AB  - Passive fire protection is civil engineering discipline which is very popular for research and development of new construction products and test standards. The primary function of passive fire protection product is to achieve the declared fire resistance. Fire resistance of a construction product is expressed as a time interval (30 min, 60 min, 90 min, 120 min ...) in which certain properties of the tested product are preserved. In the given time intervals, it is necessary for the tested product to maintain the thermal insulation properties (I), integrity (E) and additional properties prescribed by the test standard related to the tested product.  The fire damper represents part of HVAC system installed on walls which are fire resistance barriers [2]. Additional properties related to fire-resistant service installations- fire dampers (hereinafter only fire dampers) are the leakage on the fire damper in the cold state and the leakage of fire damper (S) during the fire test. In order to determine the previous properties, a test installation for fire dampers was formed, which consists of: installed damper in the test wall, duct and pipeline system, system for measuring the volume flow, cooler and a fan. All the obtained results are graphically presented in the paper and serve for the purpose of determining the mentioned fire properties of dampers and for the purpose of fire resistance classification of construction products.

AB  - The growing expansion of construction and import of new, as well as existing materials from around the world, has led to a large number of tests materials and elements of constructions in the Republic of Serbia. Most of these materials and building constructions have test certificates obtained in foreign laboratories, which mostly refer to European standards. The currently valid Rulebook on mandatory attestation of elements of standard building structures for fire resistance and on working conditions that must be met by organizations of associated labour authorized to attest these products from 1990 requires testing of each product, or structural element, according to the domestic SRPS standards. The condition for accessing the European Union requires the harmonization of regulations related to the testing of construction products. Therefore, the IMS Institute, the Ministry of Interior - Sector for Emergency Situations and the Ministry of Construction of the Republic of Serbia have written a new draft Rulebook on Technical Requirements for construction products for which performance characteristics are important: reaction to fire, fire resistance and external fire performance. The plan is to publish the Rulebook, as valid, at the beginning of 2022, with a transitional period for implementation of two years. The paper presents a overview of the new Rulebook.

AB  - The thermal conductivity of a material is the parameter that is most reliably determined experimentally. The problem of determining the thermal conductivity in the soil is greater because the soil is heterogeneous, so for the same soil this parameter may be different depending on the their ohysical characteristics. Therefore, it is necessary to adopt an appropiate model for describing the thermal conductivity of the soil for a particular location after the necessary tests are performed. This paper is based on experimental measurements of soil thermal conductivity as a function of moisture content in the area of the ,Nikola Tesla Airport construction site in Surčin and the adoption of one of the existing theoretical models that would satisfactorily describe changes in thermal consuctivity. Based on the obtained results of experimental reasearche, a two- parameter fitting of the measured values of thermal conductivity of the soil was performed in Cote-Konrad model, which proves to be reliable and the simplest to describe the thermal properties of loess in the area of Belgrade.

AB  - Tehničko rešenje predstavlja poboljšanu konstrukciju zaštićene grejne ploče (hotguarded plate) za merenje toplotne provodljivosti termoizolacionih materijala
postavljanjem ispitnog uzorka iznad i ispod grejne ploče (standardna simetrična
ispitna konfiguracija). Merenje toplotne provodljivosti vrši se u skladu sa
standardom SRPS U.A2.020.
Ovim rešenjem toplotna provodljivost se proračunava na osnovu vrednosti
izmerenog toplotnog fluksa korišćenjem dva tanka toplotna fluksmetra na toploj
i hladnoj strani ispitivanih uzoraka. Prednost korišćenja fluksmetara na grejnoj i
rashladnoj ploči u odnosu na uobičajen metod za određivanje toplotne
provodljivosti (hot-guarded plate) je u periodu dostizanja stacionarnog stanja koji
je znatno kraći. Na taj način bi se ostvarila sva zahtevana merenja toplotne
provodljivsti termoizolacionih materijala usled povećane potražnje za ovakvom
vrstom ispitivanja u Republici Srbiji.
Kod metoda merenja sa toplotnim fluksmetrima, uobičajeno je da se koristi jedan
fluksmetar na zaštićenoj grejnoj ploči. Kod ovog tehničkog rešenja koriste se dva
toplotna fluksmetra na površini uzorka. Na taj način se precizno može utvrditi
srednja vrednost toplotnog fluksa kroz ispitivani uzorak tj. srednji toplotni fluks
kroz sam uzorak je tačnije određen. Fluksmetri za ovakvu vrstu merenja su
odabrani sa velikom mernom površinom da bi se dobile što merodavnije
vrednosti raspodele toplotnog fluksa po mernoj površi, pri čemu uobičajeno
korišćenje znatno manjih toplotnih fluksmetara.
Novi koncept grejne ploče ne odgovara uobičajenim grejnim pločama koje su
opisane u standardima. Specifičnost ovog dizajna ploče je u smanjenom
toplotnom prekidu – prostor između unutrašnje zaštićene (hot) i spoljašnje
zaštitne (guard) ploče koje zajedno čine predmet ovog tehničkog rešenja.
Veličinom toplotnog prekida od 1 mm popunjenog dvokomponentnim
termoizolacionim lepkom, određena je i minimalna dozvoljena debljina uzorka. 
Na taj način je omogućeno merenje tanjih termoizolacija, tj. povećan je merni
opseg samog uređaja pri ovakvom načinu izrade grejne ploče.
Dodatna prednost u pogledu konstrukcije toplotnog prekida je u formiranju
stepenika čija je osnovna svrha formiranje jednodelne konstrukcije koja se sastoji
od zaštićene (hot) i spoljašnje zaštitne (guard) ploče. Uobičajeno se ovakve ploče
izrađuju iz više segmenata dok je specifičnost ove konstrukcije da se sastoji iz
jednog dela.
Temperaturska razlika između dve ploče se kontroliše korišćenjem termoparova
u diferencijalnom spoju koji su raspoređeni po obimu kontakta dve ploče.
Merenjem naponskog signala za praćenje temperaturne razlike između pomenute
dve ploče mogu se proceniti lateralni gubici između zaštićene i zaštitne ploče i
izmereni naponski signal se može koristiti u svrhe upravljanja.
Grejači zaštićene i zaštitne ploče su ukopani u materijal grejne ploče i napravljeni
su korišćenjem žice za izradu termoparova K tipa. Grejači su vezani na standardni
priključak za termoparove tipa K, koji je fiksiran za grejnu ploču. Preko fiksiranih
priključaka ostvareno je napajanje grejača naponskim dvokanalnim nezavisnim
izvorom. Korišćene su rashladne ploče koje su hlađene korišćem automatzovanog
rashladnog kupatila sa propisanom površinskom fluktuacijom temperature
rashladne površi od 0,1°C.
Validacija grejne ploče je izvršena učešćem u međulaboratorijskom poređenju.

zaštitne (guard) ploče koje zajedno čine predmet ovog tehničkog rešenja.
Veličinom toplotnog prekida od 1 mm popunjenog dvokomponentnim
termoizolacionim lepkom, određena je i minimalna dozvoljena debljina uzorka. 
Na taj način je omogućeno merenje tanjih termoizolacija, tj. povećan je merni
opseg samog uređaja pri ovakvom načinu izrade grejne ploče.
Dodatna prednost u pogledu konstrukcije toplotnog prekida je u formiranju
stepenika čija je osnovna svrha formiranje jednodelne konstrukcije koja se sastoji
od zaštićene (hot) i spoljašnje zaštitne (guard) ploče. Uobičajeno se ovakve ploče
izrađuju iz više segmenata dok je specifičnost ove konstrukcije da se sastoji iz
jednog dela.
Temperaturska razlika između dve ploče se kontroliše korišćenjem termoparova
u diferencijalnom spoju koji su raspoređeni po obimu kontakta dve ploče.
Merenjem naponskog signala za praćenje temperaturne razlike između pomenute
dve ploče mogu se proceniti lateralni gubici između zaštićene i zaštitne ploče i
izmereni naponski signal se može koristiti u svrhe upravljanja.
Grejači zaštićene i zaštitne ploče su ukopani u materijal grejne ploče i napravljeni
su korišćenjem žice za izradu termoparova K tipa. Grejači su vezani na standardni
priključak za termoparove tipa K, koji je fiksiran za grejnu ploču. Preko fiksiranih
priključaka ostvareno je napajanje grejača naponskim dvokanalnim nezavisnim
izvorom. Korišćene su rashladne ploče koje su hlađene korišćem automatzovanog
rashladnog kupatila sa propisanom površinskom fluktuacijom temperature
rashladne površi od 0,1°C.
Validacija grejne ploče je izvršena učešćem u međulaboratorijskom poređenju.",

AB  - The Guarded hot plate method (GHP) is a widely used technique to measure thermal conductivity of thermal insulation specimens in steady-state conditions. In this paper, an advance of GHP has been developed in the Laboratory for Thermal technique and fire protection in Institute IMS. The innovative GHP has been applied for measuring thermal conductivity using additional heat flux meters. The design of this GHP is similar to the design of the plate for GHP apparatus; however, it has different design: smaller width of thermal barrier, which is filled with insulation glue. Heaters inside hot and guard plates are built from wire for thermocouples, which is a unique type of heater. Geometry of heater has been optimized inside plates to achieve uniform temperature distribution along the specimen surface. Temperature uniformity of guarded hot plate and energy balance were experimentally determined. The verification and validation results of improved GHP have been shown. The test method was validated comparing test results of thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by guarded hot plate method. The measurement was performed on the same specimen of thermal insulation material (expanded polystyrene) according to SRPS EN 12667 at temperatures ranging between 10℃-40℃. The measured thermal conductivity of all participants in the round-robin test was input data for statistical processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the “z” score has been used. Measurements were conducted successively for all participants. Since 2020, the Accreditation Body of Serbia also approved this test method.

AB  - To reduce occurrence of fires in buildings as efficiently as possible, it is necessary to take into account active and passive fire protection measures during construction of building. This paper will show more about passive fire protection measures related to the selection of adequate material to be used during construction, which contributes to the localization of fire and prevents it from spreading to other rooms and facilities.
All products, which are planned by project, must have adequate certificates not to contribute to the development of fire, as well as to meet the class of fire resistance. In the Republic of Serbia, only the Laboratory for Thermal Engineering and Fire Protection, within the IMS Institute, deals with this type of testing and issuing reports.
This paper will present test methods for obtaining a fire reaction class. After the tests, according to the standard SRPS EN 13501-1, a Classification Report is issued in which the final fire reaction class is given for the tested product whose validity lasts for 5 years.

AB  - Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent the fire from spreading to other rooms. In this paper, the experimental analysis of fire resistance of non-load-bearing wall with dimensions 3000 mm x 3000 mm thickness 200 mm were presented. The wall was made from clay hollow-brick masonry blocks with dimensions 500 mm x 200 mm x 249 mm (L x D x H) with mortar on both side of wall of thickness 15 mm. The wall was exposed to a standard fire test according to SRPS EN 1363-1:2014. The temperatures on the unexposed side of the wall were measured in thirteen positions with thermocouples (K – type) according to the national standard SRPS EN 1364-1: 2014, and at the junction between mortar and clay hollow-brick. Deflection of the wall in five places was measured also. Obtained results depending on the time of reaching the critical temperature during the fire test were presented.

AB  - The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Greeds Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature distribution is evaluated in the general form and expressed in the terms of the convolution integrals. The GF are employed in the novel approach for calculation of Thermal Response Factors (TRF) with arbitrary shape functions for unsteady heat conduction in composite planar structure. The two pairs of TRF for spatial and temporal distribution of the temperature and the thermal flux are obtained. The whole analysis is performed in the time domain. A numerical scheme for efficient evaluation of convolution integral suitable for practical application in the case of the long term measurements with lower sampling rates is developed. The in-situ measurements of inside and outside surface temperatures and outside heat flux for a building wall under real dynamical environmental conditions during the period of then days are used for validation of the presented results and to demonstrate the possible practical application. Using developed approach and recorded surface temperatures as inputs the temporal and spatial distributions of the temperature and the thermal flux are obtained. These results are compared with experimental data and numerical simulations obtained by the Finite Volume Method (FVM).

AB  - The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Green's Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature distribution is evaluated in the general form and expressed in the terms of the convolution integrals.
The GF are employed in the novel approach for calculation of Thermal Response Factors (TRF) with arbitrary shape functions for unsteady heat conduction in composite planar structure. The two pairs of TRF for spatial and temporal distribution of the temperature and the thermal flux are obtained. The whole analysis is performed in the time domain. A numerical scheme for efficient evaluation of convolution integral suitable for practical application in the case of the long term measurements with lower sampling rates is developed. The in-situ measurements of inside and outside surface temperatures and outside heat flux for a building wall under real
dynamical environmental conditions during the period of then days are used for validation of the presented results and to demonstrate the possible practical application. Using developed approach and recorded surface temperatures as inputs the temporal and spatial distributions of the temperature and the thermal flux are obtained.
These results are compared with experimental data and numerical simulations obtained by the Finite Volume Method (FVM).

AB  - In this paper, results of a long term experimental in-situ measurement of air
temperatures and heat fluxes trough a building wall surfaces, are presented. Indoor and
outdoor measurements were carried out simultaneously during the period of 1 month in
a dwelling of residential building located in Belgrade, Serbia. The data were used to
calculate the thermal transmittance of the wall according Standard ISO 9869-1:2014.
The U-value obtained from the experimental data and those calculated in steady-state
temperature regime are compared. Criteria for the data that have to be met in order to
get accurate U-value are discussed.

AB  - This paper is presenting a method for temperature transfer function (TTF)
estimation by filtering an experimentally collected data. The experimental data were
obtained in simultaneous measurements of inside and outside temperatures variations
during the period of 3 months of a building located in Belgrade, Serbia. The TTF
estimation is based on Wiener filtering technique for the dynamic systems with finite
impulse response (FIR). TTF is derivate in time and complex domain and the correctness
of the acquired transfer function is tested on the new input data set. The estimated TTF in
complex domain is used to get decrement factor (DF) and time lag (TL) between the
temperatures.

AB  - In this paper, the results of numerical simulation of 2D non-stationary
temperature fields in commonly used composite structural members made of steel and
concrete in fire conditions were presented. Simulation is based on the model which
includes temperature dependence of physical parameters of materials, specific heat and
thermal conductivity. Analysis of composite structural members comprises determination
of a heat flux field which additionally facilitates understanding of region and geometry of
heat flow, thus enhancing fire protection design. Initial temperature distribution is
adopted as uniform, according to Eurocode. Fire conditions were according to ISO 834.
The FEM computations for different protection scenario and protective materials for
partially encased I section - are conducted in ABAQUS. Obtained results can be used in
cost optimization of fire protection measures.
