3m cubic smoke density fire detector for cables to BS 6853

Introduction

3 Metre Cube is used for measuring the emission when the cable or optical cable is placed horizontally under the definite fire condition. The equipment comprises a cubic enclosure and a photometric system.
The specified standard fire source (ethanol 90±1%, methanol 4±1% and distilled water 6±1%) 1L±0.01L is burned.
 

Standards:

IEC 61034 - 1 & 2 Measurement of Smoke density of cables burning under defined condition.
BS 6853 Code of practice for fire precautions in design and construction of passenger carrying trains.
