The flame spread tester is a specialized instrument used to evaluate the flame spread characteristics and flammability of materials under specific conditions, such as controlled flames, thermal radiation, or gas environments. Its core function is to simulate fire scenarios, quantify parameters such as flame propagation speed, combustion time, and damage length during material combustion, and provide scientific basis for the evaluation of material safety performance. This instrument is widely used in fields such as materials science, safety engineering, and fire safety standard development. It is a key tool for the research and development of fire-resistant materials, product quality control, and safety certification.

1、 Principle

Ignition and combustion simulation:

The instrument ignites the material sample through ignition devices such as electric heating wires and gas spray lamps, simulating the source of fire in a real fire.

Flame propagation observation:

The sample may be placed horizontally or vertically to test the flame spread performance in different directions.

Data collection and analysis:

High precision sensors monitor parameters such as flame front position, combustion time, and afterburning/smoldering time in real-time.

Environmental simulation:

Simulate different fire scenarios through atmosphere control systems or use radiation panels to provide thermal radiation, in order to more accurately reflect the response of materials in a fire.

2、 Characteristics

High precision and automation:

Adopting high-precision timers, automatic positioning burners, and data acquisition systems to reduce human errors and improve testing repeatability.

Multifunctionality and flexibility:

Support multiple testing modes (such as surface burning, bottom edge burning), adjustable flame height, burner angle, and sample size to meet different material requirements.

Safety and Environmental Design:

Equipped with exhaust vents, testing chambers, and flame-retardant materials to reduce the impact of smoke generated during combustion on the environment.

3、 Application Fields

Textile and clothing industry:

Evaluate the flame retardant performance of textiles such as protective fu, curtains, and curtains to ensure they meet safety standards.

Building and Decoration Materials:

Test the flame spread speed and total heat release of walls, floors, insulation materials, etc. in a fire to provide safety guidance for building design.

In the field of transportation:

Evaluate the combustion characteristics of car interiors, high-speed train materials, and ship decorative panels to ensure they meet strict safety regulations.

Furniture and daily necessities:

Detect the combustion performance of furniture such as sofas and mattresses to reduce the risk of fire.

Fire product certification:

Provide testing data for the research and certification of fire protection products such as fire-resistant coatings and flame retardants, and promote technological progress in the industry.
