Common flammability tester for textile flammability testing

Author: Date :2022-05-31 Views: order

1.  45 degree burning test method:


Ignite the sample placed in the direction of 45 degrees, and measure the time required for the flame to burn upward for a certain distance on the sample, or measure the afterburning and smoldering time, damage area and damage length of the sample after burning, or measure the burning time of the sample. The number of times the flame needs to be released at a certain distance from the lower end of the sample. This law applies to the flammability test of textiles for consumption. Compliant standards are: ASTM D1230, FTMS 191-5908, CFR 16 Part1610, CAL IF TB117, NFPA702, GB/T 14644

The test instrument is a 45-degree combustion tester, and the configuration is similar to the above two combustion testers. All contain ignition system, timing system, air supply system and basic combustion chamber and bracket. According to the standard, the ignition time is much shorter than the above two instruments, generally 1s. After the fabric is ignited, it burns to the cotton thread, the cotton thread burns and the weight falls, which triggers the stop switch, and the display shows the burning time.


2. Vertical burning test method:


Ignite the sample from directly below the vertically hanging sample strip, and test the afterburning time, smoldering time and damage length or area of the sample to evaluate the flame retardant properties of textiles. This method is suitable for testing the combustion characteristics of children's clothing, decorative fabrics, laminated fabrics, coated fabrics, etc. Compliant standards are ASTM D6413-99, DOC-FF 3/71, CALIF TB-117, GB/T 5455, CPAI-84.

The test instrument is a vertical combustion tester. It is mainly composed of stainless steel combustion chamber (equipped with observation doors and windows), automatic ignition system, timing system, sample fixture, gas supply system, etc. After the standard ignition time, the afterburning and smoldering time of the fabric can be accurately recorded through the buttons of the control panel and the timing display device, so as to judge its combustion characteristics.


3. Horizontal flammability test method:


For the horizontally placed sample ignition to the standard time, the spread distance and time of the flame were measured, and the flame spread rate was used to characterize the flame retardant properties of the fabric. This method is suitable for testing all kinds 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 combustion tester. The instrument is equipped with a sealed stainless steel combustion chamber and observation window, which is resistant to high temperature and high pressure. It has a suspended eardrum structure with steel springs and a damping system for smooth operation. Equipped with a sample holder and a door burner, the sample holder can be moved up and down and left and right. Basic mode comes with manual timing controls. Equipped with automatic gas control system including electromagnetic control gas valve, automatic ignition timer and controller.
