25、hnical Committee CEN/TC 166 “Chimneys”, the secretariat of which is held by ASI. 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of an identical text or by endorsement, at the latest by October 2016, and conflicting national standards shall be withdrawn
26、 at the latest by January 2018. Attention is drawn to the possibility 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
27、to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the nationa

BS EN 16475-3:2016EN 16475-3:2016 (E) 6 Introduction This standard forms a part of the series of standards for chimney accessories: Part 1: Silencers
30、 Part 2: Chimney fans Part 3: Draught regulators, standstill opening devices and combined secondary air devices (this part) Part 4: Flue dampers Part 5: Explosion/implosion relief devices Part 6: Access components Part 7: Rain caps Independent draught regulators are for the purpose of reducing negat
31、ive pressure that is too large in the chimney, which can result through the use of commercially available cross-section dimensions, despite being designed e.g. according to EN 13384-1:2015, Calculation method for chimneys serving single appliance. They serve to increase the flue gas speed and the ve
32、ntilation of the chimney, for the purpose of drying out (see explanations). Standstill opening devices interlocked with the combustion system are exclusively for the purpose of ventilating the chimney during standby. BS EN 16475-3:2016EN 16475-3:2016 (E) 7 1 Scope This European Standard specifies th
33、e requirements and test methods for draught regulators, standstill opening devices and combined secondary air devices that are used as components, carrying flue gases, in order to limit the draught in chimneys and provide secondary air to the chimney. Draught regulators, standstill opening devices a
34、nd combined secondary air devices for positive pressure chimneys are not covered by this standard. It also specifies the requirements for marking, manufacturers instruction, product information and attestation and verification of constancy of performance (AVCP). 2 Normative references The following

42、nd 1.0306 according to EN 10346 for any corrosion class for dry applications, and for wet applications, only for corrosion class 1 and 2, a steel according to EN 10088-1 of 1.4404 or higher. The draught regulator and standstill opening devices shall fulfil the following requirements, if appropriate.
43、 The combined secondary air devices shall fulfil the requirements of both, if appropriate. 4.2 Dimensions and tolerances The manufacturer is free to choose dimensions and tolerances for the manufacture of draught regulators and if appropriate standstill opening devices. 4.3 Mechanical resistance and
44、 stability The draught regulator, and standstill opening device, shall be able to move freely before and after the thermal tests except for a product designated As after a soot fire test. 4.4 Thermal performance 4.4.1 Reaction to fire As the fire reaction is not relevant for draught regulators and/o
45、r standstill opening devices, no declaration is necessary. 4.4.2 Fire resistance (internal to external) 4.4.2.1 General The manufacturer shall declare the minimum distance of the draught regulator, and if appropriate standstill opening device, to combustible material and the requirement of 4.4.2.2 a
46、nd if appropriate 4.4.2.3 shall be met at the distance declared by the manufacturer. For a temperature designation up to T450, a declaration of at least 400 mm for the distance to combustible material is deemed to satisfy this requirement without testing. 4.4.2.2 Heat stress The draught regulator, a
47、nd if appropriate standstill opening device, shall be tested in accordance with 5.1.3.2 and the requirements of 4.3 and 4.5.1 shall be met, and one of the flow rates of the group determination of 4.6.1, at the lowest declared setting, is within 10 % of the original value determined before thermal ex
48、posure. BS EN 16475-3:2016EN 16475-3:2016 (E) 9 4.4.2.3 Sootfire The draught regulator, and if appropriate the standstill opening device, designated sootfire resistant shall be tested in accordance with 5.1.3.3 and the requirements of 4.3 and 4.5.1 shall be met, and one of the flow rates of the grou
49、p determination of 4.6.1, at the lowest declared setting, is within 10 % of the original value determined before thermal exposure. If the product satisfies all criteria it may be designated G. If it only satisfies the criteria of 4.5.1 it may be designated As. Otherwise it may only be designated O. 4.5 Hygiene, health and environment 4.5.1 Gas tightness When a draught regulator, and if appropriate standstill opening device, is tested according to the test methods described in 5.1, the individual values of leakage rate shall not be v
