UL94 Cellular Plastic Horizontal Burning Test Chamber Flammability Tester

Product Overview

The Cellular Plastic Horizontal Burning Test Chamber is designed for laboratory evaluation of the horizontal burning characteristics of small cellular plastic specimens.

The tester provides a controlled combustion environment for comparing the burning behavior of cellular plastic materials with a density below 250 kg/m³. It is suitable for flammability testing, material screening, fire performance evaluation and product safety testing.

The chamber integrates a precision burner, gas supply, adjustable flame, specimen support mesh, lighting and exhaust system. Its integrated ignition design helps provide a stable and repeatable flame application during testing.

Key Features

• Designed for cellular plastic horizontal burning tests
• Suitable for UL94 flammability testing
• Test application related to ISO 9772
• Adjustable methane, mixed gas or propane supply
• 38 ± 2 mm blue flame
• Automatic combustion/self-extinguishing time measurement

• Compact integrated chamber design for laboratory use

Test Configuration

The test chamber provides the main components required for controlled horizontal burning evaluation:

• Burner: ISO 10093:1998 specification
• Gas flow: 965 ± 30 ml/min
• Gas pressure: 0.1 MPa
• Flame height: 38 ± 2 mm
• Specimen-to-burner distance: 13 ± 1 mm
• Combustion timer: 0–9999 × 0.1 s
• Support mesh: Stainless-steel wire
• Observation: Built-in chamber lighting
• Ventilation: Integrated exhaust fan

The ignition system incorporates a 0.1-second combustion time delay to help ensure stable gas ignition before the test sequence begins.
