4.1.7 EINECS reference
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.
NOTE DADMAC monomer is listed in EINECS (EINECS reference 230-993-8; CAS Registry Number 7398-69-8).
Polymers are exempt from registration according to EU Regulation 1907/2006/EC (see [3]), REACH.
Monomer substance(s) and any other substance(s) in the form of monomeric units and chemically bound
substance(s) may have to be REACH registered according to Article 6 of EU Regulation 1907/2006/EC.

4.2 Commercial form
PolyDADMAC as specified in this standard is an aqueous solution, the concentration (active content) of
which is approximately 10 percent to 50 percent mass fraction (see 7.2.2.2).
5 Physical properties
5.1 Appearance
The product is a clear, colourless to amber-coloured liquid.
5.2 Density

6 Chemical properties
6.1 General
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.
6.2 Purity criteria
6.2.1 General
This document 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.
Limits have been given for impurities and chemical parameters where these are likely to be present in
significant quantities from the current production process and raw materials. If the production process
or raw materials lead to significant quantities of impurities, by-products or additives being present, this
shall be notified to the user.
Users of this product should check the national regulations in order to clarify whether it is of appropriate
purity for treatment of water intended for human consumption, taking into account raw water quality,
required dosage and contents of other impurities and additives used in the product not stated in the
product standard.
6.2.2 Impurities and main by-products
Based on the raw materials and manufacturing process (see A.1), there are no significant concentrations
of additional reactants or by products which are relevant to the application of these products in drinking
water treatment.
6.3 Composition of commercial product
The following requirements shall apply to polyDADMAC:
— there shall be no visible insoluble gel or extraneous matter;
— pH shall be in the range 4 to 7.
NOTE Various parameters can be checked as part of assessment of product quality (see 7.2.2).
6.4 Chemical parameters
The products shall contain no more than 5 000 mg of DADMAC monomer per kilogram of active polymer.
NOTE Other chemical parameters and indicator parameters as listed in EU Directive 2020/2184 (see [1]) are
not relevant to polyDADMAC because the raw materials used in the manufacturing process are free of them and
they are not by-products of the manufacturing process.
7 Test methods
7.1 Sampling
7.1.1 General
The recommendations given in ISO 3165:1976 and ISO 6206:1979 shall be followed.
A representative sample of the liquid product, of sufficient mass, shall be obtained immediately after
manufacture or from a newly opened package(s). The sample shall be clearly labelle
