- This setup is designed to assess the horizontal burning characteristics of rigid cellular thermal insulation materials by exposing samples to a low-energy heat source. This test provides a relative measure of flammability and is influenced by the material's density, cellular structure, and thickness.
Key Components of the Setup:
- Test Chamber
- Dimensions: 600 mm (length) x 300 mm (width) x 760 mm (height).
- Material: Constructed from galvanized iron sheets with asbestos insulating boards lining the interior.
- Placement: Positioned within a fume cupboard to ensure a draft-free environment and natural air circulation around the specimen.
- Fuel Supply
- Gas Type: LPG gas with pressure-regulating and on/off valves for controlled ignition of the specimen.
- Burner with Wing Top
- Specifications: A standard gas burner with an internal diameter of 9.5 mm.
- Wing Top: Fitted with an attachment measuring 48 mm (internal length) x 3 mm (internal width) to ensure consistent flame application.
- Specimen Support Gauze
- Dimensions: 215 mm (length) x 75 mm (width) with a 13 mm right-angle bend for secure specimen positioning.
- Material: Made from 6.4 mm mesh gauze, crafted from 0.8 mm diameter steel wire.
- Gauze Holder
- Material: Mild steel, arranged horizontally and aligned parallel to the 600 mm length of the test chamber for optimal positioning.
- Timing Device
- Accuracy: Measures time with precision up to ±1 second to record burning duration.
- Measuring Scale
- Graduations: Marked in millimeters for precise measurements during testing.
- This setup is ideal for industries requiring detailed analysis of flammability in thermal insulation materials, ensuring compliance with safety standards in construction, automotive, aerospace, and more.
- The Equipment as per ASTM D635 /ISO 9772 / UL 94 can also be supplied.
