Description (English):

This document provides a scheme for the assessment of conformity of RFC products for the rehabilitation of existing pipelines, in accordance with the applicable parts of ISO 11296, ISO 11297 and ISO 11298, and intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures. It applies to cured-in-place pipe (CIPP) products only. It applies to non-pressure pipe liners, and to independent (fully structural, class A) and interactive (semi-structural, class B) pressure pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline. NOTE In order to help the reader, summary tables of overall scheme requirements are provided in Annex E.

Abstract

Overview

ISO/TS 23818-2:2021 is a technical specification for the assessment of conformity of resin-fibre composite (RFC) products used in the rehabilitation of existing pipelines. Focused specifically on cured‑in‑place pipe (CIPP) systems, this ISO/TS defines a conformity‑assessment scheme to be included in a manufacturer’s quality plan and used in certification procedures. It covers non‑pressure liners and pressure liners that are independent (fully structural, class A) or interactive (semi‑structural, class B), provided they do not rely on adhesion to the host pipeline.

Key topics and requirements

Scope & applicability: Applies only to RFC CIPP products for pipeline rehabilitation (drainage, sewerage, water and relevant pressure applications as defined by system standards).
Conformity scheme: Framework for integrating conformity assessment into a manufacturer’s quality management system and for third‑party certification.
Testing and inspection program:
- Grouping (size, wall strength, fittings)
- Type testing (TT) to demonstrate conformance of materials and products
- Batch release tests (BRT) for lining‑tube batches
- Process verification tests (PVT‑I) during installation to ensure as‑installed performance
- CIPP product verification tests (CPVT) and audit tests (AT) to verify ongoing compliance
- Indirect tests and test record requirements
Normative test procedures: Detailed test procedures for non‑pressure and pressure applications are provided in normative annexes (Annex A and B). Annex E contains summary tables of scheme requirements to aid implementation.
Traceability & documentation: Emphasizes maintaining records as part of the quality plan and for certification/audit evidence.

Practical applications

Ensures RFC CIPP products used in pipeline rehabilitation meet recognized performance and quality criteria.
Supports manufacturers in establishing robust quality control, batch release procedures and documentation for certification.
Guides installers and contractors on process verification during onsite CIPP installation to confirm as‑installed performance.
Enables certification bodies and testing laboratories to design audit and testing schedules consistent with ISO conformity assessment principles.

Who should use this standard

RFC and CIPP manufacturers developing quality plans and seeking product certification.
Installers/contractors performing CIPP rehabilitation who must demonstrate process control and compliance.
Certification bodies, inspection bodies and testing laboratories that perform audits, type testing and batch release testing.
Asset owners and engineering consultants specifying compliance requirements for pipeline renovation projects.
