23、rd has been prepared by Technical Committee CEN /TC 165, “Wastewater engineering“, the secretariat of which is held by DIN. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Direc
24、tive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2002, and conflicting nat
25、ional standards shall be withdrawn at the latest by September 2003. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, G
26、reece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. A distinction has been made between initial testing (type tests) and routine quality control requirements (acceptance tests). Attention is drawn to the need for observance of
27、 EEC and/or EFTA and national legal requirements restricting the use of certain materials and to the related marking and labelling requirements. The performance of a sewage network constructed with these products depends not only on the properties of the product as required by this standard but also
28、 on the design and construction of the network as a whole in relation to the environment and conditions of use. 4 EN 588-212001 (E) 1 Scope This Standard gives specifications for asbestos free fibre-cement manholes and inspection chambers for use in buried drains and sewers with gravity flow at atmo
29、spheric pressure. Products covered by this standard include prefabricated elements in as well as prefabricated complete manholes and inspection chambers. It specifies definitions, descriptions, composition, general appearance and finish, geometrical characteristics, mechanical characteristics, accep
30、tance tests, type tests and quality control requirements. NOTE Complete manholes or prefabricated elements may also be used for other purposes such as pumping stations, items of drainage, items for sewage treatment or sewage disposal, when corresponding additional requirements according to the relev
31、ant European Standards are fulfilled. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated referenc
32、es, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
