European foreword
This document (prEN 14944-2:2023) 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 CEN Enquiry.
This document describes a test method to determine the influence(s) of site-applied cement based
materials and associated non-cement based products/materials on organoleptic parameters and the
migration of organic substances (TOC) in water intended for human consumption.
This document will result in one of a series of standards that support standards for the approval of
products and materials in contact with water intended for human consumption.
This document is part of a series dealing with the influence of cement based and associated non-cement
based products/materials on water intended for human consumption, including:
— Part 1: Influence of factory-made cement based products on organoleptic parameters and migration of
organic substances (TOC)
— Part 2: Influence of site-applied cement based materials and associated non-cement based
products/materials on organoleptic parameters and migration of organic substances (TOC)
— Part 3: Migration of substances from factory-made cement based products.
— Part 4: Migration of substances from site-applied cement based materials and associated non-cement
based products/materials.

1 Scope
This document specifies a method to determine the influence of site-applied cement based materials and
associated non-cement based products/materials (including pre-packaged mortars) on the odour,
flavour, colour, turbidity and total organic carbon (TOC) of test waters after contact with the products.
This document is applicable to site-applied or site-formed cement based materials intended to be used
for the transport and storage of water intended for human consumption, including raw water used for
the production of drinking water. It is also applicable to individual constituents of cement based
products/materials and to associated non-cement based products/materials.
Site-applied or site-formed cement based materials which cannot be cast as cubes or prisms e.g. some
spray applied systems, should be tested as factory made cement based products according to
EN 14944−1.
NOTE Tests with the specified test water will not necessarily be representative of materials used in different
kinds of waters and especially very soft waters.
