Kinsen KS-2408D Horizontal and Vertical Flame Test Apparatus is an inspection equipment used to evaluate the flame retardant properties of materials by simulating different combustion conditions to conduct flammability grading tests. Below is a summary of its core information:

I. Function and Principle

Testing Methods

Horizontal Burning Test: The specimen is placed horizontally, and a flame is applied to its free end to measure the flame spread rate and burning length.

Vertical Burning Test: The specimen is suspended vertically, and a flame is applied from the bottom to record the flaming/afterflame burning time and the ignition of drips.

Inclined Burning Test: The specimen is positioned at a 45° angle to comprehensively evaluate flame spread characteristics.

The equipment uses a Bunsen burner (flame height 20mm ± 2mm) to apply timed flames, recording parameters such as burning time and length to determine the material's flame retardant rating (e.g., HB, V-0, V-1, V-2, 5V).

Core Functions

Assess the burning behavior of materials (e.g., flame propagation rate, self-extinguishing properties).

Simulate the impact of initial fire flames on materials to evaluate their ignition hazards.

II. Technical Parameters

Flame Control: Gas source is propane or natural gas, with adjustable flame height of 20mm ± 2mm.

Timing Accuracy: Flame application time can be set from 0 to 99.99 seconds, with automatic recording of flaming/afterflame burning time.

Test Chamber: ≥0.5 cubic meters, equipped with a ventilation system to ensure sufficient oxygen supply.

Auxiliary Devices: Flow meter, pressure gauge, temperature and humidity conditioning chamber (23±2°C, 50±5% humidity), and desiccator.

III. Application Fields

Electronics and Electrical Appliances: Testing the flame retardancy of wires and cables, plugs and sockets, electronic enclosures, etc.

Building Materials: Evaluating the ability of insulation materials, fire-resistant materials, etc., to delay fire spread.

Plastics Industry: Conducting flammability grading for engineering plastics, foam materials, etc.

Other Industries: Safety certification for automotive parts, power tools, household appliances, and other products.

IV. Compliance Standards

International Standards: IEC 60695, UL94 (USA), ISO 1210.

Domestic Standards: GB/T 2408 (Plastics—Determination of Burning Behavior), GB 5169 (Fire Hazard Testing for Electrotechnical Products).

V. Importance of the Equipment

Safety Assessment: By quantifying the burning characteristics of materials, it reduces the risk of fire spread in case of fire. For example, flame-retardant materials can delay fire propagation, buying time for evacuation.

Quality Control: Provides data support for product development, production, and quality inspection to ensure compliance with domestic and international safety certification requirements.

VI. Typical Configuration

Core Components: Automatic positioning burner, electronic ignition device, cotton ignition test module, exhaust gas emission system.

Safety Design: Combustible gas leakage alarm, flame temperature monitoring, and anti-misoperation protection.

The Horizontal and Vertical Flame Test Apparatus is a key equipment for testing material flame retardancy, widely used in industrial production and safety certification fields, providing a scientific basis for enhancing product fire safety.
