Flame retardant clothing flame retardant performance testing is generally in line with the standard GB/T 5455 "textile burning performance test vertical method" vertical method flame tester to test, this method can be used for flame retardant protective clothing cloth time, smoldering time , Determination of the length of damage.
First, flame-retardant clothing testing equipment
1. The test chamber of the vertical burner is a rectangular stainless steel box with dimensions of 329 mm X 329 mm X 767 mm in the box and 16 vent holes with an inner diameter of 12.5 mm uniformly arranged on the top of the box. In order to prevent the influence of the air flow outside the box, a top piece is installed 30 mm away from the top of the box, and six vent holes with an inner diameter of 12.5 mm are opened at the lower part of both sides of the box. The top of the box is equipped with a bracket to hold the specimen holder so that the specimen holder is perpendicular to the front door and is located in the center of the chamber. The bottom of the specimen holder is located 17 mm above the highest point of the igniter nozzle.
2. Igniter: The inner diameter of the TedeTal type is: 11mm; Tilt angle: >50.
3. Specimen holder: Used to fix the specimen, prevent curling and keep the specimen in vertical position. The specimen holder consists of two U-shaped stainless steel plates with a thickness of 2.0 mm, an inner frame size of 356 mm and a width of 89 mm.
4. Use of gas: propane, butane, liquefied petroleum gas
5. Weight (weight): With a hook, the weight can be hung on the lower side of the test sample side to determine the length of the damage. The weight is composed of 5 different qualities, and it is selected and used according to the quality of the sample body being tested. The quality is selected from the following table:
Second, prepare the sample
1. Cut the pattern to a size of 300 mm x 80 mm. The long side should be parallel to the warp or weft of the fabric.
2. For each set of test samples, 10 samples, 5 warp samples and 5 weft samples are generally taken. The warp samples cannot be taken from the same warp and the weft samples cannot be taken from the same weft yarn.
3. Before the test, the sample should be placed in a standard atmosphere with a temperature (20±2)°C and a relative humidity of (65±2)% for 8 to 24 hours (depending on the thickness of the fabric, the thin fabric can be used for 8 hours, thick fabrics). It takes 24 h). Then take out the sealed container. Can also be dealt with according to the conditions agreed by the parties involved, such as at 105 °C, ventilation drying th above, in the dryer cooling 0,5 h and so on.
Third, the preparation before the experiment
1. Prepare test specimens.
2, ready for test gas source.
3. Connect the air source to the instrument to ensure that there is no air leakage from the joint.
4. Connect the laboratory power supply and the instrument with the supplied power cord.
5. Place the textile sample in the sample holder and the lower edge of the sample should be flush with the lower end of the sample holder.
6, the test environment requirements: temperature of 10 ~ 30 °C and humidity of 30% ~ 80% RH in the atmosphere.
Fourth, test operation steps
1. Open the gas source valve.
2. Close the front door of the combustion chamber and turn on the instrument (power switch "1" side), the power indicator light.
3. Press the “Reset†button to return the burner to the ignition position (if no response, the burner is already in the ignition position, please proceed to the next step).
4. Press and hold the “Ignition†button to light the burner (Note: Keep the “Ignition†button pressed during ignition). After ignition, release the "Ignition" button. If it is difficult to ignite, adjust the "Flame adjustment" button (reducing the combustible gas flow clockwise and increasing the combustible gas flow counterclockwise). Pay attention to adjust the air flow while holding down the "Ignition" button.
5. Open the front door of the combustion test box, place the flame height ruler (height 40mm) in front of the flame by hand, adjust the “flame adjustment†knob, and adjust the flame height to 40mm±2mm. After the flame is stabilized, remove the flame height ruler. Hang the specimen vertically with the specimen holder in the center of the box and close the door.
6. Click on the "Start" button and the burner is moved to the sample suspension position (this time should be within 1 minute from the time the sample is taken out of the sealed container). After 12 seconds (or 10 seconds), the burner will stop. Gas and return to the "continuation time" automatically timed.
7. Observe the condition of the sample in the test chamber. At the same time when the continuous combustion is over, click on the “Continuous stop†button. If there is no continuous combustion, press the button “Continue stop†directly to automatically time the “smear timeâ€. When the smoldering is over, press the “Smoke Stop†button once, then record the continued burning time and the smoldering time, and record the phenomenon that appears during the test.
8, open the front of the combustion chamber to remove the specimen clip, remove the specimen, and then select the weight according to the weight of the fabric per unit area to determine the length of the damage (first along the long direction of carbonization fold off, and then at the bottom of the sample On one side, about 6mm from the edge of the bottom, hang a weight equal to the mass per unit area of ​​the sample with a hook, and slowly lift the other side of the lower end of the sample by hand, let the weight hang, and then lower, measure the sample The length of the disconnection is the length of the damage.).
9. Press the “CLEAR†button, the instrument will return to the initial state, open the test chamber door, remove the debris from the cabinet, open the ventilation equipment, exhaust the fumes and gases from the test chamber, and wait for the row to finish. Close the row. Wind equipment, this test ended.
10. If it is necessary to continue the test, the smoke, gas, and debris in the test chamber should be removed and the next sample tested. Repeat steps 3-9. If it is not needed, turn off the power (push "power switch" position "0"), then unplug the power cable, close the valve, and the test is completed.
11, continue burning, smoldering time should be recorded to 0.1s, damage length should be recorded to 1 mm.
V. Test report
1, the record of the sample: including the fabric type, name, organizational specifications and so on.
2, pretreatment conditions.
3. The duration of the ignition, the time of smoldering and the length of the demolition listed in the report shall be the average value of each sample, and the actual value of each sample shall be attached.
4. The afterflame time and smoldering time should be accurately recorded to 0.1 s in the report. The damage length is accurate to 1 mm.
5, the test environment temperature and humidity.
6, test date and personnel.
