ISO 834 Small-scale fire resistance testing furnace for fire-retardant coatings
Product introduce
This instrument is applicable to the fire resistance performance testing of small samples of various fire-retardant coatings for steel structures used indoors and outdoors in buildings.It fully complies with the ISO 834 standard heating curve, making it an ideal solution for accurate and reliable fireproof performance testing.Compared with traditional large-scale test furnaces, this equipment delivers significant breakthroughs in footprint, operating costs, and gas consumption, making it the perfect tool for suppliers to conduct product development, quality validation, and simulation testing.
Ideal for:
Fireproof coating manufacturers Building materials testing organizations Steel structure fire protection companies Universities and research institutes
Equipment feature
1.Compliant with ISO 834 standard temperature curve — generates authoritative test data suitable for certification and official reports
2.It occupies little space; the area of a bedroom in a factory can be used to build it. occupies only 1/3 to 1/2 the space of conventional furnaces, easily fits in most laboratories
3.Substantially lower operating costs — significantly reduced gas consumption, with running costs only 40%-60% of traditional equipment
4.User-friendly operation ,lift-up furnace cover design and dedicated laptop platform for convenient specimen loading/unloading and real-time data monitoring
5.Stainless steel exhaust hood — effectively removes smoke and fumes, maintaining a cleaner and safer lab environment
6.The system consists of a robust furnace body + control cabinet with integrated design. It has been rigorously tested under high-temperature conditions and proven stable and durable.
7.This furnace is especially valuable for fireproof coating suppliers to perform daily simulation tests, formulation optimization, and new product validation — helping you iterate faster while keeping compliance and R&D costs under control.
Main Technical Parameters:
1.Instrument Composition: Composed of a horizontal fire resistance testing furnace(furnace internal dimensions
W×D×H=500mm×500mm×500mm), an gas heating unit, control unit, a temperature measurement system, and a pressure measurement system.
2.Temperature Measurement System:
2.1 Furnace Thermocouple: One K-type nickel-chromium/nickel-silicon thermocouple with a wire diameter of 3.0mm is used inside the furnace.
2.2 Back Flame Temperature Measurement: One large nickel-chromium/nickel-silicon thermocouple with a diameter of 0.5mm, fused to a 0.2mm thick, 12mm diameter circular copper
sheet, is used.
2.3 Furnace Temperature Rise Curve: The maximum combustion duration is 360 minutes, and the highest temperature is 1300℃. The temperature rise curve should be as shown in the
table below. The formula for the temperature rise curve is: T = 345 lg(8t + 1) + 20
Furnace temperature average: The difference between the thermocouple-collected
temperature and the standard curve is <100℃. The following rise control deviation requirements must be met:
de≤15% for 5＜t ≤10
de=15-0.5(t-10) % for 10＜t ≤30
de=5-0.083(t-30)% for 30＜t ≤60
de=2.5% for t＞60 Where: T is the average furnace temperature (℃), and t is the time
(min).
2.4 Furnace temperature acquisition: Type K armored thermocouples are selected. High
temperature resistance above 1300 degrees Celsius; the furnace temperature data acquisition
system has real-time curve and historical curve storage functions;
3. Pressure Measurement System:
3.1 Furnace internal pressure measurement: Measurement range 0-100Pa; uses an imported American differential pressure gauge with a T-shaped probe, measurement accuracy ±0.5Pa. It has overpressure protection function; if the furnace internal pressure exceeds 100Pa, the overpressure protection program will be executed, gas supply will be stopped, and the test will be terminated; conforms to ISO834-1 standard.
3.2 Furnace internal pressure is recorded every 1 minute, with an accuracy of 1 second. Data acquisition is 3 times/second. Furnace pressure control and data acquisition ensure that the
furnace pressure can be controlled in real-time according to the requirements of various standards in "Chapter 2 Compliance Standards" and form a control loop with the flue gas system;
3.3 T-shaped probe: uses a USU310S high-temperature resistant stainless steel tube, passing through the furnace wall from inside the furnace to the outside, maintaining the same
pressure level inside and outside the furnace.
3.4 Pressure transmitter: Alpha high-precision
pressure sensor from the USA. The pressure is 15 Pa ± 5 Pa for the first 5 minutes of the test, and 17 Pa ± 3 Pa after 10 minutes.
