Plastics piping systems for renovation of underground gas supply networks - Part 3: Lining with close-fit pipes (ISO 11299-3:2018)

This document, in conjunction with ISO 11299-1, specifies requirements and test methods for close-fit
lining systems intended to be used for the renovation of gas supply networks.
It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable
to polyethylene (PE) pipe of either solid wall single layer or co-extruded layer construction, which is
reduced in the factory or on site to provide a close-fitting independent or interactive pressure pipe
liner, as well as associated fittings and joints for the construction of the lining system. This document is
not applicable for coated PE pipes having a peelable, contiguous, thermoplastics additional layer on the
outside of the pipes.
It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of
20 °C as the reference temperature.
NOTE For other operating temperatures, guidance is given in ISO 4437-5:2014.

Kunststoff-Rohrleitungssysteme für die Renovierung von erdverlegten Gasversorgungsnetzwerken - Teil 3: Close-Fit-Lining (ISO 11299-3:2018)

Dieses Dokument legt in Verbindung mit ISO 11299 1 die Anforderungen und Prüfverfahren für Close-Fit-Lining-Systeme fest, die für die Renovierung von Gasversorgungsnetzwerken verwendet werden.
Es gilt sowohl für vorgefertigte Rohre und Formstücke als auch für das eingebaute Lining-System. Es gilt für Rohre aus Polyethylen (PE) mit entweder einschichtiger Vollwand oder co-extrudiertem Schichtaufbau, die im Werk oder vor Ort verringert werden, um einen eng anliegenden unabhängigen oder interaktiven Druckleitungs-Liner und die dazugehörigen Formstücke und Verbindungen für den Bau des Lining-Systems zu erhalten. Dieses Dokument gilt nicht für beschichtete PE-Rohre, die eine zusätzliche abziehbare, angrenzende, thermoplastische Schicht auf der Außenseite der Rohre aufweisen.
Es gilt für Rohre, Formstücke und Baugruppen aus PE, die für die Verwendung bei einer Betriebstemperatur von 20 °C als Referenztemperatur vorgesehen sind.
ANMERKUNG   ISO 4437 5:2014 enthält Vorgaben für andere Betriebstemperaturen.

Systèmes de canalisations en plastique pour la rénovation des réseaux enterrés de distribution de gaz - Partie 3: Tubage par tuyau continu sans espace annulaire (ISO 11299-3:2018)

Le présent document, conjointement à l'ISO 11299‑1, spécifie les exigences et les méthodes d'essai pour les systèmes de tubage par tuyau continu sans espace annulaire destinés à être utilisés pour la rénovation des réseaux de distribution de gaz.
Il s'applique aux tuyaux et raccords, tels que fabriqués, ainsi qu'au système de rénovation installé. Il s'applique aux tuyaux en polyéthylène (PE) ayant soit une construction monocouche à paroi compacte soit une construction à couches co-extrudées, laquelle est réduite en usine ou sur site pour fournir un tubage autostructurant ou un tubage nécessitant le maintien de l'enveloppe sans espace annulaire, ainsi qu'aux raccords associés et aux assemblages pour la construction du système de rénovation. Le présent document ne s'applique pas aux tuyaux en PE revêtus comportant une couche thermoplastique supplémentaire pelable et contiguë à l'extérieur du tuyau.
Il s'applique aux tuyaux, raccords et montages en PE destinés à être utilisés à une température de fonctionnement de 20 °C, qui est la température de référence.
NOTE       Pour d'autres températures de services, des lignes directrices sont données dans l'ISO 4437-5:2014.

Cevni sistemi iz polimernih materialov za obnovo podzemnih omrežij za oskrbo s plinom - 3. del: Oblaganje s tesno prilagodljivimi cevmi (ISO 11299-3:2018)

Ta dokument v povezavi s standardom ISO 11299-1 določa zahteve in preskusne metode za tesno prilagodljive sisteme oblaganja, ki se uporabljajo za obnovo podzemnih omrežij za oskrbo s plinom.
Uporablja se za cevi in fitinge, kot so izdelani, ter za nameščene sisteme cevi. Uporablja se za polietilenske (PE) cevi s trdno steno iz ene plasti ali s konstrukcijo koekstrudiranih slojev, ki se v tovarni ali na mestu uporabe zmanjša, da se zagotovi tesno prilegajoča se neodvisna ali interaktivna obloga cevi pod tlakom, ter tudi za povezane fitinge in spoje za konstrukcijo sistema cevi. Ne uporablja se za cevi, prevlečene s polietilenom, ki imajo na zunanji strani stični, termoplastični dodatni sloj, ki ga je mogoče odluščiti.
Uporablja se za polietilenske cevi, fitinge in sestave, namenjene za uporabo pri delovni referenčni temperaturi 20 °C.
OPOMBA: Smernice za druge delovne temperature so navedene v standardu ISO 4437-5:2014.

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.

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

ISO 11299-3:2018(E)
Introduction

This document is a part of a System Standard for plastics piping systems of various materials used for

the 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;

— ISO 11299, Plastics piping systems for renovation of underground gas supply networks (this series of

standards).

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”.
This System Standard comprises a:
— Part 1: General

and all applicable renovation technique family-related parts, which, for gas supply networks , include or

potentially include the following:
— Part 2: Lining with continuous pipes;
— Part 3: Lining with close-fit pipes (this document);
— Part 4: Lining with cured-in-place pipes;
— Part 6: Lining with adhesive-backed hoses;
— Part 11: Lining with inserted hoses.

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

with the relevant other part. For example, ISO 11299-1 and this document together specify the

requirements relating to lining with close-fit 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 11299, in order to

facilitate direct comparisons across renovation technique families.

Figure 1 shows the common part and clause structure and the relationship between ISO 11299 and the

System Standards for other application areas.

Plastics piping systems for renovation of underground gas

Part 3:
Lining with close-fit pipes
1 Scope

This document, in conjunction with ISO 11299-1, specifies requirements and test methods for close-fit

lining systems intended to be used for the renovation of gas supply networks.

It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable

to polyethylene (PE) pipe of either solid wall single layer or co-extruded layer construction, which is

reduced in the factory or on site to provide a close-fitting independent or interactive pressure pipe

liner, as well as associated fittings and joints for the construction of the lining system. This document is

not applicable for coated PE pipes having a peelable, contiguous, thermoplastics additional layer on the

outside of the pipes.

It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of

20 °C as the reference temperature.
NOTE For other operating temperatures, guidance is given in ISO 4437-5:2014.
