Overview

ISO/FDIS 11300-1 specifies requirements and test methods for polyethylene (PE) pipes, fittings and assemblies used in the rehabilitation of underground drainage, sewer and water supply networks. The standard covers products used for renovation and trenchless replacement techniques and is applicable to PE solid-wall, co-extruded and coated pipe constructions where layers share the same MRS rating. The reference temperature for design and testing is 20 °C (see ISO 4427:2019 Annex A for applications up to 40 °C).

Key benefits: improved durability, compatibility with trenchless methods, and prescriptive jointing and installation guidance to support reliable rehabilitation projects.

Key Topics

  • Scope and applicability: Defines use for renovation (lining with continuous or close-fit pipes) and trenchless replacement (pipe bursting, pipe extraction, horizontal directional drilling (HDD) and impact moling). Not applicable to existing pipelines themselves.
  • Materials and constructions: Addresses virgin, reprocessable and recyclable PE materials, single-layer and layered (co-extruded) pipes, and coated PE pipes where applicable.
  • Jointing methods: Covers butt fusion and electrofusion jointing, as well as fabricated and injection-moulded fittings and mechanical connections for PE.
  • Fitness for purpose and testing: Specifies general characteristics, mechanical and physical properties, geometric tolerances, marking and sampling requirements to ensure performance in rehabilitation applications.
  • Installation and quality assurance: Includes requirements for preparatory work, storage, handling, equipment (butt fusion, electrofusion, skids, winching and inspection tools), simulated installations, process-related testing and final inspection.
  • Normative annexes: Additional, technique-specific requirements are provided in annexes covering continuous lining, close-fit lining, trenchless replacement methods, layered pipes, and factory-folded heat-reverted PE pipe memory testing.

Applications

ISO/FDIS 11300-1 is aimed at stakeholders involved in sewer and water network rehabilitation and replacement projects:

  • Utilities and municipal engineers specifying materials for trenchless renewal projects.
  • Designers and contractors executing lining works (continuous or close-fit) and trenchless replacement (pipe bursting, HDD, impact moling).
  • Manufacturers and suppliers of PE pipes, fittings and jointing systems seeking conformity with international requirements.

Practical advantages include minimizing open excavation, maintaining service continuity during works, and ensuring material compatibility with common rehabilitation techniques.

Related Standards

  • ISO 4427:2019 (referenced for elevated operating temperatures up to 40 °C)
  • Other ISO and regional standards on PE piping materials, fusion jointing and potable water suitability may be relevant; consult the normative references listed in ISO/FDIS 11300-1.

This document provides a consolidated framework for specifying PE materials and assemblies used specifically in trenchless and renovation rehabilitation, helping project teams select compliant products and apply consistent installation and testing practices.

Introduction
This document is a part of a series of International Standards concerning piping systems of various materials
used for the rehabilitation of existing pipelines in a specified application area:
— ISO 11300 series: Piping systems for rehabilitation of underground drains, sewers and water supply
networks;
— ISO 11301 series: Piping systems for rehabilitation of underground gas supply networks.
The ISO 11300 series and the ISO 11301 series are subdivided into parts covering a specific material per
pipe system.
The ISO 11300 series is subdivided in four parts:
— Part 1: Polyethylene (PE) material (this document);
— Part 2: Thermoset composite materials;
— Part 3: PVC-U material;
— Part 4: Thermoplastic composite materials.
These documents cover various techniques for renovation and trenchless replacement. Furthermore, they
are distinguished from those for conventionally installed plastics piping systems by the requirement to
verify certain characteristics in the “as-installed” condition, after site processing. This is in addition to
specifying requirements for piping system components “as manufactured”.
A consistent structure of clause headings has been adopted for all parts of the ISO 11300 series and the
ISO 11301 series, in order to facilitate direct comparisons across renovation technique families.
Figure 1 shows the clause structure and the relationship between the ISO 11300 series and the ISO 11301 series.
For complementary information, see ISO 11295.

Introduction
This document is a part of a series of International Standards concerning piping systems of various materials
used for the rehabilitation of existing pipelines in a specified application area:
— — ISO 11300 series: Piping systems for rehabilitation of underground drains, sewers and water supply
networks;
— — ISO 11301 series: Piping systems for rehabilitation of underground gas supply networks.
The ISO 11300 series and the ISO 11301 series are subdivided into parts covering a specific material per pipe
system.
The ISO 11300 series is subdivided in four parts:
— — Part 1: Polyethylene (PE) material (this document);
— — Part 2: Thermoset composite materials;
— — Part 3: PVC-U material;
— — Part 4: Thermoplastic composite materials.
These documents cover various techniques for renovation and trenchless replacement. Furthermore, they are
distinguished from those for conventionally installed plastics piping systems by the requirement to verify
certain characteristics in the “as-installed” condition, after site processing. This is in addition to specifying
requirements for piping system components “as manufactured”.
A consistent structure of clause headings has been adopted for all parts of the ISO 11300 series and the ISO
11301 series, in order to facilitate direct comparisons across renovation technique families.
Figure 10 shows the clause structure and the relationship between the ISO 11300 series and the ISO 11301
series.
For complementary information, see ISO 11295.

Introduction
Le présent document est une partie d’une série de Normes Internationales concernant les systèmes de
canalisations à base de matières variées, utilisés pour la réhabilitation de canalisations existantes pour une
zone d’application spécifiée:
— série ISO 11300: Systèmes de canalisations pour la réhabilitation des branchements, des collecteurs
d’assainissement et des réseaux d’alimentation en eau enterrés;
— série ISO 11301: Systèmes de canalisations pour la réhabilitation des réseaux enterrés de distribution de
gaz.
La série ISO 11300 et la série ISO 11301 sont subdivisées en parties couvrant une matière spécifique par
système de canalisations.
La série ISO 11300 est subdivisée en quatre parties:
— Partie 1: Matériau polyéthylène (PE) (le présent document);
— Partie 2: Matériaux composites thermodurcissables;
— Partie 3: Matériau PVC-U;
— Partie 4: Matériaux composites thermoplastiques.
Ces docuemnt couvrent diverses techniques de rénovation et de remplacement sans tranchée. En outre, elles
se distinguent de celles relatives aux systèmes de canalisations en plastique installées traditionnellement
du fait qu’elles établissent des exigences concernant certaines caractéristiques liées aux conditions «tel
qu’installé», après mise en œuvre sur le site. Ces exigences viennent s’ajouter à celles des composants du
système de canalisations «tels que fabriqués».
Une structure cohérente des titres des articles a été adoptée pour toutes les parties de la série ISO 11300 et
de la série ISO 11301 afin de faciliter des comparaisons directes entre les différentes familles de techniques
de rénovation.
La Figure 1 illustre la structure des articles et la relation entre la série ISO 11300 et la série SO 11301.
