Standards:

Applications:

The instrument is applied for the testing of fire hazard using com-bustible materials, like fabric or other similar functional materials.

Product Information:

Protective clothing flame spread tester is designed and manufactured according to the standard of ISO 15025 protective clothing burning test. It can test the state of flame spread of protective clothing under the impact of small flame. The instrument is a professional equipment, mainly applied for performance test of flame spread which protective clothing in fire by simulation technology.

FAQ:

What is its primary purpose and standard?

It evaluates the limited flame spread properties of vertically oriented protective clothing fabrics under a small defined flame, following ISO 15025:2016. It is not suitable for materials that shrink or melt extensively.

What are the two test procedures?

Procedure A (Surface Ignition) and Procedure B (Bottom-Edge Ignition) . The specific procedure depends on the intended end-use of the protective clothing.

What materials can be tested?

Single-layer or multi-component fabrics such as coated, quilted, multilayer, and sandwich constructions. This includes materials used in firefighter suits, welding uniforms, and chemical protective clothing.

What are the key test parameters?

A specimen (e.g., 560mm x 170mm) is exposed vertically to a 20mm high propane flame for 10 seconds. The test records afterflame time, afterglow time, and char/damage length.

What are the typical technical specifications?

Includes a stainless steel combustion chamber (e.g., 1200 x 600 x 1200mm), a 0.19mm burner nozzle, PLC touchscreen control, a timer with 0.1s accuracy, and supports automatic ignition
