27m³ cable smoke density tester according to IEC 61034-1&2

Introduction

27 Metre Cube Smoke Density Test Chamber 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
