Product Description
Product Overview

The ISO 5659-2 / ASTM E662 NBS Smoke Density Test Chamber measures the optical density of smoke generated when a test specimen of a specified thickness is exposed to a radiant heat source or open flame inside a sealed chamber. The ASTM E662 furnace delivers a heat flux of 2.5 W/cm² (2 kW/m²), while the ISO 5659 conical radiant heater allows adjustable irradiance levels of 10 kW/m², 25 kW/m², or 70 kW/m² to meet different testing requirements.

ISO 5659-2 ASTM E662 NBS smoke density test chamber with sealed test cabinet, radiant cone heater and optical measurement system
Applicable Standards
  • ASTM E 662 — Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials.
  • ISO 5659-2 — Plastics — Smoke generation — Part 2: Determination of optical density by a single-chamber test.
Structural Design and Construction
  • The tester comprises a test cabinet, specimen holder assembly, radiant cone heater, ignition system, light source and measuring devices, plus the associated control components.
  • Ergonomic structural and control design: the test box features a full-door design with a locking mechanism for one-time secure closure, streamlining operational procedures.
  • The fully opening door allows easy loading and unloading of samples and convenient cleaning of the chamber interior.
  • The front door is hinge-mounted with a viewing window, fitted with an opaque movable visor to prevent light from entering the sealed test box.
  • The controller is mounted on the side of the cabinet for easy operation and remains visible even when the door is closed.
  • Safety flameout board is simple to replace, ensuring safer operation.
  • The test box interior is easy to clean and coated for chemical resistance.
