3 1 0 Preface Certification Rules describe the conditions for certification of construction products by SP Certification. They consist partly of product-specific rules and partly of general rules as set out in CR 000. Certification rules are based on existing standards, but can be revised at any time in the future, for example to harmonise them with European or international standards. Updating may also be necessary if new regulations are introduced or as a result of experience of applying the rules. If clarification or expansion of the rules is necessary, they will be revised and published on SP s web site. Certification Rules no. 032, for fire dampers, have been approved and published by the manager of SP Certification. This version replaces assessment document PM 052.

4 2 1 Scope and intended application These certification rules govern requirements for fire dampers complying with EN and which are installed in ventilation ducts to prevent the spread of fire and fire gases between fire cells. 2 Technical requirements The requirements set out in these rules are divided into those concerned with the properties of the dampers, and those concerned with the components of the dampers. Unless otherwise stated, the requirements relating to properties apply to the entire damper system, which consists of the fire damper, connected to the ventilation duct, and associated components required for installing the damper in a fire separating part of the building structure. Appendix 1 sets out requirements relating to the Swedish Planning and Building Act and the Swedish Building Regulations. 2.1 Properties Requirements relating to properties are taken from the building regulations BFS 2011:6 (BBR) with amendments from the Swedish Board of Housing, Building and Planning and from EN Declaration of certain properties is voluntary, as set out below Protection against the spread of fire and fire gases Systems that meet the requirements are given the same fire rating class as that of the part of the building structure that they penetrate. Applicable fire resistance classes are EI 15, EI 30, EI 60, EI 90 and EI 120, in accordance with EN Fire dampers and safety distances to escape routes and combustible material Class E systems can be used in Class EI parts of buildings if the required distance to escape routes and combustible materials can be maintained. Determine the minimum safety distance (from the damper blade when closed) to combustible material and to escape routes in accordance with the analytical design rules as set out in Section 5:112 of the Building Regulations. Use an emission factor value of 1.0 and a critical radiant intensity of 2.5 kw/m 2. However, regardless of the calculated result, the safety distance must under no circumstances be less than 50 mm. If dampers with a safety distance are to be used as end device, input data from temperature measurements of damper blades is needed, but this is not normally included as a part of fire testing in accordance with EN If the safety distance cannot be assured, e.g. by means of a protective grille, a clear warning sign must be fixed to the damper or in its vicinity, easily visible to users of the premises. A protective grille must always be fitted when the damper is used as a end device.

5 Fire dampers in combination with fire-insulated ventilation ducts Class E fire dampers in combination with fire-insulated ventilation ducts may be used in penetrations through Class EI structures in accordance with the conditions set out in the (Swedish language) handbook Installationsbrandskydd Ventilation Rör [Fire Protection Systems - Ventilation Ducts] (ISBN: ), Section Fire resistance of system components Materials and components used in the damper must be of Class A1 or A2-s1, d0 in accordance with EN CE-marked performance can be accepted. Smaller parts such as sealing strips, intumescent strips and electrical installations may be made of combustible materials: see the Swedish Building Regulations, Section 5: Air leakage around damper blades Air leakage around damper blades must be declared in accordance with EN 15650, Section 5.5 a. The minimum permissible value is Class 2 in accordance with EN Perform tests to determine the minimum and maximum values, in accordance with EN 1751 or EN Dampers with Class 3 or Class 4 performance must be tested in accordance with EN Air leakage, blade frame Air leakage around the frame must be declared in accordance with EN 15650, Section 5.5 b. Perform the tests in accordance with EN 1751, Classes A, B or C. Test the smallest frame size Pressure drop across fire dampers at various flow rates The pressure drops in accordance with EN 15650, Section 5.5 c may be declared. Perform tests in accordance with EN Opening or closing torque The values of opening and closing torques, in accordance with EN 15650, Section 5.5 d may be declared. Perform tests in accordance with EN Coefficient of thermal transmittance The value in accordance with EN 15650, Section 5.5 e may be declared. Perform tests in accordance with EN Sound power level The value in accordance with EN 15650, Section 5.5 f may be declared. Perform tests in accordance with EN ISO Emissions (materials) Damper components must not emit hazardous substances that could adversely affect air quality in buildings occupied by persons. See the Swedish Building Regulations, BBR, Section 6:11. The information provided in a product s manufacturer s declaration of conformity can provide the basis for assessment. 3

6 Microorganisms Installations must be so designed that the quality of indoor air cannot be affected by microorganisms to such an extent as to present a risk to human health or cause an unpleasant smell. See the Swedish Building Regulations, BBR, Section 6: Protection against trapping Consideration must be given to guarding against the risk of injuries caused by trapping etc. See the Swedish Building Regulations, BBR, Section 8.3.
