The 45 degree automatic flammability tester is designed as an integral box, mainly composed of a control system and a combustion chamber. The sample is installed on a sample holder inclined at an angle of 45° in the combustion chamber, the burner is close to the sample, and the sample is ignited with flame for a specified time after returning, observe the combustion of the sample and the spread speed of the flame on the sample, and evaluate the ignitability and flame spread performance of the sample. The 45° automatic flammability testeris from Wewon Tech suitable for the determination of flame retardant properties of clothing fabrics, decorative fabrics, tent fabrics, etc.
The Wewon’s 45 degree fabric flammability tester is an integral box-type design, mainly composed of a control system and a combustion chamber. The mechanical part is made of stainless steel processing technology. The shape is exquisite and it is resistant to flue gas corrosion. The control system has a high degree of automation, the key components are imported parts, the digital display time, the three-dimensional adjustment of the fixture, the automatic control of the test program, the observation and recording are convenient to use, stable and reliable.
Specimen Holder Inner Frame Size:
Between the Nozzle and Surface of the Sample: 8 mm
Cotton Sewing Machine Thread:
30 KGS → 45 Degree Automatic Flammability Tester
Combustion Air Supply:
Under the specified conditions, place the sample at an angle of 45°, ignite the sample for 1 second, and the time required to burn the sample upward for a certain distance with flames is used as a measure for evaluating the intensity of the textile’s burning.
1. Burning Intensity and Speed Test
For fabrics with raised surface, the ignition or melting of the base fabric is used as an additional indicator of the intensity of combustion.
Under the specified test conditions, the textile sample in the 45° direction was ignited, and the afterburning and smoldering time, damaged area and damaged length of the fabric after burning were measured.
2. Damaged Area and Damaged Length Test
Under the specified test conditions, ignite the textile sample in the 45° direction, and measure the number of times the fabric needs to touch the flame at a distance of 90 mm from the lower end of the sample.
3. Number of Exposure to Flame Test
This material is mainly used to test the flame retardant properties of textile materials, toy fabrics, upholstered furniture fabrics and other fabrics.
The ASTM D1230 textiles testing for flammability test chamber is used to measure the flammability of clothing textiles and to evaluate the three grades of the flammability of clothing and textiles. It is suitable for measuring the intensity and speed of combustion of flammable textiles after ignition. Install the sample on the sample holder inclined at an angle of 45° in the combustion chamber, make the burner close to the sample, ignite the sample with flame for a specified time and return to observe the combustion of the sample and the spread of the flame on the sample speed to evaluate the ignitability and flame spread properties of the specimens.
Flammability Test Chamber
Made of heat-resistant and smoke-resistant materials, the size of the test room is 370 mm × 220 mm × 350 mm, with a tolerance of ± 10 mm.
An observation door made of heat-resistant transparent material is arranged at the front of the box, and a ventilation strip is arranged at the bottom of observation door.
There are 11 or 12 evenly spaced 12.7 mm diameter ventilation holes behind the top of the test room.
It consists of two U-shaped steel plates with a thickness of 2.0 mm, the size of the inner frame is 152 mm × 38 mm, the specimen is fixed in the middle of the two plates, and the two sides are clamped with clamps.
