Single - Chip Control Horizontal Vertical Flammability Test
Equipment Corrosion Resistant
The tests are to comply with UL1581-2001 section 1060) vertical
burning and FT1 test), 1061
(cable burning test), 1080 (VW-1 burning test), 1090 (electric
appliance horizontal burning test),
1100 (Horizontal sample / FT2 combustion test) requirements.
This experiment mainly consists of the following major components:
1, the test box:
A, the test box made of 304 stainless steel, with a beautiful
appearance, rust and corrosion
B, the top of the box is equipped with ventilation and exhaust
system, after the test can be
exhausted to the outdoor exhaust (such as environmental
requirements, can do another
environmental treatment system)
C, the front of the box has a tempered glass observation door, easy
to observe the test situation
D, the operation panel is located on the right side of the
observation door, easy to operate.
E, test box specifications: 180CMX130CMX180CM, volume: 4.2M3;
2, the control system:
A, the control system using single-chip control, push-button
selection switch to select a different
test mode to meet the needs of the standard, test time, number of
Time, etc. can be set to keep burning and record. Delayed
combustion timing using
photosensitive automatic control, according to test conditions
automatically stop timing and
B, equipped with high-precision flame control system, can
automatically and accurately record
the burning time after stopping the fire, without manual recording,
to reduce test error.
C, equipped with temperature measurement system, can accurately
control and debug the test
required for the test temperature.
1) Thermal sensors (copper conduits and thermocouples) - The
conduit structure shall be
electrolytically copper of very high conductivity. 1.75 grams of
catheter flame is 20mm,
The flame of the 10-gram catheter is 125 mm.
2) K-type thermocouple, with 0.5mm diameter stainless steel tube
3) intelligent temperature control table and K-type thermocouple to
match. The reading can reach
more than 1000 ℃.
3, the test device and test fixture:
A, the main fixture: the sample holder and the burning torch
B, sample support: made of 304 stainless steel, sub-level bracket
and vertical bracket
C, combustion burner: to meet the requirements of ASTM D 5025-99,
the standard power:
