Thermocouple Thermometer
do thermocouple, thermistor or glass thermometer have linear thermometric propeties?Why?
None of them are really linear, but the glass thermometer comes the closest. But even if the material in the glass expanded linearly, the glass itself expands - both the bulb area and the tube, and that would distort the linearity.

K-Thermocouple thermometer - AVR test
Fire Resistance:
Fire resistance:
Introduction:
This paper discusses fire resistance test for beams and columns as described in the British standards EN 1365. for both cases the fire resistance of specimen is tested in a furnace where load is added and the specimen heated, temperatures are recorded during heating and as the specimen deforms this indicates the strength of the specimen, the following is a discussion on how the test should be undertaken for both column and beam.
Requirements:
These standards of testing the fire resistance of a specimen are provided in the British standard EN 1365 part 3, according to this standards general requirements that are provided in EN 1363-1 and EN 1363-2 must be followed, according to EN 1365-3 testing for fire resistance of specimen involves heath hazards where toxic gases may be emitted and also disposal of residual may cause health hazards.
Safety precautions:
- EN 1363-3 provides safety precautions and what should be done to avoid health risks
- Adequate training should be provided to the technicians
- The instructions provided in the standards must be followed at all times by the technicians
Beams:
The main aim of this test is to check the integrity of a beam that will be constructed to support a floor or roof
Specimen:
- If the beam is longer than the furnace then the length that is exposed should be greater than 4 meters
- If the beam is twice the length of the furnace then the beam should be tested for shear strength and also bending moments
- The fire exposed length (span) of the beam should be at least 4 meters long
- If the beam under normal construction contains joints then these joints must be incorporated at span (exposed length) or as appropriate under normal construction
- This case shows a case where the beam is exposed to fire on three sides and the fourth supports the roof, the roof weight is represented by the associated construction that will be placed on top side of the beam
- This test is not applicable to pre-stressed concrete beams
The associated construction:
- The associated construction is the construction that represents the load on the beam under normal circumstances example roof or floor; the following are the conditions of this construction:
- It should be constructed in discrete sections
- It should contain discontinuous reinforcements
- Made or aerated concrete slab
- Density should be 450 – 850 kegs per meter cubed
- Maximum width should be 600mm
- Thickness should be 175 – 125 mm
- Should be placed symmetrically to the axis of the beam
- The size of the beam will also be determined by the furnace size and design.
Fire protection material:
Specimens are sometimes sealed with fire protection materials; if these materials are applied then they must be applied on the entire length of the specimen
Where a void or hole is created in the beam the hole should not extend outside the furnace
Gaps that may exist between the furnace wall and associated construction shall be sealed
Installation of the specimen:
- The ends of the beam should be sealed with fire protection material to prevent gas linkages
- Joints that may be incorporated should also be sealed
- Ends of the beam shall be sealed with mineral wool
- Mineral wool should be 90 mm to 110 mm thick and density should 90 to 150 kg per meter cubed
- Finally the specimen should be mounted horizontally
The load (associated construction);
- The load should match the expected load that the beam is expected to bear in practice
- The load which is the associated construction should be placed uniformly on the beam and should cover at least 500 mm on the span.
Temperature:
Thermocouples or plate thermometers will be used to measure temperature, in this case there should be at least two thermocouples for every meter of the specimen.
They should be placed 100 mm below the surface below of the beam and 100mm from each end of the beam
When the beam is 500m thick or greater then they will be placed on the side (mid height) of the beam and not the lower side
If the specimen is made from inert material such as steel and aluminium then their properties are known and the temperatures can assist in detecting failure
Deflection:
The beam is expected to deform as temperature increases, zero deformation however should be recorded as the nature of the axis before the test
The performance of beam will be judged with reference to loading capacity
Reporting:
Reports regarding such test should specify that EN 1365-3 standards were used.
Factors that may affect the fire resistance of beam include:
- The Cross sectional area of the beam
- Thickness of fire protection material used
- Density of material
- Moisture content of the beam and coating material
The diagram below shows the standard procedure of testing the fire resistance of a beam
Columns:
Specimen:
The section that is exposed to heat should be at least 3 meters long
The specimen may be placed in the furnace whereby one end may be pin jointed and the other restrained or both ends restrained
The ends of the specimen must be sealed with mineral wool to prevent gas losses
The load applied to the specimen must be parallel to the axis of the specimen.
If joints are incorporated then they will be placed at mid height and coated with fire protective material
The specimen shall be placed vertically
End conditions:
End conditions are that if one end is pin jointed then the end will comprise of a cylindrical rolled, hinges must be accurately located on the axis of the column, if the ends are restrained then they must be fully restrained.
Report:
Reports regarding such test should specify that EN 1365-3 standards were used.
The test applied to:
Columns that are fully exposed to fire on three sides and the test will depend on end conditions; small amounts of friction that may emerge at the ends will considerable increase the load bearing capacity of the test specimen.
Temperature:
Temperature will be measured using thermocouples or plate thermometers, these devices will be placed ¼, ½ and ¾ of the length on the exposed part of the column
Thermometers should be at least placed 50 to 150 mm from the column facing the column. Also if column is made of composite material example steel and concrete then temperature for individual components is important
Behaviour after heating:
The specimen is expected to deform, and therefore zero deformation sill be measured before the beginning of the test and deformation will be measured using a dial gauge.
This will result due to a number of factors, one is because the moisture is lost and the specimen shrinks, loss of moisture will result into a decline in the cross sectional area and therefore loss of strength.
For materials such as steel columns, they will expand and will contract as the column deflects. Steel tubes filed with concrete will expand and still be able to hold the concrete inside, however further heating will result into deformation, steel tubes filled with timber then the initially there will be no change but further heating deformation will occur.
The diagram below demonstrates the fire resistance test for a column:
