| Title | Plastics piping systems used for the rehabilitation of pipelines — Classification and overview of strategic, tactical and operational activities |
| Work Item Number | 00155A1M |
| Abstract/Scope | This document specifies the steps of the overall process of pipeline rehabilitation, comprising: — information on strategic and tactical activities: a) investigation and condition assessment of the existing pipeline; b) pipeline rehabilitation planning. — information on and requirements for operational activities: c) project specification; d) applications of techniques; e) documentation of the design and application process. Definitions and classification of families of renovation and trenchless replacement techniques are provided, and their respective features described. Areas of application covered include underground drainage and sewerage networks and underground water and gas supply networks. The following aspects are not covered by the scope of this document: — new construction provided as network extensions; — calculation methods to determine, for each viable technique, the characteristics of lining or replacement pipe material needed to secure the desired performance of the rehabilitated pipeline; — techniques providing non-structural pressure pipe liners; — techniques for local repair. It is the responsibility of the designer to choose and design the renovation or trenchless replacement pipeline system. |

(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Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn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.
