| Title | Plastics piping systems for renovation of underground water supply networks - Part 4: Lining with cured-in-place pipes (ISO 11298-4:2021) |
| Work Item Number | 00155930 |
| Abstract/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. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
