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 in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)

Introduction
Polyethylene reinforced with short glass fibres (PE-sGF) piping systems are pipe systems which consist
of fittings produced by adding short glass fibres into high density polyethylene resins. Their physical and
mechanical properties are influenced by short glass fibre orientation.
For the material subject of this document, the mechanical performances are obtained on the basis of
standards dedicated to thermoplastics. The geometrical characteristics are defined for this material in line
with ISO 3 and ISO 4065.

Polyethylene reinforced with short glass fibres (PE-sGF)
piping systems for industrial applications —
Part 3:
Fittings
1 Scope
This document specifies the fittings made from short glass fibre reinforced polyethylene (PE-sGF)
manufactured by the spiral cross winding method used below ground for the conveyance of fluids in the
following industrial and agricultural contexts:
— chemical plants;
— industrial sewerage engineering;
— power engineering (cooling and general-purpose water supply);
— agricultural production plants;
— water treatment;
— small hydraulic power plants (general-purpose water supply).
This document also specifies the test parameters for the test methods it references.
In conjunction with the other parts of the ISO 22101 series, this document is applicable to PE-sGF fittings,
and to joints with components of PE-sGF or other materials, intended to be used under the following
conditions:
1)
a) a maximum allowable operating pressure (PFA) up to and including 25 bar;
b) an operating temperature of 20 °C as the reference temperature.
NOTE 1 For other operating temperatures, guidance is given in ISO/PAS 22101-1:2022, Annex A.
This document covers a range of maximum allowable operating pressures and gives requirements
concerning colours and additives.
NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,
