Overview

EN ISO 11297-4:2018 - Plastics piping systems for renovation of underground drainage and sewerage networks under pressure - Part 4: Lining with cured-in-place pipes (CIPP) specifies requirements and test methods for cured‑in‑place pipe liners and associated fittings used to renovate hydraulically and pneumatically pressurized underground drainage and sewerage systems. Designed for service temperatures up to 50 °C, this standard applies to both independent (fully structural, class A) and interactive (semi‑structural, class B) pressure pipe liners that do not depend on adhesion to the host pipeline.

Key topics and technical requirements

• Scope and applicability
  • Covers CIPP liners made from thermosetting resin systems combined with compatible fibrous carrier materials, reinforcement and process‑related components.
  • Applies to liners that are installed and cured in situ for pressurized sewer and drainage systems.
• Two verification stages
  • “M” stage: requirements and marking for materials, pipes, fittings and ancillary components as manufactured.
  • “I” stage: verification of fitness for purpose in the as‑installed condition after on‑site processing (mechanical, geometric and physical characteristics).
• Characteristics and testing
  • Geometric requirements (liner wall structure and wall thickness), mechanical characteristics and reference conditions for testing are defined.
  • Material characteristics and physical properties are specified for installed liners.
  • Includes requirements for leak tightness of liner terminations and resistance to strain and stress corrosion.
• Exclusions
  • The standard explicitly does not include requirements or test methods for abrasion, cyclic loading or impact resistance.
• Installation and quality assurance
  • Guidance on preparatory work, storage, handling, equipment, installation, process‑related inspection/testing, reconnections and final documentation.

Applications and users

Practical applications:

• Rehabilitation of pressure sewer mains, force mains and other pressurized drainage and sewerage pipelines without full excavation.
• Trenchless renewal projects using CIPP lining to restore structural capacity and hydraulic performance.

Who uses it:

• Utility owners and municipalities specifying renovation contracts.
• Civil and pipeline engineers preparing technical specifications.
• CIPP manufacturers and system suppliers for product development and certification.
• Trenchless contractors, installation crews and quality assurance/testing laboratories.
• Regulators and procurement teams seeking compliance with European and ISO requirements.

Related standards

• ISO 11297-1 - General requirements for renovation system standards (used in conjunction with Part 4).
• ISO 11296-4 - Complementary requirements referenced in the scope.
• ISO 11295 - Definitions and classification of liner structural types.
• Other parts of the ISO 11297 series (Parts 2, 3, 5, 6) cover alternative renovation techniques.

ISO 11297-4:2018(E)
Introduction
This document is a part of a system standard for plastics piping systems of various materials used for
renovation of existing pipelines in a specified application area. System standards for renovation dealing
with the following applications are either available or in preparation:
— ISO 11296: Plastics piping systems for renovation of underground non-pressure drainage and sewerage
networks;
— ISO 11297: Plastics piping systems for renovation of underground drainage and sewerage networks
under pressure (this document);
— ISO 11298: Plastics piping systems for renovation of underground water supply networks;
— ISO 11299: Plastics piping systems for renovation of underground gas supply networks;
These system standards are distinguished from system standards 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 verification of characteristics of plastics piping systems “as-
manufactured”.
Each of the system standards comprises a
— Part 1: General
and all applicable renovation technique family-related parts, which for drainage and sewerage networks
under pressure include or potentially include the following:
— Part 2: Lining with continuous pipes;
— Part 3: Lining with close-fit pipes;
— Part 4: Lining with cured-in-place pipes (this document);
— Part 5: Lining with discrete pipes;
— Part 6: Lining with adhesive-backed hoses.
The requirements for any given renovation technique family are specified in ISO 11297-1, applied in
conjunction with the other relevant part. For example, both ISO 11297-1 and this document together
specify the requirements relating to lining with cured-in place pipes. For complementary information,
see ISO 11295. Not all technique families are pertinent to every area of application and this is reflected
in the part numbers included in each system standard.
A consistent structure of clause headings has been adopted for all parts to facilitate direct comparisons
across renovation technique families.
Figure 1 shows the common part and clause structure and the relationship between the ISO 11297
series and system standards for other applications.
