5、.The UK has had a coding system, the Manual of Sewer Condition Classification (MSCC), for many years. Clause 5.4 allows the national equivalent codes to be used in place of the language independent codes described in EN 13508-2. A national equivalent coding system complying with the requirements of
6、EN 13508-2 has been produced and is described in National Annex NB. This is very similar to the MSCC coding system.Users with archives of data coded according to the MSCC can retain this data. Guidance on converting such data into the system described in EN 13508-2 can be found in National Annex NA.

This European Stan
30、dard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2011, and conflicting national standards shall be withdrawn at the latest by November 2011. This document includes Corrigendum 1 issued by CEN on 21 March 20
31、07 and Amendment 1 approved by CEN on 17 March 2011. This document supersedes EN 13508-2:2003. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. The modifications of the related CEN Corrigendum have been implemented at the appropriate places in the
32、text and are indicated by the tags . The Standard series EN 13508 “ Condition of drain and sewer systems outside buildings “ contains the following parts Part 1: General requirements Part 2: Visual inspection coding system Other parts, dealing with other methods of inspection, can be added later. In
33、 drafting this part of this European Standard account has been taken of other available standards, in particular EN 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 training of inspection person
34、nel, a transition period is granted until (DAV + 36 month) for the withdrawal of conflicting national standards and the application of this standard. Where there are existing inspection programmes to meet legal requirements commenced before the publication of this standard, it is permitted to comple
35、te such programmes using the original coding system. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finlan

BS EN 13508-2:2003+A1:2011EN 13508-2:2003+A1:2011 (E) 6 Introduction In producing thi
37、s draft standard, existing national coding systems have been reviewed. To preserve the link with existing data, TC165/WG22 has tried to ensure that there is an equivalent code, or combination of codes, for every observation recorded in an existing national system. !This will allow existing data to b
38、e transferred to the new coding system.“ At present the amount of detail recorded varies between countries. The choice of features to be recorded and the extent of detail to be included is left to the employing authority. Before the standard can be fully applied, extensive retraining of operators an
39、d modification of software will be necessary. 1 Scope !This European Standard is applicable to the investigation and assessment of drain and sewer systems outside buildings.“ !It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where the wastewater le
40、aves 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.“ Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building. This part of the European Standa
41、rd 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 be used for pressure and vacuum systems in accordance with the requirements of the employing authority.
42、!Visual inspection of drain and sewer systems can be carried out as part of the investigation in order to undertake the assessment.“ This part of the European Standard does not generally specify requirements for carrying out inspections. 2 Normative references !The following referenced documents are
43、 indispensable for the application of this document. For dated references, only the edition cited applies.
