What are the commonly used vertical flammability chambers for textiles?
For most textiles, burning performance is one of the main indicators, so it is very necessary to carry out related tests. So, what are the commonly used Textile Vertical Flammability Chambers?
Vertical B Hypnosis T US East Time:
lhaTextile Testing Instruments, Testing Equipment Manufacturer Ignite the sample directly from the vertically suspended sample strip, and test the aging time, smoldering time, and damaged length or area of the sample to evaluate the flame retardant properties of the textile. This method is suitable for detecting the characteristics of burning childrens clothing, decorative fabrics, laminated fabrics, and coated fabrics. Compliant standards are ASTM D6413-99, DOC-FF 3/71, CALIF TB-117, IOS 5455, CPAI-84.lhaTextile Testing Instruments, Testing Equipment Manufacturer lhaTextile Testing Instruments, Testing Equipment Manufacturer The test instrument is a vertical flame tester. It is mainly composed of stainless steel combustion chamber (with observation doors and windows), automatic ignition system, timing system, sample fixture, gas supply system, etc. After the standard ignition time, the buttons on the control panel and the timing display device can accurately record the afterburning and smoldering time of the fabric to determine its combustion characteristics.
Horizontal flammability test:
lhaTextile Testing Instruments, Testing Equipment Manufacturer For the horizontally placed sample to be ignited to the standard time, the flame diffusion distance and time are measured, and the flame diffusion rate of the flame is used to characterize the flame diffusion characteristics of the fabric. This method is suitable for testing various types of textiles, especially automotive interior fabrics. Compliant standards are: ISO 3795, FMVSS 302, DIN 75200, SAE J369, ASTM D5132, JIS D1201, AU169, FZ/T 01028.
The test instrument is a horizontal flame tester. The instrument is equipped with a sealed stainless steel combustion chamber and observation window, which can resist high temperature and high pressure. It has a suspended tympanic membrane structure with steel springs and a shock absorption system to ensure smooth operation. It is equipped with a sample holder and a door burner, the sample holder can move up and down, left and right. The basic mode is equipped with manual timing control. Equipped with an automatic gas control system including electromagnetic control gas valve, automatic ignition timer and controller.
45D agrees with C misplacement T US Eastern time:
lhaTextile Testing Instruments, Testing Equipment Manufacturer Ignite the sample placed at a 45 degree direction, measure the time required for the flame to burn a certain distance on the sample, or measure the reburning and smoldering time, the damaged area and damage time after burning the sample, or burn the measured sample to the lower end of the sample The number of times the flame needs to be cleared at a certain distance. This method is suitable for the flammability test of textiles. Compliant standards are: ASTM D0, FTMS 191-5908, CFR 16 Part1610, CAL IF TB117, NFPA702, IOS 14644.lhaTextile Testing Instruments, Testing Equipment Manufacturer lhaTextile Testing Instruments, Testing Equipment Manufacturer The test instrument is a 45-degree textile flame tester, and its configuration is similar to the above two combustion testers. They all include ignition system, timing system, gas supply system and basic combustion chamber and bracket. According to the standard, the ignition time is much shorter than the above two instruments, usually 1 s. After igniting the fabric, burn it onto the cotton thread and blow off the cotton thread to reduce weight, thereby triggering the stop switch, and the display shows the burning time.lhaTextile Testing Instruments, Testing Equipment Manufacturer lhaTextile Testing Instruments, Testing Equipment Manufacturer The above is the operating instructions of Textile Vertical Flammability Chamber introduced by Shanghai QINSUN.
