3、he official English language version ofEN 13564-1:2002. EN 13564-1:2002 is a candidate “harmonized” European Standard and filly takes into account the requirements of the European Commission mandate M1 18, Wmte water engineenngproducts, given under the EU Construction Products Directive (89/1OEEC),
4、and intended to lead to CE marking. The date of applicability of EN 13564-1:2002 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the OfJial Journal of the European Communities. EN 13564-1 is the subjec
5、t of transitional arrangements agreed under the European Commission mandate. The European Commission in consultation with Member States have agreed a transition period for the Co-existence of “harmonized” European Standards and their corresponding national standard(s). It is intended that this perio
6、d will comprise a period, usually nine months, after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this ceexistence p
7、eriod, the national standard(s) will be withdrawn. In the UK, there are no corresponding national standards. The UK participation in its preparation was entrusted to Technical Committee B/505, Wastewater engineering, which has the responsibility to: - aid enquirers to understand the text; present to
8、 the responsible internationalEuropean committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. - - A list of organizations represented on this committee can be o

29、ms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 anti-flooding device device, installed either directly in the pipework of a drainage system or incorporated in a floor gully intended to protect buildings from internal flooding, .e. rooms w
30、hich are below the flood level 3.2 automatic closure device part of the anti-flooding device which closes the pipeline automatically when backflow occurs 3.3 emergency closure device part of the anti-flooding device which enables closure of the pipeline by manual or mechanical action 3.4 warning dev
31、ice device which indicates when the closing action is activated 4 Types of anti-flooding devices Anti-flooding devices are divided into different types in accordance with their design and intended use as follows: Type O: Type 1: Type 2: Type 3: Type 4: Type 5: Anti-flooding device for use in horizon
32、tal pipes having only an automatic closure device. Anti-flooding device for use in horizontal pipes having an automatic closure device and an emergency closure device, where this emergency closure device may be combined with the automatic closure device. Anti-flooding device for use in horizontal pi
33、pes having two automatic closure devices and an emergency closure device, where this emergency closure device may be combined with one of the automatic closure devices. Anti-flooding device for use in horizontal pipes having an automatic closure device actuated by external energy (electrically, pneu
34、matically or other) and an emergency closure being independent of the automatic closure device. Anti-flooding device incorporated in waste fittings or floor gullies having an automatic closure device and an emergency closure device, where this emergency closure device may be combined with the automa
35、tic closure device. Anti-flooding device incorporated in waste fittings or floor gullies having two automatic closure devices and an emergency closure device, where this emergency closure device is combined with one of the automatic closure devices. National regulations for the choice and the applic
36、ation of these types are given in annex A. 5 Materials When tested in accordance with 3.1 or 3.2 of prEN 13564-2:2001 the materials for anti-flooding devices shall withstand domestic wastewater - for types O, 1,2 and 3 up to a temperature of 75 OC; - for types 4 and 5 up to a temperature of 93 OC; 4
37、 EN 13564-1 12002 (E) Materials which are not inherently corrosion resistant shall be protected accordingly. 6 Performance, design and construction 6.1 General requirements Anti-flooding devices shall automatically close when backflow occurs, .e. when or before the pipe is filled, and they shall all
38、ow the normal flow to reoccur when backflow ceases. The automatic closure device shall not impede the flow under low flow conditions. Therefore, it shall open when there is a depth of water on the up-stream side of 50 % of the pipe diameter or a maximum of 50 mm. Internal surfaces shall be smooth, p
39、ermitting an unhindered flow of waste water. Steps in invert level shall be limited to 6 mm. In order to ensure the free operation of the moving parts there shall be a minimum clearance around the circumference of the moving parts and the body of the anti-flooding device of 0,05 x DN of the outlet i
40、n mm, and not less than 6 mm for outlets greater than DN 100. Flaps shall not be floated upwards during backflow. When tested for effectiveness in accordance with 3.4.2.4, 3.4.2.5 and 3.4.4 of prEN 13564-2:2001 the leakage for each individual test cycle (A or B or for the testing in-situ) shall not
41、exceed 0,5 I. The dimensions of sockets and/or spigots of anti-flooding devices shall be compatible with pipes/fittings of the same nominal diameter in accordance with relevant European Standards. The nominal size of the outlet shall not be smaller than the nominal size of the inlet. All connections
42、 to and from and all joints on the anti-flooding devices shall be designed to be watertight in accordance with the relevant European Standards or in their absence with EN 476. The moving parts of anti-flooding devices shall be detachable, or capable of being dismantled in situ. The mode of actuation
43、 and the direction of closing on the emergency closure device shall be clearly and durably indicated. Where this is actuated by the rotation of an operating element this shall close clockwise. Where simulation of backflow of the automatic closure device in the installed position is requested, the an
44、ti-flooding device shall be provided with appropriate means for testing in situ. For this purpose some anti-flooding devices may be disassembled and the functional components tested separately. Where required, a threaded connection of G 112 in accordance with IS0 228-1 shall be provided. 6.2 Special
45、 requirements of anti-flooding devices of types O, 1 and 2 The operational closure device shall open, to allow the passage of water, to a depth of flow of minimum 70 % of the internal diameter of the incoming pipe. The body of the anti-flooding devices shall retain a minimum of 90 % of the cross sec
46、tional area of the incoming pipe. When tested in accordance with 3.3 of prEN 13564-2:2001 the body including covers shall be watertight up to 0,5 bar. 6.3 Special requirements of anti-flooding devices of type 3 The automatic closure device and the emergency closure device shall be fully opened excep
47、t when backflow occurs. When these closure devices are fully opened they shall maintain not less than 90 % of the cross sectional area of the incoming pipe. The closing process shall commence at the latest when the backflow level is equal to 100 mm, measured from the top of the outlet of the anti-fl
48、ooding device. The closing time shall not exceed 60 s. When tested in accordance with 3.3 of prEN 13564-2:2001, the body including covers shall be watertight up to 0,5 bar. When tested in accordance with 3.4.3 of prEN 13564-2:2001 (textile test) the leakage for each test cycle shall not exceed 0,5 I
49、. 5 EN 13564-1 12002 (E) The closed position of the automatic closure device shall be indicated by either optical or acoustical means, even in the event of power failure. 6.4 Special requirements of anti-flooding devices of types 4 and 5 Waste fittings for sanitary appliances and floor gullies in which anti-flooding devices are incorporated shall comply with prEN 274-1 and EN 1253-1 respectively. Gratings of such floor gullies shall not be fixed to the automatic and/or emergency closure device. Anti-flooding devices shall have provision for cleaning and rodding the upstream
