Conditions of drain and sewer systems outside buildings - Part 2: Visual inspection coding system
This European Standard is applicable to the establishment of the condition of sewers, drains, manholes and inspection chambers by inspection, status codification and consideration of external factors and other information. It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where the sewage leaves a building or roof drainage system, or enters a road gully, to the point where it is discharged into a treatment works or receiving water.
Zustandserfassung von Entwässerungssystemen außerhalb von Gebäuden - Teil 2: Kodiersystem für die optische Inspektion
Diese Europäische Norm gilt für die Zustandserfassung von Entwässerungssystemen durch Inspektion, Grundlagenerfassung und Berücksichtigung von äußeren Bedingungen sowie weiteren Informationen.
Sie gilt für Entwässerungssysteme, welche hauptsächlich als Freispiegelsysteme betrieben werden, von dem Punkt an, wo das Abwasser das Gebäude bzw. die Dachentwässerung verlässt oder in einen Straßeneinlauf fließt, bis zu dem Punkt, wo das Abwasser in eine Behandlungsanlage oder in einen Vorfluter eingeleitet wird. Abwasserleitungen und -kanäle unterhalb von Gebäuden sind hierbei eingeschlossen, solange sie nicht Bestandteil der Gebäudeentwässerung sind.
Dieser Teil der Europäischen Norm legt ein Kodiersystem für die Beschreibung der Beobachtungen fest, die im Inneren von Abwasserleitungen und -kanälen, Schächten und Inspektionsöffnungen bei der optischen Inspektion gemacht wurden. Gegebenenfalls kann dieser Teil in Übereinstimmung mit den Anforderungen des Auftraggebers auch auf Druck- und Unterdrucksysteme angewendet werden.
Dieser Teil der Europäischen Norm enthält im Allgemeinen keine Anforderungen an die Durchführung von Inspektionen.
Condition des réseaux d'évacuation et d'assainissement a l'extérieur des bâtiments - Partie 2 : Systeme de codage de l'inspection visuelle
La présente Norme européenne s'applique a la détermination de l'état des réseaux d'évacuation et d'assainissement par inspection, codification de l'état et prise en compte de facteurs extérieurs et d'autres informations.
Elle s'applique aux réseaux d'évacuation et d'assainissement, principalement les réseaux gravitaires, a partir du point ou les effluents quittent un bâtiment ou un systeme d'évacuation par le toit, ou pénetrent dans un avaloir de chaussée, jusqu'au point ou ils se déversent dans une station d'épuration ou un milieu récepteur aquatique. Les branchements et collecteurs situés sous des bâtiments sont inclus, a condition qu'ils ne fassent pas partie du réseau d'évacuation du bâtiment.
La présente partie de cette Norme européenne définit un systeme de codage pour la description de l'état interne des réseaux d'évacuation et d'assainissement, et des regards de visite et des chambres d'inspection, relevé par inspection visuelle. Dans certains cas, elle peut également etre utilisée pour les systemes sous pression ou sous vide conformément aux exigences de l'autorité responsable.
La présente partie de cette Norme européenne ne spécifie aucune exigence concernant la réalisation des inspections.

EN 13508-2:2003 (E)4ForewordThis document (EN 13508-2:2003) has been prepared by Technical Committee CEN/TC 165 “Wastewaterengineering”, the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latestby May 2006.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.The Standard series EN 13508 " Condition of drain and sewer systems outside buildings " contains the followingparts¾ Part 1: General requirements¾ Part 2: Visual inspection coding systemOther parts, dealing with other methods of inspection, can be added later.In drafting this part of this European Standard account has been taken of other available standards, in particularEN 752 “Drain and sewer systems outside buildings”To allow for the alteration of existing data and coding system software in accordance with this standard and trainingof inspection personnel, a transition period is granted until (DAV + 36 month) for the withdrawal of conflictingnational standards and the application of this standard.Where there are existing inspection programmes to meet legal requirements commenced before the publication ofthis standard, it is permitted to complete such programmes using the original coding system.
EN 13508-2:2003 (E)5IntroductionIn producing this draft standard, existing national coding systems have been reviewed. To preserve the link withexisting data, TC165/WG22 has tried to ensure that there is an equivalent code, or combination of codes, for everyobservation recorded in an existing national system. This should allow existing data to be transferred to the newcoding system.At present the amount of detail recorded varies between countries. The choice of features to be recorded and theextent of detail to be included is left to the employing authority.Before the standard can be fully applied, extensive retraining of operators and modification of software will benecessary.1 ScopeThis European Standard is applicable to the establishment of the condition of drain and sewer systems byinspection, status codification and consideration of external factors and other information.It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where thesewage leaves a building or roof drainage system, or enters a road gully, to the point where it is discharged into atreatment works or receiving water. Drains and sewers below buildings are included provided that they do not formpart of the drainage system of the building.This part of the European Standard specifies a coding system for the description of the internal condition of drains,sewers, manholes and inspection chambers identified through visual inspection.
Where appropriate, it can also beused for pressure and vacuum systems in accordance with the requirements of the employing authority.This part of the European Standard does not generally specify requirements for carrying out inspections.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

EN 13508-2:2003 (E)114 Sources of additional informationThis standard specifies a coding system for visual inspection of drain and sewer systems. For further guidance onthe execution of visual inspection in various countries reference should be made to national documents until suchtime as fully comprehensive European Standards are available.The documents listed in annex H contain details, which can be used in the framework of this part.5 General5.1 PurposeEN 752-5 recommends the use of a uniform standard coding system to ensure that results from visual inspectionscan be compared. This part of this standard specifies a system, which can be used to objectively record the visualinformation from the inspection. It does not include methods for assessing the condition of the drain or sewer asthis requires subjective judgements and the use of additional information.The coded information can be used for one or more of the following purposes:¾ to assess the performance deficiencies as part of the development of a rehabilitation plan (see EN 752-5:1997,clause 7);¾ to provide information for use in the planning of maintenance activities, e.g. sewer cleaning programmes (seeEN 752-7:1998, clause 6);.¾ to investigate specific maintenance or operational problems (see EN 752-7:1998, clause 8);¾ the recording of inventory data (see EN 752-5:1997, clause 7)5.2 MethodsThe visual inspection can be carried out in one of the following ways:¾ inspection of the pipeline from within the pipeline;¾ inspection of the pipeline from within the manhole or inspection chamber;¾ inspection of the manhole or inspection chamber from within the manhole or inspection chamber;¾ inspection of the manhole or inspection chamber from the surface.Several inspection techniques can be used such as:¾ remotely controlled CCTV camera;¾ man entry;¾ mirrors;¾ photographic camera.The personnel involved in inspection work shall be adequately trained in the inspection methods and in the codingsystem.The inspection shall be carried out sufficiently slowly to enable all features to be observed. Where a closed circuittelevision camera is used, the camera should only be moved along the pipe when the lens is pointing forward in thedirection of the axis of the sewer.
EN 13508-2:2003 (E)12The relevant authority can prescribe requirements regarding the health, safety and welfare of the public and/orpersonnel. The work should be carried out in accordance with EN 752-7:1998, clause 11.5.3 The use of the coding systemThe coding system specified in this European Standard for drains and sewers is described in clauses 6, 7 and 8.The coding system specified in this European Standard for manholes and inspection chambers is described inclauses 9, 10 and 11.
