Plastics piping systems for renovation of underground water supply networks - Part 4: Lining with cured-in-place pipes (ISO 11298-4:2021)

This International Standard, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of underground water supply networks. It applies to the use of various thermosetting resin systems, in combination with compatible fibrous carrier materials and other process-related plastics components.

Kunststoff-Rohrleitungssysteme für die Renovierung von erdverlegten Wasserversorgungsnetzen - Teil 4: Vor Ort härtendes Schlauchlining (ISO 11298-4:2021)

Dieses Dokument legt in Zusammenhang mit ISO 11298 1 Anforderungen und Prüfverfahren für vor Ort gehärtete Schlauch-Liner und Schlauch-Lining-Formstücke für die Renovierung von Wasserversorgungs¬netzen für die Durchleitung von Wasser für den menschlichen Gebrauch, einschließlich Rohwasser-Entnahmeleitungen, fest.
Es gilt für unabhängige (vollständig statisch belastbar, Klasse A) und interaktive (semi-statisch belastbar, Klasse B) Druckleitungs-Liner nach der Definition in ISO 11295, die nicht von der Verklebung mit der vorhandenen Rohrleitung abhängen. Es gilt für die Verwendung verschiedener härtender Harzsysteme (Duroplaste) in Kombination mit kompatiblen, faserigen Trägermaterialien und anderen zum Verfahren gehörenden Kunststoffelementen (siehe 5.1).
Es enthält keine Anforderungen oder Prüfverfahren zur Bestimmung des Widerstands gegen dynamische Einwirkungen oder die Druckfestigkeit von CIPP-Linern bei der Führung durch Bögen. Diese liegen außerhalb des Anwendungsbereiches dieses Dokuments.
Es gilt für vor Ort härtende Schlauchlining-Systeme für den Einsatz bei einer Betriebstemperatur von bis zu 25 °C.
ANMERKUNG   Für Anwendungen mit Betriebstemperaturen größer als 25 °C kann der Systemlieferant Hinweise zu Druckminderungsfaktoren geben.

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 under preparation:

— the ISO 11296 series, Plastics piping systems for renovation of underground non-pressure drainage and

sewerage networks;

— the ISO 11297 series, Plastics piping systems for renovation of underground drainage and sewerage

networks under pressure;

— the ISO 11298 series, Plastics piping systems for renovation of underground water supply networks

(including this document);

— the ISO 11299 series, Plastics piping systems for renovation of underground gas supply networks.

These system standards 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 plastics piping systems components “as

manufactured”.
Each of the system standards comprises a:
— Part 1: General

and all applicable renovation technique family-related parts, which for water supply networks 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;
— Part 10: Lining with sprayed polymeric materials;
— Part 11: Lining with inserted hoses.

The requirements for any given renovation technique family are specified in Part 1, applied in

conjunction with the other relevant part. For example, ISO 11298-1 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 of ISO 11298 to facilitate direct

comparisons across renovation technique families.

Figure 1 shows the common part and clause structure and the relationship between the ISO 11298

series and the system standards for other application areas.

Plastics piping systems for renovation of underground

Part 4:
Lining with cured-in-place pipes
1 Scope

This document, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-

in-place pipes and fittings used for the renovation of water supply networks, which transport water

intended for human consumption, including raw water intake pipelines.

It applies 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. It applies

to the use of various thermosetting resin systems, in combination with compatible fibrous carrier

materials, reinforcement, and other process-related plastics components (see 5.1).

It does not include requirements or test methods for resistance to cyclic loading or the pressure rating

of CIPP liners where passing through bends, which are outside the scope of this document.

It is applicable to cured-in-place pipe lining systems intended to be used at a service temperature of up

to 25 °C.

NOTE For applications operating at service temperatures greater than 25 °C, guidance on re-rating factors

can be supplied by the system supplier.

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;

— ISO 11298, Plastics piping systems for renovation of underground water supply networks (this

document);

— ISO 11299, Plastics piping systems for renovation of underground gas supply networks.

These system standards are distinguished from those for conventionally installed plastics piping

systems because they set requirements for certain characteristics in the “as-installed” condition, after

site processing. This is in addition to specifying requirements for plastics piping system components

“as manufactured”.
Each of the system standards comprises a
— Part 1: General

and all applicable renovation technique family-related parts, which for water supply networks 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;
— Part 10: Lining with sprayed polymeric materials;
— Part 11: Lining with inserted hoses.

The requirements for any given renovation technique family are given in Part 1 applied in conjunction

with the other relevant part. For example, both ISO 11298-1 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 applicable 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 structure and the relationship between ISO 11298 and the system

standards for other application areas.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11298-4:2019(E)
Plastics piping systems for renovation of underground
water supply networks —
Part 4:
Lining with cured-in-place pipes
1 Scope

This document, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-

in-place pipes and fittings used for the renovation of water supply networks which transport water

intended for human consumption, including raw water intake pipelines.

It applies 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. It applies

to the use of various thermosetting resin systems, in combination with compatible fibrous carrier

materials, reinforcement, and other process-related plastics components (see 5.1).

It does not include requirements or test methods for resistance to cyclic loading or the pressure rating

of CIPP liners where passing through bends, which are outside the scope of this document.

It is applicable to cured-in-place pipe lining systems intended to be used at a service temperature of up

to 25 °C.

NOTE For applications operating at service temperatures greater than 25 °C guidance on re-rating factors

can be supplied by the system supplier.
