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of an identical text or by endorsement, at the latest by May 2015 and conflicting national standards shall be withdrawn at the latest by August 2016. Attention is drawn to the p
22、ossibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Tra

EN 16397, Flexible couplings, contains the following parts: Part 1: Performance requirements; Part 2: Characteristics a
24、nd testing for metal banded flexible couplings, adaptors and bushes. This standard takes into account the requirements of EN 476. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria,
25、 Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, S

DIN EN 16397-2:2015-01 EN 16397-2:2014 (E) 4 1 Scope This European Standard specifies the materials and dimensions for metal banded flexible couplings and adaptors and bushes for use with pipes and fittings in drain and sewer systems, usually operated under
27、 gravity and periodic hydraulic surcharge, both above and below ground inside or outside buildings and intended to connect pipes for: repair of damaged pipelines; connecting pipes of different materials and/or diameters; jointing short/cut lengths of pipe; jointing specific pipe systems; jointing po
28、st-inserted preformed junctions. The coupling consists of a moulded or extruded rubber sleeve with two stainless steel clamping bands with or without a stainless steel shear band. The clamping bands enable the sleeve to form a seal with the pipes to be joined. The shear band gives resistance to shea
29、r forces. Connections may be made between pipes which cannot be satisfactorily joined by a coupling alone, of dissimilar sizes or material, by using an appropriate bush or bushes with the coupling or by using an appropriate adaptor. 2 Normative references The following documents, in whole or in part
