NBS Smoke Chamber Upgrade

ISO5659-2, BS6401, ASTM E648, IMO FTPC PART 2, NFPA253

The usefulness of the smoke chamber may be extended in several ways.  The important revised version, according to ISO 5659 Part 2, can be supplied as part of a new Smoke Chamber or as a retro-fit to all existing Aminco, Newport, Stanton Redcroft, FIRE or Govmark smoke chambers.

This test method has now been adopted by the International Marine Organisation (IMO) and is known as IMO FTPC Part 2.

The Cone Heater Module has been designed for use in the Smoke Density Test. It incorporates the specified truncated cone radiant heater, which is horizontally mounted in the chamber. The specimen is mounted beneath the cone heater also in the horizontal configuration.

Electrical: 230 volts AC 50 Hz – Fuse Rating: Anti-Surge 10 amp fuse

Ambient Temp: Operating 10°C to 35°C

Dimensions: Apparatus – 400 mm (W) x 800 mm x (H) x 300 mm (D).
Control module – 400 mm (W) x 500 mm x (H) x 400 mm (D)

Gas Supplies: The preferred pilot burner gas supply is a mixture of Air and Propane. The propane should be supplied at a pressure of 350 mm water gauge and the Air should be supplied at a pressure of 17 m ± 3 m water gauge as detailed in the ISO standard

Water supply: The heat flux meter requires water-cooling. A simple re-circulating pump, water reservoir and connecting pipe-work is adequate.
