 from the previous edition?

SIST EN 13754:2009 supersedes EN 13754:2003. The foreword states that the differences from the 2003 edition are editorial and were made to harmonize the text with other standards in the same series.

Which standards are used with SIST EN 13754:2009?

• EN 12901:1999 - provides the terms, definitions, and symbols used for inorganic supporting and filtering materials.
• EN 12902 - provides the test methods used for sampling, particle size distribution, packed bulk density, and mass loss at 105 °C.
• EN 12485 - provides the test methods used for chemical analysis of Al2O3, CaO, Na2O, and MgO.

What does the SIST EN 13754:2009 document contain?

The document contains a product description, physical property requirements, chemical composition requirements, test method references, and rules for labelling, transportation, and storage. It also includes Table 1 for the commercial product composition and Annex A for general information on bentonite.

Annex A covers the origin of bentonite, how it is produced, its physical properties, its function in water treatment, and practical notes on safe handling, first aid, spillage, and fire response. This makes the standard useful not only for acceptance testing but also for day-to-day handling and supplier documentation.
