FAQ
What types of textiles can be tested?
The tester is suitable for woven fabrics, knitted fabrics, coated or laminated materials, curtains, drapes, and other flame-retardant textiles.
What type of gas is required?
Industrial-grade propane or butane is used as the fuel source. The gas supply must be provided by the user.
How is the ignition angle adjusted?
The ignition system can be set between 0° and 90° relative to the sample surface to meet various standard requirements.
Can the flame timing be controlled automatically?
Yes, burn time, after-flame time, and smoldering time can be preset according to testing standards. All timers are integrated and programmable via the control panel.
Is the instrument safe and easy to operate?
Yes, the integrated design, high-quality stainless steel construction, and precise ignition system ensure safe, repeatable testing with minimal operator intervention.
