labratory gas fume chamber
The Gas Fume Chamber is designed to evaluate the color fastness of textiles and leather materials when exposed to combustion gases, including nitrogen oxides generated by natural gas or butane combustion. Samples are tested alongside a control fabric until the control reaches the specified fading standard, with discoloration assessed using a grey scale card.
The tester can continue repeated test cycles until the sample reaches the required color change, providing accurate and repeatable results for quality control, material certification, and R&D.
Applications
Testing color fastness of textiles and leathers exposed to gas fumes.
Assessment of resistance to nitrogen oxides produced during combustion.
Evaluation of fabric durability for urban, residential, or industrial environments.
Quality control in textile production, dyeing, and chemical finishing laboratories.
Standards Compliant
ISO 105-G02: Textiles – Color fastness to gases
AATCC 23: Color fastness to gas fume
BS 1006:1990-G02: Textile color fastness
GB/T 11040: Color fastness of textiles to gas smoke
Principle of Operation
Textile and control samples are placed in the test chamber and exposed to gas combustion smoke simultaneously. The color change of the control fabric is monitored, and the sample’s fading is compared using a grey scale card. If no color change is detected after one test cycle, the test can continue for the specified number of cycles until the desired fading standard is reached.
Key Features
Controlled Gas Combustion: Supports pure chemical butane or simulated urban gas.
Observation-Friendly: Chamber includes observation door for visual monitoring.
Accurate Temperature Control: Ensures uniform testing conditions at ≤60°C.
PLC Control System: Allows precise control of rotation, test cycles, and timing.
Durable Construction: Test chamber and components made of stainless steel (SUS) for long-term stability.
Repeatable Results: Automatic cycle continuation until the required color change is achieved.
