Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights

DRAFT International Standard ISO/DIS 13182:2025(en)

Classification for discrete polymer fibre for fibre-reinforced
cementitious composites
1 Scope
This document specifies discrete polymer fibres with a nominal length of 80 mm or less mixed in concrete and
mortar. The quality and performance specified in this standard are the raw material resin of discrete polymer
fibres, nominal fibre diameter and its allowable range, nominal fibre length and its allowable range, fibre
cross-sectional shape, fibre longitudinal shape, grade of fibre strength, and grade of fibre elasticity.
There are a wide variety of discrete polymer fibres used to reinforce cement composites. Currently, in discrete
polymer fibres products distributed as industrial products, there are many types of raw material resins and
various shapes. In addition, the applications that have been used in practical fields are so wide, from structural
applications that require high mechanical reinforcement performance to crack control and peeling prevention
that are easier to use. Therefore, to select an app
