ISO 5659-2 ASTM E662 NBS Smoke Density Chamber Versatile Fire Testing Instruments

ISO 5659-2 ASTM E662 NBS Smoke Density Chamber Versatile Fire Testing Instruments

Introduction:

The NBS smoke density test chamber is a cutting-edge fire safety instrument engineered to meet rigorous international standards, including ISO 5659-2 and ASTM E662. Designed for precise measurement of smoke optical density and toxic gas extraction, this chamber is indispensable for laboratories and manufacturers testing solid materials under flaming and non-flaming conditions. Its dual-configuration system supports horizontal radiation cones (50KW/m²) for ISO 5659-2 and vertical furnaces (25KW/m²) for ASTM E662, ensuring versatility across global testing protocols.

Features:

• Dual Heat Sources: Switch seamlessly between ISO 5659-2 (horizontal radiation cone) and ASTM E662 (vertical furnace) via aviation connectors.

• High-Precision Optics: Equipped with an S-4 photomultiplier tube and ND2 neutral filter for light transmittance accuracy up to 0.0001%.

• Safety Mechanisms: Explosion-proof design with pressure relief ports and replaceable safety devices.

• Automated Control: Integrated touchscreen computer for real-time monitoring, test customization, and data logging.

• Self-Cooling System: Eliminates external water dependency with a self-circulating cooling water source.

Technical Specifications:

• Chamber Dimensions: 914mm (W) x 914mm (L) x 610mm (H), constructed with thick stainless steel and Teflon-coated interiors for corrosion resistance.

• Thermal Output: 50KW/m² (ISO 5659-2) and 25KW/m² (ASTM E662).

• Optical System: Uniform incandescent light source with automatic gear switching (Clear/Filter/Dark) based on smoke density.

• Compliance: Meets ISO 5659-2:2017, ASTM E662, NES 711, and GB/T 8323 standards.

• Optional Accessories: Printer for instant reports, NES 711-compatible burner, and stirring fan.
