General information on cationic polyacrylamides.16 A.1 Origin.16 SIST EN 1410:2008

1 Scope This European Standard is applicable to cationic polyacrylamides used for treatment water intended for human consumption. It describes the characteristics of cationic polyacrylamides and specifies the requirements and the corresponding test methods for cationic polyacrylamides. It gives information on their 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 ISO 8213, Chemical products for industrial use — Sampling techniques — Solid chemical products in the form of particles varying from powders to coarse lumps 3 Description 3.1 Identification 3.1.1 Chemical names Copolymer of acrylamide and amine ester or amide. 3.1.2 Synonym or common name Cationic polyacrylamide. NOTE The more general terms: "cationic polymer", "cationic polyelectrolyte" 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 1 to 20 million. 3.1.4 Empirical formula ()()−−−yxAONHCONHC53dcba SIST EN 1410:2008
