ÖNORM EN 1671

1.1 General This European Standard specifies the performance, design, operation, maintenance and installation with related verifcation and test method for positive pressure driven sewerage systems outside buildings carrying wastewater . It does not provide for the evaiuation of conformity of systems to this European Standard. It does not specify the detaii design or materials of consbuction of individual components within the system. This European Standard covers positive pressure sewerage systems designed for transporting wastewater, defined as: Domestic sewage arising fkom dwellings and commercial properties but excluding stormwater and rainwater. This European Standards covers the design of a PSS and some requirements of products used together with the PSS in order to ensure the performaace of a PSS. The components of the system and in conjunction with the system should be evaluated by reference to the appropriate product standard. In the absence of a product standard, this standard may be used as a reference for drawing up a specitication for that product. 1.2 Limit of Design Intermediate pressure booster equipment is not covered in this standard. The use of compressed air as the only means of generating pressure is not covered in this standard. The design requirements of this standard are minimum requirements and do not constitute in themselves a cornprehensive design sufficient to ensure a correctly functioning system. Every system must be individually designed. Where proprietary components are employed, account should be taken of the advice of the component suppfier. 1.3 Appliaition of Pressure Sewerage Systems (PSS) Information on the use of Pressure Sewerage Systems is given in A. 1. 1.4 Sources of Additional Information Documents which, whilst relating to specinc systems, contain detaiis which can be used within the frarnework of this standard are listed in informative annex C,
