1 General

TI1e contract provides for the testing of the fire resistance of a 300 mm thick, load-bearing, room

closing, heat insulating floor structure according to DIN EN 1365-2 : 2000-02 in conjunction with DIN

EN 1363-1 : 1999-10, in particular the determination of the fire resistance rating for exposure to fire

from the underside of the structure. The floor structure cornprised:

- a 200 mm thick reinforced concrete slab (concrete cover c = 35 mm) of concrete quality ~

C 20/25 - 100 mm thick Heraklith "Tektalan TK" segmented wood-wool panels in combination with

- Hilti IDMS insulating pins with 80 mm retention plates in galvanized zinc-plated steel and

- Hilti IDMR insulating pins in A2 stainless steel (material number 1.4301) with 80 mm retention

plates in galvanized zinc-plated steel.

The test was carried out as specified by DIN EN 1363-1, and comprised a comprehensive

description of the installation procedure and test conditions, and specification of the results obtained

for the structural component with which this report is concerned. The report does not cover possible

deviations from the standard regarding dimensions, structural details, loads, or stress or boundary

conditions, except those that are permissible under the test procedure for direct application to

similar, untested, floor structures.

Owing to the particular circumstances applying to the fire resistance rating test, and the problems

arising from these in quantifying the uncertainties involved in measuring the fire resistance rating, it

is not possible to specify a precise uncertainty range for the results.

The Materials Testing Institute Braunschweig (German: Materialprüfungsanstalt Braunschweig) was

not responsible for the choice of the test specimen.

2 Description of the test structure

The load-bearing, room closing, heat insulating floor structure to be tested consisted of a 200 mm

thick reinforced concrete slab (concrete cover c =35 mm) to which to a 100 mm thick Heraklith

"Tektalan TK" segmented wood-wool panel was fixed using Hilti IDMS insulating pins with 80 mm

retention plates in galvanized zinc-plated steel and Hilti IDMR insulating pins in A2 stainless steel

(material number 1.4301) with 80 mm retention plates in galvanized zinc-plated A2 stainless steel

(material number 1.4301).

The 200 mm thick reinforced steel concrete floor slab having the dimensions of 1910 rnrn x 5000 rnm

(W x L) was tested in respect of its qualities as a floor element in a horizontal position with line

loading according to DIN EN 1365-2: 2000-02. A Heraklith "Tektalan TK" segmented wood-wool

panel having the dimensions of 500 mm x 1000 mm x 100 mm (485 mm x 985 mm x 100 mm) (W x

L x H) was fixed to the reinforced concrete slab. The Heraklith "Tektalan TK" segmented wood-wool

panels consisted of an approx. 90 mm thick Heralan mineral wool fiber core positioned at right

angles to the surface of the slab and covered on both sides with approx. 5 mm thick magnesium

impregnated wood-wool cladding. The panel was. The Heraklith "Tektalan TK" segmented wood

wool panels were provided with a rabbet edge having a step width of 15 mm. To fix these, holes

(08.0 mm) were bored through the Heraklith "Tektalan TK" segmented wood-wool panels into the

reinforced concrete slab, in which the IDMS or IDMR insulating pins were driven using a hammer.

For each segmented panel, six IDMS or IDMR insulating pins (08.0 mm x 170 mm) and

corresponding retention plates (0 80 mm) were used. The positioning of the insulating pin dowels is

shown in Annex 1.2.

The gap between the floor structure and the wall was stuffed with mineral wool (material class A1

according to DIN 4102-01; melting point> 1000CC).

The test specimen was supported on a side wall of the furnace.

Note that a 50 mm thick Heraklith "Tektalan TK" segmented wood-wool panel was installed

additionally on the floor of the fire room. The temperatures measured at the top of the slab are given

in Annex 2.7.

Further details on the construction of the floor structure are given in Annexes 1.2 ff. of this report.

3 Test specimen and material properties

The strength and humidity of the test specimen at the time of testing corresponded approximately to

the values that pertain in normal use.

The material classification, data on specific weights per m2, absolute densities and humidity of the

test specimen and the building matertals contained in it are given in Annex 1.5.

4 Test layout and performance

The test specimen described in Section 2 was installed by the client's specialists in the form of a

horizontal room closure above a fire room having the overall dimensions of 4000 mm x 1910 mm

(Iength x width =Lexp x W exp) .

The floor slab was loaded by four line loads at right angles to it and positioned at 1/8 land 3/8 I (I = supported span) from each support. The line loads were applied via four load distribution beams and

two hydraulic presses, each with a total load of 39.89 kN, in accordance with the layout given in DIN

5

1045-1 : 2001-07 for the determination of breaking load (under consideration of the weight of the

slab itself and that of the loading equipment).

The fire room was flame heated in accordance with the standard temperature-time curve according

to DIN EN 1363-1 : 1999-10, Section 5.1.1. The temperatures in the fire room were measured using

six plate thermometers ("plates") with Ni-Cr/Ni-AI thermocouples (type K), D 1.0 mm, according to

DIN EN 1363-1 : 1999-10, Section 4.5.1.1, and positioned at a distance of a =100 mrn from the

underside of the heated surface as specified in DIN EN 1365-2 : 2000-02, Section 9.11(a).

During the test, the static overpressure in the fire room on the upper side of the test specimen

corresponded to the value given in Annex 2.11.

The temperatures in the layer between the concrete slab and the Heraklith "Tektalan TK" segmented

wood-wool panels were measured by 19 thermocouples as specified in DIN EN 1363-1, Section

4.5.1.2. Furthermore, the concrete slab was provided with three sensor cables, each having 5

thermocouples, to rneasure the temperatures at intervals of 10 mm from the underside of the slab.

The sensor cables were situated at intervals of Lexp/4 from one end, where Lexp is the length of the

slab. The temperatures on the unheated side of the test specimen were measured by one NiCr-Ni

thermocouple, IJ 0.5 mm.

Annex 1.2 shows the position of the measurement points.

The vertical deflection of the test specimen was measured at the center as specified in DIN EN

1365-2 : 1999-10, Section 9.3, and shown in Annex 2.9.

A schematic of the test arrangement, the position of the thermocouples in the furnace, the positions

of the pressure measurement points and that of the deflection point are given in Annexes 1.1 ff.

Test results and observations

The test results for the temperature rise above the initial temperature on the unheated side of the

test specimen, and within the body of the specimen, the temperatures in the fire room, the ambient

temperature, the deflection of the test specimen, the error function and the differential pressure are

shown graphically in Annexes 2.1 to 2.11.

The observations made during the test are shown in Annex 2.12.

(1) The test was terminated after 110 minutes, since most of the floor panels had fallen off.

On the basis of the test results obtained (see Tables 1 and 2) over the duration of the test from the

beginning of flame heating up to the end of the test of 110 minutes, it can be recommended that for

the floor structure tested with regard to load-bearing capacity, roorn closure and heat insulation, and

line loads positioned as for the determination of the breaking load (under consideration of the weight

of the structure itself and that of the loading equipment (see Section 4)), and exposure to fire on the

underside of the structure, it can be recommended in accordance with DIN EN 13 501-2 : 2003-12

that the structure be assigned the fire resistance class REI 90 or RE 90.

Range of applicability in accordance with DIN EN 1365-2 : 2000-02, Section 13

The test results are directly applicable to similar, untested, floor structures on condition that the

following applies with regard to the load-bearing component:

- The maximum moments and transverse loads on the test specimen are not exceeded, the

calculation of these being based on the method for determining the permissible load.

- The concrete cover must be c ~ 15 mm. For corrosion protection, layout of the reinforcement

cage, etc., further evidence of compliance is required.
