Foreword
This document (FprEN 13176:2014) has been prepared by Technical Committee CEN/TC 164 “Water supply”,
the secretariat of which is held by AFNOR.
This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede EN 13176:2008.
Significant technical difference between this edition and EN 13176:2008 is as follows:
a) deletion of reference to EU Directive 67/548/EEC of June 27, 1967 in order to take into account the latest
Regulation in force (see [2]);
b) clause 6.2 – updating of risk and safety labelling according to EU Regulation [2] and its latest Adaptations
to Technical Progress).

4 Purity criteria
4.1 General
This European Standard specifies the minimum purity requirements for Ethanol 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.
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, contents of other impurities and additives used in the product not stated in the product standard.
Limits have been given for impurities and chemicals 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(s) to significant quantities of impurities, by-products or additives being present, this shall be
notified to the user.

NOTE The commercial product may contain up to a mass fraction of 5 % water.
4.3 Impurities and main by-products
The acetaldehyde content shall not exceed 100 mg/kg of pure ethanol.
4.4 Chemical parameters
NOTE For the purpose of this European Standard, "chemical parameters" are those defined in the
EU Directive 98/83/EC of 3 November 1998 (see [1]).
The content of chemical parameters shall conform to the requirements specified in Table 2.

5 Test methods
5.1 Sampling
5.1.1 Relevant standards
Observe the general recommendations of ISO 3165 and take account of ISO 6206.
5.1.2 Sampling from drums and bottles
5.1.2.1 General
5.1.2.1.1 Mix the contents of the container to be sampled by shaking the container, by rolling it or by
rocking it from side to side, taking care not to damage the container or spill any of the liquid.
5.1.2.1.2 If the design of the container is such (for example, a narrow-necked bottle) that it is impracticable
to use a sampling implement, take a sample by pouring after the contents have been thoroughly mixed.
Otherwise, proceed as described in 5.1.2.1.3.

5.1.2.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from
the surface as described in 5.1.2.2; otherwise, take samples as described in 5.1.2.3.
5.1.2.2 Surface sampling
Take a sample using a suitable ladle. Lower the ladle into the liquid until the rim is just below the surface, so
that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering
to the ladle to drain off. If necessary, repeat this operation so that, when the other selected containers have
been sampled in a similar manner, the total volume of sample required for subsequent analysis is obtained.
5.1.2.3 Bottom sampling
Take a sample using an open sampling tube, or a bottom-valve sampling tube, suited to the size of container
and the viscosity of the liquid.
When using an open sampling tube, close it at the top and then lower the bottom end to the bottom of the
container. Open the tube and move it rapidly so that the bottom of the tube traverses the bottom of the
container before the tube is filled. Close the tube, withdraw it from the container and allow any liquid adhering
to the outside of the tube to drain off.
When using a bottom-valve sampling tube, close the valve before lowering the tube into the cont
