EN 16475-3:2016+A1:2018 (E) 5 European foreword This document (EN 16475-3:2016+A1:2018) has been prepared by Technical 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of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document includes Amendment 1 approved by CEN on 27 June 2018. This document supersedes !EN 16475-3:2016". The start and finish of text introduced or altered by amendment is indicated in the text by tags !". 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 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 national standards organizations of the following countries are bound to implement this European Standard: Austria, 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, Switzerland, Turkey and the United Kingdom.

EN 16475-3:2016+A1:2018 (E) 6 Introduction This standard forms a part of the series of standards for chimney accessories: — Part 1: Silencers — 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 negative 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 ventilation 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. SIST EN 16475-3:2016+A1:2019

EN 16475-3:2016+A1:2018 (E) 7 1 Scope This European Standard specifies the 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 and 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 documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Note 2 to entry: Measures to be taken after the event of a sootfire are to be found in the relevant product standard. 4 Product characteristics 4.1 General The draught regulator, and if appropriate the standstill opening device, housing and flap in contact with combustion products shall have a material with 0,6 mm minimum thickness, and a specification for steel according to EN 10088-1 of 1.4301, and 1.4404, and 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. 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 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 !The reaction to fire for draught regulators, standstill opening devices and combined secondary air devices should be declared: — after testing in accordance with EN 13501-1; or — by classification without further testing for materials which are by default classified A1. NOTE Classified without further testing or materials which are by default classified A1 (see Commission Decision [96/603/EC (2)]) no further testing needed." 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 and 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.

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 vary by more than 10 % of the average of the three samples tested for each size of draught regulator, and the average leakage rate shall not be greater than 0,06 m3/h per cm2 of free opening area, based on a pressure differential of (10 ± 1) Pa. The draught regulator and/or the standstill opening device tested for thermal performance shall meet this requirement both before and after the thermal performance tests (heat stress test and if appropriate soot fire test). The draught regulator and/or the standstill opening device designated As, shall have a leakage rate not greater than 0,18 m3/h/cm2 of free opening area, based on a pressure differential of (10 ± 1) Pa after the sootfire test. 4.5.2 Condensate resistance When tested in accordance with the condensate test of EN 13216-1 no condensate shall appear on the outer surface of the draught regulator/standstill opening device. The draught regulator shall be installed in accordance with the manufacturer’s instructions in the thermal test assembly of Figure 2, attaching the spray assembly to the top of the test chimney, and providing a drain for the condensate at the bottom. 4.5.3 Corrosion resistance Draught regulators shall be designated a corrosion class as defined in EN 1443 in accordance with 4.1. 4.5.4 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets.
