Introduction
In respect of potential adverse effects on the quality of water intended for swimming pools caused by the
product covered by this European Standard, the following statements apply:
a) This European Standard provides no information as to whether the product may be used without
restriction in any of the Member States of the EU or EFTA.
b) It should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
NOTE 1 Conformity with this European Standard does not confer or imply acceptance or approval of the products in
any of the Member States of the EU or EFTA. The use of the products covered by this European Standard is subject to
regulation or control by National Authorities.
NOTE 2 This product is a biocide and needs to comply with the relevant legislation in force. In the European Union, at
the time of publication, this legislation is Directive 1998/8/EC [1].
1 Scope
This European Standard is applicable to sodium dichloroisocyanurate, anhydrous used directly or used to
prepare commercial formulations for disinfecting swimming pool water. It describes the characteristics of
sodium dichloroisocyanurate, anhydrous and specifies the requirements and the corresponding test methods
for sodium dichloroisocyanurate, anhydrous. It gives information on its use for treating swimming pool water
and determines the rules relating to safe handling and use (see Annex B).
2 Normative reference
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3.4 Chemical properties
The product is a strong oxidant. It is corrosive and hygroscopic; sodium dichloroisocyanurate decomposes
into hydrochloric acid and cyanuric acid. When dissolved in an excess of water, it liberates chlorine by
hydrolysis.
4 Purity criteria
4.1 General
Limits have been given for impurities and toxic substances where these are likely to be present in significant
quantities from the current production process and raw materials. If a change in the production process or raw
materials leads to significant quantities of other impurities or by-products being present, the user shall be
notified.
4.2 Composition of commercial product
The product shall contain at least 62 percent by mass (% (m/m)) of available chlorine.
4.3 Impurities and main by-products
The water content shall be less than 3 % (m/m) of the product.
The sodium chloride content shall be less than 0,05 % (m/m) of the product.
4.4 Toxic substances
NOTE For the purpose of this standard, "toxic substances" are those defined in the EU Directive 80/778/EEC of
15 July, 1980 [1].
The content of toxic substances shall conform to the requirements specified in Table 1.
Table 1 — Toxic substances
Limit mg/kg
Element
of product
Type 1 Type 2
Arsenic (As) max. 10 10
Cadmium (Cd) max. 1 1
Chromium (Cr) max. 6 10
Mercury (Hg) max. 0,02 0,02
Nickel (Ni) max. 3 5
Lead (Pb) max. 4 15
Antimony (Sb) max. 5 5
Selenium (Se) max. 1 1
NOTE Cyanide, which does not exist in a strong oxidising medium
such as sodium dichloroisocyanurate, is not a relevant toxic substance
(see [2]). Pesticides and polycyclic aromatic hydrocarbons are not by-
products of the manufacturing process.
5 Test methods
The sampling and the analytical methods are those described in EN 12931.
6 Labelling - Transportation - Storage
6.1 Means of delivery
The product shall be delivered in fibre or polyethylene drums or semi-bulk containers.
To ensure the purity of the product, the means of delivery shall not have previously been used for any different
product or it shall have been specially cleaned and prepared before use.
4)
6.2 Labelling according to the EU legislation
The following labelling requirements shall apply to sodium dichloroisocyanurate anhydrous at the date of the
publication of this European Standard.
