1 Scope This European Standard is applicable to poly (diallyldimethylammonium chloride) used for treatment of water intended for human consumption. It describes the characteristics of poly (diallyldimethylammonium chloride) and specifies the requirements and the corresponding test methods for poly (diallyldimethylammonium chloride). It gives information on its use in water treatment. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 3696, Water for analytical laboratory use — Specification and test methods (ISO 3696:1987) ISO 3165, Sampling of chemical products for industrial use — Safety in sampling ISO 6206, Chemical products for industrial use — Sampling — Vocabulary 3 Description 3.1 Identification 3.1.1 Chemical name 2-Propen-1-aminium,N,N-dimethyl-N-2-propenyl, chloride, homopolymer. 3.1.2 Synonyms or common names  Poly (diallyldimethylammonium chloride).  Poly (dimethyldiallylammonium chloride).  PolyDADMAC. NOTE
The more general terms: "quarternary ammonium polyelectrolyte", "cationic polymer", "cationic polyelectrolyte", "polymer coagulant" and "cationic flocculant" are used, but can also cover other chemicals referred to in other European Standards. 3.1.3 Relative molecular mass Typically in the range of 20 000 to 1 million. 3.1.4 Empirical formula  (C8 H16 N Cl)n- SIST EN 1408:2008

3.1.6 CAS Registry Number 1)  26062-79-3 3.1.7 EINECS reference 2) The conformity of polymers to EINECS is assessed on the basis of the monomers of which they are composed. Thus, EINECS reference numbers do not exist for polymers. DADMAC monomer is listed in EINECS (EINECS reference 230-993-8; CAS Registry Number 7398-69-8). 3.2 Commercial form PolyDADMAC as specified in this standard is an aqueous solution, the concentration (active content) of which is approximately 10 percent 40 percent mass fraction (see 5.2.2.2). 3.3 Physical properties 3.3.1 Appearance The product is a clear, colourless to amber-coloured liquid. 3.3.2 Density The density of the solution depends on the concentration. A typical value is 1,09 g/ml for 40 % mass fraction polyDADMAC at 20 °C. 3.3.3 Solubility The product is miscible with water at all concentrations. 3.3.4 Vapour pressure A typical value is 3,2 kPa for 40 % mass fraction polyDADMAC at 20 °C.

3.3.7 Specific heat Typical specific heats relative to polyDADMAC content are given in Table 2. Table 2 — Specific heats PolyDADMAC Specific heat % mass fraction kJ/kg⋅K 20 3,78 30 3,57 40 3,36
3.3.8 Viscosity, dynamic The viscosity is dependent on molecular mass and active content. Typically, it is in the range of 10 mPa⋅s to 10 000 mPa⋅s. 3.3.9 Critical temperature Not applicable. 3.3.10 Critical pressure Not applicable. 3.3.11 Physical hardness Not applicable. 3.4 Chemical properties PolyDADMAC is a non-hazardous material and not intrinsically reactive. However, in common with many other organic compounds, a strong exothermic reaction will occur if it is brought into contact with strong acids or oxidizing agents. NOTE In dilute solution there can be a reaction with, or destruction by, some of the disinfection and oxidizing agents used in water treatment. 4 Purity criteria 4.1 General This European Standard specifies the minimum purity requirements for polyDADMAC used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities.
