Building materials non-combustibility tester is designed to test
the combustibility of main components in homogeneous and
nonhomogeneous building products under specific conditions. This
instrument belongs to the grading testing equipment of building
combustion performance. The tester in the furnace temperature (750
+ 5 )℃, uses modular temperature controller to measure precise test
results, and then decides the grade of the sample according to the
grade A (homogeneous materials) specified in “GB/T 8624-2012
Classification of combustion performance of building materials and
GB/T 5464-2010 Classification of combustion performance of building
materials and products.
1, Probe test points: test chamber, test center, specimen surface,
2, Heating power: 1200W
3, Temperature range: (- 200 ~ 1300) ℃
4, Temperature control range: (300 ~ 750) ℃
5, Temperature measurement accuracy: ± 1 ℃
6, Temperature control accuracy: ± 3 ℃
7, The initial furnace equilibrium temperature: (750 ± 5) ℃,
temperature drift in 10 minutes ≤ 2 ℃. The relative average
temperature in the maximum deviation of 10min can not exceed 10 ℃.
8, Furnace temperature stabilizing time: stabilizing time from room
temperature to 750 ℃ ≤1 hour.
9, Heating furnace tube size: diameter (75 ± 1) mm, height (150 ±
10, The sample is cylindrical: diameter 45mm, height (50 ± 3) mm;
11, Temperature probe: diameter 1.5mm, wire diameter 0.3mm, nickel
chromium - nickel silicon armored thermocouple;
12, Power adjustment: 0 ~ 1200 W adjustable;
13. Condition adjustment: Before the test, the sample must be
adjusted in a ventilated oven at a temperature (60 ± 5 ° C) for (20
to 24) h, and the sample is then allowed to cool down to room
temperature in a dry dish. Before the test, the quality of each
sample should be weighed , accurate to 0.01g.
14, Power supply voltage: AC220V 50Hz;
1, Heating furnace shell, holder, air hood and test stand are made
of stainless steel, beautiful shape, smooth lines, corrosion
resistant, anti-aging, durable.
2, Electrical box shell uses spray method, namely the electrostatic
powder coating method, making the chamber appearance of excellent
quality, strong mechanical strength, anti-corrosion, no rust.
3, Electric spiral lifter. In the process of the test, one operator
is enough, greatly saving manpower and time. The integrated design
of holder and heating furnace increases the stability of the lift
rod. The test piece is put into the furnace with an accurate
4, The heating furnace is equipped with refractory tube of electric
heating coil, with insulation layer on the outer cover, so that the
outer wall will not appear high temperature phenomenon during the
test process due to the temperature rise of the furnace, increasing
equipment safety performance.
5, The test equipment is designed with a 80mm × 120mm gate in the
bottom of the blocking flow screen. The residual sample drops to
the bottom of the device can be directly removed from the gate to
facilitate the calculation of the quality loss of the specimen.
6, An observation mirror is set in the front top of the tester,
convenient for quick observation of the progress of the sample
inside the furnace.
7, There are many kinds of upper machine choices for test
equipment. One is the computer control interface, and the other is
the man-machine touch screen interface. The user can choose to use
